1972 Norton Rebuild
Just check the last page listed for updates.
Those of you that saw my post about the cam lobes on my Norton going bad due to not being hardened properly can now see the result of this problem. I sent the engine off for a new cam, main bearings, etc, total bottom end rebuild.
It was a long slow winter and as time passed more and more parts came off the bike. Finally I had a bare frame. It would be a shame to put new and rebuilt parts in a frame like that so.........
Frame was powder coated along with all parts that would come off. Wheels are being relaced with new polished stainless steel spokes. Cylinder barrels were powder coated. New lifters will be installed to run on the new cam. The transmission got new seals and a final drive cog change from 19 to 21 teeth.
The reassembly adventure has begun. If you are at all interested in this type of thing here are some pics. I know that there are some bike fans here so I hope you enjoy some of this.
This is the frame with its new powder coat. The frame has pieces of pipe insulation on it to help protect it from clumsy mechanics.
These are some of the parts laid out for re-assembly.
These are the parts that make up the front rubber mount for the engine/transmission sub-assembly. This assembly gets shimmed to .010 or less using the large washer looking rings on the upper left. The black engine mount already has four special rubber doughnuts pressed into it.
This is the new drive cog for the trannny. For those of you that don't know, this is called a pre-unit bike because the tranny and primary drive are seperate from the engine case just like old Harleys. This is a four speed box.
If any of you find this procedure interesting I will post pictures on here as it progresses.
If any of you think that those guys on television can build a chopper in just a few hours or days, you need to get a reality check.
