Cam Tube Service Kit Installation
Hendrickson released guidelines for installing the cam tube service kit on compatible axle/beam weldments.
The cam tube service kit can be installed on compatible suspensions from the inboard side of the wheel. It’s not necessary to remove the hub, tire/wheel assembly or brake drum.
If necessary, remove the brake adjuster from the camshaft and remove the existing cam tube. Using #2EP NLGI chassis lube, lightly lubricate the internal seals and bushings on both ends of the new cam tube assembly.
From the inboard side of the suspension beam, slide the new cam tube assembly into the camshaft through the mounting hole in the suspension beam and into the spider. (See Figure 1.) Make sure the end of the cam tube without the decal goes onto the camshaft first. Rotate the cam tube so the grease fitting is accessible (either pointing downward or to the rear) when the drums are installed.
It’s important not to weld or otherwise fasten the cam tube assembly to the spider. The assembly simply slip fits into the spider, according to the company.
Next, arrange the two cam tube brackets back to back and slide them onto the end of the cam tube assembly. Make sure to slide the cam tube brackets onto the cam tube until they contact the suspension beam.
Rotate the cam tube bracket so its holes align with the holes or slots in the suspension beam. If necessary, rotate the cam tube so the grease fitting is accessible when the drums are installed.
