Crankshaft
1. Before installing the crankshaft, inspect the main bearing
oil clearances as follows.
Oil clearance inspection
(1) Remove all foreign material and oil from the journals and
bearings.
Caution
l Install the grooved upper main bearings in the cyl-
inder block.
l Install the thrust bearings with the oil groove fac-
ing the crankshaft.
(2) Install the upper main bearings and thrust bearings.
(3) Set the crankshaft in the cylinder block.
Caution
l Do not rotate the crankshaft when measurlng the
oil clearances.
(4) Position Plastigage atop the journals in the axial di-
rection.
(5) Install the lower main bearings and the main bearing
caps according to the cap number and + mark.
(6) Tighten the main bearing cap bolts in two or three steps
in the order shown in the figure.
Tightening torque:
54-59 N-m (5.5-6.0 m-kg, 40-43 ft-lb)
(7) Remove the main bearing caps, and measure the P lasti-
gage at each journal at the widest point for the smallest
clearance and at the narrowest point for the largest
clearance.
(8) If the oil clearance exceeds specification, grind the
crankshaft and use undersize main bearings.
(Refer to page Bl-64.)
Oil clearance: 0.016-0.036mm (0.0007-0.0014 in)
Maximum: O.lOmm (0.004 in)
2. Apply a liberal amount of clean engine oil to the main bear-
ings, thrust bearings and main journals.
3. Install the crankshaft and the main bearing caps accord-
ing to the cap number and + mark.

Oil clearance: 0.028-0.068mm (0.001 l-0.0027 in)
Maximum: O.lOmm (0.004 in)
2. If the oil clearance exceeds the maximum, grind the crank-
shaft and use undersize bearings. (Refer to page Bl-64.)
3. Measure the connecting rod side clearances.
Side clearance: 0.11 O-0.262mm (0.0043-0.0103 in)
Maximum: 0.30mm (0.012 in)
4. If the clearance exceeds the maximum, replace the con-
necting rod and cap.
5. Apply a liberal amount of clean engine oil to the crankpin
journals and connecting rod bearings.
6. Install the connecting rod caps with the matching marks
aligned.
7. Tighten the connecting rod cap nuts in two or three steps.
