You may remember that I asked if anyone had a used tensioner they didn't want - I was going to look at the posibility of re-manufacturing the plastic part that shatters. Anyway, Ricelmus (cheers mate) sent me his old tensioner. At first it looked straight forward to make a replacement gear in aluminium, but when I removed the existing plastic gear I found that it was actually moulded around the bearing so that it wouldn't come off in use(see photo). This is where the problem arises. There is no way I would be able to get an aluminium gear to stay on the bearing with any degree of confidence. I could make it a good, tight push on fit, but with the heat generated by the engine, I just couldn't guarantee that it would stay on. Adhesive is no certainty either - again due to expansion caused by heat differential between the gear and the bearing. If there wasn't any heat involved it would be more straight forward. As far as i'm concerned this project is now a dead duck, but i'm open to any bright ideas anyone has.
