Caterpillar D2

[@JustaFewAcresFarm]

Hey Squatch, just wanna say your attention to detail is inspiring. It gets me charged up before I head out into my shop. Thanks!

[@neilshep50]

My bet for "this nasty old rod" is: Save the ends, make a new rod to the right shape, paint it yellow. put it in a concrete mixer with a bag of rusty old bolts, tumble for 5 to 10 minutes. Leave in a bath of brine for a month till it develops a rust patina, and finish with a good soak in filthy old oil. Perfect!

[@nena4215]

Oh, I had a good laugh with your comment...Brilliant!!!

[@robj2704]

Yep. I'm starting to wonder how to best preserve the patina without encouraging further rust on the bare surfaces. Maybe a matte clearcoat final paint job would be the way to go. But I'm getting way ahead of it's current state.

[@tpniefer]

The old timers knew how to build simple designs that lasted a long time. Now we can't do anything without a computer attached to it that provides short term service with a long term mortgage to repair it. As always, great workmanship, Toby.

We missed you buddy

[@markdavich5829]

I wish you had covered the welding fitting grinding and machining. That's the 'maker' content that's part of the journey on the way to a really cool fix - Now I gotta use my imagination and that's hit and miss.

[@nathanwoods758]

No need to apologize for everyday life. Love the content as it comes.

[@robj2704]

Can't wait hear that beast really grunt when put under a load. That's where they really shine.

[@nena4215]

That new spacer you made was brilliant! I spy with my eye that your eye is almost 100%, holy cow, that injury was brutal, glad to see you totally got away with that! This series is just fascinating with all the heavy, bulky parts and the simplicity of its design for the day. Thanks so much for the episode

[@dansevern3291]

Why am I so fascinated by rebuilding a machine I doubt I'll ever see one of in person, let alone need to work on it? (Could it be that I'm just happy to see a machine that's being repaired that's actually almost 20 years older than I am?🤔) It's not like I don't have plenty to do keeping the equipment I use on the ranch running every day, but I guess seeing someone who actually thinks through the mechanics and physics of machinery is so rare to see, it just keeps me watching. Thanks for sharing.

[@tda2806]

Always a good day when when of your videos drops. You're right there is something really satisfying as those dogs engage/disengage, great work with refurbishing their corners.

[@billwms2790]

You are a great mechanic and craftsman with tooling skills unsurpassed...I hope you have a child that is as patient and creative as you...I truly hope you can pass on the interest and your ability to another generation...something that we have lost. Most interesting "class"...and learning experience. Your are a great example of a what a teacher should be. Thank you for sharing!

[@jbj27406]

Those steering clutches are so gorgeous I kind of hate to cover them up. Well, I don't hate it THAT bad. Nice work on the PTO.

[@darylmedd1168]

On heavy truck winches we use the term “negative draft” to refer to the angled cut of the dogs that causes them to pull together as torque is applied. “Search “winch dogs negative draft “ to find examples of this term being used.

[@texaslstar]

Glad you were able to get some shop time.

[@familytraditiontransportat7951]

Love it! Can't wait for the final drive rehab! She's starting to come back together

[@1crazynordlander]

I am not the one that gave you a thumbs down in case you were wondering! We chatted about this! The saddest part of your videos is the end...Great work!

[@joelaughlin2815]

Crescent wrench, channel lock pliers, vice grips, great inventions!

[@ronaldbradley9949]

Seeming you use your seal/bearing driver made me remember. How the maintenance man in the factory where I'm retired from had me make different ends as needed for him. Some were real oddball sizes. I worked in the machine shop of the factory.

[@blaircrocker9845]

Hey squatch the eye looks a lot better. Can't wait to see this thing start nice series. Saw your comment to Jonathan w you are like a Yoda of cats. Do you have any plans for a grader restoration that would be a great series.

[@aserta]

As Adam Savage said it in the show MythBusters, (paraphrased) "to make science you take notes". So, i think it's fair to say that Squatch here has taken the rebuild of a Caterpillar down to science, considering the flight-ready checklist notebook he has. :) Yet another great episode!

[@woodhonky3890]

Nice work on the dogs!

[@scrotiemcbogerballs8286]

I’ve been waiting all morning for this lol thanks for everything buddy love the channel it brings back memories of dad running and working with his old d2 thanks again for sharing everything with us god bless you and your family

[@jongraff6931]

I was starting to have withdrawals! Great video as usual!

[@bcbloc02]

Best part is now you can easily dyno the D2 once it is assembled. :-)

[@JJ-jv1gu]

Hey BigMan why do u build one of them big twin turbo sets up for him, it might wake up that yankiee rig

[@paulg3336]

2:02 "undercut" is the correct term when applied to engagement dogs. 9:57 If you cut a section of smooth plastic from a mineral water bottle and wrap it around the shaft (single layer), you can push the seal on over it and it will guide the seal lips over any edges or O ring grooves without damaging the seal lips. Once the seal is seated the plastic strip can be pulled out. You really should use thread locking compound on all exposed external threads so that the next Squatch that rebuilds this machine in 3024 ,does not have rust seized fasteners to contend with - just the radioactivity of the machine itself.

[@alankuentz4617]

😂

[@bluegrallis]

Back when I was working, we didn't have anybody in the shop that drank from a single serve plastic water bottle, so I used .005 brass shim stock. 😉

[@paulg3336]

@@bluegrallis I actually use mylar film that is used to make photocopy transparencies. It's the same material as clear bottles (PET) ,but thinner and more rigid (less plasticiser) .You can use polythene film too. With metal shim you have to be careful the edges don't cut the seal.

[@iainking4256]

Toby there you go again getting us all excited, give us time to recover from the PTO rebuild ( another brilliant rebuild there), there are some of us that need time to soak it all in. To be honest the next two things are what I have been looking forward to, as well as the rebuilding the tracks, yes it doesn’t take a lot to excite this old codger. Great work just keep it coming. Cheers from the scorched land that is currently being drowned under above twenty feet of water, we call it rain over here.

[@frritter8253]

Super video Toby! Always so very interesting.

[@cjeeper86]

He’s not frozen stiff! Thank god I was about to head north into the frozen tundra to find you under a starting engine block.

[@jenniferwhitewolf3784]

Big step of completion in the drive... now the outer components can start attaching👍👍👍. Beautiful re-work.

[@garyfeltus9801]

It's just so much fun watching al of this thing going back together. Great video.

[@dr.skipkazarian5556]

Nice engineering on the shaft rehabilitation....good eye and a ton of patience.

[@TheMetalButcher]

That fit at 17:20 is just perfect. Well done!

[@rustyreckman2892]

This PTO is so cool.

[@Ham68229]

Put a thrust bearing in that shaft instead of a washer. A washer is just going to be metal on metal and still grind down. I hope you're understanding what I'm saying. We always called them flat bearings because of their shape and design. Great video, J1113 is getting closer to be running again. Cheers :)

[@maggs131]

The shaft he used that spacer in was splined so it cant spin on the old washer or new spacer. That's all it is is a spacer so the PTO engages fully

[@Ham68229]

@@maggs131 yea, I get that, but over time, it will be metal on metal, washer's don't last long against one side spinning vs one side not and engaging. Seen it happen many times. Cheers :)

[@rickyjessome4359]

We all missed you my friend! Great content as always. Woo hoo squatch is making new tools! Looking forward to the next one.

[@darinhassett4708]

Squatch253...... squirrel moment oh yeah I hauled final drives in LOL

[@billhartl6601]

Lmao, At 6:17 you used a hammer to tighten the detent plug!! Ughhh, you gotta get a set of star sockets, lol

[@bobpaterson1845]

Another great episode 👍 an related to an earlier video about the drawbar am sure the reason the TD 6 pulled a lot flatter is because the drawbar was mounted much further forward in about the middle of the track frame where the D2 I was surprised to see bolted directly to the very back o the machine 👍👍

[@JA-ux7dd]

Great video, I really get the feel for how it was back then.

[@JD-ce4so]

Don’t stress your self out with videos. We love them but don’t kill your self with them.

[@colin8532]

YES! I don't know why, but I've really been looking forward to the final drives, can't wait!

[@douglasbranham6099]

G (grease) ASC (anti seize compound) G is made for bearings; ASC is made for fasteners. G is for fast moving, low load, low temperature (less than 400 F) bearing applications; ASC is made for fasteners, slow moving, high load, high temperature torquing applications. Grease is oil suspended in a matrix; ASC is solids in a grease carrier. G has a low film strength which is not strong enough hold against pressure from asperity contact; ASC has a high film strength. In extreme applications, the oil in grease is washed out or evaporated leaving the matrix, often soap, which allows seizure, galling and corrosion; the solids in ASC's stay to protect the mating surfaces. G gives inconsistent torquing results; ASC gives consistent and the best torquing results. Compliments of an old, over the hill, mechanical engineer.

[@MindBlowerWTF]

2:10 We just call it undercut when we talk about rally sequential gearboxes.

[@markbehr88]

I love your passion and attention to detail. Great stuff.

[@johnlanham9057]

As always ... love your content, & the quality of your workmanship. 👍🏻👍🏻

[@MC-re2ry]

Hey! It's just like the old Ronnie and the Daytonas song, "My little PTO. You're really lookin' fine. Three deuces and a . . ." What's that? Oh. Yeah. It was GTO. I knew that. Just testing. But it really is lookin' fine.

[@cassiuspuckett8789]

Missed ya, Squatch. Professional work always interferes with fun time, don't it? Another great video, Toby! Bin waiting for the final drives. I've watched other people's videos on doing the final drives. And it doesn't look easy. Till then, I'll wait with baited breath!!!!!

[@WACRE44]

Nice job thanks for your vlogs was great fun thanks

[@thomasbailey8306]

It looking good Bud.It works slick..Great Video . Thank You for sharing

[@ron827]

Love your idea of rake on the PTO dogs which should have been done at the factory but ... Lots of great measuring and planning equals, "I'm liking that."

[@JMassengill]

gravity, its the law..... Wonderful work.

[@todddebockler7786]

Reminds me of a dog clutch on a out board boat gear box

[@tmbevtfd]

The coupler dogs and the operation you did on them is called back cutting. Common work on motorcycle transmissions. Probably many others.

[@movingforward6099]

Outta all of the builds you have done this is really enjoyable for me !! Gotta love an old Cat! Cheers !

Man everything is coming together great! Can't wait to see more videos in the near future! Can't wait to see that d2 finished!👌😎👍

[@jimeditorial]

Squatch, I heard that Jim Hall used the same undercut dog technique on Chaparral race car transmissions to keep them in gear under throttle.

[@brycewiborg8095]

I like how you slipped the fact you had moved the finals in. With my attention span for a moment I thought I was listening to myself.

[@AndyFromm]

Looking good 👍

[@michaelscriffiano9267]

As always. Thank you and stay safe

[@deannajoseph]

Good Video Squatch, Thank You. Have you any concerns about movement of the gear bearing races in their housings? They seemed to seat very easily.

[@billraccio3835]

Great Video!!, always look foward to them as well as the progress on the project.

[@ryanridgely7807]

Very cool! Hang in there, man!

[@JamesJones-gk5jd]

[@clydeschwartz2167]

[@johnbarham7718]

And another fantastic video.

[@evankibbe590]

Hey Squach!! Food for thought!! Probably just me but I would of cut a 0.010 grove in that beautiful new bushing in and out . Spiral grove !! And I have been thinking about the end clearance bushing !! You could of put it in where it should of been not that where is not good!!! If you would of tapered the outside edge and cut oil groves on the edge and on the faces and a hole in the middle it would of worked !!!! But I like the way it is working !! Very good job !!! Have you ever heard of aluminum bronze bushings?? Very durable!! 😊👍👍👍👍👍👍

[@beginlivinglikeaboss]

Your little improvement on that dog clutch probably would have prevented the excessive wear of that shift fork throughout the working life of that machine

[@growingknowledge]

Great video sir, always enjoy your content and learning from you and your family. Please keep it coming. All the best.

[@ronniewalker2881]

excellent video man

[@chucktodd7329]

Here comes my Back Seat Driving: @10:36 I would have done it in a different order. I would have worked the seal over the shaft journal before mounting the lever on the bottom. Basically mount seal on shaft, load shaft into housing, then seat seal. :Grin:

[@garybaughman7099]

Thanks for another well made video with great content.
