REAR WHEEL INSTALLATION
300, 4.0 AND 400 SERIES SCOOTERS
The order of this installation is very important. Start with the chain pushed
over the frame so it can be placed on the large sprocket after the wheel is in
place.
If your scooter has a rear brake install it on the left side axle. Be sure
the chain is mounted on the large sprocket on the right side of the hub.
Push the wheel with the larger chain guard all the way forward in the frame.
Work the chain onto the small drive sprocket on the motor.
When the chain is in place on both sprockets, pull the wheel back in
the frame until the chain slack is completely removed.
Install the left and right side chain tension adjusters and the axle
nuts, but do not tighten completely at this time. Chain tensioners are
mounted on the outside of the frame.
Adjust the chain tensioners for proper chain tension (5-6mm or about
1/4” slack), then install the smaller chain guard on the right side of the
frame, over the motor gear and chain with its fixing screw.
If your scooter has a rear band brake attach it and the brake cable
hanger by inserting the 4mm Allen bolt through the frame. Mount the
band brake arm on the bolt first, then the rear cable hanger. Hold the
nut using an 8mm wrench and tighten the bolt with a 4mm Allen key
(or Phillips screwdriver), and completely tighten both right and left axle
nuts at this time.
If your scooter has a rear band brake attach the brake cable by first
making sure the brake cable is inserted through the adjusting barrel
on the rear cable hanger. Then slide the spring over the brake wire.
Thread the brake cable through the hole in the cable pinch bolt. Next
insert the pinch bolt (with cable) through the brake actuator arm, start-
ing from the back side of the arm so that the nut can be tightened from
the outside. Place the washer over the pinch bolt and install the nut.
Hand tighten the nut only at this point.
If your scooter has a rear band brake adjust the brake cable by pulling
and holding it taut with pliers through the pinch bolt, push the brake
actuator arm forward along the wire and then tighten the cable pinch
bolt using a 10mm wrench. Immediately test the brake cable adjust-
ment by squeezing the brake lever. When the brake is fully applied it
should not touch the handlebar, and the wheel should spin freely when
you release the brake lever. It may take you 2 or 3 attempts to make
this adjustment.
