a. Inspection.
NOTE
Unless flywheel housing has obvious
damage, measure it for flywheel
housing-to-crankshaft
concentricity
to determine whether it needs to be
replaced.
(1)
Attach dial indicator to crankshaft (1) as shown.
(2)
Position dial indicator at 12 o'clock position.
Adjust dial until it reads zero.
(3)
Slowly rotate crankshaft (1) until indicator
reaches the 3 o'clock, 6 o'clock, 9 o'clock, and
12 o'clock positions. Record indicator
measurements at each position.
NOTE
When the indicator reaches the 12 o'clock position again, be sure the indicator
needle points to zero. If needle does not point to zero, results will be incorrect and
it will be necessary to perform step (3) again.
(4)
With dial indicator at 12 o'clock and using a pry bar, carefully raise rear of crankshaft (1). Record the
measurement from the dial indicator. This measurement is called bearing clearance.
(5)
Determine bearing clearance adjustment by subtracting 1/2 of bearing clearance measurement, obtained in step
(5), from 6 o'clock position, recorded in step (3). See Example 1.
