Ritchey V4 Pedals - Service bearings

[Griffin]

Hi all

 

I got an oldish pair of Ritchey V4 pedals that I love using. The right-hand one needs bearing grease/service badly...I can feel the grind on every pedal stroke!

 

The problem I have is that the cap (which needs so come off to get access to the spindle/bearings) uses a hex bolt (6 side allen key) to unscrew and the hole has been rounded so the allen key just slips

 

I thought of drilling the cap out, but where would I find a replacement? Maybe I could use some pratleys putty and form a new allen key hole, but I am not sure if this would be strong enough to work.

 

Any suggestions? Anyone out there with a pair of Ritchey V4's that they would sell?
