ABSTRACT:
A dust cap is mounting on the front wheel of a racing car to prevent contamination of the corresponding wheel bearings. The dust cap is threaded for engagement with corresponding threads formed on the wheel hub to allow the dust cap to be quickly removed or installed. An O-ring housed in a groove formed in the wheel hub engages the outer circumference of the dust cap to affect a seal between the dust cap and the wheel, and to restrict rotational movement of the dust cap and prevent an unintentional disengagement of the dust cap from the wheel. The closed end of the dust cap is formed with hexagonal flats having a spacing that fit the wrench used for engagement of the nut holding the wheel on the axle spindle, thus reducing the time needed for removal of the front wheel, particularly during pit stops in a car race.
