Removal
1. Turn off the main power switch on the control
panel.
2. Lift the wheelchair chassis and support it on
blocks so that the wheel is off the ground.
3. Remove the hubcap (1), bolt (2) and the three
washers (3 and 4); see figure.
4. Pull the wheel off the shaft. Use puller
304103-99-0 if the wheel is tight; see figure.
Fitting
1. Check that the wheel shaft and rim are
undamaged. Clean as necessary to remove
dirt and rust. Replace damaged parts.
2. Check that the key is firmly attached and
undamaged; fit a new key if necessary.
3. Lubricate the shaft with a thin layer of copper
paste (Würth 0893800x, Art. no.: 1820540).
WARNING
Do not use any type of lubrication in the threaded hole in the
axle or on the bolt.
4. Fit the wheel onto the axle. The use of hand
force only is preferred, but, if need be,
carefully use a rubber mallet, whose head
diameter is no less than 1.5 inches (38 mm), to
ensure that the rim is fully seated upon the motor.
NOTE
Hitting too hard with a rubber mallet could cause damage to
the gear.
5. Mount the three washers (3) and 4) onto the
bolt (2) and secure the wheel. Use a torque
wrench to tighten the bolt to 24 ft-Ibs (33Nm).
Install the hub cap (1). See Fig. 13.
NOTE
The washer (4) should be placed with the most flat side
inwards.
WARNING
The bolt must be used once only. Removed bolt is not
allowed to be refitted.
Other types of bolts or washers are not to be used.
Do not use any other type of thread lock.
