NOTES

•

Verify that the bearing is flush or slightly below the surface
of the crankcase. Never "pull" the bearing into position
using the retaining screws.

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)

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-34902-B). Also obtain
a suitable hardened washer to use between the puller
screw and the end of the shaft.

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.

Sparingly apply graphite lubricant to threads of forcing
screw to prolong service life and verify 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.

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.

Do not use heating devices with penetrating oil. Penet-
rating oil is flammable which could result in death or ser-
ious injury. (00375a)

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 assist removal without heat, apply a light penetrating oil to
shaft and leading edge of bearing inner race.

10. Turn forcing screw until thrust washer and bearing inner

race move approximately 1/8 in. (3.2 mm).

ensure positive contact with bearing inner race. Installing
tool with more contact than necessary will result in damage
to the flywheel (00500b)

FLYWHEEL AND CONNECTING RODS

GENERAL

Symptoms

Flywheels that shift out of true at the crank pin generally exhibit
one of two symptoms: no oil pressure or vibration. This condi-
tion is also known as scissored flywheels.

No Oil Pressure

When the right side crankshaft shifts more than 0.015 in (0.381
mm), it can break the oil pump gerotors, resulting in a loss of
oil pressure.

If a very low or no oil pressure condition is confirmed, inspect
the oil pump and cam support plate. If the oil pump gerotors
are bound or damaged, the cause is likely from a contaminant
running through the pump or a shifted crankshaft. If this type
of damage is found, always replace the oil lines and clean all
debris

from

the

oil

pan

oil

tank.

See

1.24 TROUBLESHOOTING

for general diagnostics of low oil

pressure.

Vibration

Generally, left crankshaft runout must exceed 0.020 in. (0.508
mm) to be noticeable to the rider. It is much more likely that
vibration issues will be resolved by following the checklist in

1.24 TROUBLESHOOTING

If correct chassis set-up has been verified and other items in

1.24 TROUBLESHOOTING

have been eliminated, checking

left crankshaft runout is appropriate.

INSPECTION

NOTE

Do not attempt to straighten connecting rods. Straightening
rods will damage both the upper bushing and lower bearing.

Replace the flywheel/connecting rod assembly if any of
the following conditions are noted:

Connecting rods are bent or twisted.

Connecting rods do not fall under their own weight or
are in a bind.

Sprocket teeth are worn in an irregular pattern or
chipped.

The crankshaft (roller) bearing inner races are
brinelled, burnt, scored, blued or damaged.

The crankshaft runout exceeds specification.

NOTE

Bluing on connecting rods is part of the hardening process and
is considered a normal condition.

Check connecting rod bearing clearance. Orient the
assembly as shown in

Figure 3-147

Holding the shank of each rod just above the bearing
bore, pull up and down on the connecting rods.

Any discernible up and down movement indicates
excessive lower bearing clearance. Replace the fly-
wheel/connecting rod assembly.

Measure crankshaft runout if the crankshaft is suspected
of being out-of-true.

NOTE

If the flywheel, connecting rods or right side bearing inner race
need to be replaced, then replace the entire flywheel assembly.

and secure with two screws (2). Position cross plate so
that large bolt hole in cross plate is lined up with center of
main drive gear (4).

nut until main drive gear is free.

NOTES

•

When removing the main drive gear, the gear is pressed
out against the resistance of the bearing inner race.
Without any support at the inner race, the bearing is des-
troyed. Whenever the main drive gear is removed the main
drive gear bearing must also be replaced.

•

Compressed air can pierce the skin and flying debris from
compressed air could cause serious eye injury. Wear
safety glasses when working with compressed air. Never
use your hand to check for air leaks or to determine air
flow rates. (00061a)

Clean all parts in solvent except the transmission case
and needle bearings. Dry with compressed air.

NOTE

Never wash the transmission case and needle bearings with
solvent unless replacing the needle bearings. Normal cleaning
methods will wash dirt or other contaminants into the bearing
case (behind the needles) and will lead to bearing failure.

Inspect the main drive gear for pitting and wear. Replace
if necessary.

Inspect the needle bearings inside the main drive gear.
Replace the needle bearings if the mainshaft race is pitted
or grooved.

HOME

6-24 2013 Softail Service: Transmission

Replace the sprocket if teeth are cracked or worn. See

5.7 TRANSMISSION SPROCKET, Cleaning and Inspec-
tion

for more information.

Inspect the needle bearings on the inside of the main drive
gear. If mainshaft race surface appears pitted or grooved,
replace these bearings.

NOTE

If replacing the main drive gear needle bearings and/or seal,
continue as follows. Otherwise, proceed to

Needle Bearing Replacement

Wear safety glasses or goggles when removing or
installing retaining rings. Retaining rings can slip from the
pliers and could be propelled with enough force to cause
serious eye injury. (00312a)

NOTES

•

See

Figure 6-38

. When replacing needle bearings, discard

original retaining rings (1) and install replacement retaining
rings (2).

•

To install the inner main drive gear needle bearings and
mainshaft seal, use MAIN DRIVE GEAR BEARING AND
SEAL INSTALLATION TOOL (Part No. HD-47932).

See

Figure 6-37

. Remove mainshaft seal (6). Remove

retaining rings (1), needle bearings (2) and spacer (5) from
main drive gear (3). Discard retaining rings.

NOTE

CROSS PLATE (Part No. HD-35316-3A) will retrofit to earlier
transmissions. Note that one end of cross plate is stamped,
"UP 6 SPEED". Mount cross plate with this end pointing up for
6 speed transmissions.

See

35316-3A) (2) on right side of transmission case as shown,
and secure with two screws (3). Position cross plate with
large bolt hole in cross plate aligned with main drive gear
bearing bore.

Apply a light coat of graphite lubricant to the threads of 12
IN. BOLT (Part No. HD-35316-5) (1) and install through
cross plate and main drive gear bearing bore.

At left side of case, place main drive gear bearing (4),
BEARING DRIVER (Part No. HD-35316-8) (5), BEARING
