- Getting an old d7f running that was written off due to a bad torque converter leak that has been sitting for ten years and had parts robbed off of it.wlrfixinit@gmail.com
Thanks for the viewers who give me a thumbs up . I really appreciate it.
You are by far one of the best mechanic around the world i knew keep up your great work man i love your Videos 👍👍👍
western truck and tractor repair have another one then!
👍👍👍 maybe they said no more to it.
I appreciate that you can take the time making these videos why'll running a business thanks mate 👍🇦🇺
You do awesome Vids, stay safe with all the fires around.
When I heard your laughter when the Cat fired up you should have seen my smile. I know that feeling so well when old Iron fires right up after years of hubernation.
Rewatching this video. Hard to believe it was three already. I appreciate your videos. Thank you 🇨🇦
When a fella has hands that look like mine and gets straight to the point I like it
Hey dude! My late father was a bulldozer operator before. Way back mid 1960's to 1st quarter of 1980's. I used to go with him during school vacation. There's a lot of good memories for me. it was good experience fun and exciting. There was a time I'm the one driving myself a bulldozer.
Hello. Warren. I really like the sound of the 7 F. Your right people give up on stuff way to easy. It is a throw away attitude, no good. Keep on keeping on. R G the first here enjoying all you vids! Thank you, sure helpls me get threw a lot of long nights and days. I am totally blind but use to help my grandpa in his heavy duty shop in WV. I got the job of parts cleaner, and steaming mud off the cats to make things easier to get to the bolts. It was a really dirty job but I loved it. I am 63 years old now. I sure miss my grandpa he was a great guy, and he was the best cat man I ever met, you remind me of him. Your way of essesing problems and the way you tackle a problem, is just what my grandpa would do.
Thank you very much Rick. Take care of yourself.
My late uncle was a dozer mechanic, & he went to every auction he could. He once told me you paid a lot of extra for the Cat name, but it was worth every penny. Most folks said he was the best around. This video reaffirms that for me. Fired right up.
Another great video Warren. In the UK there are not many youngsters want to do this type of work, they want an easy life . The field mechanics are a special breed . I have been doing a similar job for 45 years, and also do it as a hobby . My advise would be to make as much money as you can as your body will give up over the years and you will find it harder to carry out tasks . Take care mate
I appreciate you sharing your day with us, Warren! Keep up the good work.
Thanks Grant.
Nice one Sir,good to see a man who knows and appreciates Cats.Enjoyed your joy when she came to life. from U.K.
I am sat here in a cold and very wet North Yorkshire (England) and I just wanted to say how much I enjoy watching your videos, and to thank you for your time and effort in filming, editing and uploading them. Keep up the great work - it's fantastic to see such wonderful old pieces of heavy plant being brought back to life.
The knowledge and professionalism you share in your videos are second to none. The school of Warren is better than any college you could attend. And your enthusiasm for your work makes these videos fun to watch. Please keep up the great work and great videos!!!
I sure appreciate you taking the time to film this. Thank you very much
Got to love those old cats started up and moved like you gust shut her down yesterday. Meanwhile it's been sitting for 10 years blows me away every time I see videos like this. Engine wasn't even warmed up and it moved with no problem.That tree is going to miss the old cat been leaning on it for a few years by the looks of it...
Your knowledge is priceless! Thanks for taking the extra time to make these great videos!
Another great old Cat saved and put back into service. Thanks for the video and driving tour.
Hasn't run for 10 plus years, but you made it look as though it was running yesterday. Top job warren.
I was surprised how easy this one fired up, it's got a pretty tight fuel system.
I like the way you take us along in real time hearing you work through the thought process of troubleshooting, rather than over dub
bling it later. I appreciate that it’s an added annoyance having the camera on your head
You gotta love old machines like that, it's such a tank the old bastard starts up like it's been sitting for 8 days, not since 2008 !
Great video Warren. Love it when you get a piece of equipment going after many years sitting. What a whisperer you are! Thanks much.
No, thank you. Take care.
Agree is awesome to see. I wonder how much of the "modern" equipment / machinery would fire up just like that after so long sitting? I suspect very little.
@@westerntruckandtractorrepa1353 dear: warren cat d7g. dozer blade is suddenly down in action diagnosis please
I'm a retired Caterpillar design engineer. I cut my teeth on the old 200 series excavator. I designed the 235 final drive, pump drive and swing drive back when they was introduced in the early 70's. Before life at Cat I worked road construction, mostly interstate highways, in the 60's. Loved the old Cat D8's and D9's. We moved dirts with D9's and scrapers and of course fine grading with motor graders. Cat caught my attention because we always seemed to have Cat's working when the green stuff was broke down. Loved your video and will be watching for more.
Who designed the 215 haha if you know smack them for me hahaha
@@jarrodclarke6747 The 215 was not designed by the 200 series engineers. It was a joint venture deal with a small German company Eder.
Thanks for taking us along for the start-up! Really appreciate it!
I love to see you work on the old school tractors. No electronics to mess with, no asking the computer for permission to do something. Keep up the good work. Already hit the subscribe button.
I've enjoyed you bringing the D7 back to life. It is a great tool to work with and all tools need to be taken good care of.
I love that you had the patience to prime the fuel AFTER you had good 24v cranking. Most other lesser mechanics would just sit on the starter and flatten the batteries before the fuel got through!
I like the old style dozer. Starting right up after sitting so long just shows how well the old stuff was made. Sounded really good. :>)
I think it probably was cleaned up and first started prior to this video...
It’s Jurassic iron been there done that you might get a couple years out of it then it’s good money after bad
Another great video Warren. Those 81 people who disliked this all have a serious problem and need to see someone about it !!! Oh and greetings from the UK.
Not exactly sure how I found your channel but I am enjoying it. I am a retired Heavy Equipment Field Mechanic that worked for the State of California. I am envious on the amount of time you actually get to spin wrenches. This is what I envisioned when I became a mechanic not the paperwork and politics of being a state mechanic and having to beg for hours to get $500 for parts to repair equipment.
I was a mechanic on submarines in the Navy, same thing they wouldn't let the crew do anything, they waited till return to Port and the ship yard did the work. We did a lot of meaningless paperwork as well. That 6 years in the usn told me That I didn't want to work for the government .
Great video! I love these where you get something abandoned running again! It shows how well made this older equipment eas made. Will probably still work circles around newer stuff with all the electronics and sensors they have on them now. sure a lot easier to work on and get to stuff. Thanks again Warren!
Love seeing that old stuff come back to life! Awesome work!
Its a great feeling to work on those old machines and making them live again. I have a 12F grader that needs to have the clutch brake looked at. Never seen one on the inside guess that will be learning time this winter. Hard to find a mechanic that knows how on those old machines. Thumbs up bud.
Warren, thank you for making these videos, I have never worked with heavy plant machinery (although I do work on London underground trains) but I happened to watch one of your videos and was hooked by your content and your no-nonsense approach to getting the job done (whatever way to get the correct result). So again, many thanks from the UK.
Damn not a surprise the old girl will run and move. Even after 11 years.that is a Cat for you.great to see it move again.
I can feel the excitement when you get these old machines fired up and driving.
If the "Duo-Cone" pinion seals between the transmission and final drives have failed, transmission oil would leak under pressure into the ham cases and out the vents. The leak would manifest from the final drive vent down the back of the ham case to the ground, and could easily go unnoticed because of the grime and dirt on the undercarriage. I ran 94N D7F's, 48A D7E's, and 46A D8's for Weyerhaeuser out of Klamath Falls in the '80's. I surveyed and built miles of logging roads with a 94N D7F just like yours, but with a tilting 12-foot Balderson U-dozer and hydraulic Esco boom with a 96-inch Esco grapple for skidding right-of-way trees. When you lit a fire in that old girl, the exhaust note made me cry. God, I miss those days and those machines!
That "Old Girl" is a Keeper!! You are correct. People see a leak and think, "It's Done", and park it. Good for men like you and I that can get a "slice" of that Heavy Machine "Pie". That Old Girl runs like a champ!
Hell yeah. Good video and nice work. I love seeing old machines instead of new emission related junk equipment
love this old equipment . Seems such a shame people just give up. 20K just to throw is away. We should be so luck to have 20K to throw away like that. Thanks for the Video' s Warren have learnt a lot from you.
@Thomas Hood agreed it kicked alot of people in the nuts in different industries.
Really enjoy your videos. I believe you are the first person I have ever watched who just lets the cameras roll and gives us exactly your perspective and thoughts as you troubleshoot your way through ton after ton of diesel iron. Keep up the great and hard work!
Good to see the old girl running. I think stuff gets parked because the owners aren’t the operators. Guy running it probably said it’s puking oil and won’t move. Probably never checked the oil till it quit moving
Love old CAT iron, tough as they come & go forever with maintenance , cash & care...keep yr videos coming, they are brilliant.
Those cats are pretty tough machines. After sitting around for year, relatively little was needed to get it rolling again. Great job.
Wish I could give more than one thumbs up. Hard working with integrity is a difficult combination to find now a days. The knowledge base is amazing and you retain it; me I have books to retain it. Thank you for sharing that knowledge.
Thank you very much.
I am impressed with start up and your candid commentary, being from the Uk I love your accent to. Well done and keep producing these great videos. Thank you.
Just shaking my head thinking about why that D7 was parked. Something so incredible about seeing an old engine like that come back to life after 11+ years of hibernation. Great video 👍
Thanks for this. It took my back to when as a college kid in the early 1960s I worked with my father for Union Engineering in Ventura, California. There was a time when I worked as a swamper for a catskinner named Elgin Carter. It reminded me of the early morning when he'd check out a D8 before he started it. No electric starter. The starter was a gasoline engine that you had to hand crank to start. In the winter, you needed a spray can of ether to prime everything.
I enjoy your videos, you go where your ask, assess the problem, go right to work.You are smart the way you use your service truck, work out of it at the shop and in the field.
i would say if you restore those machines more often you probably the best man for the job on youtube i know for sure you are one of the best man
Thanks
Always enjoy bringing old machinery back to life, also enjoy touring old salvage yards as well
Nice job rescuing it! I love the sound of that 3306. A little over a year ago, I helped rescue an Allis Chalmers 655 track loader that was in a similar situation...the engine had been rebuilt 10 years before but they wrecked the torque converter seal putting the engine back in, so it leaked out ATF as quickly as they could pour it in. I helped a friend get it started, and we got it running and driving (barely) long enough to load it on his trailer.
Love to see these old machines fire up after sitting so long. Love your videos.
Operated a D7E in 74. My mentor operated a D7F. Completely different machines. You could put your fist in the bull pin hole. Worked in sand (Virginia Beach). Wore a set of sprockets to the point I had to be pulled or pushed out of the pit and onto the truck for transport.
Always a pleasure watching your vids! This one was extra sweet, getting that old Cat roaring again.
Dad: you think Warren will get that old D7 running?
Son: c’mon Dad, it’s Warren, if it doesn’t start right away give him 5 more minutes.
Thank you Warren, always time well spent watching you work your magic 💪👍
You are a workaholic and we love you for your passion and dedication to doing this for a living. 💪💪💪❤
Thanks for the awesome videos Warren, you remind me of my grandfather who use to drag me around as a kid and fix abandoned machinery. I learnt so much from him and its great to watch you do your work....his stubbornness never faded and never let a problem beat him hahaha
Awesome to see the old Girls come back to life , i still run a couple old D8H46A 's 1960 and a 64 Great machines
A great mechanic you are for sure watch most of your vids and learned a think or too Keep up the great work and vids Cheers
Watching fella's like you on UA-cam - all American, it has to be said - makes me realize that l just missed my true calling in life. Not just because of the greener grass other side of the hill but for the job satisfaction and independence, just so long as the customer pays up, of course. Bundle-up warm, stay happy. Good on yer.
This was one heck of a good video. How in the world you can work, and still operate the camera is amazing. That D-7 is a real find, and would not take too much work to make it a good, reliable piece of equipment.
Warren's such a good mechanic he can literally do it one handed.
Hey Warren,im glad i just saw you post this, i love your videos man youre doing an amazing job i run a small dairy farm with my dad and i love using the knowledge youve taught me on the farm
Thank you very much for your compliment.
Absolutely ready enjoy when you are working with old cat . Love that sound when they start up. I personally prefer the older cat stuff. Thanks for sharing.
Thanks for the trouble you go thru making these videos, Ive learned a lot from you. Good to know there are folks out there that still use you tube as a knowledge sharing media. Thanks again,
Hey Warren, thank you for your effort in showing your work. It’s a hard enough job for most of us without dragging us along with you. Just a comment regarding the oil leak. Just to the right side of that suspected pinion leak, there was a oil supply or oil return pipe with a typical hose with hose clamps that really appeared to be leaking profusely. A very typical Cat product leak issue. Hoses shrink and go hard and clamps are no longer tight. Just a thought. Thanks for all your vids. You are a extremely knowledgeable Tech.
Loved the ride on the Cat. Great video, Warren. Someone is getting that Cat for a great deal. And you are the guy to make it happen. Thanks for a great Sunday morning!
Facinating... I used to be a time served car mechanic back in my youth but always fancied myself on the heavier stuff, esp the Cat... would just love to have a go driving a D7; it's on my bucket list :) A local farmer (in the UK) where I go metal detecting has a big old crawler parked up on his farm... when this corona shite has gone away I may try and arm twist him to let me have go on it ^
I enjoy most of your videos, but really enjoy the ones where you bring back old iron. The new stuff seems like it's always electronics or sensors. The old stuff is mechanical, whether it's a bearing, a seal, or a gear, etc. it seems more interesting than reading a computer screen to diagnose problems--and you are capable of BOTH! Great job Warren!!
Every video is like being in the class room. Thank you for all your videos.
You said people give up on stuff too easy and I have to agree with that. I bought an 05 Jeep Wrangler TJ Rubicon a few years ago and have had to replace many parts and am now rebuilding to front and rear differentials. Everyone keeps telling me to get rid of it but I feel like working on a Jeep just comes with the territory. Eventually it’ll all be new.
Am jealous and do envy the space weather blue sky's and ! all the open but dusty country , but especially all those abandoned vehicles waiting to be fixed up as you passed by whilst testing that old dear for lower end mystical leaks!!! ,, good luck.👍.
Warren your thumbnail picture of the d7 looks like a very finely done watercolor painting. Be very proud of the eye you have for beauty as that is beautiful.
Love the old cat videos....they have a sound about them. Thanks Warren
! Just another in the field with Warren...... you make it look easy..... I know better... have a good weekend!
You too. Take care.
Love the will it starts.
That was the best one ever, so professionally done and quik,
The hydraulic tank didn't look good all rusty.
Alternator must be shot 0 amps.
She started pretty good, plenty of black cat ghosts come out of the exhaust.😀.
Running so clean.
Not so good on the right steering lever
Great job,
Ya can’t beat the old cat’s. Love the sound and the looks. Thanks buddy keep up the good work.
Hi Warren, as other, I used to go around with my father fixing these machines in Nigeria, bush repairs most of the time, brings back many memories, luvin the vids as usual.
That’s incredible. 11 years of sitting. All I could think about was the condition of the lubricants and cooling system fluid.
I was saying, NO, don’t start or run it until those fluids are flushed out. The cylinder walls were dry just to be introduced to 11 plus year old oil.
Still, I enjoyed the video.
Always plenty of variety Warren love those old Cats 👍🇦🇺🚜
As you’re moving her around that field I’m thinking how long it’s been since I sat in a seat with that view. I remember though like it was yesterday, even though it was 1980 in Germany at the Fulda Gap, cutting a 500 foot long antitank ditch… Moving earth like it was butter, she’s a beast that’s for sure! So many good times while in the army playing with heavy junk, especially overseas. 😉 Great job, thanks for taking us along, 👍🏼👍🏼 from this guy!
Remember in bed before getting up to go to grade school the Caterpillar man would start a little motor run it for a while
and it would start the great big motor enjoyed watching again take care Warren
I use to work for an excavating company, he has 2 Allis Chalmers HD 16'S. The older one has motor oil going into the torque converter. They've took it apart a few times & can't figure out why it's doing that. They've put new rear main seal in it every time, we checked the mains to check for slop, changed the oil pan gasket of course. They don't know what the problem is. I personally think it's the torque converter itself. But what do I know, I just worked there.
Love the video . They have changed a lot over the years except weight of a 8d. 3306 is one they should never have quit making.
Always like, and I appreciate the time and trouble you go to to make these videos, I'm always looking to learn something or a new way to get around a problem
Thank you.
Before going any further check the crankcase oil level while the machine is running and see if it is over filled with all that use. If the scavenge pump has failed the torque divider will be overfilling and transmission pump pushing oil out all the seals through the TD. Also the transmission will become under filled. I just figured this out on my d6c. I wasted $500 on fluids and drained 9 gallons from torque divider housing when it should only have 1.5'ish. That's an easy fix too.
Always enjoy rewatching this one.
I love your detailed videos. I don't have the skills for this work but love to watch others do it. Love old CAT's too.
Thanks for the 24-volt battery lesson!! that Cat started up pretty fast for sitting for awhile!!
Warren you make it look easy, thanks for sharing again.
Im a little late but I think this is the coolest shit!!! Love it when u bring the old stuff back to life!!!
u are one of a few that actually get dirt on his hands on u tube love it keep it up...
You are doing a great job with your channel ,I like the resortration of equipment which others have written off ,and your determination to see a job through to the end ,and your straight talking ,as in the problem child video.
Who else was all WOOHOO when that D7 turned over? Can't wait to see if its only that seal. If so,... I mean wow...left it there for bad seal...I wanna see this fix, Warren! I hope you can sell that other one for the owner. Maybe even get DEPOSIT if they want the undercarriage work done.
Proper old school field mechanic, obviously knows his stuff and a great video to listen to. Will definitely be following the progress if more video`s are made.
Thanks Warren, nice to see a hopeful case !
Thumbs up just because you slung that battery around like it was nothing.
I was thinking the exact same thing! 140lbs pick up like nothing.
Yeah i think youd win an arm wrestling match
Hey Warren. First want to tell you that I think you are one hell of a mechanic. I love to watch your videos.
I think the reason why you were having a hard time getting it in gear is because Cat transmissions have some type of safety valve in them that has to get oil pressure before you can pull it back into gear.
I know the old 955L's were that way and I would guess all old Cat stuff is the same.
Again I appreciate you making these videos and keep up the good work.
Thank you for all the good videos sir.
Used to operate these in Australia retired now looks like you got a good machine there maybe what was leaking seal might have hardened over time and settled down when you get the blade on and work it some it could reacure until then its looking ok ! Happy days ahead ! Cheers from down under
Another fascinating find by Warren!!! Great job Bud! Always impressive listening to your stories of experience (and how lame some of the things you get called out for can be.) But, it all helps as Jackson Browne said, in the "struggle for the legal tender".
I like your can do attitude, I worked on a lot of cat iron . Mostly cat 922 loaders . I’m 52 and moan and groan like you . It will wear you out ? but loved every minute of it . People are lazy now a days . Thank you sir for the great video.
what a great machine and what great mechanical skill. looks like a miracle to my unskilled mind. thanks.
