Balance wheel assembly referring to equipment manufacturer’s instructions. corrosion and tyre imbalance.

It is essential that the wheel is located by the centre Aluminium wheel rim bead seats should be cleaned hole NOT the stud holes. To ensure positive wheel using a non-abrasive cleaner to remove the mounting location the diameter of the locating collar on the lubricants and old rubber. Before mounting or machine shaft must be 112.80 to 112.85 mm, 4.441 to demounting a tyre, bead area should be well 4.443 in. This diameter will ensure that the collar fits lubricated with a suitable tyre lubricant. correctly within the centre hole of the wheel.

Where possible always use the vehicle wheel retaining nuts to locate the wheel on the balancer, to

avoid damaging the wheel. If this is not possible, the locating nuts must be of a similar pattern to the

original wheel nuts. The use of conical type wheel nuts for this purpose may damage the surface on alloy wheels.

Cleaning

Wash the aluminium wheels using a suitable wash and wax concentrate correctly diluted and rinse with cold clear water. DO NOT use abrasives or aluminium wheel cleaners containing acid, as they will destroy the lacquer finish.

making further inflation impossible, and carry out following procedure.

Tyre changing

Use only tyre changing equipment to mount or demount tyres, following the equipment manufacturer’s instructions. DO NOT use hand tools or tyre levers, as they may damage tyre beads or the wheel rim.

Puncture repair

Remove punctured tyre from wheel and repair using a combination service plug and vulcanising patch. Always follow manufacturer’s instructions when using a puncture repair kit.

Only punctures in tread area are repairable, DO NOT attempt to repair punctures in tyre shoulders or sidewalls.

Do not attempt to repair a tyre that has sustained the following: bulges or blisters, ply separation, broken or cracked beads, wear indicators visible and punctures larger than 6 mm diameter.

• CAUTION: Do not use tyre sealants that
• are injected through valve stem to repair
• punctured tyres, they may produce wheel

1. Install a new valve assembly.
2. Ensure wheel and tyre is adequately lubricated.
3. Mount tyre in normal manner. Inflate tyre and at same time apply hand pressure to area around valve to aid seating over valve first.

• NOTE: Stop inflation immediately if tyre
• seats opposite valve, as this will result in
• valve being blocked by tyre beading,

4. Deflate tyre, unseat and rotate it around the rim until valve is in line with that part of tyre which seated initially. This part of beading having seated over hump previously will automatically seat first when tyre is re-inflated.
5. Inflate tyre to seat beads correctly, finally inflate to correct pressure.
