Piston stroke: 0.42 to 0.72 mm (0.0165 to 0.0283 in.)

If the piston stroke is outside the specification, parts may have been assembled incorrectly. Perform the reassembly again.

If the piston stroke is still outside the specification, select another flange. HINT:

There are 4 different thicknesses for the flange.
