11. Install a magnetic base indicator tool,
J 7872, or equivalent, on the block with the
plunger against a crankshaft counterweight
to check crankshaft end play.
12. Using a suitable pry bar, move the
crankshaft either forward or rearward until it
stops. Tap the end of the crankshaft with a
plastic-faced hammer to seat the thrust
washer.
13. Using the pry bar, move the crankshaft in the
opposite direction. Tap the end of the
crankshaft with a plastic-faced hammer to
seat the other thrust washer.
14. Set the dial on the indicator to zero.
15. Using the pry bar, move the crankshaft in the
opposite direction and read the dial
indicator. Refer to the allowable tolerances
under Fits and Limits in the
SPECIFICATIONS section.
16. If the end play is out of specification, remove
the thrust washers and install properly sized
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
aluminum-faced bearing surface of the thrust
washer against the crankshaft when installing the
thrust washers.
17. Install the center main bearing cap, with
bearing insert and the correct thrust washer
sections in place, and torque the bearing
capscrews to specification.
18. Recheck the end play to ensure the thrust
washers have been installed correctly and
that end play is within specification. Rotate
the crankshaft to ensure there is no binding.
