with the grooves facing outward.

(b)

Install the main bearing caps in numerical order with the
arrows facing forward.

8.

INSTALL MAIN BEARING CAP BOLTS

HINT:

The main bearing cap bolts are tightened in 2 progressive
steps (steps (b) and (d)).

If any of the main bearing bolts break or deform, replace
them.

(a)

Apply a light coat of engine oil on the threads and under
the heads of the main bearing cap bolts.

(b)

Install and uniformly tighten the 14 main bearing cap
bolts, in several passes, in the sequence shown.
Torque: 45 N·m (450 kgf·cm, 33 ft·lbf)

If any one of the main bearing cap bolts does not meet the
torque specification, replace the main bearing cap bolt.

(c)

Mark the front of the main bearing cap bolt head with
paint.

(d)

Retighten the main bearing cap bolts 90

°

in the numerical

order shown above.

(e)

Check that the painted mark is now at a 90

°

angle to the

front.

(f)

Check that the crankshaft turns smoothly.

9.

CHECK CRANKSHAFT THRUST CLEARANCE

Using a dial indicator, measure the thrust clearance while prying
the crankshaft back and forth with a screwdriver.

Standard thrust clearance:
0.020 – 0.220 mm (0.0008 – 0.0087 in.)
Maximum thrust clearance:
0.30 mm (0.0118 in.)

If the thrust clearance is greater than maximum, replace the
thrust washers as a set.
