Figure 326 — Main Bearing Cap/Thrust Washer Installation
11. Install a magnetic base indicator tool,
J 7872, or equivalent, on the block and
position 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 (surface with oil
reservoir grooves and tip-face reliefs) 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.
