ASSEMBLY
(1) Before i n s t a l l i n g pistons, a n d connecting rod as-
semblies i n t o the bore, be sure t h a t compression r i n g
gaps are staggered so t h a t n e i t h e r is i n l i n e w i t h o i l
r i n g r a i l gap.
(2) Before i n s t a l l i n g t h e r i n g compressor,
make
sure t h e o i l r i n g expander ends a r e b u t t e d a n d t h e
r a i l gaps located as shown i n (Fig. 5).
(3) Immerse the piston head a n d r i n g s i n clean en-
gine o i l , slide the r i n g compressor, Tool C-385, over
the p i s t o n and t i g h t e n w i t h t h e special w r e n c h (part
of Tool C-385). Be sure position o f r i n g s does n o t
change d u r i n g this operation.
(4) I n s t a l l connecting r o d b o l t protectors on r o d
bolts, t h e long protector should be i n s t a l l e d o n t h e
numbered side of the connecting r o d .
(5) Rotate crankshaft so t h a t t h e connecting r o d
j o u r n a l is o n the center o f the c y l i n d e r bore. Insert
rod a n d piston into cylinder bore a n d guide r o d over
the crankshaft j o u r n a l .
(6) T a p the piston d o w n i n c y l i n d e r bore, u s i n g a
h a m m e r handle. A t the same t i m e , guide connecting
rod i n t o position on crankshaft j o u r n a l .

BEARINGS
F i t a l l rods on one b a n k u n t i l completed. Do not a l -
ternate f r o m one b a n k t o another, because w h e n the
rods are assembled t o pistons correctly, they are not
interchangeable from one b a n k t o another.
The
bearing caps are n o t interchangeable a n d
should be marked a t r e m o v a l t o i n s u r e correct as-
sembly.
Each bearing cap has a s m a l l V groove across the
p a r t i n g face. When
i n s t a l l i n g t h e lower
bearing
shell, m a k e certain t h a t t h e V groove i n t h e shell is
i n l i n e w i t h the V groove i n t h e cap. This provides
l u b r i c a t i o n of the cylinder w a l l i n t h e opposite bank.
