Pedal bearings

[POHB]

I've got a problem with adjusting the bearing inside my pedal, the
cone has tightened itself up so the pedal no longer turns freely.
This is a pain as it has a clip one side and flat the other like this
http://www.evanscycles.com/product.jsp?style=10570

There's the usual two nut arrangement inside with one providing the
bearing cone and the other being a lock nut, the problem is that they
are both recessed inside the pedal so I can't get a spanner on the
cone while I tighten the lock nut against it. Consequently, althougn
I can tighten or loosen it I can't make it stay put and it just
tightens itself up when riding.

Any ideas?

I have just explored this, having been bequeathed a pair of worn M540
SPD pedals in need of maintenance. Newly informed,
I suspect that Messrs Shimano will require you to purchase a set of tube
spanners one of which fits inside the other, in order to get to those
cone adjusting nuts. I suspect the bearings may be shot if they've
seized.

I stopped the adjusting nut turning with a thin piece of metal, a nail
file, while I turned down the lock nut with a thin walled socket. It
will take several goes to get it right.
There is a proper tool you can get but it is a rare thing. I got one
from wiggle but it was for smaller nuts that the ones on the M324
pedals.

if there isn't a locking washer between the nut and cone, then I just
use a wide bladed screwdriver to top the cone turning and a suitable
size socket on the nut.

The traditional method is to wedge a screwdriver against the larger nut and
turn the smaller with a suitable spanner. This (as with most locknut-cone
arrangements) may take several tries to get the adjustment just right; a
trick that helps is to get the two nuts tight enough that they will not
seperate when the axle is turned; then you adjust the pair for bearing
freedom, then you lock the cone. Debug, edit, compile again.

rare, as they cost more than a new set of pedals!

So I went to a few shops at lunchtime. The one that actually
understood what I was talking about said that their workshop uses a
jealously guarded thin box spanner, also that they knew a man in
Camden who ground down a socket spanner specially for the job.

However, I found and ordered one of the gadgets from ChainReaction at
considerably less than the cost of a new set of pedals.

Hope it fits...
