This is an industrial 2-step two step flywheel that came in to be surfaced. The flywheel was pretty well worn so the clutch was slipping and not transferring enough power from the engine to the transmission. You can see the grooves and low spots in the picture before we surfaced the flywheel. In the other picture you can see that the surface of the flywheel is shiny, smooth, and flat. If your clutch is worn and your flywheel needs to be surfaced give us a call or bring it by. We can surface most any automotive, industrial, gas, diesel, and marine flywheels on our Winona Van Norman flywheel grinder which is a state of the art flywheel surfacing machine.
