About this time last year I bought some Shimano SPDs and from week two one of them clunked. I want to swap them on to my 'best' bike but obviously need to change the bearings.

Q - What size are the balls and is there anything tricky I should look for/ special tools needed along the way.
I've stripped lots of quills but never done a SPuD.

What type? I vaguely recall that some are non-serviceable. (I certainly b*gg*r*d up my A520s when I tried to adjust the bearings.) Have a look at the technical docs on the Shimano site (if Shimano....).
There is also some guidance on the Park Tools website: note special Shimano tools are needed

3/32" (very, very small).

If your SPDs have a dustcap on the outboard side DO NOT disassemble them. Without the expensive tool it's almost impossible to adjust the bearings afterwards. If they have a splined collar round the axle end, you just need the plastic tool to fit that - often supplied with the pedals. The whole lot comes out as a sort of cartridge which is then easily serviced. One side is left-threaded, though.

You need 62 3/32" bearings for the double sided MTB versions I have.

The bearings are a fiddle to handle being so small and you need a TL-PD33 or a PD-63 (smaller sizes) tool set to easily tighten the locknut.

Hello,

Have had problem with left side of 2 pairs of Shimano PDM 520 double sided pedals. Obtained plastic tool (FOC) from supplier. After removing pedal body nut adjusts quite easily. Put a bit of extra grease on then replaced body, no further problems after quite a few thousand miles.

Hope this helps.

The tool is very cheap, i got mine for £2. However it is not absolutely nescesary the job could be done with mole grips and some padding to protect the pedal.
I would recomend using the tool to protect the pedal if you can but the other option is quite possible.

They pedals were quite easy to adjust once opened, the whole job was amazingly easy. As I did not try and remove the bearings at all.

Check whether you need the cone adjustment tool from the shimano website. If you need it don't undo the cone without a tool to hand. You will not, I repeat will not, be able to adjust the cone without one.........Mind you I borrowed one off a very nice chap on this forum :wink:
