WARNING: Do not use excessive pressure to seat a reluctant tire bead. Tires and wheel rims can
suddenly explode if inflated beyond recommended pressures. A tire should seat with normal
pressures when lubricated. If the tire does not seat, deflate it, check that the inner tube or rim flap
are not captured under the tire bead, especially near the valve stem, and lubricate the bead again
before inflating.

WARNING: For your own personal safety, tires and tubes must be correctly matched to wheel rims.
Mismatching tires, tubes and rims may result in damage to the tire bead during mounting or may
allow the tire to slip on the rim, possible causing tire failure. In addition, using tires other than
those specified may adversely affect motorcycle stability. Tire sizes are molded on the tire sidewall.
Tube sizes are printed on the tube.

When the tire has been mounted and seated correctly, check balance of the wheel/tire assembly, and if
necessary, rebalance using spoke weights.

Dismantling and Reassembling the Wheel Hub (with the wheel removed)

The required tool is mandrel 345-324-3 for removing the roller bearing cup.

To dismantle the wheel hub:
1. Loosen locknut, undo the seal nut and remove the left-hand distance bushing.
2. Insert the mandrel on the wheel axle on the splined hub side and press out the end roller bearing,

intermediate bushing, second roller bearing cone and right-hand distance bushing.

3. Using mandrel 345-324-3 press out the thrust washer and the roller bearing cup.

Wash and inspect the dismantled parts. Change any defective parts.

Reassemble the wheel hub as follows:
1. Fit the thrust washer and the right-hand distance bushing into the hub, inserting the shoulder of the

bushing into the thrust washer groove.

2. Pack the bearings with wheel bearing grease, and press in the bearing and bushings in the reverse

order they were removed.

3. Press the rubber collar into the oil seal nut arranging it so that the oil catching edge and the spring

are inside the nut.

4. Insert the left-hand bushing into the seal nut from the side facing the bearing, and torque the nut to

the specifications to properly seat the bearing races.

Tightening torque: 12 ft lb. / 16 Nm
1. Turn off the nut by 1/6 to 1/8 of a revolution and lock with a locknut.

After reassembling, check the bearings for proper clearance, and adjust, if necessary.
To perform this check:
1. Insert the axle into the reassembled wheel hub with an appropriate spacer, and tighten the axle nut
to pull the bearings tight. (rear axle nut).
