The key callouts are a 3.00 inch bore with a bore tolerance of ±0.002 inch, a 2.44 inch groove diameter, and a 0.269 inch seal height. The seal cross section is 0.087 inch. It also lists a piston diameter of 2.999 inch with a +0/-0.006 tolerance, and that piston diameter is specified for pistons without wear rings.
