Shimano M520 bearing play
I've taken this pedal to 2 different LBS's, and both have told me that this pedal is not serviceable. One even suggested that it would be dangerous to use this pedal at all anymore, and directed me to their pedal case to buy the M540s at double the price.
But I *know* I've seen a PDF file on the Internet for servicing these pedals.
The problem I'm having is that the axle has a lot of play (about 1mm) on one of the pedals. Enough play that I feel it creaking when pedaling hard, and can feel the axle clacking around when hitting cracks/potholes on the road.
Should I just buy the TL-PD40 tool and do it myself? Is it hard? How would one adjust these pedals for no more play?
