Celestron C-GEM Backlash

[HCR32]

Hi, anyone have any links to how to reduce backlash in a cgem mount. The mount has a bit of backlash nothing dramatic but enough to need an adjustment.

The CGEM worm to ring gear mesh can be adjusted by loosening 4 bolts which hold the worm carrier then adjusting 2 grub screws, similar to the EQ6 described here: http://www.astro-baby.com/EQ6%20rebuild%20guide/EQ6%20worm%20alignment.htm

You just need to be careful not to overtighten the mesh and cause binding.
