Help with HEQ5 Pro backlash

[lensman57]

Hi ,

There is a slight amount of play in the RA axis of my HEQ5 Pro. I know that this is to do with the worm gear not the motors as I have modded the drives to belt drive.

There is a grub screws at the bottom  of the RA assembly under the counter weight shaft . My question is if this screw is to adjust the backlash of the worm gear and if not how could this be done without taking the mount apart.

Many thanks for your help and advice.

Regards,

A.G

The problem I found (tried to ignore for a long time!) was indeed cured by the "end float"

adjusters... conveniently located under the rubber bungs. Ironically the easier tweak.
