To remove the wheel/tyre:
WARNING!
Make sure that the wheelchair controller is turned off before
commencing this procedure.
Please refer to images (Fig. 8.2 - 8.10).
• Remove the colour ring.
• Use a 16 mm AF stud bolt socket to loosen the 3 lug nuts
(Fig. 8.2).
• Jack the base/battery box up and support it using blocks,
(Fig. 8.3).
• Remove the 3 studs and pull the wheel away from the hub.
• Remove the valve cap and let the air out of the tyre by gently
pressing the valve stem with a small screw driver, (Fig. 8.4).
• There are 6 rim studs that must be loosened/tightened in the
number order shown, (Fig.8.5).
• Use a 5.0 mm Allen key to release/tighten the studs. (Fig. 8.5).
• Lift the inner rim off the tyre wall (Fig. 8.6).
• Lift the tyre and tube off the outer rim, (Fig.8.7).
• Gently get a hold of the inner tube just behind the valve.
• Carefully feed the tube out of the tyre, (Fig.8.8).
• Ensure all parts are clean before reassembling, (Fig.8.9).
To refit
• Place the tube inside the tyre and rest the tyre on the outer
rim.
• Align the valve stem with the cut out in the rim.
• Face the valve stem outward.
• Place the inner rim over the tyre, tube and outer rim.
• Align the cut out to fit over the valve stem and match it up to
the cut out in the outer rim, (Fig.8.10).
• Make sure the stud mounts are in line on both rims.
• Tighten the studs in the sequence shown in Fig.8.5, taking
care not to pinch the tube.
• Slowly inflate to the pressures quoted in section 8.1.1 .
• Refit the wheel back onto the motor shaft and fix it safely
with the 3 studs to a torque of 34Nm.
For solid tyres the sequence is the same, just discount the
references to the inner tube and valve.
