Moby XL, SE-803
Belt Adjustment
Figure 15
The Moby PowerBoard uses a dual stage, belt
driven system to transmit power to the rear
wheel. Belts should be regularly inspected for
adjustment. Both belts are adjusted with two
procedures.
Tighten both belt adjusters on either side of the
frame (
Fig. 15
) in equal increments until the
small belt has approximately ½ inch of play when
measured between the pulleys.
Next, loosen the rear axle lock nut, using a
17mm wrench or socket. Adjust the tension in
the larger belt by using the rear wheel adjusters
located at the rear of the frame, behind the wheel
(
Fig. 16
). The belt should have approximately ½
inch of play. Make sure that the wheel is lined up
in the center of the frame.
After adjustment, test ride the unit for a short
distance to ensure that the belts ride in the
center of their pulleys. If they tend to ride on one
side of the pulley(s), adjust the opposite side
adjuster until the belt centers on the pulley, being
careful to maintain the correct belt tension.
