Shimano 'requires' two special tools, but I've rebuilt both M520 and M540 pedals using a suitable socket and self-gripping tweezers to deal with the adjusting nut. </p> <p>The exploded diagram is here:<br /> <a href="http://cycle.shimano-eu.com/media/techdocs/content/cycle/EV/bikecomponents/PD/EV-PD-M520-2235_v1_m56577569830608614.pdf" rel="nofollow">http://cycle.shimano-eu.com/media/techdocs/content/cycle/EV/bikecomponents/PD/EV-PD-M520-2235_v1_m56577569830608614.pdf</a></p> <p>Park Tool suggests that you don't need to disassemble the whole thing to regrease it:</p> <p><a href="http://www.parktool.com/blog/repair-help/spd-pedal-overhaul" rel="nofollow">http://www.parktool.com/blog/repair-help/spd-pedal-overhaul</a></p> <p>by unscrewing the notched black collar and drawing out the assembly, pumping in new grease and extruding the excess as you reassemble.</p> <p>I usually disassemble to the last ballbearing and clean it thoroughly.

There is a special tool for taking them apart. Bicycle Works might have one. Have the pedals been submerged at some point? </p> http://citycyclingedinburgh.info/bbpress/topic.php?id=14922#post-190248 Fri, 05 Jun 2015 13:21:34 +0000 jamesire 190248@http://citycyclingedinburgh.info/bbpress/ <p>Hi guys, </p> <p>I've been using a pair of Shimano SPD pedals (PDM520s) for about 18 months... </p> <p>They don't rotate very smoothly (plus they're prob full of gunk/sediment by now) but I don't know how to loosen them. Is this possible? I've just unboxed a new pair which aren't much better to be honest. </p> <p>Do I have to get a special tool to adjust this, so they spin round nicely on the cranks? Any tips or tricks of the trade would be welcome.</p> <p>Cheers </p>
