I thought this subject might have been touched upon previously, but found little in a search of the forum.
My Arri 16S was serviced about two years ago, but has not had more than 1000' of film through it since. I don't think it needs another service just yet, but the last few times I ran it I've noticed that the take-up spindle sticks (won't turn) until I've let the motor run for a good minute or two and spun the spindle a bit with my fingers. I can see the spring-pulley running around in its groove just like it should, but the spindle itself just won't turn till its good and ready.
I don't think oiling the camera does anything for this part of the mechanism, as it is not linked to the oiling ports in any way.
Has anyone had this problem? Is it related to dried-up grease inside the spindle posts, or is there something wrong with the ratcheting mechanism? Any advice would be appreciated.
Who did your service two years ago? Unless the camera was dropped at a weird angle or you tried to pry the take up reel off the spindle and bent something, there is no way the spindle should be sticking. And you are right, it won't be helped by oiling the little oil holes because they are not connected. Has the camera been kept in a very moist environment?
When I rebuild that camera, I use Arri oil on those spindles, not grease. The grease can cause too much friction and drag.
You should definitely have it looked at. Again, who did the service last. If the camera has not been dropped or damaged or kept in a moist environment, maybe they just did not lubricate it properly when you had the service done. If they are a reputable shop, they may fix it for you for little charge. Or you could send it to one of the other of us who work on those cameras. Unless it is something bent or rusted, it should be a pretty easy fix.
