Greg and Katie, I've changed my mind about changing the injectors in your D4. After watching your video for the fourth time, I think you've a low compression piston causing the gray smoke at start-up. It kind of clears its self up after the engine warms up. (be aware you engine does burn a little engine oil and oil level should be checked twice a day when being operated. But Greg, go very sparingly with the starting fluid. Two little squirts in the top of air cleaner ( it's the round thing right in front of you) should get you up and running. A little to much can get you a bent connecting rod and that means an engine overhaul. I forgot to mention the fuel filters; change them when you service the engine, at oil change time. Oh, if you don't have a hydrometer, NAPA has a very reliable one for the right price. Drain the Cooling System including the Block and replace the fluids with a 50/50 mix of antifreeze and fresh water and add a pint of "cooling system conditioner". About your Dozer Hydraulics, I got a better look at the Pump which kind of looks like a Hydreco. There should be a plate on the outer face of the pump. Hydreco is a little on the expensive side and it can be replaced with one of several other aftermarket brands that will pump about 25-30 gallons per minute and pump against 2500 PSI Head. I can't recommend you install a Piston or Vane Pump. A gear pump is the right choice and it should match the coupler on the front of the Crankshaft. I'm guessing you have a spline coupling. Now about your Hydraulic Spool Valve which currently, only lets you operate one implement, the dozer up and down. I would suggest you check out any scrap yard for at least a three function control valve so you can operate other attachments. Your dozer isn't Cat. It appears to be an aftermarket angle blade. The diagonal brace on the right side (it comes down from the right top of the back side of the moldboard (the dozer blade) and attaches to the top of the right side push beam. That diagonal brace can ne modified by adding a hydraulic cylinder for Tilting the blade - not angling the moldboard, just tilting. It make dozing so much better. A Cat 930 wheel loader's steering cylinders would make an inexpensive addition to a smoother operating dozer. Got any question? I'll always give you guys a straight up answer. Have Fun and keep sending your weekly videos.
HUGE amount of help here! thank you so much! I am going to have a good start to bringing this old machine back to life thanks to you!
I like to see you go repair it. That will make a good video. Hopefully, it will be worth their time buying it.
Exciting!!!
So. Greg has a new hobby, restoring the bulldozer. And Katie’s hobby is restoring the camper. First step change all the fluids……. Good luck
Another score for you guys. Great asset when Greg figures it all ready for another 70! Hope your spirit for adventure lasts as long as your list of chores.
I’m sorry but I’m crying with laughter, never have I had so much fun watching one of your videos. I hope to see this little beastie more often. Stay well.
Little red tractor says "hold my beer..." and gets the job done :D love it.
We also now know where the word head lights originated! Classic sketchy stuff you crazy kids! ❤
Theres nothing wrong with being 70 years old...lol 😂😅 I resemble that remark. 😢 We had a D4 as well on our dairy farm many years ago, an excellent machine that could almost run forever. Loved the fun ya'll had pull stsrting it, thankfully older vehicles have clutches...Love ya'll ❤
I can relate. At 70 I'm difficult to get started too. With that optimistic can-do attitude, y'all will have it running with a turn of a switch soon enough. Good going you two.
Until you’re able to get the pony motor working, I suggest figuring out how to engage and disengage the compression release from the operators position. If successful, you can use it to get the engine to start turning over easier, then while turning over release it and add fuel. It will be less of a shock on you and the engine.
^^ totally agree
No need to blast the drivetrain by dropping the clutch. Just leave her in neutral and use the compression release - I believe that's how it was designed to work on all the stuff with pony motors
I was puckered every time he slammed it into gear (or dumped the clutch, couldn't tell which). Parts are hard to find for these old things, and splitting the tractor to replace the pressure plate because you sheared the bolts off the release fingers is NOT fun ... ask me how I know LOL
Usually the man see a potential toy he wants, but in this case it was you Katie, I love that! Love the risks you take, but it’s another great addition to the family.
Wow. That's got to be almost the exact same era of D4 that we used to pull a bus up a mountain road onto our property. It's not ours -- it's our neighbors -- but we can attest that the thing is a workhorse and you are going to get some great use out of it, I'm sure!
Wow, that's awesome
Watching Starting the Cat #6. Greg put the transmission in 2nd or 3rd gear. don't use the two steering clutch levers except to steer. Use the shorter lever (master clutch) Try third gear first. When in first and towing to start there is just too much gear reduction.
We have been starting it in 5th, less resistance in the higher gear, and it starts easy!
I don’t know about this exact dozer, but on some old dozers the pony motor wasn’t just to crank over the main engine to get it started. The pony motor was started and allowed to run for several minutes before trying to start the main dozer engine because, they shared the same cooling system. So when you allowed the pony motor to operate for about 10 minutes, it actually pumped antifreeze through the main engine block heating everything up making it easier to start the main engine. If it’s colder out, you might try using one of the handheld propane torches to warm up the intake manifold on the main engine right before you try starting it.
And don't forget the Ether Bunny! Everybody says don't use Ether on a Diesel engine, but Matt says otherwise at dieselcreek.
I love those "rounded" rocks. I would be digging those out, they`re beautiful!
I had a couple of those back in the 80s for a fire wood business. Great little cat's. One the pony motor worked well,the other we pull started. About 6 feet in 3rd an it popped off. Thanks 👍 for sharing.
Greg & Katie, don't forget to cover the top of the D4 exhaust pipe to keep water from getting in the engine. Water down the exhaust can also cause lots of expensive problems in the engine.
You are MY FAVORITE channel to watch! Your willingness to plow forward with a smile is infectious... congrats on new addition to help you build and grow farther for your dreams of life off grid...❤ keep sharing we'll keep watching ❤❤❤
I worked for CAT for a decade, and the pony motor is pretty easy to fix or replace with a rebuilt or working Pony motor. The pony motor heats the block so the diesel engine will start in cold weather. You need it, or convert it to an electric start. I wouldn't recommend you stand with your feet under the blade held up by only a chain or steel rope, if you want to keep them. This was built when I was born, and handles about like me, but it will need some maintenance; oil chances, lubs, cleaning, and track has too much sag; otherwise you'll throw a track off, CAT is great for getting you part as you need them, anywhere in the world. So, take advantage of them when you need help.
I've just looked at your video the the 5th time and can tell you for sure the dozer cylinders are Bailey tie bolt style. I'm 99% sure if you and find the part number stamped into the outer barrel of the cylinder, I can give you the Packing kit parts number and Bailey's phone number.
Suggestion. Run the bulldozer (blade up) up and down your road to pack down the sand. Then use your tractor again and then the bulldozer again. It’s only temporary anyway as that sand will wash…you need something to stabilize both the road and the bank.
Hello Greg and Katie. I think you should upgrade to electric start or at a minimum fix the pony motor. Also if you are trying to start the beast, make sure you are in second or third gear and get it rolling good and pop the claim if you are too slow it jump, spurt, fart smoke and die. Think about new hydraulic hoses and reroute so they won’t hang up.
I believe you two are adventurous. It must be fun because both of you are smiling. The bull dozer is a great addition to your homestead. The old ones are simpler to work on by a diyer. Must be a UA-cam video somewhere about working on it! 😁💖💖 The goats are like little boys looking for mischief. So cute. Peace Love Happiness 💕💕
Once Greg gets a handle on how to operate and get the pony motor fixed to start it, got through the hydraulics for the blade, you will have a great machine to get work done on the property. I must say, it never gets old watching your videos, always a new adventure.
Needs converted to electric start
12000 lbs with dozer
Put it in 5th gear it will turn easyer
And then they will have dead batteries during the Winter. Much better to fix the pony@@wilmamcdermott3065
To quote the old TV series, The A Team, it's good when a plan comes together.
You people are my A Team!
Vary good idea to purchase the BULLDOZER. Now, the two of you can do so many different projects that were out of your realm of possibility before. I'm so happy for you both!
I can see you putting it under cover somehow and then spending the winter getting it refreshed... then come Spring - WATCH OUT!! I'd love to see you shine her up a bit and do that maintenance you were talking about... only to get her absolutely covered in mud come rainy season. Congrats on the new addition to your fleet.
Don't forget to pull the compression release when you are trying to start it
Hello from Germany from Kakenstorf Hans and Oci...you are crasy...we Love it...❤❤❤👍👍👍❤❤❤
Good morning
Greg and Katie, a lot of love will help this old lady!
Kate, you sent him to go and a bottle of milks, and he return with massive dozier... keep hold of the purse. At best he would remain busy and busier.
There is a gasoline engine on the side called a "Pony Motor". First you crank it up and then engage it with the diesel engine. After the diesel warms up it is ready to go to work. I ran a D-4 for years and that is the correct way to start it.
Talk (is cheap) to a pro about the beast and what needs to be done immediately, near term and long term. Budget constraints?? Also, can you keep it covered from inclement weather?? Otherwise, it will just keep deteriorating. Good luck!!
Hi guys, new subscriber, awesome buy, you’ll have a lot of fun on that old girl. Just be careful around that blade when it’s slung that way because if the hydraulics have backed off and that sling is taking the load, if the sling snaps and you have any part of your body under it, you’ll be a limb short. Take care from Australia
I love the bulldozer purchase. Please trust me on this one: “you need to purchase the book or manual on this dozer, it will save you a lot of problem solving down the road (no pun intended) if you really want to put it to it’s maximum potential”. These older tractors have a lot of quirks that can cause frustration, that’s why you need the original manual on the machine.
I was a little confused for a moment. I thought I was watching Ambition Strikes. Good Luck
We may need their help 😅
Do the simple and commonsense items first. Especially with winter approaching. Clean out the dirt and debris with a leaf blower. Power wash. Check fluid levels and greas nipple points. Identify and fix leaks based on priorities, costs, skill level, tools. Check belts and wiring condition. Replace as required.
Easy start is a main one. Confirm how viable the first stage motor is. Get that resolved and working. An easier fix might be the blade's leaking hydraulic hose.
Fix up the hydraulics being that you got leaks you're probably getting air in your hydraulic lines and when it hits the air pocket it drops it fix all the hydraulic leaks Just like in a power steering if you're low on power steering oil you know what your power steering like in your vehicle gets jittery motor spins faster until it gets oil
Love you guys always impress us as viewers , always improving your homestead always smiling, just addictive viewing and admiration for you both
Hi from Australia again
Katie and Greg u 2 are quickly becoming the new darlings of the internet with everyone cheering you on
I noticed on the first pull after you unloaded it from the ramp truck, that when Greg was putting the chain around the blade to pull it , he stood there with both feet underneath the dozer blade, please make a note never to do that again. It was good that the strap holding up the blade didn't break when Greg's feet were under it.
I could but I won't. This machine needs lots of work and $$$. Broken front leaf springs to start. Worn drive sprockets. Track tension adjusters are questionable. Shall I go on? I do not want to rain on your charcoal but when was the last time this machine had a full service? I wish you luck with your newest investment. Buy a case of tube grease and a case of starting fluid.
This is absolutely the best you tube video ever posted. Rolling a bill dozer down a hill to start it? I had never thought of that? . The pony motor is definitely the best way to start it. The engine sounds really good. They definitely made them to last back then. You need some lead off ditches about every fifth feet to move the water off the road instead of just letting the water run down the road as is currently happening.
Congrats on the Cat. I am 15 years older than your Cat and sometimes need a kick to start. Ron PTL USA
Great video, definitely shows your persistence and how working together gets things done. Be careful with the dozer and thanks for sharing.
Looks like there is water in the fuel. Need to bleed the filter until you see diesel. Check the engine oil, do a full filter service, check the fuel tank for water too. Hydrolic level does it need any? Transmission level? Air filter need cleaning or replacing? Check the track chains for wear, clean the zerks off and give some grease. How old are the batteries? Is the alternator working/charging? Clean and secure the posts and clamps. Radiator water what color is it? Check for antifreez, or add some.
I noticed the D4 dozer has a pony motor, the blue smaller one on the right side. I watch a lot of Diesel Creek w/Matt and he has a huge collection of earth moving toys. You start the pony motor first, which will assist starting the Caterpillar's largeer diesel. Enjoy the vidoes.
The pony motor won't start it. We think the belt is too loose because it seems to get it close but just won't turn over
With winter approaching fast can you get the dozer under cover somehow, perhaps where that old sawmill is, then you can work on it in more comfort, going through and repairing its faults as much as you can, ready to put it to work next year.
Now Gregg can wreck lots of things. Hopefully fix some roads and stuff.😅
Looks like the first job on the dozer is to tension up those tracks. I believe it's fairly straight forward. Then you can sort out the hydraulics.
Yes very cool i am so happy you bought a dozer this will change everything from removing snow to snaking wood out to for a sawmill and firewood and cutting roads and whatever you come up with i am so happy for you guys
Many mechanics on here with great input on what your dozer needs and tips for operating. Depending upon what you're planning to use it for, and for how long, a worn-out dozer may suit your needs at a low price. If you plan to keep it and fix it up, it'll take $$$, but to clear some stumps and rough grade your lot before passing it on to someone else, it's perfect.
You guys crack me up. Never a dull moment in your Off Grid Life!!!
I agree with most of the comments. But if you dont want to address the pony motor right away, take time to adjust those tracks. It is is simple with a grease gun and proper fitting on gun. If track comes off you cannot pull start it to get it running.
So is that blue engine on your left the 'pony' motor. I rebuilt and repaired a lot of starters in my time but that is a first. I have sold electric conversions for a couple of CAT's. You are going to have a lot of fun with this, be prepared to do a lot of re-do's till you get the hang of dirt moving. Enjoy!
I love the "home brew" pony motor and hydraulics ! If the belt is slipping on the pony, start looking for double sheeve pulleys. Hopefully you can find a hydraulic expert who can help you out there.
A little TLC and that dozer will last a long time !
P.S. Get proper chains on all 4 wheels of that tractor before the snow flies !
Blade dropping issue: I have never operated a D4 Cat but almost all dozers have a full forward fourth float position that puts the hydraulics in 'neutral' allowing gravity control (most useful when back dragging). Looks like you are working in 2nd or 3rd gear? Keep it in low when learning and digging. Most important, stay calm and don't get aggrivated. You certainly picked a tough job to learn on!
Looks like a great addition for your property maintenance and project management.
The pony motor is designed to pre heat the diesel main engine. It has to bring up water temp and oil pressure before the main diesel will start. They are temperamental. Patience is the key.
My d4 is basically the same model as yours.
This is very exciting from my favorite venturesome couple! I suspect you will be able to get all the helpful advise on the repairs needed and possible upgrades to your new, old, D4. I know Greg will be able to fix the hydraulics and the pony engine issue. Greg made me laugh while trying to start and then the initial operating. He looked like a mad scientist at the contols and I'm sure he was both emotionally and mentally stressed and tired after the road work. For as complicated as it appeared, I suspect it really is pretty basic operationally, just needs more seat time to get it all figured out and used to it. I'm looking forward to seeing what all you will be using this new tool for on your property. I know it will be a real time saver for you and feel it was a good decision to make this investiment. Have a good week ahead and be safe. Larry, Central Valley, Ca.
I have operated old d8h and an old d7 fighting wild fires
Does anything you guys do ever go without a hitch! Your guys rock. No matter what, you just keep on plugging along. Keep it up. ❤
Greg,& Katie, good purchase (Bulldozer). Gotta say, watching Greg maneuver that machine was nerve racking. I know you’re very capable, hearing you say it was terrifying let’s me know that you’re very aware. Wishing y’all luck with maintenance. Praying for your safety always.💯😱🙏🏾✝️🙏🏾🇺🇸
Good luck getting your dozer running
Hi guys. Another great video. You guys really need to talk to Matt on the Diesel Creek channel. If anyone can give you some good advice on getting a bulldozer that old up and running it’s him. Good luck with it. Looking forward to seeing some great videos coming out of that dozer.
Yes Matt would be a good person to give you some help on the old iron !! 🤔
Back when you're done was built, diesel engine were lower compression than they are now. The starter engines exhaust runs threw the diesel engine's intake manifold to heat it so the diesel will start Easier. Without the starter motor running, it will be very hard to start even by pulling it. Normally it is not to hard to get the starter motor to run.
You should talk with Matt at Diesel Creek and have him guide you. He seems to be a Great Guy. Love both of your channels. Tks for sharing.
Found this on the net. May be useful - Power Shift? Engine Running .. Can all the detents on the shifter be felt in all ranges..If not check linkage
Next step.. pull transmission oil filter and magnetic strainer
Iron or steel pieces or parts..transmission problem
Bronze pieces...clutch failure
Brite steel pieces..pump failure
Aluminium pieces..torque converter
Rubber pieces..seals, o rings or hose failure
I like your old dozer. With a few fixes there is a lot work that can be done with her. BUT BE CAREFUL A LOT OF THINGS CAN GO WRONG IN A HURRY.
Especially working on a mountainside. Take your time go slow until you really get to know your machine. SAFETY FIRST. I cannot stress that enough. I have over 35 years of operating heavy equipment, I know the dangers that can happen and how to avoid them. You must be careful we need you around.
Stay warm be safe…
You need to scrape all the top soil off that road down to the clay with the Dozer and cut a ditch next to the hill for water run off or thats gona happen real often and a backhoe is a great thing to do that with ... nice buy with the Dozer tho 💯👍
Great purchase.i see you are getting some great advice on here to help you fix this dozer. I have every faith I you both,you will get it done. Nothing like a nice project to keep you ticking over during winter. ❤️❤️❤️❤️❤️❤️👏🏼👏🏼👏🏼👏🏼👏🏼
That’s a sweet old D4 cat they are really easy to get running too that’s one of the tougher version cat Dozer y’all got a good machine there.
Guys you got yourself a beauty, just make sureyou check all the oil brakes ,engin, hydraulics, ect cheers Robert
Hey guys!! Knock down where you want to grade going forwards. Don’t dig. Do your actual grading backwards.
Injectors and seals are shot it appears.. The white smoke is a combination of sunburned fuel and exhaust. They can be rebuilt. O ring kits per injector are a bit pricey though. Pressure check the entire fuel system since diesel has to have no air in system for start up. It’s a shame you guys weren’t closer I have tons of parts and guys I could send to fix you up!
Gad, why did you decide to practice on that hill???? Glad you made it and are ok. Your guardian angel was with you on that day❤
Greg & Katie your best move right from the get go, is to locate an older retired Cat mechanic thats not to greedy. I have a cat dozer D4 7U exactly like yours a 1950 year model. Get an owners manual & service manual. Get a retired mechanic thats willing to to show you how to get your dozer to start dependably, show you how to service your dozer. Expect to have put some money into dozer on a regular basis. UA-camr Northwest Hillbilly posted a whole series on rebuilding his dozer which is just like yours. Get a dozer mechanic that you can trust, that will get you pointed in right direction on getting dozer to run & start reliably, & where you should start on repairs, that dozer needs repairs right now. Maby get a few operating lessons for operating dozer, so you dont damage it, which can happen quick. That dozer can do a lot for you, but your gonna have to feed it some Franklins, Grants, & Jacksons. Good luck, welcome to CAT world
At 81 now I can remember my uncles dozer but don't remember the model at 12 I was using it for irrigation and canal maintenance. Happy trails.
Hi both, I would suggest watching C & C Equipment,Clint is about the most knowledgeable person to see stripping heavy equipment down and repairing everything imaginable and you will see all the answers to every thing that is wrong, he buys old and broken down machines and returns them to as new condition and sells them on for much less than new one of the best vloggers on you tube.Regards Jack.
The exhaust pipe from the pony motor may run through the intake manifold, which preheats the air and aids with cold weather starting.
Ah, the year I was born 1954 have fun you two.🍀🍀🍀🍀🍀🍀🍀
The bulldozer is such a great addition to the homestead certainly will get thing's done around there once cleaned up & its issues are fixed .congratulation's. 👍 Way to go Katie. Was interesting watching Greg fill in the washout area great work Greg. Awesome video, shall be looking forward to your next up. Ontario, Canada.
Now that's a snow shovel .
Let's here for the little channel that could 👏🤞🙏👍
This is an excellent acquisition!!!! You have several knowledgeable subscribers that have already provided valuable advice. Combine that with internet research over the winter and you should be able to figure out what Bertha needs. Thats my suggestion for a name :)
I think you need to call it dragonfly because it drags up one side of the hill and flies down the other 17:30
That’s great! We enjoy watching your videos. Y’all are hard working couple!
looks like some good dirt to grow stuff it probably has sand in it and not a lot of big rocks in it except those round stones that were probably in an old river bottom that million years ago were tumbled in as big creek or river that has now change coarse and shifted
So I don't know for sure, but; If that blade leaks down and looses it's pressure such that it's hanging from the come along and strap I wouldn't get my feet, or any part of myself, under it at any time. Maybe you've checked it out and if the blade is up and it's tied off it won't drop if the strap breaks. That has to be a lot of weight on that strap if it's lost all pressure.
I would set the blade straight on it and take the angle out of it. It will be a lot easier to control because with the blade angled like that it will try to steer the front end of the dozer.
For God sakes don’t ever let it run out off fuel. If you do it’s a nightmare to restart. Do your Utube research and ask the neighbors for any “good advise” you can get. Your doing a good job with the tractor on that dangerous road.
O NO HE IS DANGERS ENOUGH ON THE TRACTOR NOW ON A DOZER PRAYERS TO YOU SWEET LADY
Beast of a machine, hang on tight ❤, congratulations 🎉
I've never seen a piece of heavy machinery compression started before. Makes sense that you could but never thought about it before. Put some maintenance into "Airplane" and she'll be right as rain. Before you know it, you'll be flattening that mountain top. Have fun, be safe and thanks for sharing.
I worked for CAT for 30+ years, making the hydraulics. I hope you guys realize that, while every piece of CAT equipment is the best of its class, CAT equipment is extremely expensive to maintain. At least you'll be able to replacement parts. CAT is great at supplying parts for old machines!
Those nice rounded rocks you are pushing are river rock. Makes you wonder a little? Library might have or can get operators and Maintance manuals.
Ambition Strikes had a track tension issue, you might watch that episode just because.
Left hand pulls steering...right runs blade! Never use 2 hands on the steering. One at a time only.
When cutting into a side hill like your doing you would typicaly have the blade angled the other way, pushing material out over the edge. This keeps the machine tighter to the high side and away from the edge.
I had no idea one could bump-start a bulldozer. That was hysterical! PLEASE do something about a seatbelt in it, though. No one wants a bulldozer to roll over them. I'm looking forward to seeing the repair video for the pony motor! 🙂
A little starting fluid does great when trying to fire one up. I had a dozer and believe me when I say baby the fool out of it, it is way more fragile than you would think. It is super strong but don't make a running start at a huge stump or rock and hit it trying to jar it loose. I did that and it tore the bull gear out and they are not cheap.
Nice video. When pushing with the tractor i noticed how fast you were going. Go to low range and if you cant push it then take a smaller amount. Most of the time i run in medium range low with my 35 hp kubota. When it gets tough i go to low range low gear and it will push just about anything. Is your rear tires filled with fluid? If not I suggest you get them filed. I have R4 tires on mine no chains and plow my brothers steep driveway with no problems. Have a wonderful week
if you have not been around heavy equipment before, never get under a blade ,loader dump bed, without some kind of safety in place! hydraulics can fail at anytime, you will not have time to get out of the way! operating a dozer is more than dropping the blade and go. be patient while learning to operate the machine,it takes time to learn the tricks of a dozer,
Fix the starter. You can tear more stuff up pull starting it that you can fix. The track pins and bushings appear to be worn out. If a starter can be swapped for the pony motor it will be money well spent. Have fun.
I'm 14 years older than your new toy and I'm still going! Good luck. Well, I hobble around too.
Perfect size for small property you can move it easy with a tow truck . I bought a d7 required a lowboy haul 35 miles $500 per move 40 years ago . A towtruck in those days was $75+-
It was $500 to move it here
be sure to put a can over the exhaust to stop water getting into the engine when parked
