ridding on yesterday good luck I thought a would go for it and well things escalated quickly. 4.5 hours later there's no turning back. the track frame really came off quite easily I will get the rest of the rollers off and see what I can keep and get started on welding the cracks up I guess.

 mog5858 I agree, I was able to get the muffler for the pony with a rain cap flapper on my 8T motor grader today. I agree little victories are motivating 😁

I need a little help trying to find new rollers. mine are too far gone to rebuild I think. cat number is 4F3522 for a double flange and 4f3521 for a single. I crossed them up to a new cat number of 118-1612 118-1611 and 310-4915 but they are all discontinued. so I am looking for aftermarket numbers or if a roller of a newer machine will work as long as the work I don't care if they a sealed or greasable. thanks

4F-3522 cross references to 310-4915
4F-3521 cross references to 310-4912

Check with your Cat dealer before ordering. They are listed as fitting D6N and D5R so they should be available. Parts.cat shows stock in Singapore and Queensland so if it is available to Australia it should be available in North America.

Ask for the track service guy at the dealer, he can [usually] get you a discount on undercarriage parts.

thanks for the help I will look at the new numbers I going to assume I will have to buy or build new end cap or clamps that hold the roles in place. yes, Rome that would be nice I would like to think we have a good relationship with the dealer as we do all their line boring and machine work. but there was also an 11% price hike on everything on June 1. one has just got to love inflation.

your dealer should be able to order from other dealers stock. hastings-deering have ordered parts for me from the states before. so im sure it could work the other way.

I think 🤔 I got all the parts and bearings to fix the final drive now. Only thing I got question about is the steel seal plate1A4088.
 Mine have been flipped and both sides have .030 plus groves in them. I planned on making them from round stock or plate steel then just putting them on are lapping machine at work. After checking them for hardness they come in at 60 Rockwell. Little out of reach as we don’t do any grinding or Harding . Cat wants over a 1000 each for a stamped steel pice and each side takes 2 . I found after market ones for 40.00 each . Do I make out of 40 Rockwell hard 4330 or just roles the diced that’s the after market ones are not made of cheese?  Second thing is as I was welding up the crack in the main frame I saw 4 rivets down low what kind of tag would been down there ? 6x8”

Depends on how much you plan on using the machine. Even mild steel plates would last a considerable amount of time. For a hobby machine they would be fine. If you are going to use it for farming purposes (ploughing etc) it might be different. However if your aftermarket ones are from a reliable source then they should be similar to the originals. For $40 you could buy one and test the hardness and if it is up to spec purchase the other three.
