Pedal bearings

anonymous coward said:

I have some Shimano M324 pedals whose bearings are
beginning to feel grainy
- the rubber seal on the worst one is slightly damaged. I
gather it is possible to service the cup & cone bearings
- but I can't find a service manual anywhere.

Should I just ride them until they fail, or would it be
worthwhile greasing them and possibly changing the
bearings? My worry is that the cups & cones may not be
replaceable, so if I don't do something now they may be
permanently damaged?

Drip some 30W motor oil in there.

When the damage is apparent it's usually too late to
lubricate, the races are probably bad too.

For replacement seals, which are generally not available at
stores, roll up some aluminum foil into a tight ball, pound
it flat, and cut a bit oversize, and wedge it in, sometimes
it don't wedge very well so one must use small gauge wire to
hold it in place.

Try a google search on groups, there are a few old threads.
There's also a section on parktools.com on servicing
Shimano pedals.

Thanks, that's pretty neat.

I did do, but I didn't find the info I was looking for. The
Park-Tools section shows quite a different type of pedal,
"shimano 324 pedal service" finds only 2 threads, and the
Shimano website's link to a service manual seems to be down.

I guess I could have put my question a bit more clearly. I
already know how to service cup & cone bearings, but the
tool I would need is quite expensive. If the bearings aren't
too bad, or if they're completely replaceable then I'll buy
it and service them. But if they're too far gone, and can't
be completely replaced, then I will save money & time by
doing nothing...

I have the Shimano SPD M525 pedals which is also ball
bearing. I tried to adjust the bearings without using the
parks Shimano pedal tool with a screwdriver and a socket.
After about 40 minutes of fussing to get the adjustment
right and thinking I had the locking nut tight enough, the
bearings tightened up after a few hundred miles. I ended up
purchasing the Shimano tool, which is well made and a must.
Adjustment takes about 2 min. -tom

Generally I can find a socket for a ratchet wrench to make
the inside circle.

I've had a few problems with pedal seals, too.
