M3 - Replace Traversing Drive Motor, Traversing Gear and Traverse Idle Gear
IMPORTANT NOTE: Ensure that the hoist is fully supported at all times. Take great care in
protecting the PCB. There is a tendency to turn the hoist over, thus damaging or breaking the
aluminum standoffs that support the PCB.
1.
The traverse idle gear may be most easily removed by first removing the trolley wheels with
which they mesh – follow the instructions of section M2 to remove the trolley wheels.
2.
Remove the hoist covers as per all of section B1 and section E5, step 2 to safely access the
traverse idle gear.
3.
Use a 2.5mm Allen key to unfasten and remove the M3 screw & nut with the traverse idle
gear.
4.
The traverse idle gear can be replaced now & refastened; the trolley wheels should be now
placed back into position (ref. section M2).
5.
If the traversing drive motor or gear require service, follow steps 1-4 of section M1 NOTING
only to remove the shaft only as much as to disengage it from the one wall of the lift motor
and ensure BOTH batteries with their brackets are removed.
6.
Follow steps 6 - 8 in section E5.
7.
Carefully slide out the traversing motor mounting plate along with the attached gear box
bottom panel until the traversing motor & gear are accessible.
8.
The traversing gear can be removed by pulling it off of the traversing motor shaft by hand.
9.
With the traversing gear removed, the traversing motor can be removed by unfastening the 3
screws with a 4mm Allen key.
10. Follow the previous steps in reverse to mount the new traverse motor & gear and to slide the
gear box plates back into place to fasten them.
11. Reconnect the wire harnesses, airline tubes on the auxiliary board and connect the battery to
test the system before re-assembly.
