I'm having a problem with my OWB. For some reason I keep getting oil on the bearing and shaft which causes it to slip. Ive taken the bearing off several times already to clean it out. Each time I replace the bearing it works fine till the truck has been running for a while. Then when I try to restart the engine the bearing slips. The only way to get it to work is to take it out and clean out the bearing again. Needless to say this is very annoying. I don't know why I'm getting so much oil on the shaft and the bearing. Does anyone have any ideas or know how to work around this? Thanks.
