We are all on the same boat. Of course this is an issue that Specialized and Brose should work out. I did pack the gap with SKF bearing grease before mounting the oring. But as I am sure you can understand I can not open the motor to do any modifications as this will void warranty. If I had a...
Good points. Of course the actual wear is unknown. But note that there is no movement between these parts as long as the crank arm (pedal) and spider (chainring) is moving together, as they will normally do. And when the crank arm rotates it now only cause wear on the plastic ring and the inner...
Specializeds intention of using the blue thermal gap pad between the motor and the frame is to better transfer the heat from the motor to the frame (cooling). With rubber instead you will get less cooling and the motor could get hotter than with the thermal gap pad. How ever, the pad is quite...
I would assume that there is an internal seal, but who knows. Anyway, I plan to put on an o-ring for sealing, backed by a plastic ring that is in contact with the crank arm. The oring is 23.52x1.78. The plastic ring is from a Race Face crank, OD 29.2, ID24.2, thickness 1mm.
