The brake band came off the clips of it helps anybody, guess when I was putting steering clutch back on!

Looked through whole manual many of times, I think I’ve figured it out without it. The linkage that holds the adjusting nut on the brake band is all the way down on the bottom of the pin, so when you pull up it doesn’t turn the brake linkage. At idea how to get the slack out of it? Read hundreds of ...

Now that the trans pressure is back to 160ish I cant get the right track to work. Worked fine before taking final drive off and all linkages to rebushing, with trans guage when i pull back left steering lever guage jumps about 50 p.s.i., pull right steering handle back it jumps maybe 4-5 psi. When I...

i tried using shell oil with the same spec, come to find out the drum was mislabled, put hyguard back no more problems..

450c left steering clutch is filling up and starving trans pump, any idea on common sump where it drains back into trans? Looking to see if it’s stopped up

Have a 76 450c, took it down to change final drive and now the opposite steering clutch is filling up and not draining back into transmission fast enough for it to build pressure. it is common sump and has never had this problem. so when i check trans it shows empty but left steering clutch is full ...

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?
