Just watched a YouTube clip of someone demonstrating how to adjust backlash in a Skywatcher EQ6-R Mount ( attached snapshots from YouTube )
They just used a small Allen key and adjusted a screw roughly a eighth to quarter turn on a screw between the drive pulleys

Has anyone seen this YouTube clip or adjusted backlash in their EQ6-R Mount

I have 2 of these mounts and yes they do suffer from backlash but not as severe as my old HEQ5

I welcome comments and or advice whether this procedure actually works !!

Thanks in advance
