Author Topic: Century main drive gear Tommie Evans Expert Film Handler Posts: 116 From: Birmingham, West Midlands, UK Registered: Sep 2004 posted 05-23-2006 01:32 PM                     I've searched this forum with no results. . . In the Century MSC/SA-TU projector manual it states that you can remove the main drive (horizontal) shaft and gear without removing the intermittent/shutter/vertical etc etc. However on the JJ1STA (35/70mm century) I've heard you can also remove the main drive gear without removing anything else from the casting. Is this true? But on the SATA model do you need to remove the inter, vertical, shutter shaft before getting the main drive gear out?  |  IP: Logged Steve Guttag We forgot the crackers Gromit!!!

If you are replacing the set (both steel and fibre) then yes, you always need to pull out everything. The vertical shaft that holds the GR-4 or GR-182 (Standard or Direct Drive)steel gears is captivated by the shutter shaft and intermittent so they need to come out first, then you can pull the vertical shaft.  |  IP: Logged Pete Naples Phenomenal Film Handler Posts: 1565 From: Dunfermline, Scotland Registered: Feb 2001 posted 05-24-2006 02:14 AM                     I would also add, that if you're in th eposition of having to replace the fibre main drive gear, you should replace the steel gear on the bottom of the vertical shaft at the same time, they work and wear together, and if you replace just the fibre, you'll find it will probably wear in double quickt time. How are those hammered old Centurys going Tommie? They were well past their first flush of youth when they came your way!  |  IP: Logged Louis Bornwasser Film God Posts: 4441 From: prospect ky usa Registered: Mar 2005 posted 05-24-2006 09:02 AM                        ORC-era metal gears were not hardened properly. The older and newer metal gears seem to last indefinately, like old Westrex gears. Louis  |  IP: Logged Steve Guttag We forgot the crackers Gromit!!!

One thing though, look at the age of them in comparison to the tin cans you have in the other screens... Those Centurys have had minimal maintenance in their hard lives. I wonder what state the shakeys would be in if they were that age and had done that much work?  |  IP: Logged Tommie Evans Expert Film Handler Posts: 116 From: Birmingham, West Midlands, UK Registered: Sep 2004 posted 05-29-2006 08:58 PM                     quote: Pete Naples One thing though, look at the age of them in comparison to the tin cans you have in the other screens...
