Sidewinder third bearing mount

[Bill Peck]

If the ones you find are really expensive, let me know. I built a bunch of them back in the Yamaha days. Macs never had them originally. The clutches were not so big and heavy at that time. It wasnt until the Horstman Disk clutches came out in the early 80's did the crank breakage become a more serious problem. Or a clutch flying off and hitting someone.

The first generation Horstman was big bulky and a very heavy three disk clutch. I had one of the originals. It was just too much to risk breaking a crank at the time. Somewhere around here are probably most of those old parts. That one was for a Mc 92 without keyway and left hand threads. There was also no provision for a third bearing support yet either.

Thanks. Let me see what I can find.
