Should a flywheel be interference fit?

[JustCallMeOrlando]

Hey all,

Finally bolted my clutch up to my engine, all good....except for the whole, you know, flex plate machined out for some reason.

Here is a pic of what I mean.


The factory flex plate I've got located, but far from what I'd call proper interference. Is this a huge problem? If it is, I'll have to get him to sort it out. In the meantime, it's going in because I need to get it in to do some measurements for other stuff.

Any thoughts appreciated.

Cheers,
Nathan

Definitely don't use it like that!
Flywheels (or anything that spins at a decent speed, ie: more than 1000rpm) must have a good accurate central locating.
It just isn't worth the risk.

plus the vibration youll get from that will be horrible, not to mention would do damage to mains and big ends vibrating that much

Pretty much confirms my initial concerns. I'm going to sort out a locating ring. For some reason he's machined the centre hole out to 48mm as opposed to the factory 42mm of the crank. Grr

a pressed in locating ring would be the easiest and cheapest solution, otherwise welding, machining and balancing are on the cards..

Just start again
