Re: 440 vs 1010 Finals

Internals are different, some other differences, but I BELIEVE they will work. If you have a diesel crawler, gear ratio will be different.

Re: MC grinding noise

You can't really "see" the front bearing enough from the top to get a good idea of condition. A hardened roller in a bearing never smooths out. Run it and the bearing will fail, or whatever else is feeling rough will fail.

Re: '68 350B right side final drive removal

You do not just arbitrarily add or remove shims, you need to measure the freeplay in the shaft, and adjust for proper preload.

Re: 420c reverser through the motions

Not unusual, the clutch might be dragging just enough to keep it spinning. Make sure you don't have excess freeplay in the clutch pedal. Can also be the pilot bearing going bad or already bad and spinning the input shaft.

Re: '68 350B right side final drive removal

Not positive, but I think you might be able to get by just taking off the cylinder bracket.

Re: Oil on my steering clutchs

Normally keep all the parts on hand, I think I have a parts manual on hand too.

Re: jd420 pics

Not the most fun piece to remove, they are usually kind of rusted in place. You will have to pull the rear cover gasket to hold the ring gear on reassembly, so I always remove it, and try and tap on the quill from the inside out.

Re: Oil on my steering clutchs

Either the pinion shaft in the final drive or the carrier seal in the rear end. Oil can not be cleaned from clutch discs, they must be replaced.

Re: 430C 3 point

THey are tapped 5/8" NC, clean the threads out, screw a short bolt in, drive them out with a long punch from the outside in, or use a hollow ram porta power.

Re: MC grinding noise

I would pull the trans top cover first and see if you see or can feel any other bad bearings or gears. If so, only way to fix is complete tear down til you only have the trans case left, then rebuild the trans.
