Overview
Trailer wheel ends get the least attention and the most neglect, and a camshaft moving around in a worn spider bushing is exactly the kind of fault that hides out there until the linings tell on it. This Camshaft Repair Kit distributed by FleetPro Parts & Tires rebuilds the S-cam tube on Meritor 16-1/2in Q and Q-Plus trailer axles in TN, TP, TQ and TR types, with the bushings, seals, washers and snap rings that restore camshaft support. Manufactured by Automann to Fleet Standard specifications, we stock these heavily right here in our Hanover Park, Illinois warehouse to ensure lightning-fast shipping for fleets, trailer repair shops, and owner-operators nationwide.
Trailer Wheel Ends Rebuilt Right: The Q/Q-Plus Trailer Axle Kit Advantage
This kit is specific in the way a camshaft kit has to be. It is built for fabricated spiders with metal press-in bushings, the trailer-axle construction where the bushing is pressed into the spider rather than cast in, and it covers the TN, TP, TQ and TR Meritor trailer axle types. Get the spider construction wrong and the bushings in the box will not go where they need to go.
It also ships with the self-tapping 3/8in-16 x 1.83in bolt-on bushing, which is the piece that turns this into a complete repair instead of a partial one. Camshaft radial play at the spider bushing is a common cause of uneven lining wear and brake noise, and taking that play out is what makes the next set of linings wear flat across the shoe. Components are also available separately if only part of the wheel end needs attention.
At FleetPro Parts & Tires, we know a trailer brake job is only right when the camshaft is supported. This Automann kit is a direct replacement for highly searched industry numbers including Meritor KIT8078A, Euclid E9079 and E9079HD.
