Ok I figured it out, pulled steering cover off, went to the freeze plug on the outside of steering clutch box towards the front. Welded a 3/4 inch nut, put a ratchet on it, got plug out. After that the rod slid out after taking pin out of the arm inside, pulled the rod from the outside out. There yo...

So I looked at manual and it says nothing about that, does the expansion plug on the outside come off?

So I took the battery box out, opened up steering clutch cover. I see the brake pin shaft that goes out steering clutch where it’s leaking, i barely see the tiny seal from the outside I just don’t know how to get the pin out to charge the seal, also don’t see the bushing. Looks like only way for pin...

Jim, it was two lines swapped, I had dozer down to transmission and going back together I guess I swapped them. Dozer is 1750 psi

I saw number 15. So hard to tell but I’m guessing that’s the only seal on that side! Thank you appreciate it

Have a 76 450c I just redid, it’s leaking where the brake goes into the steering housing. I can’t find the seal anywhere on jd parts or service manual. Any ideas?

So it’s deadheading at 1750 psi, but just kills if you continue holding it

So the boss 90 where the test port coming off the pressure side is no longer on the new boss, looking in manual but don’t see another place you can test it.

76 450c with 6 way blade, just had control valve completely rebuilt, problem im having is when cylinder is either fully all the way in or all the way out the valve block starts screaming until let off. Seems like relief valve should be dumping at that point. Any ideas?

Coarse

7/16 for the next person, weird both screws holding the brake drums to the pinion for the final drive were both broken towards the ends. Guessing they take so much abuse?

What size bolt goes in the pinion shaft in the final drive of a 450c to pull it out?

Took the motor out, clutch is toast, how can i tell if i should change pressure plate also? Read manual but nothing readily mentions wear on pressure plate.

Big air impacts and pry bars lol, my real question is how do you get the brackets off without removing steering housings? They slide up and down the rear crossbar but either hit the track frame or transmission.

Have a 76 450c that I’m going through undercarriage, bought a parts dozer and swapping everything over. The two pieces that hold the mounting arms to the steering clutch housings are worn out on mine and perfect on parts dozer. I went to change them out but backing a hard time getting them out, any ...
