If your vehicle has a standard manual transmission then you most likely also have a flywheel. The flywheel can wear out & get grooves in it much like brake rotors & drums do if you let the lining on the clutch disc wear down to the metal. We perform all types of surfacing & milling here at our fully equipped Las Vegas Machine Shop. We surfaced this flywheel flat & smooth on our Winona Van Norman flywheel surface grinder.
