13.3 Inspection
The motor/gearbox/wheel assembly is mounted securely to the motor, which should be securely
attached to the side frame.
Check the tyre for excessive wear and the wheel for signs of damage.
Check for rim-rock which will indicate worn bearings and/or stub axle. Maximum allowable is 5mm
total.
Check for end-float which will indicate worn thrust washers. Maximum allowable is 3mm.
Check that the free-wheel mechanism engages and dis-engages freely and that the drive dogs
do not have rounded corners.
Check the drive securing bolt in the end of the drive shaft is tight and the tab washer is bent up
for security.
Check the motor loom for damage and that the plug wiring is secure.
Check for unusual noises such as whining or rubbing which might indicate that the solenoid brake
is touching the cowl.
Move the joystick around the quadrant and check that when released it self-centres and the
brakes operate.
An audible click will be heard from each motor when the brakes are applied and released.
Raise the rear of the powerchair and support on suitable stands. Engage the drive mechanism
and move the joystick around the quadrant to simulate forward, reverse and turning. Observe the
wheel rotation to ensure it mirrors joystick movement and check for any wheel/tyre distortion.
13.4 Power System Removal
If it is required to remove the complete drive assembly as one unit the following procedure applies.
Support the rear of the powerchair on suitable stands and disconnect the motor wiring loom from
the main loom. Using 7/16 AF spanners release the four nuts/bolts which attach the mounting
plate to the side frame. Withdraw the bolts and remove the assembly.
13.5 Power System Replacement
Replacement is a straightforward reversal of the above procedure. The attachment nuts and
bnolts should be renewed and tightened to a torque of 35 lbs/ft (47Nm).
