John Deere A Oil Pump, Fan Shaft, and Clutch

Next the fan shaft pinon race and bearings came to pieces this summer while I was running the tractor in the field. I stopped the tractor right then and pulled it to the barn. I replaced all the bearings and races in the governer as well as the pinon race and bearing. The fan shaft pinon bevel gear had a little damage from the race and bearing coming apart in the field. The gear had some nics on a few of the teeth not real bad, so I put the gear back on. Now when the tractor is running the gear is making a whinning noise. Is this because the teeth are damaged or could it be that the gear is to far in mesh with the governer gear causing the whinning noise?

Last of all the clucth is making a loud noise as well. I've haved that clucth apart 5 times and I still can't figure out why it's making so much noise. It's only when the clucth's engaged. The bearing in the clutch looks good as far as I can tell. But it might be worn out. Any Ideas why the clutch is making such a fuss?

Any help with these three things would be greatly appericated. Maybe I didn't ask to many questions.

Have you tried playing with the oil pressure adjustment ? On the RH side under the belt pulley area there is a pipe plug. Take it out and there should be an adjustment screw right there. I'd try screwing it in some to boost the pressure and maybe even out some too incase something got lodged in it.

I adjusted the oil pressure just like you have talked about and it will make the pressure go up, but as soon as the oil gets hot it goes back to low. I will check the filter head. Thanks for the help.

I had a late B that lost oil pressure not long after an overhaul it had a bad relief spring,but those models are on the outside and easy to get at. Lucky I didn't ruin the engine.

The clutch doesn't change noise in different gears, its the same in all gears. When under a load it probaly does get worse.

Thanks,
