d239 engine

jstpa · Jun 2, 2011

Was wondering if you guys could give me a little advice. Last fall we put an engine kit in a d 239 engine. For probably the last 20 years as this tractor warms up the oil pressure drops farther and farther till its down to just a couple of pounds. Had to have the crankshaft reground when doing the overhaul. After the overhaul our oil pressure is a little over 40 pounds. but after a couple hours work it's back to the same couple of pounds just like before. Can anybody give some direction on what to look for that would cause this. Checked the oil tonight in the field and it seems to get pretty thin. It's 15-40 same as the other tractors we run.Also we did not put cam bearings in, as they seemed to check out ok.the water temp rides just about the middle of the gauge, theres just a bar on it no numbers.Also we get no unusual noises . Any advise would be appreciated. Thanks, jstpa

Did you put an oil pump in it?Have you made sure the gauge is funtioning correctly?Does it"make oil"?If so,it may be putting diesel into the crankcase.That would mean the pump seal has failed.(Same thing happened to my 1026 last year)From your description,i doubt that is the problem.

Delta, checked the oil pimp for wear and didn't see any. No it's not making oil.As far as the gauge goes I'll try another one in it see, it would be great if it was that simple. jstpa

Cam bearings were a problem in those engines. Have seen them totally worn out on the 310 which is same design and causing very low hot oil pressure.

Hi, to much wear on camshaft bearing and balancer bushings give low oil pressure, on those engine. Bernard le mecano Quebec Canada
