Determine rod bearing clearance for each rod as
follows:
(a)
Install four rod caps (4) on connecting
rods (3) with 12 screws (5). Tighten
screws 73 lb-ft (99 Nm).
(b)
Measure each connecting rod (3) at
position F. Record smallest diameter.
(c)
Measure crankshaft (6) at position G for
each rod (3). Normal measurement is
2.7150 to 2.7170 in. (68.961 69.012 mm).
(d)
Subtract
smallest
crankshaft
measurement from smallest connecting
rod measurement. Clearance should be
no greater than 0.0035 in. (0.0889 mm).
(e)
If rod bearing clearance exceeds 0.0035
in. (0.0889 mm), replace bearings. If
clearance still exceeds measurement limit,
replace connecting rod and rod cap.
NOTE
To ensure proper measurement of
rings, install rings with printed side
up.
(12)
Install each ring in cylinder approximately 3.5 in.
(88.9 mm) deep (position H). Level ring using
piston (1).
(13)
Remove piston (1) and measure each ring gap
at position I. If below or above limits, replace
ring. Normal measurements are as follows:
(a)
Top ring is 0.0160 to 0.0275 in. (0.4064
0.6985 mm).
(b)
Intermediate ring is 0.0100 to 0.0215 in.
(0.254 0.5461 mm).
(c)
Oil control ring is 0.0100 to 0.0215 in.
(0.254 0.5461 mm).
