I just got a pair of Wellgo Look-style pedals in a trade, and one of them is a bit sticky. I'd like to replace the bearings and the grease, but I can't quite figure out how to take them apart.
It would appear that I need to loosen the splined plastic "locking sleeve" from the body of the pedal itself, as per this photo:
Do I definitely need to get a proprietary tool to loosen that? What comes after that step?
