Re: JD 350C Brake bands

Very highly unlikely that someone can reline the wet brake bands, but it's possible. Usually you don't see many rebuilds on the wet clutch crawlers, so if yours are worn, you may have other underlying issues.
Price you are seeing on bands, and the freight seem high to me.

Re: JD 420c Crawler Hydraulic System

I would GUESS that your setup would be at 1500PSI which if I am correct would explain the lack of power. Flow is another factor, you may be down on flow and pressure both.

Re: 420C Rubber Tracks?

There is a set that will work on the 440, figure about $4000 for the conversion.

Re: JD 420c Crawler Hydraulic System

Probably not enough info to give a real accurate answer, would need more info on factory or jobber hoe. But the short answer is if it is already at correct operating pressure, increasing it will just break things. If capacity is not enough, then you need a larger hoe, not more pressure.

Crawler radiator is unique to the crawler unfortunately.

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.

Yes, I have a OEM service manual on hand, do you need parts as well?
