Rear Main Bearings

[Tony Press]

Russell,

"I have heard it said that moisture plus periods of inactivity promotes rust and pitting in the rear main. Could a fully sealed bearing minimize this  by virtue of it being coated in grease not used engine oil? Would the bearing run hotter not being flushed in engine oil? In other words are sealed rear mains a good idea?"

The original inch series of Roller Bearings are not available with seals and if they were it would be very difficult to fit.

Also the bearing seals used, while good for keeping grease in would most likely allow the engine oil to get into the bearing and wash out the grease.
