4.9.1 CHANGING REAR WHEEL MODEL
The seat to floor height modification can require a change of the rear wheels diameter.
To do this:
a) STANDARD THREADED AXLES :
1. To remove the wheel, unscrew the (A) screw and (B) nut, using a 3/4” wrench;
2. To replace the wheel, use a new nut. Avoid tightening the nut too much, the
wheel might have difficulty to turn (see; figure 24-A).
Figure 24-A : Threaded axle.
With a mid-wheel configuration you always have to change the
front, central and rear wheels at the same time.
NOTE: FOR THE MID-WHEEL PROPULSION
IF 5 INCHES WHEELS:
Install the washer at position A.
IF 6 INCHES WHEELS:
For the (2) rear wheels, install the washer at the
position B and for the (2) front wheels at the
position A.
