Declination slop in LX 90?

Hi....

I recently picked up an older LX90 and noticed when I change Altitude (Declination) direction with hand Ctrl.  there's a lag in movement.

For example if I set the speed to #4, it takes 5-6 seconds before I see any movement at the eyepiece.  I looked at the worm gear when changing directions with a faster speed.  I can see the worm gear move away from the spur gear when changing the direction, then moves back into the spur gear to make good contact.  After the initial change all movements in the new direction are OK.  If I again change the direction the other way it happens all over again.

Any ideas what's going on?



Thanks for any replies,  Gerry
