Author Topic: Lifespan of dry intermittents Christopher Seo Jedi Master Film Handler Posts: 530 From: Los Angeles, CA Registered: Jun 99 posted 08-31-2002 09:26 AM                     I'm curious as to how long an intermittent movement can generally run dry before seizing. I've only heard of one intermittent that seized during the course of normal operations due to obstructed oil feed tube (Simplex 35), and was wondering how long it was probably bereft of oil before calling it quits. This is assuming the movement has residual oil, but is otherwise drained of oil.  |  IP: Logged Gordon McLeod Film God Posts: 9532 From: Toronto Ontario Canada Registered: Jun 99 posted 08-31-2002 10:51 AM                     Well years ago at the Toronto Eastons Centre we had a Ernamann 9 that ran bone dry for a Loooooong time and finally seized. Imperial oil estimated that the varnish on the star was about 5 months of no oil Also at the same theatre several Prevost's ran dry for some extended periods film done way wrong  |  IP: Logged Pete Naples Phenomenal Film Handler Posts: 1565 From: Dunfermline, Scotland Registered: Feb 2001 posted 08-31-2002 12:48 PM                     One of the Westrex 7000 sites I service occasionally got a new operator. He didn't know where to put oil in the 7000, didn't think to ask. After 8 months of all day running with no oil, he started to comment that the machine was very noisy and the picture was jumpy. I took a look, and finding no oil, topped it up. I was horrified to see orange particles of RUST floating in the site window. Needless to say a refurbished intermittent was required, and yours truly had the the thankless task of fitting it. The working surfaces were pitted and badly scored, there was also areas of blueing, which would indicate fairly high temperatures ahd been reached within. Oddly enough the box never siezed! On the other side of the coin I've seen an FP20 intermittent sieze solid, which had plenty of oil in.  |  IP: Logged Gordon McLeod Film God Posts: 9532 From: Toronto Ontario Canada Registered: Jun 99 posted 08-31-2002 01:11 PM                     I once had a vic4 movement that was bound up with the pin in the slot of the star wheel. After getting it appart we polished the slot face to remove the scoringwith a dremel and valve grinding compound filled it with oil and 4 years later it is still running. At another site a projectionist that was being let go put honey in all 7 FP20's and 2 DP75's. They ran only a day before requiring a rebuild I also know of a bauer U2 that someone put green soap into mistaking it for the green bauer oil. Siezed up very fast but when I took it apart it sure was clean  |  IP: Logged Richard Fowler Film God Posts: 2392 From: Ft.

One of our theatres in a very remote location blew 5 of them within a 6-month period.  |  IP: Logged
