bearing shells in connecting rod caps. The
locating tang on the shell must index with
milled recess in cap. Numbers on rod and
cap must match (1 to 1, 2 to 2, etc.) and
must be toward outside of their respective
banks and must indicate proper position in
cylinder block: IL for left bank, IR for right
bank, etc. Stamp if new rod is being used.
This provides proper clearance between rod
crankpin end chamber and crankshaft rod
journal fillet.
(15) Completely lubricate bolt threads with
engine lubricating oil. Lubricate hardened
washers and bolt head mating surface with
SAE 140-W lubricant.
(16) Assemble caps and bearing shells over rod
bolts and install washers and nuts.
(a) Tighten
connecting
rod
bolt
nuts
alternately to 70 to 80 foot-pounds (95
to 108 joules).
(b) Tighten the nuts on each connecting rod
alternately to 140 to 150 foot pounds
(190 to 203 joules).
(c) Completely loosen both nuts on each
connecting rod to relieve all tension.
(d) Tighten the nuts on each connecting rod
alternately to 70 to 80 foot-pounds (95
to 108 joules).
(e) Tighten the nuts on each connecting rod
alternately to 140 to 150 foot-pounds
(190 to 203 joules).
(f) The breakaway torque in tightening
direction should be 140 to 180 foot-
pounds (190 to 244 joules).
(17)
Check for clearance of 0.008 to 0.022 inch (0.20
to 0.56 mm) between rod assemblies located on same
journal. Rods should move freely sideways with hand
pressure. Also check position of rod on piston pin and
make sure there is visible clearance between rod and
piston boss. This is extremely important to prevent
scoring or seizing of piston and liner.
(18)
Turn crankshaft as each piston and rod
assembly is added to gauge additional drag. Increase
will be perceptible but must not be excessive for any
one rod assembly.
