Next slide the Super-Drive assembly onto the door
shaft and select a suitable hole in the torque arm
to bolt it to the Super-Drive back plate using the
spacer bush, which should pass through the lower
slot in the Cover back. (Pic 7) The Cover back will
be secured later. The Torque Arm should be
approximately at right angles to the Super-Drive
assembly.
Align the Super-Drive keyway with the door shaft
keyway and fit the key supplied with the package.
Ensure that the two Allen screws are firmly tight
and then tighten the lock nuts. (Pic 8)
If there is no keyway one wall of a hollow door shaft
should be drilled with a 6mm or
1 / 4 -inch drill bit.
The main Allen screw in the boss of the Driven
pulley, should be replaced with the long Allen
screw, which is provided in the kit. The long screw
should be screwed into the drilled hole in the shaft
and tightened against the inside wall of the
opposite side of the shaft. The lock nut should then
be tightened to secure the screw. (Pic 9).
