I know that it is standard to resurface a flywheel when doing a clutch job. I have never heard of resurfacing a pressure plate though. Is there ever a reason to resurface them? Does it have to do with them being spring loaded?

replace them.
if they are to be returned to service, the surface should be scuffed to allow the clutch disk to wear in - much like a brake disk. |

i have always replaced pressure plate and friction discs as a unit. The "fingers" on the pressure plate wear at the point that the throw out bearing presses., and considering the labor to replace a bad clucth, never thought it was economical to only replace the t=friction disc, unless you have a new clutch, that mneeds replacing for say a main seal leak that oil soaked the friction material on a low miles unit.
I always scuff up the flywheel, and new pressure plate a bit, as other poster mentioned. Be sure before install to remove any preservative coating or greases with a thinner wipe down. |

I have 3 in stock. |

Thanks for your responses. My clutch disk and pressure plate are currently in real good shape. PO had replaced them just before I bought the car. My question was just from looking at the pressure plate and wondering about it for the future.

if it's good, re-use them, but don't take any more life out of it by machining away the seating surface. i've reused pressure plates that did not have a lot of time on them.
(i don't believe in turning / grinding brake rotors either. minor grooves are not a problem, and major grooves are cause for replacement...) |

I broke the glaze with a drill and a weird grinding wheel. It was like a black spungy 1/2" thick pad. I did flywheel and pressure plate. It made a nice pattern broke the glaze and no chatter when back together. Old disk soaked in tranny oil and slipping.
