The reason I removed the hub was to check the bearing as the engine was rebuilt approx 8 years ago (was told had covered little miles since) and after stripping the front end down I found some poor quality items fitted. I understand that there were a batch of bearings with resin cages that could potentially collapse in service so I didn't want to be riding wondering if my backside was sitting on top of one! Having said that the last time I rode the scoot we were 2 up with luggage and the rear wheel was solid. So I looked anyway. The bearing had no markings on the outer or inner edge? I removed the Rolf seal to find a metal cage. Curiosity satisfied so I just fitted a new MB seal and re fitted the two plates using the old nuts and washers with a smidge of loctite. Now I'm thinking........
While I had the engine out of the scooter should I have stripped the gearbox and just replaced all the bearings?
Read a thread on here (after I had fitted) where someone replaced a rear hub bearing seal with an MB one and it leaked!
do not grease the cone bud I had a Casa resin type rear hub bearing that collapsed, the rollers cage broke into 3 parts, it leaked oil, but that's all, no hub movement as the rollers were still contained in the inner & outer races, mine went on the way back from Blackpool on M62, you can imagine what went thru' my head when I stripped her to change the seal & all I got was an apologetic letter & a new bearing
