TRANSMISSION LUBRICANT

TRANSMISSION LUBRICATION: TOURING
MODELS

General

The transmission lubricant level should be checked monthly.

Refer to

Table 1-1

. The transmission should be drained and

refilled with fresh lubricant at specified intervals.

NOTE

When checking the transmission lubricant level, the motorcycle
should be leaning on the jiffy stand. Allow a short period of
time to equalize lubricant level in the transmission compart-
ments.

Check Lubricant Level

Park motorcycle on its jiffy stand.

See

Figure 1-13

. Remove the threaded filler plug/dipstick.

See

Figure 1-14

. Wipe off filler plug/dipstick. Place in filler

hole and remove. (Dipstick should rest on lip of filler. Do
not screw in.) Lubricant level should be between the full
and low marks on the plug/dipstick when removed.

Be sure that no lubricants or fluids get on tires, wheels or
brakes when changing fluid. Traction can be adversely
affected, which could result in loss of control of the
motorcycle and death or serious injury. (00047d)

When draining or adding lubricant, do not allow dirt, debris
or other contaminants to enter the engine. (00198a)

Add lubricant, if necessary. Do not overfill or leakage may
occur. When filling the transmission, use GENUINE Harley-
Davidson FORMULA+ TRANSMISSION AND PRIMARY
CHAINCASE LUBRICANT (Part No. 99851-05 quart). The
transmission fluid capacity is approximately 32 fluid
ounces (0.95 liters).

Inspect o-ring for tears or damage. Replace if required.
Wipe any foreign material from plug.

Install threaded filler/check plug and tighten clockwise to
25-75 in-lbs (2.8-8.5 Nm).

ADJUSTMENT

NOTE

Perform the clutch adjustment with the motorcycle at room
temperature. The clearance at the adjuster screw will increase
as the powertrain temperature increases. If adjuster screw is
adjusted with powertrain hot, clearance at push rod bearing
could be insufficient with powertrain cold and clutch slippage
could occur.

Stand motorcycle upright and level.

Remove five screws to free clutch inspection cover from
primary chaincase cover.

Remove seal ring from clutch inspection cover and discard.

See

Figure 1-15

. Add freeplay to cable.

from cable adjuster.

Move adjuster toward jam nut to introduce a large
amount of free play at hand lever.

See

Figure 1-16

. Loosen jam nut on clutch adjuster screw.

To take up all free play, turn screw inward (clockwise) until
lightly seated.

Back out adjuster screw 1/2 to 1 full turn. While holding
adjuster screw with an allen wrench, tighten jam nut to 72-
120 in-lbs (8.1-13.6 Nm), while holding adjusting screw
with an Allen wrench.

Squeeze clutch lever to maximum limit three times to set
ball and ramp release mechanism.

Check freeplay.

Turn cable adjuster away from jam nut until slack is
eliminated at hand lever.

to 40°.

6-20 2008 Touring Service: Drive

10. Install lockplate over transmission sprocket nut so that two

of lockplate's four drilled holes (diagonally opposite) align
with sprocket's two tapped holes. To find the best fit,
lockplate can be rotated to a number of positions and can
be placed with either side facing sprocket.

NOTE

Maximum allowable tightening of sprocket nut is 45° of clock-
wise rotation after a torque of 35 ft-lbs (47.5 Nm). Do not loosen
sprocket nut to align holes or nut will be under tightened.

11. If holes in lockplate do not align with those in sprocket,

continue to tighten sprocket nut (up to the 45° maximum)
until sprocket and lockplate holes are in alignment.

NOTES

•

New screws have LOCTITE patches. With LOCTITE High
Strength Threadlocker 271 (red) reapplied before installa-
tion, the screws can be re-used up to three times.

•

To ensure the lockplate's security, BOTH screws must be
installed in the lockplate.

REAR BELT AND SPROCKETS

GENERAL

When a drive belt is replaced for any reason other than stone
damage, it is recommended that the transmission and rear
sprockets also be replaced to increase the longevity of the new
drive belt. In the case of stone damage, inspect sprockets for
damage and replace as required.

Never bend belt forward into a loop smaller than the drive
sprocket diameter. Never bend belt into a reverse loop.
Over bending can damage belt resulting in premature
failure, which could cause loss of control and death or
serious injury. (00339a)

CLEANING

Keep dirt, grease, oil, and debris off the belt and sprockets.
Clean the belt with a rag slightly dampened with a light cleaning
agent.

INSPECTION

Sprockets

NOTE

If chrome chips or gouges to rear sprocket are large enough
to be harmful, they will leave a pattern on the belt face.

See

Figure 1-18

. Inspect each tooth (1) of rear sprocket

for:

Major tooth damage.

Large chrome chips with sharp edges.

Gouges caused by hard objects.

Excessive loss of chrome plating (see next step).

To check if chrome plating has worn off, drag a scribe or
sharp knife point across the bottom of a groove (2)
(between two teeth) with medium pressure.

If scribe or knife point slides across groove without
digging in or leaving a visible mark, chrome plating
is still good.

If scribe or knife points digs in and leaves a visible
mark, it is cutting the bare aluminum. A knife point
will not penetrate the chrome plating.

Replace rear sprocket if major tooth damage or loss of
chrome exists.

Groove

Figure 1-18. Rear Sprocket

Rear Belt

See

Figure 1-19

. Inspect drive belt for:

•

Cuts or unusual wear patterns.

•

Outside edge bevelling (8). Some bevelling is common,
but it indicates that sprockets are misaligned.

•

Outside ribbed surface for signs of stone puncture (7). If
cracks/damage exists near edge of belt, replace belt
immediately. Damage to center of belt will require belt
replacement eventually, but when cracks extend to edge
of belt, belt failure is imminent.

•

Inside (toothed portion) of belt for exposed tensile cords
(normally covered by nylon layer and polyethylene layer).
This condition will result in belt failure and indicates worn
transmission sprocket teeth. Replace belt and transmission
sprocket.

•

Signs of puncture or cracking at the base of the belt teeth.
Replace belt if either condition exists.

•

Replace belt if conditions 2, 3, 6 or 7 (on edge of belt)
exist.

NOTE

Condition 1 may develop into 2 or 3 over time. Condition 1 is
not grounds for replacing the belt, but it should be watched
closely before condition 2 develops which will require belt
replacement.

CHECKING BELT DEFLECTION

TOOL NAME

PART NUMBER

BELT TENSION GAUGE

HD-35381A

Check rear belt deflection:

•

As part of pre-ride inspection.

•

At every scheduled service interval.

Check belt deflection:

•

With transmission in neutral.

•

At loosest spot in belt.

•

With motorcycle at ambient temperature.

•

With motorcycle upright and rear wheel in air or on jiffy
stand without rider or luggage.

Remove left side saddlebag.

See

Figure 1-20

. Obtain BELT TENSION GAUGE (Part

No. HD-35381A).

NOTE

Customers may purchase gauge from an authorized Harley-
Davidson dealer.

To use the belt tension gauge:

Slide O-ring toward 0 lbs (0 kg) mark.

Fit cradle against bottom of belt half way between
transmission and rear wheel compensator sprockets.
See

Figure 1-21

While observing belt deflection through the window
on the debris deflector, push upward on knob until O-
ring slides down to the 10 lbs (4.5 kg) mark.

NOTE

Next to the deflection window is a graduated scale. Each
graduation represents 1/8 in. (3.2 mm) of belt deflection.

Rotate rear wheel and measure deflection at different
spots on the belt. Compare results with specifications in

Table 1-10

If deflection is within specification, install left side
saddlebag.

If deflection is not within specification, see

1.13 REAR

BELT DEFLECTION, Setting Belt Deflection

NOTE

Always use BELT TENSION GAUGE (Part No. HD-35381A)
to measure belt deflection. Do not rely on "feel" as this can
result in belts that are under tensioned. Loose belts will fail due
to "ratcheting" (jumping a tooth) with resultant tensile cord
crimping and breakage.

AXLE NUT TORQUE ADAPTER

HD-47925

Initial Set-up

Remove right side saddlebag.

Remove E-clip from groove at end of axle.

NOTE

The Axle Nut Torque Adapter simplifies the belt adjustment
procedure by allowing the cone nut to be loosened and
tightened without having to remove the right side muffler. The
tool also can be used to rotate the weld nut on the left side.

Loosen cone nut as follows:

Obtain breaker bar with 1/2 inch drive head and AXLE
NUT TORQUE ADAPTER (Part No. HD-47925).

Install torque adapter perpendicular to breaker bar.

Insert tool up between rear wheel and muffler to
capture cone nut. For best clearance with muffler, be
sure torque adapter is on the outboard side.

Rotate cone nut in a counter-clockwise direction until
loose.

Obtain torque wrench with 1/2 inch drive head and AXLE
NUT TORQUE ADAPTER (Part No. HD-47925). Proceed
as follows:

Install torque adapter perpendicular to torque wrench.
See upper frame of

Figure 1-22

Insert tool up between rear wheel and muffler to
capture cone nut. For best clearance with muffler, be
sure torque adapter is on the outboard side. See lower
frame of

Figure 1-22

NOTE

Since any extension can act as a torque multiplier, the
torque wrench must be perpendicular to the torque adapter
when the cone nut is tightened. The 90° orientation
between the tools cancels the multiplier effect and prevents
the cone nut from being over-tightened. If the torque
adapter is kept in-line with the torque wrench, the multiplier
effect is in force and parts damage will occur.

Verify that cam just contacts weld nub on both sides
of rear swingarm. If necessary, push wheel forward
slightly to achieve the desired result. See

Figure 1-23

Snug the cone nut to 15-20 ft-lbs (20-27 Nm).

Use BELT TENSION GAUGE (Part No. HD-35381A) to
check belt deflection. See

1.13 REAR BELT DEFLEC-

TION, Checking Belt Deflection

If belt is too loose, see Belt Too Loose.

If belt is too tight, see Belt Too Tight.

If belt deflection is within specification, see Reas-
sembly.
