The wheels: What an experience.
I won't complain about parts not fitting well because at least they are available. For this project, new brake drums were necessary.

The drums fit the hubs, and the bolts lined up well enough; however, the brake cam, H10 drags on the inner wall of the new drums. Apparently the brake drum casting is thicker than the original drums? Merely shimming the brake plates out caused the completed assembly to be too wide to fit between the lugs on the RFM. The fix was a compromise; 3/32" was skimmed off of each cam bush steady sleeve to regain clearance. Another issue was the new 56 tooth rear sprocket would not bed down on the new brake drum; it required a bit of creative machine work to slightly reduce the outer diameter of the drum flange.

For the upcoming Black Shadow project, we'll further investigate the brake drums and may skim the interior face if there is sufficient thickness.

Here are a few photos:

Part of the joy of this project is finding parts that have been in boxes since the 1960's.

This project is intended as a mechanical rebuild and certainly not a 100 point restoration. This will be a rider.

Fun stuff!

[QUOTE="998cc, post: 653527, member: 9783"] The wheels: What an experience. I won't complain about parts not fitting well because at least they are available.
