Well,,I decided to go ahead and tear down the engine on the TO20 as one cylinder only had 25# compression and the other three were not good to write home about. The rings were stuck on 2 of the pistons, so glad I decided to bring it down and re-ring it. Rod bearings looked good (.010 oversize) but they will also get new bearings. Mains also have good clearances, (.002) but not wanting to do a complete tear down just yet. Got everything cleaned up waiting on parts,,so I started to do a little brick and claw hammer body work on the fenders and now got them ready for some bondo work,,,,,,lol.
I had removed both fenders for the body work and paint and notice that both outer axle gaskets have leaked some oil,and appears the oil leaked thru the bolt holes,, doesn't look fresh but did leak at some point. It is the gasket next to the brake assemblies on both sides. I had planned to open and check out the brake shoes but not really wanting to do a complete tear down of the axles for those old leaks,,,,Can somebody offer up some hints on YEA or NAY on how to approach this issue??? The rest of tractor gaskets look good except for the PTO may have also leaked some in the past,,,? According to PO, the tractor had only been parked for 5 months,,,?
It's ironic that the PO told me he parked the tractor due to a BAD rear main seal leak as the front seal was leaking as well,,,! These other oil leaks do look real old tho,,?
