I need to put new bolts and washers on a flywheel I am rebuilding that hold the magnets in place. I notice the old washers are 3/32" thick, seams od ball to me. Next what do you use for new bolts, I am thinking grade eight 2 1/2 inches long? Any suggestions would be appreciated. Thanks,
If your bolts are stripped or stretched or otherwise unusable, good original bolts and washers are plentiful. Grade 8 bolts is overkill. Just make sure the holes in the flywheel are clean and the threads on your new old bolts are straight and sharp and you're good to go.
I do, however, recommend that you NOT re-use the aluminum spools out on the ends of the magnets. They are usually brittle. Make or have someone make new brass or aluminum ones. They don't have to be hourglass shaped like the originals, though you can skinny them down in the middle to save weight.
Thanks for the reply, I didn't know if the bolts on a flywheel needed to be stronger because of the weight at 1800 RPM. I notice the venders do not seam to carry flywheel magnet bolts so I will try to find some on e-bay or something.
Jim, what is wrong with the old bolts?
I bought the flywheel on e-bay a few years ago with no hardware and I have a set of magnets and now I want to put it together. I also have a issue with washers, should I use washers from the hardware store or should they be a harder machine variety? Just want to get this part right. Thanks
I'm sure there are several local T'ers who has plenty of those bolts and washers in good condition and would give them to you or sell them very cheap.

I have plenty and they will fit in a small flat rate box.
