1.6 Installing the piston rings
Using the special tool Piston Ring Pliers, install
the No. 1 ring, No. 2 ring, and oil ring onto the
piston.
Special tool
Part number
Piston Ring Pliers
31391-12900
Note: (a) Install the rings so that “T” mark faces the
top of the piston.
(b) The oil ring should be installed so that the
butt joint of the coil spring is located at 180
o
relative to the ring gap as illustrated.
1.7 Installing the piston/connecting rod
assemblies
(1)
Apply engine oil onto the periphery of the piston
and the piston rings.
(2)
Position the piston ring gaps as illustrated. The
gaps should not face the same direction as the
piston pin or squarely with the piston pin
(3)
Install the connecting rod bearing (upper) onto
the connecting rod, ensuring that the lug
engages with the lug groove.
(4)
Rotate the crankshaft until the crank pin onto
which the piston/connecting rod assembly is
being installed comes to the top dead center.
(5)
Face the piston/connecting rod assembly so that
the arrow mark on top of the piston points to the
timing gear case side (front) of the engine.
(6)
Using a piston guide (available on the market),
insert the piston/connecting rod assembly from
the top of the cylinder block down.
Do not tap the piston too hard. Doing so may
break the piston rings or damage the crank
pin.
