My recently acquired '52 K model hasn't been started in decades. The engine and transmission turns by hand but is stiff and hard to turn.
It appears the old oil has dried up and is more like tar than oil.
Since to access the transmission requires splitting the cases, I am trying to be creative.
I have removed the engine from the frame and removed the primary cover and the cover over the cams. I have disassembled the clutch, leaving the basket in place.
Next, I have placed the engine in a large plastic laundry tub. The engine just fits.
Now I plan on adding diesel fuel to the tub until the level is a little above the clutch main shaft. Once or twice a day I will rotate the clutch shaft.
I expect that eventually the diesel will dissolve the old residue and turn freely.
Diesel fumes should not be a problem and I don't think I am in danger of blowing up my shop.
So what is wrong with my crazy idea?
