Author Topic: Help: Pro35 Int. Movement problems. Shaun Flichel Film Handler Posts: 42 From: Regina, Sask., Canada Registered: Sep 2002 posted 11-18-2002 11:44 AM                     Dan, I will once again try to explain this, but I'll try in better detail, I was tired when I wrote the first reply. Ok, you have 3 bolts holding in the intermittent movement, these should be equally tightened like lug nuts on a car, I bet your problem occurs only when 2 of the 3 are completely tightened, as well as the 3rd one. If you have all 3 tightened, loosen 2 of them maybe 1 turn each, see if it still binds, if it does then loosen the 3rd alittle and it will probly loosen up, if this happeneds, it is a backlash problem. Ok now, you have a splined gear and the other whatever you call it, plasic/fiber gear. The problem lies with the plastic gear, and as I said before, the holes on the movement for the bolts are alittle oversized to allow for adjustment, all you can do is loosen the movement, twist it alittle and retighten, it could take awhile to find the spot, ive had this problem with every machine ive done, and have become pretty good at it. Also try removing the movement and turning the shutter over, if its free, then good, but dont under any circumstances try to force it to turn when its binding with the movement installed or you risk breaking that gear. Also, turning the sprockets over by hand will be very hard nontheless, theres quite a gear ratio there, think of a rear whell drive car with it in neutral and the rear end jacked up, its easier to turn the drive shaft by the rear wheel instead of the drive shaft itself. Anyways, get back to me if you have tried this and have anything new to report.

If you can't I would look at the mesh and the condition of the shutter drive gear to the verticle shaft. Also I have had cases of the shutter shaft having a slight warp in it  |  IP: Logged Dan Lyons Jedi Master Film Handler Posts: 698 From: Seal Beach, CA Registered: Sep 2002 posted 11-19-2002 07:30 PM                     Thanks for all the help. I got it all put back together, and filled with oil. Hooked up the motor, seems to run all right. Thanks for all the help.

A note for anyone researching this in the future; Often, when removing the intermittent sprocket assembly, it is sometimes helpful to also remove the aluminum plate that separates the shutter compartment from the threading compartment. Be very careful here, the plate screws are 10-32 X 3/4 while the intermittent sprocket assembly screws are 10-32 X 1/2. Attempting to thread the longer screws into the sprocket assembly will, if forced, begin to withdraw the threaded inserts from the projector frame. This can result in an oil leak that you can have one hell of a time getting rid of, as well as an intermittent sprocket assembly that will never "set" just right. Trust me on this one.  |  IP: Logged Dan Lyons Jedi Master Film Handler Posts: 698 From: Seal Beach, CA Registered: Sep 2002 posted 11-20-2002 02:53 AM                     I agree with Rick. From the start of the project, I've kept the various parts and screws in separate labeled bags for that very reason.  |  IP: Logged Paul G.

We would like to know for future reference. Thanks  |  IP: Logged
