INSTALLATION
(1) Install the piston rings. (Refer to 9 - ENGINE/
ENGINE BLOCK/PISTON RINGS - INSTALLA-
TION)
NOTE: The connecting rod bearing cap bolts must
be examined before reuse. If the threads are necked
down, the bolts must be replaced.
(2) Check connecting rod bolts for necking by hold-
ing a scale or straight edge against the threads. If all
threads do not contact the scale, the bolt must be
replaced (Fig. 83).
(3) Before installing pistons and connecting rod
assemblies into the bore, ensure that compression
ring gaps are staggered so that neither is in line with
oil ring rail gap (Fig. 84).
