3 piece wheel maintenance.
After every race you should clean and inspect wheel spokes for any damage and at a very minimum visually check for cracks.
You should on a yearly basis remove the magnesium centre from your wheel for crack testing and repainting also replacing the fixing bolts. The spun alloy rims should not need any maintenance apart from a visual inspection, unless they have been damaged.
Do not use uncoated fixing bolts, the bare metal of the bolt can react with magnesium when moisture is present. We use 12.9 socket cap screws, bright zinc plated.
We offer a service to blast clean with aluminium oxide, crack test, rechromate and paint your centres.
Enquire for prices.
Should you consider chromating yourself the chemicals are :-
- Magnesium diachromate (bright orange)
- Manganese sulphate (white)
- Magnesium sulphate (white)
Please check your local area and suppliers regulations for the use of these chemicals.
Add to 1 Imperial gallon of warm water 1 lb of orange chemical and .5 lbs each of the white chemicals stir well to dissolve completely. Plastic or aluminium containers, a plastic dustbin works well for larger items.
