Re: 1965 6.6HP Engine Teardown
The parts I was removing were in good shape and the workmanship showed a skilled level. Jug was a 7.6, lifters had been replaced, good interference with piston & wrist pin with light evidence of old oily residue.
I had performed the usual initial removal of the L/H axle housing and cleaned the sump of sludge when I purchased the tractor a few years ago. Got it running, no spark, and parked it due to the projects ahead.....
Removed the spreader bolt and found the second surprise inside the crankpin. Sludge, new sludge. Just some but enough. Took some of it and dissolved it in gas. Inserted a magnet in the mix and it looked like a porcupine. Something steel is wearing!
This prompted the disassembly of the crankshaft. Found the crankpin and rod in good shape. Minor trace of sludge behind the drive pinion allen head screw.
Time to located where the metal is coming from. In addition to the engine teardown have to look into the tranny.
