CI-700 - D and RA locks don't work

Hi all. I was wondering if anyone could advise me on the declination and RA locks on the CI-700. Mine hardly work at all. There are two on each axis and not one will lock down. I can't figure it out, as it looks like the bolts just go down in there and clamp down. Is there a material under the bolts which could be worn out? Thanks so much for any help. Glen Ward

The ball bearings that bear on the clutches can be replaced, which might improve the locking action. It sounds like the friction clutch material in your clutches may be worn down and need replacement though. I would contact Michael Downing - just search for his user profile here on Astromart and send him a private message. He used to offer a rebuild service for these mounts and he may still be doing it. This yahoo group is also a good source for info on these mounts:
