REPAIR INSTRUCTIONS, PART 1
Page 199
Make sure that the thrust washers are installed
correctly when assembling the engine. Failure to
heed this caution may result in severe engine
damage.
11. Using a torque wrench, tighten the screws
according to specification.
12. Using a suitable pry bar, move the
crankshaft toward the front or rear of the
engine until it stops.
13. Using a plastic mallet, tap the end of the
crankshaft to seat the thrust washers.
14. Using the pry bar, move the crankshaft in the
opposite direction.
15. Using a plastic mallet, tap the opposite end
of the crankshaft to seat the thrust washers
on the other side.
Refer to allowable crankshaft end play tolerances
under Fits and Limits in the SPECIFICATIONS
section.
16. Using a magnetic base indicator tool with its
feeler against a crankshaft counterweight,
check crankshaft end play as follows.
a. Set the dial indicator to zero.
b. Using the pry bar, move the crankshaft
endwise and read the indicator.
c. If end play is out of specification,
remove the thrust washers and install
washers of suitable thickness to meet
specification.
The thickness of the thrust washers in the bearing
cap must match the thickness of the thrust
washers in the cylinder block. Be sure to put the
aluminum bearing surface against the crankshaft.
Failure to heed this caution may result in severe
component damage.
17. Using a torque wrench, with the correct
thrust washer sections in place, tighten all
bearing cap screws according to
specification.
18. Recheck the end play to be sure that the
thrust washers have been installed correctly
and that end play is within specification.
19. Rotate the crankshaft to be sure that it turns
freely.
