The good, the bad, and the ugly!

The bad:
Not long after unloading the new(er) WD45, I was using my WC and noticed oil pressure seemed a litle low. Checked the oil and found plenty, so went on using it, until the oil pressure gauge went back to the 0 line. Well, seems like this is a problem, so I shut if off and pulled it over to the gargage. Last night I dropped the oil pan, and found that everything looked ok. No gear problems or problems with the screen on the sump. I am a little lost as to what the problem is? Is there anything that makes the pump work internally that could have died? Any help appreciated!
Thanks

There is a possibility that you have a cracked block. If you haven't had an experience with freezing water in the block or serious over heating it is unlikely.

As for #2 WD-45, Old gives excellent advice on the filter. A note on my desk says it is Fram 159. Several filters claim they are a replacement but they will NOT work. The right filter is stuffed with a material like cotton with a stick pushed in the middle. When you put it on the tractor, remove the stick and put the rod sticking up from the filter base into the vacated hole from the stick. If the rod is missing, you'll need to find one - don't run it without the rod as there will be no oil pressure.

Conceivably the bearings are so worn out that they can't sustain pressure after warming up. Maybe, but usually not. You might also change the oil with 20W50 motor oil. The oil might be shot.
