I'm new to the tractor business and new to the forum community as well. I purchased a Mod 640 and the first thing I attempted was to get all the gauges working. Can anyone tell me where the oil pressure line connects to the engine.

Welcome and congratulations on your new tractor. The line from the oil pressure gauge connects to the block on the right side (as you're sitting on the tractor) down low and toward the rear of the block. The fitting is hidden by the hydraulic pump.

You had to know it was there to find it. Thanks a million Sean.
Now that I have the line connected my pressure gauge shows that I have 80 lbs of oil pressure. The literature I have read says the pressure should be around 40. is 80 a problem or is there something I'm missing. What regulates the oil pressure?
I really appreciate guys like you, who are out there willing to help us neophytes.

Conventional wisdom, Rick, says to get another gauge in order to check the 80 pounder. I would run it for awhile first because 80 lbs. is highly unlikely.
