7.
Install the crankshaft bearing caps in the original position and
with the arrow on the crankshaft bearing caps in the direction of
the front of the engine block.
8.
Install the crankshaft bearing cap bolts and the crankshaft bear-
ing cap studs.
9.
Thrust the crankshaft rearward in order to set and align the
crankshaft thrust bearings and the crankshaft bearing caps.
10.
Thrust the crankshaft forward in order to align the rear faces of
the crankshaft thrust bearings.
11.
Look to ensure that the crankshaft bearing caps are fully seated
in the engine block crankshaft bearing cap channel and that the
crankshaft bearing caps are centered on the engine block bulk-
heads.
12.
Tighten the crankshaft bearing cap bolts.
a.
Tighten the crankshaft bearing cap bolts on the first pass to
20 N•m (15 lb. ft.).
b.
Tighten the crankshaft bearing cap bolts on the final pass
an additional 73 degrees using the J 36660.
13.
Measure the crankshaft end play.
a.
Firmly thrust the crankshaft rearward, and then forward.
This will align the crankshaft rear bearing thrust surfaces.
b.
With the crankshaft pushed forward, insert a feeler gauge
between the crankshaft and the crankshaft rear bearing
thrust surface to measure the clearance. Crankshaft end
play 0.05-0.20 mm (0.002-0.008 in)
14.
Rotate the crankshaft in order to check for binding.
A bent crankshaft or lack of proper crankshaft bearing clearance
may cause binding.
15.
If the crankshaft does not turn freely, loosen the crankshaft
bearing cap bolts on 1 crankshaft bearing cap at a time in order
to determine the location of the binding.
A lack of proper crankshaft bearing clearance may be caused by
the following:
• Burrs on the crankshaft bearing cap
• Foreign material between the crankshaft bearing and the
engine block
• Foreign material between the crankshaft bearing and the
crankshaft bearing cap
• Damaged crankshaft bearing
• Improper size crankshaft bearing
