Removal
If reusing flywheel, remove bearing inner race and thrust
washer as follows:
1. Obtain FLYWHEEL SUPPORT FIXTURE (Part No. HD-
44358). See Figure 3-138. Install brass jaws or shop
towels around teeth of vise to prevent damage to tool.
Clamp tool in vise with the round hole topside.
2. Insert crankshaft end through hole resting flywheel
assembly on fixture. Slide knurled locating pin down slot
in tool to engage crank pin hole. Hand tighten locating pin.
3. Slide hold-down clamp down slot to engage inboard side
of right flywheel half, and then hand tighten knurled nut at
bottom to secure. Repeat step to secure hold-down clamp
on opposite side of flywheel.
NOTE
For proper clamping force, hold-down clamp must not be tilted.
Rotate hex on outboard stud until clamp is level.

4. Position WEDGE ATTACHMENT (Part No. HD-95637-
46B) on inboard side of thrust washer and turn hex nuts
an equal number of turns to draw halves of wedge
together.
Install wedge attachment only so far as necessary to
ensure positive contact with bearing inner race. Installing
tool with more contact than necessary will result in damage
to the flywheel (00500b)
5. Obtain two 3/8-16 inch bolts 7-1/2 inches long (with flat
washers). Install flat washers on bolts. Obtain bridge and
forcing screw from MAINSHAFT BEARING INNER RACE
PULLER/INSTALLER (Part No. HD-34902B). Also obtain
a suitable hardened washer or the SPORTSTER 4-SPEED
CLUTCH SPRING COMPRESSOR SCREW SEAT (Part
No. HD-95964-52).
6. Slide one bolt into channel on each side of bridge so that
flat washer is between bridge and bolt head.Thread bolts
into wedge attachment an equal number of turns.
7. Sparingly apply graphite lubricant to threads of forcing
screw to prolong service life and ensure smooth operation.
Start forcing screw into center hole of bridge.
NOTE
Failure to use hardened washer may result in damage to forcing
screw and/or sprocket shaft.
8. Place hardened washer against end of sprocket shaft.
Thread forcing screw into bridge until the steel ball at the
end of the screw makes firm contact with hardened
washer.
9. Using the ROBINAIR HEAT GUN (Part No. HD-25070),
uniformly heat the bearing inner race for about 30 seconds
using a circular motion.
NOTE
To facilitate removal without heat, apply a light penetrating oil
to shaft and leading edge of bearing inner race.
Do not use heating devices with penetrating oil. Penet-
rating oil is flammable which could result in death or ser-
ious injury. (00375a)
10. Turn forcing screw until thrust washer and bearing inner
race move approximately 1/8 in. (3.2 mm).
11. Turn hex nuts an equal number of turns to separate halves
of WEDGE ATTACHMENT (Part No. HD-95637-46B).
12. After bottoming thrust washer on shaft, reposition WEDGE
ATTACHMENT (Part No. HD-95637-46B) on inboard side
of bearing inner race. Turn hex nuts an equal number of
turns to draw halves of wedge together.
Install wedge attachment only so far as necessary to
ensure positive contact with bearing inner race. Installing
tool with more contact than necessary will result in damage
to the flywheel (00500b)
13. See Figure 3-139.Verify that the tool assembly is square,
so that the bearing inner race is not cocked during
removal.
