Silent Film Operation And; Adjustments - Eiki ESL SERIES Service Manual

B. Adjustments
1. Take-Up Torque
The take-up arm belt must be kept clean with the blue side of the belt positioned towards
the pulleys. Avoid any oily substances on the belt. Clean the belt with lsoprophyl Alcohol.
The take-up tension is adjusted by increasing or decreasing the belt tension with the
adjustment screw (13). This tension should have a range from approximately 90 grams to
150 grams, depending on the reel size. Torque in excess of 150 grams should not be
permitted on small film reels. Under normal operation where small to medium size reels are
used, the tension screw should be adjusted to where it barely makes contact with the
tension spring (1 mm to 3mm). Clockwise adjustment increases the take-up torque. Counter
clockwise adjustment decreases the take-up torque.
2. Take-Up Clutch Mechanism
The take-up clutch mechanism requires no lubrication. The clutch cam, clutch cover and
drive gear should be kept clean and free from dirt. A small amount of silicone oil on the
drive pulley shaft is sufficient.
