REAR WHEEL


REMOVAL

WARNING



CAUTION



NOTE




Place the motorcycle on its center stand.
Remove the center cap and cotter pin.  Loosen the wheel nut, but do not remove it.

Info: The rear wheel mounting nut is 27mm.

Loosen the eccentric bearing carrier pinch bolt and turn the carrier counterclockwise until it stops to obtain maximum chain slack.
Remove the chain from the rear sprocket and place it on the outside of the sprocket.
Rotate the eccentric bearing carrier to its rearward most (maximum chain slack) position.



Remove the wheel nut, shim and axle center collar.

Tap the axle with soft hammer and push the axle in until it clears the wheel.

Attach tape to the wheel rim, edge of the spindle and brake caliper to avoid damaging the wheel.

Remove the wheel from the drive pins, then angle it to the right and pull it backward to go between the brake disc and muffler.

CAUTION





Then, as the wheel reaches the hub, angle it to the left and pull it out backward as shown.

CAUTION




Page 13-4

INSPECTION

Wheel rim runout

Check the rim runout by placing the wheel in a truing stand.
Spin the wheel slowly and read the runout using a dial indicator.

SERVICE LIMITS
RADIAL RUNOUT:2.0 mm (0.08 in)
AXIAL RUNOUT:2.0 mm (0.08 in)

NOTE





wheel Balance

CAUTION




NOTE





Remove the dust seal from the wheel.
Mount the wheel and tire assembly in an inspection stand.
Spin the wheel, allow it to stop, and mark the lowest (heaviest) part of the wheel with chalk.
Do this two or three times to verify the heaviest area.  If the wheel is balanced, it will not stop consistently in the same position.

To balance the wheel, install wheel weights on the highest side of the rim, the side opposite the chalk marks.  Add just enough weight so the wheel will no longer stop in the same position when it’s spun.
Do not add more than 60 grams to the rear wheel.



Drive pin hole

Check the drive pin holes for the damage.

Inspection and replacement of the drive pin: turn to page 13-11.


Page 13-5

INSTALLATION

WARNING




CAUTION





Install the rear wheel in the reverse order of removal.

Clean the wheel and spindle mating surface.
Align the index marks and install the wheel hub over the drive pins.



Insert the axle in the wheel hub, making sure the splines are correctly aligned.

Tap the axle with soft hammer to seat the axle securely.

Turn the eccentric bearing carrier counterclockwise until it stops.
Install the drive chain onto the rear sprocket.

Clean and apply clean grease to the axle threads.

CAUTION






Install the axle center collar, shim and wheel nut.
Tighten the wheel nut to the specified torque.

TORQUE: 120 N•m (12.0 kg-m, 87 ft-lb)

Install a new cotter pin and cap securely.

Apply the rear brake several times and check for free wheel rotation when released.

Adjust the drive chain slack (page 3-12).


Page 13-6


SPROCKET

REMOVAL

Turn the eccentric bearing carrier to loose the drive chain, then remove the chain from the sprocket.

Remove the sprocket mounting bolts and the sprocket.




INSTALLATION

Install the sprocket by using the bolts and nuts.

TORQUE: 43 N•m (4.3 kg-m, 31 ft-lb)

Remove the axle to the left side.


Page 13-7


Unstake the eccentric bearing carrier lock nut and remove the nut.
Remove the lock washer and side collar.

Info: The nut is 46mm.  A 1-13⁄16" socket is exactly the same size but easier to find and cheaper.



Remove the brake caliper mounting bolts.
Swing the brake caliper from the brake disc while holding it with a piece of wire or something suitable.



Remove the spindle.
Remove the final driven flange assembly and remove the drive chain from the sprocket.



Remove the snap ring and brake disc guard plate.
Remove the eccentric bearing carrier from the swingarm.


Page 13-8


INSPECTION

Bearing
Turn the inner races of the ball bearings with your finger.
The bearing should turn smoothly and quietly.

Also check that the bearing outer races fits tightly in the eccentric bearing carrier.
Check the right bearing needle rollers for obvious signs of wear.

Remove and discard the ball bearings if they do not turn smoothly, quietly, or if they fit loosely in the eccentric bearing carrier (page 13-9).

NOTE




Replace the needle bearing if it is damaged.




Damper
Separate the driven flange cover with the sprocket from the flange.

Check the driven flange damper for damage.

INSPECTION

Inspect the following parts:

Inspect all the other parts for wear or damage.

Measure the spring free length.

SERVICE LIMIT: 148.3 mm (5.84 in)


Page 13-16



Mark the 10 mm position on the damper rod as shown.
Place the damper rod on a scale and measure the force required to compress the damper to the 10 mm (0.4 in) mark.

COMPRESSION FORCE: 15 - 20 kg (33.1 - 44.1 lb)

If the force required is less than 14.9 kg (32.8 lb), gas is leaking.
Examine the damper rod and replace the damper unit if it is bent or scored.



SHOCK ABSORBER DISPOSAL PROCEDURE

Center punch the damper case to mark the drilling point, approximately 15 mm (0.59 in) from the top surface.
Wrap the damper unit inside a plastic bag.

Through the open end of the bag, insert a drill motor with a sharp 2-3 mm (5/64 - 1/8 in) drill bit.

WARNING



Hold the bag around the drill motor and briefly run the drill motor inside the bag; this will inflate the bag with air from the motor and help keep the bag from getting caught in the bit when you start.
