When replacing the plastic double gear wheels in the lifting element housings proceed as follows:
Step 1 - Pivot the drive motor console over and detach the drive cable from the pivoting arm. Measure distance "A" (photo 1). Distance must be 284 +/- 1.5 mm. If necessary, adjust the drive cable length by turning the drive cable in the guide pipe.
Step 2 - Install new plastic double gear wheels.
Important Note: In order to prevent damage to the gear wheels, be certain the lifting element fingers are installed against stop in the fully retracted position and are even side to side.
Recheck the drive cable length and correct if necessary. Reconnect the drive cable to the pivoting arm and complete the installation of the drive console.
Step 3 - Check the adjustment of the drive motor friction clutch. Manually operate the roof to a partially open position. This will ensure adequate cable travel. Using a torque wrench on the 21 mm nut, check the friction clutch adjustment. Turn until clutch movement is felt and note reading.
Specification 5.5 N-m (48 in. lbs.). If necessary, adjust by loosening the lock nuts and turning to obtain proper turning torque.
