"Old Betsy" was the nickname given to the hand-built prototype of Caterpillar's first diesel engine model, the D9900. Assembled on June 28, 1930, in San Leandro, Calif., she was given the serial number 1A14 and was used in tests for more than 16 months before the engine was deemed ready for production in late 1931.
Awesome! I love that type of info
@@ScrappyIndustries Living in the Peoria, IL area, I am aware of a lot of CAT's history. Thanks
I've been a auto motorhead for 55 years, and now, with you, Matt, and Area Diesel Service's help and education, I am now starting to feel like a vintage diesel motorhead as well! It's nice to see guys who don't act like screaming swearing apes take problems like the normal things they are with a smile, even when disappointments happen. Thanks for the great content, and I'm eagerly awaiting the next installment on the Bay City shovel saga!
Your standing the engine up couldn't have gone any worse than your boy Mat's did.🍻
He's picking up too many of Matt's bad habits......
Who knew how valuable that tyrex crane would end up being 😂
I agree!! Didnt know I couldnt live without it
@@ScrappyIndustriesthe remote is a game changer/labor saver!
That's why I like watching your channel because it's more complex and you try to fix things right, instead of other channels that hack something just to get a video out.
Thank you i really appreciate it!
@@ScrappyIndustries as an engineer with over 50 years experience, although for me it was big ship engines, I really enjoy watching you work on this kind of engine. It gives me faith in the younger generations. 👍
Sam, I love you're attitude dude.
Despite the setbacks you never stop smiling.
You are an absolute legend 👍
check Squatch 253 for info on the pistons. When he did the engine for his 1938 D2, he went over the piston typeses. IIRC, that is OEM design, and yours are way too loose. That was the problem with the 2 piece pistons, the "ring" comes loose and you lunch the engine.
It's kind of exciting when it happens. A cloud of aluminum bits came out the exhaust while the engine knocked. Bent rod, destroyed lifters but ran enough to get the tractor loaded.
You beat me to the punch. That was a cat design, a poor one but cat none the less. I have seen one fail before, cascading catastrophic failure ensuing. Check out squatch channel, he has a lot of information on these old cat engines, might even be able to steer you in the direction of the newer updated design pistons to fix yours.
Thanks i went and checked out a couple of his videos he definitely has a lot of knowledge on the old cats!
@ScrappyIndustries oh yea he has an insane amount of knowledge about old cats I love watching his content
That 2 piece piston design is absolutely insane! I would have never in a million braincells thought that would be a factory concept!?!? Blowing my mind to think that actually worked 🤯🤯🤯🤯🤯
It is an art in itself talking to a camera and making it interesting. Keep up all the aspects of your channel
Squatch253 probably can provide most of your answers. He seems to be the king of Cats
You could mount one of those rubber squeezy horns on the top of the jib to give you an audible when you're close to the roof.
Good to see a knowledgeable person not over speeding a drill, unlike so many yt dunces wondering why drills burn out.
They were known as screw top pistons in the earlier Cat diesels and they came loose after a time. All you need to do is drill out the two dowels tighten the piston top and drill knew dowel holes and re-pin the piston top- job done
Where you dented the ceiling in your shop, write the date on the dent. Could be a talking point after there’s about 50 dents up there. Haha I😂😂😂
Love your attitude when you run into a problem and just figure our a way to fix it.
The copper ring is a sleeve shim , needed to get proper sleeve height. Those sleeve pullers are great have used one for 15 years never failed me yet . Just a thought about that grader engine if it was military they sometimes have different specs for parts to aid in repairs , I know on the MM jeep ,NTX I think, they spec hydraulic lifter instead of solid like the tractors that shared the same engine. Yes running engines with a broken crank is real , had a 4440 JD come through the shop with its crank broken at a angle at the next to last main cap , still showed oil pressure but was down on power and he drove it about 12 miles to get it here , we were shocked to say the least.
Interesting that they used copper shims to adjust cylinder liner protrusion. I wonder why Cat stopped doing that because cutting the block to adjust liner protrusion can be kind of a pain when doing an in-frame in my opinion.
With regards to engines running with a broken crank I have seen that on 5 or 6 engines including on in an Alcohol Dragster that had just set a new track record. The only reason we found it was because when we were baring the engine over in the pits backwards while leaking the engine and replacing the valve springs the engine locked up tighter than a drum. In reality it was a fortunate thing because I seriously doubt it would have survived the next pass. I also have seen tops of pistons break off and the engine continued to run albeit it had a miss but it didn’t smoke or make any strange noises.
My first “real” mechanic job was working for the local Allis-Chalmers dealership. We had a customer bring in a WD that needed an overhaul. I got the job of doing an in-frame on it. Got it done and running good and shipped it. A few weeks later the tractor was back in the shop making a horrible knocking noise coming from the bottom end. I felt terrible because I thought I could have messed up something. Turned out to be a broken crank. Our working theory was that the crank had a defect, and the increased power after the rebuild caused it to finally fail.
@@gullreefclub I work on mostly John Deere equipment and with some of the rebuild kits now days the liners are not as thick on the top so I've used up to 35 thou shims on them , also I'm no stranger to mixing up parts to get things fixed.
Kudos to the perseverance on getting a engine for the shovel, makes for a educational and entertaining sat. morning
Don't apologize for your video running out of time before you finish the work. This is a very interesting undertaking - more work is just more great entertainment for us subscribers!
Sometimes it seems that it's not about the educational experience, but rather the real world experience that You and Matt both have. The ability and willingness to try and troubleshoot, and then keep moving it forward. Always enjoy what you guys are doing.
Squatch 253 has some videos early in his d2 restoration series that show those multi piece pistons, yours are failing, also those are Cat factory pistons
With this type of content you will be at 100k very soon! Great job!
Those pistons are old OEM early 2 piece pistons. They were known to fail. Later pistons were one piece. Yeah, yours were bad ready to destroy your motor.
The struggle is Real yet Sam is still Smiling. I have full confidence you will get this sorted.
That copper ring sets your counter bore height
When we were making parts for military machines, they were kept separate from current Cat parts. Military specs were different. Example: we had gone to O rings but the military still wanted gaskets .
Always amazed at how dang smart you are .After watching any of your posts I am glad I can tie my own shoes.
I'm only here because I saw you help your mate Matt pick up some other junk for his farm, figured you were way too interested in the same junk to not be interesting.
I feel for you, just a quick engine swap, only a few minor differences. And bam, rebuilding the original engine using parts from the "good" "replacement" engine.
i love how you are always at the exact sweet spot between: "I have no f in Clue what i am doing" and "intresting this was designed in 1930 to..."
Brilliant video Sam watching from Edinburgh Scotland UK 🇬🇧 👏 👌
A little “ Simple Green” in a garden sprayer would help!
Man that's interesting never the less , can't wait for next episode Sam,
Interesting, I like the fact you were able to figure out what you can do to get one good engine out of two engines. Your knowledge of diesel engines is impressive to me and interesting to listen to. Looking forward to seeing the reassembling of the engine and getting it back into the Bay City. Thanks for the video, I appreciate the time and effort you put into the videos.
Haha, we make jobs seem simple when we vision it… then the equipment laughs in our face and and says “jokes on you “…
Well, I’ll be looking forward to the next show.
Thanks Sam
It's easy for me to say. But I'm glad you ran into so many problems, lol. I love when you rip into things and rebuild. Love all the glory in the old steel.
Just in case... Mic your crank, rod journal, measure the rods for length and journal diameter. Check the crank throw and piston length. You don't the piston skirt to hit the crank or top to hit the valve. You MAY end up swapping rods. I saw the wrist pins had clips. While it's apart and you're cleaning that way you can assemble with confidence.
Squatch253 might have some leads on parts, he’s always messing with those cat engines
That crane is worth it’s weight in gold
Just thinking the same! That lil' crane is becoming a very important item in your shop.
What a can of vipers you opened! I have no doubt that you will get it back together and running again. Made for a first class video and thanks for that.
After watching this video a few words come to mind: Recalcitrant, cantankerous, stubborn....... Liked this one much!
This is an excellent. Channel. I love watching your videos and learn so much
As you were standing the engine up, I was recalling Matt standing the Cummings up.
It still made for great viewing bro, the crane is working out well too. Safe travels. Ken.
The 4600 was a good engine. Cat wasn’t in the diesel business very long when they introduced it. I respect the effort you are making to build a good one out of what you have there. Great video.
Outstanding effort Sam, really appreciate your commentary. The "T-Rex" is certainly proving to be a valuable addition.👍
Caterpiller made those two piece pistons. I had one come apart. Amazing you didn't have the same thing happen.
So much more interesting when things don't go to plan. I love this suff!
That shovel is beautiful
Will also be interesting to see if the adjustment on the oil pickup will bring up the oil pressure.
When you buy a crane and suddenly everything you do involves the use of the crane..... a timely purchase...... cheers from a guy in New Zealand leaning on a crane......
I think Matt can sympathize with the forklift method of standing an engine up.
I would have done the roof dent too no way around it.
No apology necessary it’s all good.
Well, at least those loose piston tops would keep the lower piston cooler.
Great job!
Always interestting! Thank you Sam.
Love the never quit attitude. Wish I had a rc crane!
Awesome and outstanding.Thanks for sharing and taking us along.
Thank you for another great show! It was great.
That T-Rex has proven to be one of the best pieces of equipment you have.
Awesome Saturday Video 😊👍
Great video Sam. I look forward to the next one.
I bought one of those chineseium propane instant water heaters and connected it to my pressure washer and it works fairly well, but I'd bet if I had bought two and hooked them in parallel with 'T' fittings on the water inlet and outlet, it would have been as close to a $3k steam genni as one could get for less than a 1/4 of the price.
23:38 I'm surprised there was no gasketed access cover on the oil pan for that relief knob, or was there one that I couldn't see on the video? OK, I went back and looked closer and there was a cover.
I'm not a diesel or heavy equipment guy, but I enjoy your content and learning more about old equipment from you and Matt. I've owned a 1975 Bobcat 610 for over 35 years, so I appreciate the struggles of availability and price of parts.
Awesome job love your work
Sam, the T . erex has become one of if not the best investment you've made in a while, looks like you used it for every thing. Great buy
Love the crane remote!
Very interesting, thank you for the ride
You always have very interesting videos that i really like to watch. Thanks for sharing what you do bud.
Thanks for watching!
I'm on the "Struggle Bus" with you! It does show the ingenuity and skill of these "old school" mechanics. Good video!!
When you tip it up on its tail throw that 6 x 6 I see in the background under the flywheel housing to catch it when it drops over center. Then you can lift it back up with out all of the flopping around drama.
And ditto on the protrusion comment above. Pay attention to it. The value should be in your specifications.
Best of luck with the swaps...they can be a pain.
Great Video Sam, sorry about the roof mate, ahh well, shit happens.
Those sleeve pullers are worth their weight in gold, a great time and effort saver!
You said Matt lent them to you? they must have been on special on eBay if Matt bought them. 😄
verry much looking forward to the next installment on this rebuild.
Proper job mate.
See if Tilly's antique Crawler parts has head gaskets.
i love the way you fix i learn a lot from your channel.
HEY! Good morning Sam and thumbs UP!!
Another great video. Always learn something new watching them. Hope to have the Bay City back at Brownsville for the May show.
Very nice Video love that old cat stuff nice toolbox you got 👍👍
The joys of antique obsolete engines. I know how that goes.
Sam, an unusual, but learn as you go always seems to be the way it is, when you are fixing up old stuff. I have found many upgrades from what I thought was the same, so nothing is really that eye opening, after all the years I have been working on stuff😊
I enjoy your show. You remind me back in the day. I drop diesel creek long ago for your show ! Glad I did and never looked back...
Nice video, like the way you are using that Terex! Good luck on your restoration, and preserving American industrial heritage. A good cause.
Love it SAM keep up the inspiring work
Your Terex crane is earning it's keep
I remember watching an episode of Squatch253 who was rebuilding a D2 tractor and he mentioned that some had that type of piston which was prone to failure and was superseded.
that little crane is paying it's way already.
Sam, pay attention to your liner protrusion when you reassemble. That head gasket seals on the top of the liner. If that protrusion is out of spec, youll have future head gasket issues. I dont know what the actual spec is unfortunately
Sharing is caring when it comes to specialized tools
Great video Sam. Shows issues most folk will run into when working with old equipment. I'd like to see if the oil pressure increases now you found that bypass adjuster on the bay city engine
Super interesting !
Hey Sam, if I remember from Squatch253 channel early on how n his 5J1113 build he mentioned the early pistons were the 2 piece with the steel insert and they had the same failing point as your pistons there. The later ones were a one piece.
So you just performed exploratory surgery you are now a heart surgeon thanks again!.
Looks like he is going to do a transplant next.
Happy Saturday
REALLY enjoying the whole "Two Engines To Make One" thing.
Thanks! We’re getting there. We assembled the short block this past weekend
A guy I went to college is a direct descendant of Rudolf Diesel.
Might not have gone to plan Sam but certainly interesting From the UK
keep up the good work
Finally a break in radio silence!!!
great video good luck
Love you and your videos buddy you know what they say misery loves company
great video very interesting
Keep Smiling Sam. 🔧👍🇬🇧
Great video Sam hopefully you can make one out of the two ,a lot of work for sure but the light is at the end of the tunnel now ( you hope lol ) the terex has been great for this work take care and all the best look forward to see what happens 👍👌❤️🔧🔧🔧
Good video Scrappy! Bring Matt in to help! Matt needs to help! 😅.Thanks
Sam, I sure enjoy watching your frustration - I just wish I had your patience lol
