Finn Bjerke Posted May 11, 2022 Share Posted May 11, 2022 Took Sherman apart an wheel motorcap looked very strange, it's scraped. By what or how I don't understand. Advice appreciated https://ibb.co/6BFNjH0 Quote Link to comment Share on other sites More sharing options...
gon2fast Posted May 11, 2022 Share Posted May 11, 2022 Can you take a picture of the inside of the shell (w/o the motor of course)? Quote Link to comment Share on other sites More sharing options...
meepmeepmayer Posted May 12, 2022 Share Posted May 12, 2022 Wow! One would think you would feel/hear if the entire motor side cover scrapes. But what other explanation could there be? How does the other side of the motor look? Also scraped (or whatever it is)? Get a picture of both motor sides in addition to the inside of the wheel well.

Mantraguy Posted May 14, 2022 Share Posted May 14, 2022 I think it should probably be pretty obvious before or while you're taking it apart. There are only so many things in there that could rub - and you'd definitely hear it while riding! Did you encounter anything on the inside of the shell (accumulated mud etc.)? Could the pedal hanger be bent enough to cause a rub on the inside of the shell? You'd feel that though... Quote Link to comment Share on other sites More sharing options...
Finn Bjerke Posted May 16, 2022 Author Share Posted May 16, 2022 New bearings - problem solved ... Rather surprising. Took for bloody ever. Pedalhanger was very OK --- this is still a mystery but Sherman works well - new bearing from SKF - very nice indeed. Quote Link to comment Share on other sites More sharing options...
meepmeepmayer Posted May 16, 2022 Share Posted May 16, 2022 Not in a thousand years I would have guessed that bearings could be responsible for damage like this. Did they push the motor cover too far out, and then something could scratch it? 1 Quote Link to comment Share on other sites More sharing options...

Freeforester Posted May 19, 2022 Share Posted May 19, 2022 Did you forget to discharge the capacitors, or what caused the damage to the Motherboard? Did you originally change only one bearing, or both? Or could there possibly be any issue with the axle causing premature failure of the bearings? Apropos environmental conditions - are you riding on sand, or gravel tracks, or where debris could have got caught between the shell and the casing? How does the inner side of the shell look on the side where the damage has been occurring? Sorry for the interrogation, just trying to understand and disseminate the ‘flight crash investigation notes’ Quote Link to comment Share on other sites More sharing options...
Finn Bjerke Posted May 24, 2022 Author Share Posted May 24, 2022 I dropped a screw on the control board... Quote Link to comment Share on other sites More sharing options...
