Install wrist pin through piston and connecting rod,
pushing bearing tool out through the piston.
Use Wrist Pin Cone, P/N 318600, and Driver,
P/N 318599, to install new wrist pin retaining rings
in each wrist pin hole. Gap of retaining ring faces
up, away from notch in piston.
Repeat steps for each piston.
Installing Pistons
When all pistons and connecting rods are assem-
bled, install piston ring sets. Be sure rings are
installed in the cylinder used to test ring end gap.
IMPORTANT: Be sure gap of ring fits squarely
around dowel pin.
IMPORTANT: Before continuing, make sure
that all Gel-Seal II has been removed from the cyl-
inder block and crankcase mating flanges. If
traces of hardened Gel-Seal II are left, main bear-
ings could be misaligned. Refer to CLEANING on
p. 247.
Coat pistons, rings, cylinder walls, and Ring Com-
pressor, P/N 336314 (P/N 336313 for oversize
pistons), with outboard lubricant.
Center connecting rod in piston and locate piston
rings on dowel pins. Place appropriate ring com-
pressor on piston.
