New Swingarm Busings

Here is an area that provided several learning opportunities (I am getting tired of saying this). It started with the removal of the old silent blocks which is detailed in my “Rebuilding the Swingarm” post. New bushings were pressed in with the only observation being that you should press on the large diameter of the bushings to get them in. I accomplished this on a small hydraulic press using a couple of large washers to provide clearance for the inner tube.

The washer mounted for clearing the center tube. 
One was put on the opposite end before moving to the second bushing. 

A small press was used to push in the bushings. 

My first learning opportunity was that new bushings should have been fit before painting the frame. The new bushings were a bit too long and removed some paint upon installation. Lesson learned. I filed a bit off of the silent block small diameter tubes which let them slide into place. The frame is too rigid to press apart for the assembly to slide in. (Lesson two learned).  The third lesson is that Cadmium plating adds enough thickness to the spindle diameter that it will not go in. I filed it on a lathe until it was a tight slip fit. It went together well and was tightened until the silent blocks flexed for swingarm movement and not slippage on the spindle shaft. New shocks were fit, completing the process.  Now it’s on to the steering head and tapered roller bearings.
