PISTON ASSEMBLY INSTALLATION - CONTINUED
Over expanding piston rings during installation on piston can cause piston ring dis-
tortion. This will cause scoring of cylinder sleeves and premature piston ring failure.
Never file or grind chrome plated piston rings.
Never use chrome plated piston rings in chrome plated cylinder sleeves.
Expand piston rings only enough to pass over piston.
Piston rings must be installed in same number piston and cylinder sleeve that ring end
gap was checked.
2. Piston assembly (1)
compression ring (2),
new compression ring
(3), new compression
ring (4), and new
oil ring (5)
Using ST-763 piston ring expander,
expand each ring and install in proper
ring groove on piston as shown.
Rotate piston rings to separate ring end-
gap openings as shown.
3. Connecting rod (6)
Two nuts (7), two
new hardened con-
necting rod washers
(8), and connecting
rod cap (9)
Unscrew and take off.
rod bolts (10)
Using suitable covering, cover threads.
Before performing next step, coat piston sides, piston rings, and upper connecting rod
bearings with lubricating oil and position piston ring end gap 90 degrees apart.
5. Piston (1)
pression ring (2),
compression ring (3),
compression ring (4),
and oil ring (5)
Using ST-1176 piston ring compressor,
compress piston rings to piston.
