Front Wheel Disassembly

 Remove front wheel (see Front Wheel Removal).

187 Caution: Do not allow the wheel to rest on the brake disc, as this may damage the disc. Support the wheel on

wooden blocks, equally spaced around the rim, such that the brake disc is raised above ground. Lay the wheel on its side while supporting the wheel on wooden blocks to prevent damage to the brake disc.

 Remove and discard the seals and the bearing circlip (If applicable).

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 is suitable protective apparel is not worn.

Caution: To prevent wheel damage and to aid bearing removal, always apply forces 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.

 Using a suitable pin punch, through the centre of the wheel, drift out the wheel bearings. Collect the centre sleeve.

Front Wheel Assembly

 Using a suitable tool, ensuring the tool seats on the outer race of the bearing only, evenly and progressively drive the new wheel bearings into the wheel hub up to the stop. Grease the inner spacer with red grease.

 Fit a new Circlip (if applicable).

 Lubricate and fit new seals to the front wheel. Lubricate the seals knife-edge with grease.  Fit the front wheel (see Font Wheel Installation).

Rear Wheel Disassembly

 Remove rear wheel (see Rear Wheel Removal).

 Place the wheel on wooden blocks to prevent dame to the brake disc.

Caution: Do not allow the wheel to rest on the brake disc, as this may damage the disc. Support the wheel on wooden blocks, equally spaced around the rim, such that the brake disc is raised above ground. Lay the wheel on its side while supporting the wheel on wooden blocks to prevent damage to the brake disc.

 Remove and discard the seals and the bearing circlips (if applicable).

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 is suitable protective apparel is not worn.

188 Caution: To prevent wheel damage and to aid bearing removal, always apply forces 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.

 Using a suitable pin punch, through the centre of the wheel, drift out the wheel bearings. Collect the centre sleeve.

Rear Wheel Assembly

 Using a suitable tool, ensuring the tool seats on the outer race of the bearing only, evenly and progressively drive the new wheel bearings into the wheel hub up to the stop. Grease the inner spacer with red grease.

 Fit a new Circlip (if applicable).

 Lubricate and fit new seals to the rear wheel. Lubricate the seals knife-edge with red grease.  Fit the rear wheel (see Rear Wheel Installation).

Wheel Inspection

 Place the jack under the frame so that the front or rear wheel is off the ground.

 Spin the wheel lightly, and check for roughness or binding.  If roughness or binding is found, replace the hub bearings.  Visually inspect the front and rear axles for damage.  If the axle is damaged or bent, replace it.

Spoke Inspection

 Check that all spokes are tightened evenly.

 If spoke tightness is uneven or loose, torque the spoke nipples evenly.

 Spokes should be tighten until; when struck with a tuning fork they emit a clean note, minimum torque setting is only the lower limit.

Torque minimum: Spoke Nipples: 1.5Nm

 Check the rim runout.

Warning: If any spoke breaks, it should be replaced immediately. A missing spoke places an additional load on the other spokes, which will eventually cause other spokes to break.

Rim Inspection

 Place the jack under the frame so that the front wheel or rear wheel is off the ground.  Inspect the rim for small cracks, dents, bending, or warping.

 If there is any damage to the rim, it must be replaced.

 Set a dial gauge against the side of the rim, and rotate the rim to measure the axial runout [A]. The difference between the highest and lowest dial readings is the amount of runout.

 Set a dial gauge against the outer circumference of the rim, and rotate, the highest and lowest dial reading is the amount of runout.

189  If rim runout exceeds the service limit, check the wheel bearings first. Replace them if they are

damaged.

 If the problem is not due to the bearings, correct the rim warp (runout). A certain amount of rim warp can be corrected by recentering the rim on spoked wheels. Loosen some spokes and tighten others within the standard torque to change the position of different parts of the rim. If the rim is badly bent, however, it must be replaced.

Rim runout (with tire installed)

Standard: Axial 0.5mm Radial: 0.8mm Service Limit: Axial 2mm Radial: 2mm

Axle Inspection

 Place the axle in V blocks that are 100mm [A] apart, and set a dial gauge on the axle at a point halfway between the blocks.

 Turn the axle to measure the runout. The difference

between the highest and lowest dial readings is the amount of runout.

 If runout exceeds the service limit, replace the axle.

Axle Runout/100mm

Standard: 0.1mm or less Service Limit: 0.2mm

Wheel Balance

Note: To improve stability and decrease vibration at high speed, the front and rear wheels must be kept balanced.

 Check and balance the wheels when required, or when a tire is replaced with a new one.

Balance Inspection

 Remove the wheel (see this chapter).

 Support the wheel so that it can be spun freely.

 Spin the wheel lightly, and mark [A] the wheel at the top when the wheel stops.

 Repeat this procedure several times. If the wheel stops of its own accord in various positions, it is well balanced.  If the wheel always stops in one position, adjust the

wheel balance.

190  If the wheel always stops in one position, provisionally attach a balance weight [A] on the rim at the

marking.

 Rotate the wheel ¼ turn [B], and see whether or not the wheel stops in this position. If it does, the correct balance weight is being used.

 Attach a balance weight [A] loosely to the wheel rim.

 If the wheel rotates and the weight goes up, replace the weight with the next heavier size. If the wheel rotates and the weight goes down replace the weight with the nest lighter size. Repeat these steps until the wheel remains at rest after being rotated ¼ turn.

 Rotate the wheel another ¼ turn and then another 1/5 turn to see if the wheel is correctly balanced.

 Repeat the entire procedure as many times as necessary to achieve correct wheel balance.  Permanently install the balance weight.

 Firmly press the balance weight on when finished.

Balance weights: 5g 10g 20g 30g

Note: Balance weights are available from Norton Dealers in 5, 10, 20, 30 gram sizes. An imbalance of less than 5 grams will not usually affect running stability.

Do not use four or more balance weight (more than 90 gram). If the wheel requires an excess balance weight, remove and disassemble the wheel to find the cause.

Tyre

Air Pressure Inspection/Adjustment

 Using a tyre pressure gauge, measure the tyre pressure when the tyres are cold.  Adjust the tyre air pressure according to the following specifications, if necessary.

Air Pressure (when cold) Front: 2.34bar (34psi) Rear: 2.62bar (38psi)

Tyre Inspection

Note: As the tyre tread wears down, the tyre becomes more susceptible to puncture and failure. An accepted estimate is that 90% of all tyre failures occur during the last 10% of tread life (90% worn). So it is false economy and unsafe to use the tyres until they are bald.

 Remove any imbedded stones or other foreign particles from the tread.

 Visually inspect the tyre for cracks and cuts, replacing the tyre in the case of bad damage. Swelling or high spots indicate internal damage, requiring tyre replacement.

 Measure the tread depth at the centre of the tread with a depth gauge [A].  Take measurement at several places as the tyre may wear unevenly.  If any measurement is less than the service limit, replace the tyre.

191

Tread Depth

Front: Standard: 3.5mm

Service Limit: 2mm (legal Limit UK 1mm) Rear: Standard: 5mm

Service Limit: 2mm (Legal Limit UK 1mm)

Note: To ensure safe handling and stability, use only the recommended standard tyres for replacement, inflated to the standard pressure.

 Check and balance the wheel when a tyre is replaced with a new one.

Tyre Removal

Caution: Do not lay the wheel on the ground with the disc facing down. This can damage or warp the disc. Place blocks under the wheel so that the disc does not touch the ground.

 Remove the wheel from the motorcycle (see this chapter).  To maintain wheel balance, mark the valve stem position

on the tire with chalk so that the tire can be reinstalled in the same position.

 Take out the valve core to let the air out.

 When handling the rim, be careful not to damage the rim flanges.

 Lubricate the tyre beads and rim flanges on both sides with a soap and water solution or rubber lubricant. This helps the tyre beads slip off the rim flanges.

Caution: Never lubricate with mineral oil (engine oil) or gasoline because they will cause deterioration.

 Break the beads away from both sides of the rim with a bead breaker.  Protect the rim with rim protectors , pry the tyre off.

192

Tyre Installation

 Check the tyre rotation mark on the front and rear tyre and install it on the rim accordingly.

Note: the direction of the tire rotation is shown by an arrow on the tire sidewall.

 Position the tire on the rim so that the valve is at the tire balance mark (the chalk mark made during removal or the yellow paint mark on a new tire).

 Check and adjust the air pressure after installing.

Hub Bearings (Wheel Bearings)

Bearing Removal

 Remove the wheel, take out the following:  Collar(s)

 Coupling (rear hub)  Grease Seals  Circlip

 Take the bearings out of the hub, using bearing remover.

Caution: Do not lay the wheel on the ground with the disc facing down. This can damage or warp the disc. Place blocks under the wheel so that the disc does not touch the ground.

Bearing Installation

 Before Installing the wheel bearings, blow any dirt or foreign particles out of the hub with compressed air to prevent contamination of the bearings.

 Replace the bearings with new ones.  Press in the bearings until they bottom out.

Note: Install the Bearing so that the marked side or sealed side faces out.

 Install:

o New Circlip o Collar

o Right Bearing o Left Bearing

 Replace the grease seals with new ones.

 Apply high temperature grease to the grease seal lips.

193

Bearing Inspection

 Since the hub bearings are made to extremely close tolerances, the clearance cannot normally be measured.

Caution: Do not remove any bearings for inspection. If any bearings are removed, they will need to be replaced with new ones.

 Turn each bearing in the hub back and forth [A] while checking for play, roughness, or binding. If bearing play, roughness, or binding is found, replace the bearing.

 Examine the bearing seal [B] for damage or leakage.  If the seal is damaged or is leaking, replace the bearing.
