Verto flywheel machining specs
Turbo Mini Forums

I have a verto clutch on the 82 998. The flywheel needs to be machined before it gets a new clutch, does anyone have specs on machining? Most Important thing being the depth of the friction surface from the pressure plate mounting surface.

If removing material from the friction surface the same amount should be removed from the mounting posts (pressure plate mounts) to keep the operating geometry/characteristic the same.
Unless it’s an RTS your building then some fettling of post heights is required to get the springs sat in a more optimum position.

Yeah, pretty standard procedure. I've usually had access to the spec to be sure the friction surface isn't worn too far down, but that info isn't result available in the states heh.

Can you not just measure it of the outer edge that’s not worn/damaged and use that as your datum point. Get the post height etc.

Yeah, I actually finally took a good look at it, there is pretty much no groove where the disk was, so what ever they take off the friction surface then can machine off the mounting surface
