R62 high hyd oil temp

That's similar to my hyd problem on an earlier post.

Quick heating up of the oil in the entire system means the pump has wear and internal bypassing. Could be as simple as the brass bushings in the pump need replaced.

Do things move slower than normal?

Might be able to see a tiny bit of brass in the hyd filter.

If it is hot outside, 200 might be normal operating temp? Then don't worry.

I think you have a cartridge stuck ON . Number 1 is the master coil I think. Disconnect the wire on number 1 with the engine running and see what happens.

Doc, when I take the wire off of the master solenoid which is the farthest to the right away from the machine none of the other functions of that valve stack will work. Put the wire back on and the reverser works fine head goes up and down fine auger in and out are fine. I cannot verify the real variable speed or lift because I am shelling corn. My old Ace AC mechanic seems to think it's an issue with the hydrostat. We did check both check valves on return lines going back to the reservoir. They looked to be working okay with no obstructions. I have an operator's manual and a parts book but I do not have a service manual for the charge pressure of the hydrostat. I'm at a stand still and looking for help. No help with local shops, everyone is 3 weeks out of don't even leave their shop.

While everything was cool this morning we started the combine and began checking temperatures everywhere on lines. The valve body for the variable speed real under the cab started to warm up quicker than anywhere else. We had that spool out yesterday did not find any problems. Can I back out the manual override and do any good there? All other return lines and pressure lines we're pretty consistently in the lower 90s after about 15 minutes of running but that valve was 120.

Yes

Backed out the manual override in that valve has been running for 3 hours. Gonna remove, inspect and clean valve first chance we get. Two new hoses also. The outer coating of hyd hose is peeling off, wondering if the inside of hose is coming apart.
Thanks again for the input.

That's the weird part, I'm shelling corn, so there is no couplers. I also have the single point hookup for the grain head. So lines from the variable reel speed valve, one input from pump, 2 lines going to single point,( not being used while the corn head is on) and a return line that runs from variable reel speed through the hydrostat filter, hydro and back to reservoir through a 15psi check valve. Chance of rain hear overnight, if so, the reel valve is coming off and new hoses. Curtis pushed it pretty hard in 220 corn today and no light but that is with the manual override screw in the variable speed valve backed off. 

...so your 180 bu farm is making 220 eh?
