Have drained both crankcase and transmission, flushed crank with kerosene but haven't removed trans cover yet to flush. Removed pulley and clutch assembly - now for the dumb question - how does the pulley gear and first reduction gear get lubricated? On the 50 B, there is a filler cap at the top to fill the reduction gear cover. Is the only filler on the 40 B located at the rear of differential just below the powr-trol?
Thanks,
Bob

The first reduction gear and pulley gear, along with the clutch fork and collar all are lubed by splashup from the crankase. The bearing in the pulley housing needs to be greased though. CalJim

What keeps the moisture, dirt and grit out? Doesn't appear to be a seal anywhere on the pulley assembly.
