one of the few items on the bike that needed real attention was the swinging arm bush and needle roller bearing. it was badly rusted and seized… I checked and the bush is no longer available. I made one out of good quality steel, and case hardened it several times to build up the depth of the hardened layer. I also did a test piece and was pleased that I could not touch it with a file! I have not done case hardening for a LONG time!
I finished welding up the frame and parts. Where I had modified the frame tubes I put an internal tube so it didn’t crush it when I tightened the bolts, then I welded the support bushes on. Then it was off to the powder coaters, along with a big box pf parts to be plated.
Its always stressful pulling an engine apart… you never know what you are going to find! I was really pleased as it came apart. there is no discernable wear on the bore, all bearings are nice and smooth, so its just gaskets, seals, and a new cam chain. I can see why these engines do mega miles, it’s VERY well built!
