Normally I can get the cone lock not to secure in the correct position, but not on my PD-M646's (red caged DX jobbies), which are are modified PD-M505 with a cage. Now the tool to service PD-M520 & 540 pedals is about a fiver.

but the one I need is £65 bloody quid WTF?

Has anyone got any suggestions or offer help?

Ps) Both tools are conveniently listed in the park overhaul page.

I used a small flat blade screwdriver to hold the cone still & a small/thin walled socket to do up the locknut as tight as i could.
Worked ok :wink:

I agree Gruff, that's the normal prcoedure, but the, bearings/cone/lock nut are about 2cm deeper than normal on these buggers and that technique isn't usable. I'm thinking right now that I@m going to have to buy box spanners 8mm & 11mm and then modify them so they fit inside each other and inside the pedal.

Mine are the red M636's, still no luck with the screwdriver, have bought some box sockets to modify & hopefully take the fiddling out of the job.
