Folks:

I overhauled the engine in my 1964 1800 C Diesel this past spring. I had a complete valve job, new rings, new sleeves, new pistons, new rod bearings, new wrist pin bushings. I did not overhaul the oil pump, though.

I have worked the tractor in our hay operation for about 15 hours and have the following issue that I need suggestions for remedying.

When cold the oil pressure is 40, within 1 minutes of running the pressure drops to about 36, after 3 minutes it is at 30, and after about 5 minutes is is down to 25. As the pressure drops a knocking increases in the engine. The sounds is almost like a sewing machine on hyper drive.

My thought is that something in the oil pump is not right and results in less oil where it needs to go.

Any suggestions?

Jim

While we're on the subject, what is the "normal" oil pressure for a 1650 when at idle?

Did ya put in main bearings? If not might be one of them spun.

A lot of guys do a "complete overhaul" and never replace the cam bearings. Over time, they get wore out and there is a huge clearance between the cam and the cam bearings. What are the condition of the cam bearings on your tractor?

It may or may not be the oil pump, you won't know until you drop the pan and take a look at it. Then you may have to rebuild it or replace it. Since you think it might be the oil pump and Larry Harsin thinks that is the problem you should take a look.

You don't want to keep running run it and ruin that overhaul you recently completed.

don't know about your tractor but I have a Mack dump truck for the last 12 years (since I bought the truck) when I first start the engine the pressure is 90, after warm up it is 30, after warm up at high idle (1700 rpm's) it's at 60psi, I don't have any noises though...sorry I can't help you
