caterpillar D3 dozer undercarriage

[@dalebailey1844]

Hi Chris. I noticed that the upper roller was worn to the inside, a lot more than it should have been. your adjustment and mounting screws were out of adjustment. you need to pull a string line from the inside of the front idler to the inside of the sprocket and see where it hits on the new upper idler or your new upper roller will wear out and cut your chain even more than it appeared to be already. All you have to do to adjust it is loosen the bolts and pull it back out until it is in line with the chain... Have a great day.

Greetings from Australia. I have the same-ish dozer CAT D3 1975 ..Love your videos!

[@2020HotShotTruckingLLC]

I don't know anything about tracked equipment except that I want some! Lol! Having said that, with industrial equipment chains, the wear and stretching of chains is what wears sprockets. The distance between the "rollers" increases and the "rollers" ride up on the edges of the sprockets and wears them. They usually get pointy as that happens. Your sprocket wear looks different so I don't know if it's caused the same way. It's great how CAT fixed your sprockets and hopefully the sections aren't too pricy. Maybe after the D3 earns enough to pay off this repair you can afford to replace the chains. I really want a back hoe or something similar as my tractor doesn't even have a front end loader. I want to expand my pond to it's overflow area which is basically a swamp full of tree roots. Would have to dig out the black soil / roots and build a clay dam. Someday...

[@chrisward405]

It all takes time and money. I can't wait to finally use my dozer at my property.

[@frontagulus]

If you leave the carrier roller uncinched, when you refit the rails, it can find its own seat and then tighten it up

[@AlphaOne7777]

Anybody else hear him rip one at 20:05??? Lol!

Thunder ⚡️ 😂😂😂😂😂

[@Reestiboy]

Great advice on the track adjust bolts

[@linvalbonner5141]

Would like to purchase one of those for my farm in Jamaica , as long as it is running and can be used, nothing too expensive

[@_robase_]

Great video. Good luck with this jewel looking forward to seeing how this thing turns out.

[@michaelcarron3418]

It runs clean, with no rolling coal. Get a flapper for the exhaust stack, keep the rain out.

[@fredscheerle7592]

looks like the previous owner brunt the air filtrer like they use to do with the old oil bath filter mesh cartridge's!

[@andrewbrenneman9592]

If you haven't bought track chains yet, get a hold of truck & track supply. I think the place is in Indiana. They are on Dirt Perfect channel a few times.

[@chrisward405]

I'll be checking them out soon. Still haven't put chains on it yet but I'll be doing it this year. I've put maybe 10 hours on the new sprockets since I made this video

[@morgansword]

I'd say that is handy as a pocket on a shirt. I have never used those smaller dozers... that said, I would of as my 650 JD is too big for most small things needed done around the homestead. I'm seventy three so don't see me investing in much anymore... All my equipment is pre sold to a guy who worked with me for years. That has to be one fine air gun that you have as most old bolts like to stay right where they sat for years. At least you can tote your machine behind a one ton truck.. firing up my lowboy is like pulling teeth. Like me, too old to be much value left... I do believe its got over three million miles on it now. Gonna take more than a squirt of paint an some chrome to get it going even close to highway worthy anymore

[@guypatts494]

Nice video

[@briananderson1781]

I like the sprockets machined for segments, did these come from CAT?

[@chrisward405]

Yes. After seeing what was wrong with the Aftermarket sprockets I decided to go with cat sprockets

[@jerryderouin9987]

Hi Chris !!, I enjoyed your video I noticed that your base edge on your blade looks very badly worn I would advise you to rebuild this before you reinstall the cutting edge by doing this it will give your blade more support and strength for the cutting edge !!

[@frontagulus]

What was your reasoning for not putting the track guards back on? Just curious. For the sprockets, did you send your old ones to Cat and they did the work to fit the track segment ring?

[@chrisward405]

The track guards were destroyed. I will eventually make a new set myself. I sent my old sprockets to cat and they welded the new rings on for the segments

[@frontagulus]

@@chrisward405 Righto thanks. I have a D2 (the old one, not the new one) and am contemplating fitting the ring to my sprocket spokes so I can install D3 segments, since D2 rails aren't available off the shelf anymore. I'm in NY so wouldn't mind a local vendor. We have Milton Cat here although their prices for undercarriage carry a significant premium over the likes of Berco and ITR.

[@chrisward405]

When I cut my rails I realized they were 2 sa Sections of channel welded together to make the rail

[@motorgrader5]

yeah people worry about engine/transmission, they dont realize how pricey undercarriage can be

[@chrisward405]

Exactly!! This project was just shy of 10k and I still want to replace the chain's and pads

[@06sportsman]

What’s that sound at the 20:06 mark? 😂😂

[@chrisward405]

Hahahahahahah bull frog's

[@mudpuddle8805]

I dont think you mentioned where you ordered your parts from. That would be good to know. You skipped the part where Cat pushed on the seals and sprockets. Even from a distance, it would have been nice to see how it was done.

[@chrisward405]

Same tool just set up a little different. I tried recording it but it didn't take. The parts came from new York

[@Reestiboy]

My track fell off...any advice on the procedure to get it back on?

[@chrisward405]

Find the master link and split the track

[@brenttauscheck8147]

What are you doing. The mechanic didn’t want anyone thinking that was his work. A SAWZALL Are you shitting me.

[@chrisward405]

Got the job done on a budget. My equipment not yours

[@justincraig8663]

How much did Cat charge to come work at your place ?

[@chrisward405]

I think it was $125 an hour on site and $150 travel.

[@thankswillie]

we did a 1981 d3b,dont remember track frame in the way?...also had cat come out

[@chrisward405]

Yeah. They changed the design though the years. Thate why I didn't see a problem with cutting it. I've been working the dozer a little. Gonna get a video of it working dirt soon

[@thankswillie]

what year is yours...ran the hell out of it,remember the foot pedals,worn smooth,,.lol

[@chrisward405]

Mine is a 1976

Dude, You hurt my eyes cutting the rail. put it back

1976

[@zacwooten1687]

I bought one that looks similar. But can't find out what year it is

You would thank but it was made to go over seas but never left.

Nice. Mine originally came from Canada

[@pattonph1]

You should NEVER chg sprocket unless u chg undercarrige It will wear wrong. U will need new sprks when u do undercar

[@chrisward405]

Agreed. I have only used the dozer for a few days since I replaced the sprockets. New chains are expensive for my pockets but I plan on putting new chains on as soon as I can

[@pattonph1]

just be careful The sprockets will wear like the old chain and then ruin the new chain@@chrisward405
