Track Roller Rebuild

[Jethrow]

Hello,

Anyone have experience in rebuilding a track roller?  Going through my OC3-42 and found one of the track rollers wobbles about 3/4" on the shaft, enought to hit the frame and another is froze.  Any special tools, hydraulic press or slide hammer required to remove the oil seals and bushing?

I just did a couple on my hg31, wasnt too hard, bought the kit from zimmermans-came with seals ,inner bushings, and a new shaft/circlips- pull the seals out on each side, then the big circlips on each side- press the shaft out with one of the cast bushings , the flip it and press out the other bushing. then the inner bushings can be replaced and all pressed back together, biggest thing is if the shaft wore thru the bushing into the cast bushing holder. i had one that was soo worn it ate the casting where the seal sat---that was n/g anymore. anyway, pretty easy, worst part was getting the seal out and cleaning it  all up.

Mike,

Thanks for the details.

Parts alone were going to come to $99 so I ordered new for $125.  I'm anxious to get it back on the ground, so I'll rebuild later.  I haven't checked the other side yet.

My  '55 OC3 has a front-end loader and rippers in the back.  I only use it a couple of times in the summer.  My question is this - because the oil leaks out of my track wheels, I put grease in instead.  Am I doing more harm than good?

Probably, the grease tends to hold dirt & other debris in it, turning it into grinding paste. This usually does more damage than just oiling it before each use.

If from now on you use oil instead, on a hot day the oil will probably mix with the grease, thinning it out so it flows around in there better. You can kind of visualize this happening. Not sure if the theory really works though.

If you are in "farm country"  get yourself some "corn head grease". It is better than oil or grease.

Lowspeedlife has it right.
The oil is meant to leak out a bit, as you pump it in until the seals give a bit, but if its pouring right out, you could have wear to any or all of seals, bronze bushings, cast bushings or shaft. Grease is not the remedy unless, as JS says, you can get JD Cornhead Grease.
BTW I sell the cheapest bronze bushings in the land (see following pic)
