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.
Refer to POWERHEAD INSPECTION on p. 226.
IMPORTANT: Be sure gap of ring fits squarely
around dowel pin.
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
bearings could be misaligned. Refer to CYLIN-
DER BLOCK CLEANING on p. 225.
Coat pistons, rings, cylinder walls, and ring com-
pressor with outboard lubricant.
Center connecting rod in piston and locate piston
rings on dowel pins. Place appropriate ring com-
pressor on piston.
Slide piston and rod assembly into the correct cyl-
inder, as marked during disassembly. Guide con-
necting rod through cylinder block to avoid
scratching cylinder wall.
Cylinder Head Installation
Lightly coat both sides of a new cylinder head
gasket with Gasket Sealing Compound. Place
gasket on cylinder block following instructions
printed on gasket.
Apply soapy water to water dam and insert into
block.
