Wheel Hose Fitment
Each wheel hose has had a tyre valve hose tail fitted. A straight fitting for the
inner wheel and a 180 degree ‘U’ Bend fitting for the outer wheel. The wheel
hose assemblies are made to length to suit the wheel size of the vehicle.
a. All TractionAir hoses are measured overall outside end of one hosetail
straight to the outside end of the other hosetail.
b. When fitting TractionAir to alloy rims, ensure the hose does not ride
against the alloy wall of the rim as the hose will wear the rim wall away.
Only hand tighten the tyre valve hose tails on to the tyre valve stems. Over-
tightening will damage the rubber washer designed to seal on the “sharp” face
of the valve stem.
To fit the wheel feed hose; attach the 45 degree hose tail to the nipple
(TAAG0207) fitted to the side of the Rotator. Run the hose up to the elbow
adaptor (45 deg TAAG450407 or 90 deg TAAG900407) as mounted to the tee
between the wheels. This hose is made of sufficient length to allow for axle
travel (up and down). A standard 22.5” truck wheel requires a hose length of
810mm. The hose should sit approx. 60mm from the outer side wall of the tyre
to inside of hose. WARNING - excessive length here and the hose is likely
to get caught on obstacles. However, remember to allow for “walk out” in the
suspension for those trucks fitted with Hendrickson walking beam and other
mechanical suspensions. For these suspension set-ups, the tee may need to be
fitted further out from the chassis than on trucks fitted with air suspension.
