Topic: Wheel bearing question

[WHALEMAN]

This is a question for the experts. I have changed wheel bearings on 750's and others for years. When you get the new bearing it always has a little grease in it but it never seems enough. I have changed to using the bearings with a rubber seal on each side (2RS). Should I pack the bearing full of grease as it seems that might be too much in a double sealed bearing and create heat. Does anyone know for sure if the bearing manufacturer knows best or should it be packed full? Dan

some bearings are sealed from the factory some are not. insist on the sealed type you do not need to pack them as they are already sealed. I however use a white lithium grease and coat everything before assembly. I figure an extra bit of lube over everthing cannot be a bad thing. some bettter brands to look for are FAG or ntn .good luck,Fergie.

I've always been told that too much grease can be just as bad or worse that not enough since it impedes the rotation of the inner race and the balls, which could cause galling, heat build up and premature bearing failure.  I have installed double sealed bearings on my bikes without any additional grease, and have never had any problems for many, many miles.

I agree...double sealed pre-packed FAG is what I installed on the front and back of my KO last spring.  No need for additional grease.  Good luck with your project.
