Lippert Components Coach Step - Manual (Page 4)

SERVICE NOTES
A. Use locktite on any bolts removed and replaced.
NOTE: It is recommended that if the nut is removed and replaced in the field, a liquid “Loctite” locking compound be applied before tightening.
The joint shoulder bolts should be torqued to a minimum of 140 inch pounds.
B. How to adjust cams.
It is not recommended that the tightness of the step be adjusted in the field. Some minor movement of the step is considered normal.
Excessive movement could be an indication of a more serious prob-lem and the bottom cover should be removed and a thorough visual inspection
should be made before any attempt is made to repair the problem by adjusting the cams. The cams are located on the inside of each side plate.
Should it be deemed desirable to adjust the cams, they can be adjusted by loosening the nut on the outside of the side plate, and rotating the cam
and bolt so that they bear more heavily against the step arm. Care should be taken so that both cams are adjusted approximately the same
amount. After adjust-ment, the steps should be operated several times to insure that they are still locking over center. This can be determined by
watching the steps as they complete their deployment. If the steps are locking over center, they will deploy fully and then retract approximately 1/8”
as they lock in place.
C. Installation Precautions
The steps are designed to be mounted to the vehicle by at least 4 bolts. It is recommended that at least 10mm bolts and flange nuts be
used. In no case should the step be welded to the vehicle. This could result in warpage, unreliable performance, and electrical damage to the
module.
D. Service motor as an assembly.
It is strongly recommended that the motor/gear be serviced as an assembly and this is the way replacements are sold. The motor/
gear assembly can be replaced by disconnecting the two pin connector from the module to the motor, removing the “p” clamp holding the wire
harness to the motor mount, removing the ball joint linkage from the gear, the self-tapping screw that holds the ground wire and by removing the 3
bolts that hold the motor mount to the step base. Care should be taken not to disturb the adjust-ment in the length of the ball joint linkage. After
reassembly in the reverse order, no adjustment should be required.
E. Module replacement.
Remove the self-tapping screw holding the ground wire, and disconnect the 4-pin connector to the motor home wiring and the two-pin
connector to the motor. Remove the self tapping screws holding the module in place, and reinstall the new module in the reverse order.
F. Lubrication Coach
Steps are equipped with self-lubricating bushings on the drive assembly and all step joints. No lubrication is necessary. If in extreme
conditions lubrication is deemed necessary a silicon based grease or spray will not harm the bushing material.If any difficulty is encountered
either in the use, installation or service of the steps that is not covered in the service instructions, please call the following number for service or
warranty information. The manufacturer takes no responsibility for unauthorized service or installation procedures.1-866-524-7821.
