Look Keo bearing servicing--Help!

[Steve in SLO]

I have a set of Keo Sprints that are developing some free play and I have heard that regreasing the bearings can help this. I searched other forums and have learned that others have used 12 pt 18mm or 19mm closed end wrenches to unwind the axle from the body. I tried with my Craftsman 18 and 19mm wrenches and neither fits. Anybody got another idea? Is there a tool for this? If so, it doesn't appear in the Look website.
Thanks in advance for any help.

Steve, are they part of the recall? Then you can get the free innner replacements from Art's

Hi Guy,
They're '07s, so too new to be part of the recall. Thanks for the thought, though.

The Sprints need a special plastic adapter which fits the axle nut.
Call Look or look around (punny huh?) on the net/LBS.
The higher level models use standard wrenches etc.

R2D2,
That's what I suspected. Thanks!
