Hi all,

 

My AZ-EQ6 mount over time became stiff in AZ axis. It's quite hard to push it around and it squeaks.

Slewing with motoros appears to work fine and quiet.

I use it in AZ mode with a 12" 18kg Newtonian (with three 5kg counterweights) 

I tried re-balancing it - doesn't seem to have effect.

 

Any ideas how to fix it?

This may be a dumb question, but have you made sure that the AZ clutch really is loosened all the way when you try to turn the scope? As the clutch handle sits between the fork, it has quite limited range. That’s why there are multiple threaded holes for the clutch handle, so that you can pick one that allows full range of handle positions to both directions (open - close) - I can easily imagine a situation where the clutch handle hits the fork, before the clutch is fully released. And over the years, the ”sweet spot” of the handle might slowly drift...

I made sure it is really loosened (I'm aware of the multiple holes system).

Actually it's so stiff I usually don't bother tightening it at all (even when slewing with motors)
