Author Topic: Century MSA belt Richard May Phenomenal Film Handler Posts: 1057 From: Floral Park, NY USA Registered: Aug 2004 posted 11-15-2008 10:31 AM                     This should be a quick one. Century MSA projector. 1725RPM motor. What belt do I need?  |  IP: Logged Jim Cassedy Phenomenal Film Handler Posts: 1661 From: San Francisco, CA Registered: Dec 2006 posted 11-19-2008 05:28 PM                     Richard- this may not be as easy as it sounds. I'm not an expert on this particular model of Century, projector but there are some variables that can affect the answer. For example, some are driven by a drive belt directly from the motor to the projector. Others can be driven indirectly through the sound head which itself may be driven either directly or through another drive belt. I think more information is needed, such as the type of soundhead and drive arragngement attachedbefore anyone can answer your question accurately.  |  IP: Logged Monte L Fullmer Film God Posts: 8367 From: Nampa, Idaho, USA Registered: Nov 2004 posted 11-19-2008 06:18 PM                     What is your sound head - is it an R3 standard soundhead that used that large square tooth drive belt? Or, do you need the ribbed belt that runs from motor to soundhead? Check your dealer on this info.  |  IP: Logged Richard May Phenomenal Film Handler Posts: 1057 From: Floral Park, NY USA Registered: Aug 2004 posted 11-19-2008 07:38 PM                     As far as I remember, the MSA is a direct drive projector. It only has one belt. It is the toothed version. I thought only the SA had 2 belts.  |  IP: Logged Monte L Fullmer Film God Posts: 8367 From: Nampa, Idaho, USA Registered: Nov 2004 posted 11-19-2008 08:37 PM                     My mistake. The SA that I'm used to uses a ribbed belt since it has an induction motor to drive it. You've got a sync motor on it which needs the toothed belt. Still, check with dealer for the right belt.  |  IP: Logged Jim Cassedy Phenomenal Film Handler Posts: 1661 From: San Francisco, CA Registered: Dec 2006 posted 11-20-2008 09:59 AM                     quote: Richard May As far as I remember, the MSA is a direct drive projector. And I seem to remember that the MSA could be ordered configured for direct or indirect drive. Whatever! - - I think we all agree a little more info is needed to come up with a the right answer to this question here. Contacting the dealer as suggested is probably a good way to start.  |  IP: Logged Scott Norwood Film God Posts: 8146 From: Boston, MA.

There's a number on the outside of the belt that specifies the size and type. Type that number into the search box on the McMaster-Carr web site, and you'll be able to order them there. At least that worked for me when I last ordered spare belts.  |  IP: Logged Gordon McLeod Film God Posts: 9532 From: Toronto Ontario Canada Registered: Jun 99 posted 11-20-2008 01:18 PM                     SA drive from soundhead single shutter air cooled DA drive from soundhead double shutter air cooled SAW drive from soundhead single shutter water cooled DAW drive from soundhead double shutter water cooled MSA Direct drive single shutter air cooled MSAW Direct drive single shutter watercooled MDAW Direct drive double shutter watercooled The direct drive could be poly V belt or toothed belt for non sync 1725rpm motor or a different pully arrangement with toothed belts for 1800 sync operation  |  IP: Logged Sam D. Chavez Film God Posts: 2153 From: Martinez, CA USA Registered: Aug 2003 posted 11-20-2008 07:38 PM                       At this point the plate on the projector is meaningless as someone may have converted a direct drive to sound head drive of other way around. Grooved belt drive might now be toothed and use a sync or not sync motor. The point is Century's are very easy to modify and there are tons of parts for them.  |  IP: Logged Mark Gulbrandsen Resident Trollmaster Posts: 16657 From: Music City Registered: Jun 99 posted 11-21-2008 02:20 PM                     Sam, You're absolutely correct but somehow I envision this one as being driven by a squirrel thats being fed popcorn...  |  IP: Logged Louis Bornwasser Film God Posts: 4441 From: prospect ky usa Registered: Mar 2005 posted 11-21-2008 09:05 PM                        IF it's not modified, use a BE-908 (poly vee drive) from any dealer.
