Service manual

11. 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 bulkheads.
12. Measure the crankshaft end play.
12.1. Tighten the crankshaft bearing cap bolts
and the crankshaft bearing cap studs
finger tight.
12.2. Firmly thrust the crankshaft rearward, and
then forward.
This will align the crankshaft rear bearing
thrust surfaces.
12.3. With the crankshaft pushed forward, insert
a feeler gauge between the crankshaft
and the crankshaft rear bearing thrust
surface to measure the clearance.
Specification
Crankshaft end play 0.05–0.20 mm (0.002–
0.008 in)
Notice: Refer to Fastener Notice in Cautions and
Notices.
13. Tighten the crankshaft bearing cap bolts and the
crankshaft bearing cap studs.
Tighten
13.1. Tighten the crankshaft bearing cap bolts
and the crankshaft bearing cap studs on
the first pass to 20 N·m (15 lb ft).
13.2. Tighten the crankshaft bearing cap bolts
and the crankshaft bearing cap studs
(2 bolt caps) on the final pass to
73 degrees using the
J 36660-A .
13.3. Tighten the bearing cap outboard bolts
(4 bolt caps) on the final pass to
43 degrees using the
J 36660-A .
13.4. Tighten the bearing cap inboard bolts and
the bearing cap inboard studs (4 bolt
caps) on the final pass to 73 degrees using
the
J 36660-A .
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
