I laugh at people who think you gotta resurface a flywheel to do a clutch job
did it not work before or something? lol
like all the sudden your flywheel is going to stop working properly or your clutch is going to chatter or slip when you put a new clutch disc in.... its going to be just like before!
the most I do is sand them with a DA to get the old material off......
now if you have a problem directly related to the flywheel...... then go ahead and fix it! If not leave it alone and put that money elsewhere...... like a bank, or a night out, or other SHO parts that will have a bigger effect
we've done THOUSANDS of clutch jobs without resurfacing flywheels..... decades of jobs....
have you ever done a brake job without resurfacing the rotors or replacing them? if you didn't have any issues before, the addition of new pads is not going to create one. As long as the rotor meets certain specs/tolerances it is ok to reuse, with cleaning it the most work you do to it, this is per OEM instructions....
