14. REMOVE CONNECTING ROD CAPS AND CHECK OIL
CLEARANCE
(a) Check the matchmarks on the connecting rod cap and
connecting rod to ensure correct reassembly.
(b) Remove the connecting rod cap nuts.
(c) Using a plastic− faced hammer, lightly tap the connecting
rod bolts and lift off the connecting rod cap.
HINT:

(h) Install the connecting rod cap with the 2 nuts (See page EM−103 ).
NOTICE:
Do not turn the crankshaft.
(i) Remove the 2 nuts and connecting rod cap (See proce-
dure (b) and (c) above).
(j) Measure the Plastigage at its widest point. Standard oil clearance:
STD0.032 − 0.050 mm (0.0013 − 0.0020 in.)
U/S 0.250.033 − 0.073 mm (0.0013 − 0.0029 in.)
Maximum oil clearance: 0.10 mm (0.0039 in.)
If the oil clearance is greater than maximum, replace the bear-
ings. If necessary, grind or replace the crankshaft.
HINT:
If using a standard bearing, replace with one having the same
number. If the number of the bearing cannot be determined, se-
lect the correct bearing by adding together the numbers im-
printed on the connecting rod and crankshaft, then selecting
the bearing with the same number as the total. There are 5 sizes
of standard bearings, marked ”2”, ”3”, ”4”, ”5” and ”6” according-
ly.
Reference
Connecting rod big end inside diameter:
Mark ”1”60.526 − 60.532 mm (2.3829 − 2.3831 in.)
Mark ”2”60.532 − 60.538 mm (2.3831 − 2.3834 in.)
Mark ”3”60.538 − 60.544 mm (2.3834 − 2.3836 in.)
Crankshaft crank pin diameter:
Mark ”1”56.994 − 57.000 mm (2.2439 − 2.2441 in.)
Mark ”2”56.988 − 56.994 mm (2.2436 − 2.2439 in.)

rect order.
16. CHECK CRANKSHAFT THRUST CLEARANCE
Using a dial indicator, measure the thrust clearance while prying
