Re: Air-cooled VW to 8" Motor adaptor plate Question

Hello Mike,

I just went to measure the pressure plate hole in my flywheel to the edge of
the fly wheel. It now reads 0.29 inches. The edge of the pressure plate is
right at the edge of the flywheel. So to go more, a person would have to
bolt on the pressure plate and turn down both together.

I would say that another 0.125 inch off may work. The bolt holes on my
large flange coupler on the motor is only 0.0626 from the edge of the
coupler and it held up for over 30 years now.

Roland
