Just out of curiosity - which is preferable, sealed or unsealed? Personally I like the idea of oil sloshing around bearings - partly for confidence in their lubrication, but also for cooling. However I imagine the seal would keep out those iron filings these gearboxes seem to generate so much of! Then again, the original bearings seem to last pretty well.
