Figure 6-21 — Crankshaft Thrust Washer Installation
9. Position the lower section thrust washers on
the center bearing cap (bronze/aluminum
faces crankshaft) and install the cap. Torque
capscrews to 210 lb-ft (285 N폷m) using
torque wrench J 24407 or equivalent.
10. Install magnetic base indicator tool J 7872,
or equivalent, on the block with the plunger
against a crankshaft counterweight to check
for crankshaft end play.
11. Using a suitable pry bar, move crankshaft
either forward or rearward until it stops. Tap
end of the crankshaft with a plastic-faced
hammer to seat the thrust washer.
12. Using pry bar, move crankshaft in the
opposite direction. Tap end of the crankshaft
with a plastic-faced hammer to seat the
other thrust washer.
13. Set dial on the indicator to zero.
14. Using pry bar, move crankshaft in the
opposite direction and read the dial
indicator. Refer to the Fits and Limits chart
for specifications.
15. If end play is out of specification, remove
thrust washers and install standard or
oversize thrust washers, as required, to
bring the end play into specification.
The thickness of the thrust washers used in the
bearing cap must match the thickness of the
thrust washers in the block. Be sure to put the
bearing surface of the thrust washer against the
crankshaft when installing thrust washers.
16. Install the center main bearing cap, with
bearing insert and the correct thrust washer
sections in place, and torque the bearing
capscrews to specification.
17. Recheck end play to make sure thrust
washers have been installed correctly and
end play is within specification. Rotate
crankshaft to make sure there is no binding.
CHECKING RUNNING CLEARANCE
When using the Plastigage method of checking
running clearance, do not turn the crankshaft.
Doing so will destroy the Plastigage.
If checking the main bearing clearance with
engine in the upright position (such as in the
chassis), the weight of the crankshaft must be
removed from the lower half of the bearing being
checked. To do this, place cardboard under the
crankshaft journal in the main caps adjacent to
journal to be checked and tighten the adjacent
caps until the journal to be checked seats against
the upper bearing. Do not fully torque screws.
Capscrews on bearing being checked should be
torqued to specification after Plastigage strip has
been positioned on the bearing shell. Support
crankshaft at No. 1, 4 and 7 main journals, while
checking No. 2, 3, 5 and 6 bearings. Support
crankshaft at No. 3 and 5 while checking No. 1, 4
and 7 bearings.
