well that at least .125 thinner - makes sense.
I think like the brake drums.., these items were never designed to be resurfaced. I think you have a much better chance resurfacing the pressure plate than you have resurfacing the brake drums. I think the key word is to be ultra conservative and do as little harm as possible. There was a noticeable visible difference between my old and new plates. The area from the bottom of the arm post to the surface of a new pressure plate is only about 1/4" (0.250). The plate I refurbished was 0.191 when I started and ended up at 0.185. I would estimate .065" under original size. I would guess that this is not the first time my new plate was been refurbished.
The old pressure plate would have worked if the arms didn't come in contact with the bearing fork which caused the plate to crack across the arm post. If we can learn anything about our cars from this mishap it is; never run the engine without the transmission unless you remove the pressure plate and clutch. In my opinion.
The thickness of the metal from the bottom of the arm post to the plate surface on the old pressure plate was approximately 0.065". If you add this to the 0.125" difference it equals 0.190. Approximately where I started with my new old plate.
