Forked or female rod –
assemble to rear cylinder
rim of top wheel until wheels are concentric. Tighten nut,
recheck with straightedge at frequent intervals.
NOTE
Use soft metal hammer to realign wheels.
9. Tighten crank pin nut to 150-185 ft-lbs (203-251 Nm).
See Figure 3-85. Install flywheel assembly in
TRUING STAND (Part No. HD-96650-80)
Adjust so centers are snug. Wheels must turn freely;
however, shafts must not be loose in centers. If flywheel
assembly is either loose or squeezed, indicators will not
indicate accurately. Adjust indicators to take reading as
near to flywheels as possible, so pointers read at about
the middle of the scales.
10. Turn flywheels slowly and observe the movement of indi-
cator pointers. Movement toward flywheels indicate high
points of shafts. Find highest point of each shaft and
chalk-mark flywheel rims at those points. Remove fly-
wheel from stand and make corrections as follows:
11. See Figure 3-84. Flywheel may be out of true three ways,
A, B and C or a combination of two of the three ways.
12. When wheels are both out of true as indicated in A,
tighten C-clamp on rims or wheels opposite crank pin
and lightly tap the rim at the crank pin with lead or copper
mallet.
13. When wheels are both out of true as indicated in B, drive
a hardwood wedge between the wheels opposite the
crank pin and lightly tap the rims near the crank pin with
a lead or copper mallet.
14. When wheels are out of true as indicated in C, strike the
rim of the wheel a firm blow at about 90° from crank pin
on high side.

as shown.
15. When wheels are out of true in a combination of any of
the conditions shown, correct C first, tapping rim of
offending wheel only, and then correct condition A or B.
The number of blows required and how hard they should be
struck depends on how far shafts are out of true and how tight
nuts are drawn. Always remove the flywheels from the stand,
and strike the flywheel rim only at 90 ° to the crank pin. Use
only a soft metal mallet. Never strike wheels a hard blow near
crank pin. This could result in a broken crank pin .
16. See
take reading from indicator. Repeat truing operation until
indicated shaft runout does not exceed 0.001 in.
(0.025 mm) (each graduation on indicator is 0.002 in.
(0.05 mm)).
