I have a Leica RM2255 that has a problem. The course feed forward and backward, on both fast and slow there is no movement. I can hear ticking sound but there isn't any movement. Is there a coupling inside between motor and lead screw that may be loose or failing. Any thoughts would be appreciated.
Thanks

Hello,
I'm having a hec of a time trying to find a torsion spring/leg spring for the hand wheel lock, Part# 0502 38987 per the Leica manual. I've tried to modify some springs that I had in hand using pliers and clamps and that didn't go well at all. I've reached out to Leica and "crickets". Any insight in this matter will be greatly appreciated.

2 RepliesHello,
I am having issues where auto mode is not working...I have checked the PCB and noticed that R63 is damaged/cracked in the middle. Will that be the source of the problem? I have checked the test points as well in TP2 and everything seems to be working. Any help will be appreciated! Thank you in advance! RE: Leica Microsystems - RM2255
