Stripping/Rebuilding EQ6R Pro mount

Decent guide to rebuilding/tuning the EQ6-R Pro mount

Item details

This procedure will guide you in setting up the EQ6/Atlas worm engagement and also aligning the motor gears after the Declination and Right Ascension reassembly. These steps are best carried out with the EQ6 head mounted onto its tripod or some other type of stable base.

The worm setting procedure - especially for the RA axis is very hit and miss and you will probably need to go through it several time to find the 'sweet spot' where there is both no play in the mount and the RA motor can turn the mount smoothly with no motor stall or gear binding.

Play / tension in the mounts axis are controlled by three elements. The worm carrier set screws, the end float adjusters and, to a lesser extent, the motor engagement. If you are having problems with a binding motor its best to slacken the motor away altogether. Get a good setting on the worm carrier set screws and only then tighten the motor back down. This symptom will show if all appears well UNTIL the cap headed screws are tightened down. If this happens then the motor is installed too tightly causing the motor gear and the worm gear to bind.
