of the piston skirt. Refer to Chart, Fig. 23, for proper
the rod bolts to strike or scrape across it. Place caps on
clearance. The thrust faces on the piston skirt are 900
rods immediately so that they will not be mismatched in

section of the piston skirt toward the maximum thrust
side, or opposite the crankshaft rotation.
