At idle speed my TO-35 has oil pressure of about 16lbs and at operating rpm's it has about 23 lbs. Since the tractor has been converted to an alternator I don't know what RPM I am running at but it doesn't sound wrapped out. My question is, is this okay or should I go in an adjust the oil pump? Thanks in advance

Todd that sounds like excellent pressure, if your gauge is correct. The H. Ferguson tractors pressure relief valve is set at 30psi. I know a former H. Ferguson dealer/mechanic that says if the factory gauge registers any pressure at idle not to be concerned, and anywhere in the normal zone at working rpm is fine.

Interesting reading these oil pressure posts. My tractor registers 60-85psi with an SW gauge that's not factory. I just figured it's wrong.

To high of oil presure is not good too. Oil need to go by the bearing at a pre determined speed to pick up heat caused by friction. To low it gets hot to high the bearings arn't allowed to transfer the heat. You may need to adjust the bypass valve in the oil pump. Check your gauge first and see if it is correct. Mark H.
