Author Topic: super simplex locking up Will Kutler Phenomenal Film Handler Posts: 1506 From: Tucson, AZ, USA Registered: Feb 2001 posted 03-02-2004 11:53 PM                     First, take the projector off the soundhead and run the soundhead by itself. If it locks up, then it is either the motor, or a bearing in the gearbox. Make sure the gear box has the proper oil level. If the gearbox runs ok, then it is something to do with the projector head. Use the books available on FT to trouble shoot the "head". On the Super, the gear shafts rotate in the main casting. You may need to inspect the shafts and castings for burrs, which will require some disassembly. Are you properly lubing the projector head? Are the oil tubes blocked? Are the gear shafts running true? Are there damaged gears, or gears with excessive wear? You need to use a logical approach to troubleshoot and isolate the problem. Super and Regular/Standard double bearing intermittents were almost identical, except for the the style and placement of the oil filler tubes. I never knew that Supers had intermittents with removable outer bearing ends?  |  IP: Logged Daryl C. W.

I am refering to the 1050 and the 1060 simplex models.  |  IP: Logged Bob Koch Expert Film Handler Posts: 183 From: williams ca Registered: Nov 2001 posted 03-03-2004 12:10 PM                     Still don`t know if the sprocket has a staking screw or taper pins. If you`ve taken the movement apart the starwheel shaft should turn freely and there should be barely perceptable end play. Since the movement was OK before you changed the sprocket I think the trouble is in the star shaft. If you had to force anything when removing the old sprocket you could have sprung the shaft.  |  IP: Logged Dave Ganoe Expert Film Handler Posts: 119 From: Point Marion, PA Registered: Jun 99 posted 03-03-2004 12:32 PM                     The sprocket uses 2 pins to hold it in place. The old pins came out pretty easy. I took the whole intermittent apart again and removed the cam which came out easily, the other shaft did not want to come out but after some light tapping it came out. Seemed a bit discolored and until I took it out it did not want to turn freely. cleaning it up and applying some fresh oil seem to loosen it up. Putting it back together went ok but when I run it there is a knocking sound like the cam and the other shaft that drives the cam are rubbing. if you tighten up the balancer that attaches to the back of the intermittent it gets rid of the noise but causes to much drag. I dont understand what keeps the drive shaft of the intermittent from moving inward toward the cam and rubbing together. Forgive me for not using the proper names of the items but its the best I can describe what is happening. I think bottom line is I will have to get another intermittent. Will a standard work in a super? At this point Id take what I can get.  |  IP: Logged Gordon McLeod Film God Posts: 9532 From: Toronto Ontario Canada Registered: Jun 99 posted 03-03-2004 07:22 PM                     The super the standard and the regular simplex are the same movement as did the wenzel ace the gardnier the ballantyne BW and the devry's with a different flywheel to allow the chain drive probably the most used in different machine movement ever Did you use a v block to remove the taper pins if not the odds are you have damaged the shaft or the bushing it seats in  |  IP: Logged
