Fitting a drive plate

[dan9487]

I'm trying to fit a drive plate to a fly wheel which doesn't have the correct bolt hole spacings on it.
Obviously it needs to be perfectly centered so does anyone have any recommendations for drilling/aligning it or should I just be buying one with the correct holes already drilled?

I get a skim done on a lathe so the drive plate drops in perfectly concentrically and drilling the holes then is easy.
I have tried just making an alignment stub in the past, like a clutch alignment tool, but it proved to have too much run out

It has to be concentric with the shaft, not the flywheel. So you need a dummy shaft to locate in the flywheel spigot and with the correct diameter for the drive plate spline. Think this is something I would get a machine shop to do unless you are really confident!

A good machine shop will have no problems doing the drilling......however, if the one you have now doesn't have the correct holes it probably is not the one for the engine. These should be matched with the correct springs, thickness of plate ect.

Best alternative is buy the correct one!
