b. Crosshead guide to crosshead clearance at the top (at side, top and bottom ends for JGI) is to be
checked by inserting a standard 0.500 inch (13 mm) wide feeler stock from one side edge of the cross-
head across to the opposite side. This is to be done at both ends. The bottom clearance is to be
checked with 0.0015 inch (0.038 mm) feeler stock at the 4 corners. If the feeler can be inserted more
than 0.500 inches (13 mm), the assembly is not acceptable.
