Option 1
OS Drive Washer OSM 45208010
Standard Flywheel
Associated Clutch Nut 2312 (Drilled and tapped to ¼-28
Option 2
Get Crankshaft ground by machinist to 7mm Then use standard collet like Associated part 7618 and standard flywheel
Option 3:
Get crankshaft ground to 7mm by machinist, then use BuKu 34mm brass flywheel and BuKu BBK shoes with standard springs.”
I have everything to do option 1. I have the os drive washer and a drilled and tapped associated clutch nut for my 40scx. My question is by “standard” flywheel, do you just mean a flywheel that isn’t tapered to use a collet? Or will a collet style flywheel still work against the drive washer?
Hey man I got your PM prior to your post being approved. You mentioned using a lathe? If you can, that's the best method so you can make your stuff exactly how you like it. That's how I do mine. As for the flywheel you can either use a collet style to fix it to the crankshaft (ideal) or you can use a drive washer to drive the flywheel with friction. While this WILL work, be aware that this is my first setup I tried and the "D" shaped "key" on the crankshaft was not sufficient. The crank eventually just spun through the flywheel and stripped it out while starting the engine on a starter box.
Edit: This was with my O.S. .62-V engine. I dont know what type of "key" your engine uses.
