OIL ON CLUTCH LINING 1945 B

The clutch on my 1945 B has been getting grabby lately. I thought it was probably oil on the clutch lining and when I took it apart that is
what I found. The inmost lining was oily. What would cause oil to get on it?
Thanks for any help.
 
There's a bearing in the outer end of the pulley hub that get packed with grease. Should be cleaned and repacked occasionally. Could also be engine oil working past the main bearing and diluting the grease. I think there's a seal inside the outer bearing against the crankshaft. Have to take the pulley off for service.
 
Mike, you would be correct if you were working on a newer two cylinder like a 20 or 30 series. The A's, G's and B's never had a right main bearing seal. The engine oil from main bearing was normal at this location and drained back to the crankcase from Reduction cover / compartment. The Oil slinger on clutch actuator was the only seal on the pulley side. With that said oil from RH main bearing actually lubricates the inner clutch pully bushing. DW
 
Issue boils down to not doing as the old timers did it. If the engine is idling for any amount of time at all, one puts the transmission into neutral, locks the brakes, and engages the clutch pulley so it turns at engine speed. This a required part of the oil return system as the right main bearing sprays oil out into the 1st gear reduction cover case and it is only returned by riding up the bottom of that large gear to get squeezed off when it meshes with the clutch gear. The oil from there drops down into a collection system and flows thru a finger sized hole back into the separate crankcase just under the crankshaft. Don't engage the clutch pulley diligently and you will eventually wash your clutch plates with the oil as one big slug of it piles up right there trying to all get thru the finger sized return hole at once and it can do nothing but back up into places it never was supposed to go, like the clutch disks, on your glasses, single drops on the hood, etc. It's not so very obvious, but it's still a thing one has to be doing with the older ones.
 
So look for a pluged hole in reduction gear cover, Very cheap repair, Just clean out sludge so oil can drain back. May make tractor stop using oil.
 
I have the pully off and see the hole. It is open. I always put the tractor in neutral and push the clutch in when I get off.
 
I consider myself an old timer at 79 years old and getting the first Deere a 38 A in 1957 ans a 49 B in 1960, a 46 B in 1962, a 51 A in 1969 and a 1950 AR in about 82 and we NEVER did do that puting in netrual and enguaging clutch. Had 2 cylinders for over 40 years.
