Finally got around to tearing down to inspect.
The big end bearings had 0.003 - 0.0035 of clearance when checked with plastigage. So they fall within spec. There is some light scoring that I can catch with my finger nail.
I pull the engine and finished teardown. The main bearings appear...
I've had the tractor for 15 years, my father-in-law had it for 20 before that. It has always been babied, oil changes yearly and kept garaged. Not sure why I have bearing wear.
Well no luck.
Dropped pan and oil pickup was perfectly clean.
Relief valve was clean. Shimmed it out the thickness of a small nylon washer.
New filter and oil.
Same 5psi @ 1000 rpm, and 15 PSI at 2500 rpm when hot.
Its my only mower, so next step is going to be look for another tractor and...

The oil pressure idiot light started staying on longer after starting so I finally hooked a gauge to see what it really was.
I have 25 PSI / 60 PSI cold engine (1000 rpm / 2200 rpm)
When up to full temperature I have 5 PSI / 15 PSI
Yeah, not good...

After I used the tiller this weekend on my YM165, I noticed hydraulic oil / trans fluid leaking from around the PTO shaft. It probably leaked about a quart overnight. I called today and ordered a new PTO oil seal. It should be here Thursday.
How do I go about installing the new oil seal? Do I...
