imperative that the matched combination of shoe to
ball and spherical cavity in the piston be kept intact
during disassembly after gauging operation and final

9402) with individual compartments for each compo-
nent of the mechanism will keep parts in their proper
relationship.
e. Mark piston number ( l , 2 or 3) on shoe package.

corresponding to piston number and rear bail pocket
position.
