My 1945 SC clutch has always worked great and I've wondered why the oil doesn't cause it to slip. What was the whole idea of this design and why the oil? Was it to extend the life of the plate and disc? It definitely works well - just wondering. I drain the clutch hsg with the crank case when I do an oil change and it comes out pretty milky.

The tapered axle on the 500's threw the 930's was a mistake as the milled keyway was a source of the axles breaking. Though they never broke until the axle crystalized and just the last 1/2 in broke. Ask Mert Miller. He seen a lot of them and they all looked alike. [Reply]  [No Email]

The oil just oils everthing and dispates the heat if the clutch is first engaged once the clutch is engaged the plate no difference from a dry clutch. Even John Deere came with a oil bath clutch in some tractors , it got it's lube from the transmission. And doesn't the Case tractors with powershift use it and it works more like a dump valve?

Can't explain why they don't slip, but you have an internal engine problem causing the milky oil. Could be a leaking Sleeve O-ring, blown head gasket, cracked head, or cracked sleeve. Needs attention before you damage the lower end. [Reply]  [No Email]

The oil flows out of the crankshaft into the pilot shaft then sprays out right in the clutch, keeping it wet all the time. This prevents wear. The oil then flows back into the engine oil pan via a large hole in the engine casting at the back of the engine. ---Derrol in Texas--- [Reply]  [No Email]
