Removal
1. Remove the front wheel (see page 15-10).
Caution: Do not allow the wheel to rest on the brake discs, as this may damage the discs. Support the wheel on wooden blocks, equally spaced around the rim, such that the brake discs are raised above the ground.
2. Place the wheel on wooden blocks to prevent damage to the brake discs.
3. Remove and discard the seals and the bearing circlip.
Warning: Always wear eye, hand and face protection when using a hammer and drift. Use of a hammer and drift can cause bearings to fragment. Pieces of fragmented bearing could cause eye and soft tissue injuries if suitable protective apparel is not worn.
Caution: To prevent wheel damage and to aid bearing removal, always apply force evenly on both sides of the bearing to prevent it from 'tipping' and becoming stuck. Application of uneven force will lead to difficulty in removing the bearing and to a damaged wheel.
4. Using a suitable pin punch, through the centre of the wheel, drift out the wheel bearings. Collect the centre sleeve.
Wheel Bearing Removal
Inspection
Warning: Only remove raised witness marks from within the wheel. Removal of material below any raised areas will reduce the level of interference between the wheel and the bearings. Loss of interference could cause the bearing to become loose in the wheel leading to loss of motorcycle control and an accident.
1. Examine the wheel for any raised witness marks caused by the removal process. Remove any such marks with fine emery paper or a gentle file.
Installation
Note: Refer to the chart below for the correct tool and tool face when inserting bearings. Bearings are inserted by means of a draw-bolt acting on the insertion tool. A support tool is located on the Opposite side of the wheel to the insertion tool and as the bolt is tightened, the bearing is drawn into the wheel.
Insert bearings with the marked or shielded side facing outwards and always fit a new bearing circlip and seals.
Bearing insertion tool | Support tool | |
Left bearing | T3880053 Large face to bearing | 3880070 - T0301 Large face to Wheel |
Right bearing | T3880053 Large face to bearing | 3880070 - T0301 Large face to wheel |
1. Fit the wheel bearings and centre sleeve using the method described opposite.
1. Tool T3880053
2. Fit a new circlip.
3. Lubricate and fit new seals to the front wheel. Lubricate the seal's knife-edge with grease to NLGI 2 specification (we recommend Mobil HP222).
4. Fit the front wheel (see page 15-11).
