I just installed an oil pressure gauge on my 1955 Ferguson to-35. The old one had never worked, so I've never had an oil pressure reading.
I read in the manual that the oil pump has a release valve so the pressure doesn't go much above 30psi. After a cold start, the pressure is at 30psi, but once it's been running for a while it settles in around 21psi. At idle speed, it drops to around 10psi. Is this the proper oil pressure? Thanks.
