flywheel machining
I hope someone can help me with a small problem Iam having;
I intend to machine the face of my flywheel, but have not been able to remove the 3 tapered pins that locate the clutch housing .
Has anybody tackled this job? if so how did you get the pins out?
If the pins cannot be removed, would I be ok machining only where the clutch plate sits?
Many thanks for your help

You will have to take off the same ammount from where the pressure plate sits as where the friction plate sits or else you will alter the spring
pressure and will get clutch slip. Cant you drill the pins out and fit some new ones when you have finished.

I'm sure I've got one, just don't know where I've put it

Flywheel
Hi
Normally, a good pair of mole grips well pull them out, they are only an interference fit. If they get badly damages you can replace them. You do need
to skim the whole area or you will lose some of the clutch plate thickness in to the machined area.
Hope thats of some use.

Thanks for the replies, I'll try a bit more brute force and ignorance on them and then if that fails I guess its out with the drills.
Thanks again.

I had mine machined at an engine builders and they didn't remove the pins. They machined around them.

Here is an update;
The pins are harder than the devils forehead , so they cannot be drilled out.
I tried drilling a small hole from the rear so I could knock them out with a pin punch, no chance, they are in far too tight.
I have come to the conclusion that Mad Scientists suggestion (thanks for that) is the only option. On with the machining then.
Thanks guys

Please be careful when machining flywheels, IMHO it is best left to the experts. I have seen flywheels explode before now, and it is very messy......
Dont just build it.....make it!

Grip dowel in vice very firmly and then whack flywheel with copper mallet or similar to pull dowel out. They are always in tight but will always come
out. File dowel round again after extraction, they will be ok to reuse, if not they are readily available from Ford for a few pence each.
Pinto flywheel is flat across the face so you are right, dowels have to come out for machining. - "Mad Scientist" - yours wasn't
done properly.
Unless you are having flywheel dynamically balanced afterwards do nothing other than skim across face.
