Problem just started today. The lens chuck will not move all the way over to hold the lens.
I have tried squirting wd 40 on the shaft and cycling the chuck in and out . It first started with the chuck only moving an inch or so but with repeated cycles it now moves more but it is still about 5mm short of contacting the lens. After about 50 cycles it seems to go back to moving only and inch then will gradually move a little more each time but never gets to the lens.
I have tried setting the chuck pressure from low to high, no difference.
I have tried tugging on the shaft as it moves to “help” it out. Nothing.
It does not seem to be binding and isn’t making any unusual noise. It just stops in the wrong place.
In order to use the machine I have had to attach a second rubber lens pad to the existing rubber pad and that seems to work for now.
This machine is 9 years old and I have had it since new. It has been professionally serviced by Santenilli several times and is in great shape. It may be time for the rebuilt 9000 have had my eye on for a while.
