| After
a period of time & mileage tyres will be replaced. This is the best
occasion to check the valve. It is recommended to replace it; many
tyre & wheel specialists have made a routine of this. |
|
|
|
| Clean
the valve seat and -hole thoroughly after removal of the valve |
|
|
| Apply
a layer of ALgrease in the valve hole and the outer and inner side
up to 2 centimetres in diameter around the valve hole |
|
|
| Before
installing the valve apply some ALgrease on the shaft and base where
the rubber ring is located |
|
| To
avoid loss of air by improper fitment or corrosion, Alcoa wheels
should be fitted with chrome or nickel-plated valves that meet high
standards and that are specially designed for Alcoa wheels. Alcoa
valves have 14 and 16 mm hex nuts; older US made wheels used 5/8"
hex nuts for the valves. |
|
| Install
the valve gently and do not over torque: the recommended torque
is 9 to 16 Nm |
Do
not use any other lubricants that are water-based or contain heavy
metals. Two types of valves cover almost all wheels. The most common
valves used on Alcoa's latest wheels are the 60MS27N for 8.25 &
9.00 and the TR 542 for all 11.75, 13.00 and 14.00 wheels. For further
details see technical. In
case of doubt contact your local dealer, distributor
or Alcoa Wheels
Avoid using sharp tools and / or excessive force that could cause scratches or dents in the surface. Uneven or damaged surfaces can lead to leakage. Fine sandpaper, steel wool or a soft wire brush will help you to clean the area without harming the surface
