Place each friction plate or steel plate on a surface plate and measure the gap between the surface plate [A] and each friction plate or steel plate [B] with a thickness gauge [С]. The gap is the amount of friction or steel plate warp.
★ If any plate is warped over the service limit, replace it with a new one.
Friction and Steel Plate Warp
Standard: 0.2 mm or less
