I ain't getting any deals or anything from the places I'm buying parts, but here are the companies I've gotten parts from so far. I'm just glad there are still guys around supplying parts to keep us all going! General Gear: www.tpaktopc.net/d4strcltch.htm Big Iron Parts: www.bigironpartsllc.com/

I used to be a Cat mech/training instructor. I was trained in the Peoria schools, and at the end of every week of training we were able to tour various assembly lines in the factories. One of the places we visited was the pattern shop, where we were told that you could order parts for ANY machine Cat ever made, if you had the serial number. They didn't have the parts for old machines in stock, but said they had the patterns to make them. No guarantee how long it would take to get the part, or how much it would cost, but because it IS Cat, the part CAN be obtained.

For your brake linkage lids that are pitted there’s a good trick that I learned while working for a local Honda dealer to true up carburetor flanges,cylinder heads,tops of cylinders and engine cases,anywhere that is machined flat. Use emery cloth or wet/dry sandpaper in the regular full sheet size,I think they’re 9x11” sheets and glue it to a sheet of glass,the thicker the better but I’ve used as thin as 3/16”. Window panes are plentiful and easy to find. Spray the back of your sanding sheet along with your glass pane with 3m trim adhesive,wait for the glue to tack up before putting them together or they’ll take forever to bond. Cover it with a book,wait 3 to 4 hours and presto you have your own surface machine,just use some light oil and a little elbow grease. I have several of them made up from 120 to 600 grit and use them for everything from cast iron to stainless and aluminum. The brake bands you have can be washed out as long as they’re still within spec on thickness. If you have a solvent tank they work great for that, I’ve used kerosene also. Afterward soaking them in a solution of Dawn dish soap and water or Tide laundry detergent overnight takes most of the crude oil based impurities out and let em air dry. By the time you have steer clutches and finals all back together they’re good to go,just my two cents but it worked for me on more than one occasion after showing up to a job that had run down equipment. I really do dig the heck out of this channel though,keep up the great work.

I'm amazed. You are one fearless guy! Enjoy the heck out of this series

Mechanic of all mechanics.....the best in the world.

It's great you're motivated with this project, some guys get a little carried away trying to keep everything OEM or perfect in some obscure way, I like that your fixing it to use it

Just discovered you and your project. Binge watched all the d4 episodes and it’s great! I drug home a 60 year old case backhoe and am doing a “functional restoration” on it also. Keep it up, you’re doing a great job and it’s excellent viewing!

Doing great! If it makes you feel any better I bought a mini excavator that I am almost done doing a quick restoration to and had discovered that the final drive was cracked on what would be called the “spindle” on a truck, and was leaking gear oil. Dealer wouldn’t sell just that part and wanted $6,000 for a new final drive and wouldn’t warranty it unless I bought a $3,500 final drive motor with it. So did what any homeowner would do and had a machinist braze it and clean the surface back up for $400. He said it would be fine and at least if it does fail it isn’t buried deep in the machine

The dozer pushing the money bags is a great drawing and it's looking like a really great build even without any extra heavy duty lifting gear you still manage to get it done 🙂 . That winch had me on the edge of my seat , hope the guy appreciated the cable .

No need to apologize for a short video. It's your project and I will watch as you go. It takes as long as it takes!

Save some metal cans - coffee cans, large tomato juice cans, etc. - wash them and number them with a Sharpie. Keep a clip board nearby when you disassemble stuff. Jot down some notes describing what you are taking apart and cross reference the can number for bolts, nuts, washers etc. Example: Remove flywheel - Can #6 Also the clipboard notes will tell you the order of operations on a complex disassembly. You can sorta follow the notes in reverse order to reassemble the machine. Good luck.

It is a big job but in the end I think you will be very happy, those were good cats. We had one on the farm years ago, wish I had it now. Keep smilin

The best 17 minutes and some change of my week! Thoroughly enjoy your videos and content!

I really enjoy your videos. I’m an aircraft mechanic and this is a bigger project than I would ever tackle. Well done!

A parting comment. Seems that KZfaq remembers me watching "salvage workshop" and his recovery of a 1950s cat 955. They kept on putting you on my recommendations to watch list. I kept replying with "not interested" . Well they ignored my request. Yesterday I thought if I watched your one show they would leave me alone. So I watched the one show.I Well.....here I am...binge watched EVERY vid you've uploaded. You win, I'm hooked and addicted. Hope you're happy now. I know I am!!!!! Looking forward to your next upload. Thanks

Man, that is an interesting project, and you don't let anything slow you down. You're a wonderful example of tenacity!

Great project videos, Matt! I just finished binge watching the first 15 of 2,478 episodes and am looking forward to the rest of the series.

My old neighbor did the same thing to and old tractor before he died now the tractor is up in North Calif. in a tractor Museum. Glad to see that you are going to paint it do enjoy watching.

Love this series and look forward to watching a new one every week!!!

Once the black cats start coming out of the exhaust and start scratching the ground you know all the time and effort was worth it.😁 Keep up the great work, enjoying your series👍👍

When you remove the spring keepers you might have to take them off like 12 and 6 then 2 and 7 till the last 2 may need to be clamped in two places , otherwise it may bind or launch past your head your choice . A 29 LaSalle has almost same clutch with 6 disks had to make own specialty tools..

Just found your channel and this rebuilt. Awesome! Greetings from 🇫🇮

I don't need a Bulldozer but watching your progress has me trying to invent a need for one. Thank you for entertainment.

There are a lot of bits and pieces in this old sled. I am addicted.

Great stuff!! Really getting tore into the guts of it now, rebuilding soon!! Loving this build. Thanks for sharing.

Yeah, I would have bagged them {hardware} all during disassembly, zip locks are not that expensive and they can be used over and over. Good sign, it did roll easily. PERFECT! STRAP IT! What about brake clean? Does a great job on ground wasps too! Steam clean soon? I like the bags of money in front of the blade. The amount of D-4's being resurrected, it doesn't surprise me parts are available. Not cheap, but available. GOOD LUCK!

A nother good one Thanks Matt! Hay quit apologizin it is what it IS . We watch because we enjoy the content. Oh and your ok 😁😂😃😂 . It's going to be interesting quick. 👍👍👍👍👍👍👍👍

I really enjoy watching this project. Thank you for making this series!

I really enjoy your work

I'm guessing Ott's Friction Supply could re-line those bands for you. They are hard to stump with any sort of friction material replacement

Love this stuff, nothing like making what you have work.

Cool man.. your doing a great job. Parts are so cheap in the US. Australia… so expensive

Thankfully, you have videos of every step of the disassembly process.....so you might be able to identify the bolts and parts by watching them. Ziploc bags....terrific way to maintain order and assure identification. Re-installing all components in the correct orientations will be greatly facilitated by the videos too. Taking pictures along the way helps greatly. Shop/service manuals may or may not provide adequate details. That machine has LOTS of PARTS ! Have fun !!

Love the cartoon character drawing of a dozer pushing moneys thats about right!!but its a project will bring many smiles yrs away!!how many grandkids can say.my pappy or uncle rebuilt a whole dozer down to last nut n bolt.i was looking for a big?????after the engine symbol.how is the thumb?snookie pa.lovin it!!!!!

Hot wrench might help on the stuck throw out nut if you don't have 1 5/16 wrench or small chain wrench. The turning clutch nut looks like it was loosened before with a chisel & hammer. Probably a previous mech didn't have the socket either. If you insist on the relining of the brake bands clamp them square to the band on 1 end and drill two holes at that end then drill your countersink and rivet those 2 holes. Then you can clamp the bands around the drums to get the holes drilled in the right spots. Easy.

You will need to replace the clutch release collar assembly. The brass peace that is part of the clutch fulcrum. It wears out on the inside. It’s in 2 halves bolted together. Cheers

I have no doubt that Northwest Hillbilly will get the project finished. Milton Caterpillar completes these types of frame up restorations for customer in upstate New York on a regular basis. If Milton Cat can do this so can Northwest Hillbilly.

Great stuff here. Never seen the inside of one before. Fascinating

Thanks for showing the costs of this project. At times I'm wondering about that watching restoration videos. Easy way to convert lbs to kg: divide #lbs by 2 and then - 10%. In your example 2000 lbs/2=1000 - 10% = 900 kg.

A box of sandwich baggies is a great tool when disassembling machines. The larger freezer bags which are heavier are also useful. Keep assemblies together avoids a lot of frustration later on. Label them for even better results (use a paint marker so the pencil or magic marker isn't erased by the fluids you are working in.).

I hope that you have a legal title of ownership of this great machine. I hate it if someone claims ownership of your tractor after all the hard work and cost and labor that you put on this great project. God Speed my friend and be very safe and do not get hurt on the rebuilding !!! GOOD LUCK !!!

This is a great story man. I hope the YT secret helper gives your channel a massive boost so you can clean up some of those costs with a meager royalty.

most steel vendors cut up left over scrap plates into squares up to about 12x12" you can make new steering clutch adjustment covers really easy using an angle grinder and transfer punches if you don't have the plate scraps cut to size..

Ive relined a lot of those brakes on caterpillars and draglines ect. The cat band is made to caome apart so it can be removed without doing anything other than removing those cover plates. Its wasnt difficult for me to remove them and reline. Today we have epoxy glue that would work. I would glue the linings in place and then drill and counter sink and install the rivets.

I’ve ordered parts for my D4 82J series from John Parks at General Gear also, new steering clutches and brakes

HI Matt love watching your video it will be better than new but please paint it Best Wishes Southampton Hampshire UK

Enjoyment by the wrench! Thanks, Matt!

Paint is a necessity. It prevents rusting and corrosion. And besides it looks new. If you work so hard on it you should drive off in something that looks like it’s new.

Thanks for some video, nice to view the removal of the Steering Clutches. Good possible suggestion, at Harbor Fright, the have a pneumatic hydraulic long ram jack for your engine lift, its work very nice and great with lowering, go check them out. My friend uses it all the time, pull race car engine out or other heavy items

I love the videos. I'm amazed at your ambition and energy!

3:09 The last guy who worked on that was not a big fan of tightening bolts!

Deja vous mid-70’s. I have replaced the clutch in a D4-7U. Spent many hours on the ranch plowing snow and cleaning stock reservoirs with it.

If you are doing steering clutches, pull outer flanges and change seals to final drives. Also do inner seals to trans /bevel shaft.

Slide your steering clutch drums off of the clutch, check for wear on the internal grooves, then pull out the flanges to the final drives and replace those seals also.

Excited for the rebuild..bearded wonder!!

Thanks for the video and up date on the Cat

a note on weights - a Long Ton is 2200 lb, a Metric Ton is ... like 2207? 2208? lb. so for single digits, the two are effectively The Same

you have some heart, best of luck on this.

I am enjoying your work and your series I love the tot board for how much it is costing you for parts and such - you never see that but it is a consideration. You should add a tool column too as some of the bigger sockets will cost a bit. can't wait for the next episode

Like #854 Thanks for the video! Life is a learning curve! Hindsight is 20-15!

Looking forward to the next video!

Jesse Muller replaced steering clutches in his JD CAT... He found replacing the bands was a great choice... (255) Buying and fixing a dozer : John Deere 450 - KZfaq .. Riveting the new shoes doesn't work too well... 44:54 in the video..

I also suggest the ZipLock system get a box of bags and a Sharpie, always have handy. If you’re like me you’ll have no idea where they all go later. And take a million pix.

Cool videos man. I have tackled a lot of strange projects but I like what you have going on here. The dozer needs a name. Something feminine but also implies full figured. I would go with Bertha, Biguns, or Kitten. Cathy McCat Face works too.

great video ,keep them comming.

Locked up bolts can sometimes be loosened by heating up with a torch the part the bolt is in. Hole expands diameter and rust etc breaks down. But you'll probably need that big opened end wrench anyway???

your doing a good job hang in there

To think that I changed clutches, (steering) and other parts in these machines when they were about the best going..... like T20's and HD 5'S, other machines even I don't remember the names of... and now I wait, breath baited as you take it apart, I feel like I haven't ever seen one before. To me that is sad... I was a horrible drunk after a divorce for six years I felt sorry for myself. Now have over twenty six years sober from booze and no want to drink, I keep thinking if I hadn't been a idiot then I could of helped you on this. You are doing one fine job, nothing wrong with being a hillbilly. People get the idea that hillbillies are dumb but far from it. Ha ha ha, love the bulldozer pushing bags of cash up on the whiteboard.

Get you 5 gallons of zep purple degreaser concentrate. That stuff will eat grease paint skin and eyes if you get it on you. Awesome stuff

You probably already know this little trick but will share anyways. I (due to horrible memory) always use zip lock bags and a piece of paper to label groups of bolts . I know some guys write on the bag with a sharpie but I am frugal so like to reuse the bags as much as possible

Warning, I've seen a video of someone trying to reline those bands (may be Jese Muller) and the whole job turned into a massive nightmare. If my memory serves me right they ended up buying bands fully relined, it may be well worth your while to investigate further before you go down this path. As you can see by the engagement of your subscribers you're on a winner with this project. I wish you all the best in your endeavor, I'll say that "wrenching" is your strength. Cheers from OZ.

You should invest in a sand blast cabinet they aren’t all that expensive. A gasket cutting kit would be useful as well. It will do better with gaskets instead of RTV.

excellent progress my dude

Brother I would chock those tracks. If that beast gets rolling there's no stopping it

Dude well done ..looking forward to more great videos

If you can not get gaskets for the dozer, you can get gasket material and make your own. Squatch253 has a ton of videos on his restore of his D2 dozer, many of the videos he made gaskets.

Hi Matt, a word of advice. You may want to look into purchasing the brake bands as a complete assembly not just the linings. I watched another KZfaq do nothing but fail trying to drill and re rivet them. He ended up purchasing them complete after stuffing the linings. Please for your own sake look into this further befor purchasing linings. Cheers Stew. I hope my advice was helpful.

All the bolts are probably loose because the machine rattles like crazy and split lock washers actually make a bolted joint worse. You're better off replacing them with flat washers and loctite on reassembly

Camping with the fam is important stuff. Don't apologize.

Divide pounds in half Then subtract 10 percent Works on reverse too

Like your drawing skills... dozer, money bags, you. lol

Matt. It's your money and your machine to do as you please, BUT BUT BUT Re-padding those brake straps I would NOT do. If they don't hold we will be watching you tear it down again. I would buy the new brake straps regardless of the price, but it's your money. My 2 cents. GL

get ready breaks.is almost impossible to add just friction pads. was 1-2 videos here that try hard and at the end they get all as set and was not so much more expencive

When you steam clean any of the original caterpillar parts that were yellow, I hope you will repaint those parts.

Going good looks like Matt!

I recall that in one of your earlier videos you had to purchase a large socket to remove one of the nuts. Should these type of special tools appear on your expenses chart? Love what you’re doing. Can’t wait for the next installment.

Yay, I’m watching this later :o) Those clutch drums are a job to get off the tapers. Has to be the right pulling bolts to screw in and some force. I don’t think they have to be pushed back on, just torqued up? I have proper old pushing tool here, it looks like a ratchet with a thread through the middle.

Use never seize copper on the brake adjuster threads,ours is easier to service other wise in the rainy Willamete vally lol Red locite the clucth bolts. or they loosen and snap. The service plates suck on the machines,they let alot of moisture in.

use plastic containers to store nuts and bolts ,mark where they are from an d date ,that should help,can work in with video.

I really like following you on this overhaul I'd love to be there to help, it's gonna be a fine machine when it's all said and done, if it where me I'd replace those whole brake bands and save a lot of agrevation . Keep up the great work, can't wait till the next episode. Cheers from Jacksonville Florida 🌞

good job.

Good job love the videos

Dude you're doing great no rush take your time more better!

When rigging always short couple your setups as much as possible. Useless long lifting straps just eat up overhead clearance. Double them up or use some other arrangement to keep your lift as short as possible for better control and clearance.

Istead of using silicone use a product caled gasket elimator it will work better it looks like red jelly

Might be time for the Harbor freight gantry crane

I'll be honest, the camera @3:37 and you moving it forward but the tractor looked like it was moving back, and I'm like... I don't think that's what he said he was gonna do... augh! it's a run away! Run Matt, Run! Until I realized the camera was on the track...

Consider getting the air operated hydraulic cylinder for your hoist

You need to get your self some red diesel. And find yourself a source for when you get that thing back together and running.

Just wondering if you regret not spending more time pressure washing more of the dozer. As you uncovered things you could get to more areas to protect all of your work.
