Finding rubber detritus in the crankcase I figured the rubber slipper was disintegrating and so obtained a replacement (I think it was a T120 part) at great cost from the US. I removed the cover plate and found that the part had been cleverly modified with a steel base and bonded brass slipper/chain interface. There were more rubber pieces that I could now clean out, so clearly it used to have the factory fitted Triumph part.
Is this a recognised modification and should I be concerned? Will this accelerate wear of the primary chain?
The part is showing some slight wear where the chain has been running along the brass, but the brass is around 3mm thick so its not a concern. Other than that it would seem to work well.
