No problem or question here yet, just a tip that worked for me today......

I've been going through my Oliver 1650 (mechanical and paint) and had to replace one of the bull pinion shafts, both bull pinion bearings, both thrust bearings in the differential, and one of the PTO bearings.  When I got it all put together, I thought I'd better check the pressure on the oil pump that lubricates the bull pinion shafts and the PTO.

The Oliver service manual says to braze a nipple on the end of a new oil filter, drill a hole through the filter, and put a pressure guage on it to check the pressure (should be between 8 and 14 psi).   This might have worked back 40 years ago, but today's filters (WIX) must have plastic in them.  The element inside the filter must have melted and was loose inside.  I didn't want that filter coming apart inside the rear end.   So, I sanded the paint off the end of another new filter and used JB Weld to put the nipple on the filter.  Worked great.  I just had to be careful when tighting up the guage on the nipple.   

I'm sure there are other ways to check the pump, but this worked for me.
