It seems as if there is more interest in providing a rebuilding kit than doing the rebuilding so here is what I can do:
4 ceramic hybrid bearings and delrin collars for 300.00 plus shipping.
I'm having trouble getting any more of the C4 clearance steel bearings so for now I'm only offering the ceramic bearings.
Please do not buy any kit with the C3 bearing or buy a bearing replacement that is C3 clearance as they will fail far sooner than you would like.
Here is a picture of the front and rear of the new bearing with collar installed.
