page for the number of balls in each location.)
Assembly and adjustment
1. Winding Coupler (4)
1.1 With the shutter completely wound {winding stopper engaged) , the winding
coupler should be positioned as shown (10° ± 4.5° off the body centerline).
1.2 Visual angle check: the: line formed by the axis of the winding shaft and the
mounting screw for SW5 is the maximum limit (14.5°) for the coupler.
2. Spool Torque
2.1 Lubricate the spool unit fiber friction washers with a mixture of FLA and PO A2
grease. (7:3)
2.2 Exercise the spool mechanism 30 to 50 times. Then measure the torque.
Std: 110 - 150 gcm
3. Post Assembly Checks
3.1 After the spool unit is installed in the camera the correct tension measured at
the spool circumference (equivalent to spool friction torque) 170 to 230g.
3.2 Adjust the thrust play to 0.1 to 0.3mm by changing washer (15).
4. Adjust winding shaft thrust play to 0.05 to 0.15mm by changing washer (2).
