Rejection sizes of crankpin bearing hole and piston pin bearing hole are

shown in Table No. 7. Piston. pins .005" oversize are available in case

the connecting rod and piston are worn at the piston pin bearing. If, how-

5.2.2.7.7

Assemble Piston and Connecting Rod.

This piston pin is a push fit in both piston and connecting rod. On models

using a solid piston pin, one end is flat, the other end is recessed. Other

models use a hollow pin.

Place a pin lock in the groove at one side of the piston. From the opposite

side of the piston, insert the piston pin, flat end first with solid pin, either

end with hollow pins, until it stops against the pin lock. Use a thin nose

pliers to assemble the pin lock in the recessed end of the piston. Be sure

the locks are firmly set in the grooves.
