NOTE
Only install sprocket nut while transmission is installed in frame.
Failure to do so will result in damage to transmission and/or
transmission stand.
1. Place transmission sprocket in position. Install the belt on
the sprocket as the sprocket is installed on the main drive
gear.
NOTES
• Exercise caution to avoid getting oil on the threads of the
sprocket nut or the integrity of the lock patch may be
compromised.
• The transmission sprocket nut has right-hand threads.
Turn the nut clockwise to install on the main drive gear.
2. See Figure 6-39. Install the sprocket nut. The following
procedure is based on whether a new or used nut is being
used.
a. New sprocket nut: spread a small quantity of clean
engine oil on the inside face of the sprocket nut and
the outside face of the sprocket. Limit the application
to where the surfaces of the two parts contact each
other. Install the sprocket nut until finger tight.
b. Used sprocket nut: apply Loctite High Strength
Threadlocker 271 (red) to the threads of the sprocket
nut. Also spread a small quantity of clean engine oil
on the inside face of the sprocket nut and the outside
face of the sprocket. Limit the application to where
the surfaces of the two parts contact each other.
Install the sprocket nut until finger tight.
3. See Figure 6-41. Lock transmission sprocket with the
FINAL DRIVE SPROCKET LOCKING TOOL (Part No. HD-
46282) (2). Final drive sprocket locking tool must rest
against upper portion of rear fork pivot nut (3).
4. Install PILOT (Part No. HD-94660-2) on mainshaft.
5. Using MAINSHAFT LOCKNUT WRENCH (Part No. HD-
47910) (1), tighten sprocket nut to 35 ft-lbs (47.5 Nm) initial
torque.
6. Loosen sprocket nut to remove initial torque.
7. Tighten sprocket nut to 35 ft-lbs (47.5 Nm).
Failure to use Main Drive Gear Remover and Installer can
cause premature failure of bearing and related parts.
(00540b)
8. See Figure 6-42. Scribe a line (3) on the transmission
sprocket nut (1). Continue the line on the transmission
sprocket (2) as shown.
9. Tighten the transmission sprocket nut an additional 35°
to 45°.
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,
tighten sprocket nut as necessary (up to the 45° maximum)
until sprocket and lockplate holes are in alignment.
12. See Figure 6-39. Install screws (1) through two of the four
holes in lockplate (2), then into two corresponding tapped
holes in sprocket (4).
NOTES
• The 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, you must use BOTH
screws when you install the lockplate.
13. Tighten screws to 84-108 in-lbs (9.5-12.2 Nm).
14. Install primary chain assembly. See 6.3 DRIVE COMPON-
ENTS.
NOTE
The gasket between the primary chaincase cover and chain-
case must be replaced each time the cover is removed. Failure
to replace this gasket may cause primary chaincase leaks.
15. Install primary chaincase cover. See 6.2 PRIMARY
CHAINCASE COVER.
16. Fill primary chaincase with lubricant. See 1.9 PRIMARY
CHAIN.
17. Verify pivot shaft torque. See 2.23 REAR FORK.
18. Adjust belt tension. See 1.13 REAR BELT DEFLECTION.
19. Verify vehicle alignment and tighten rear axle. See
2.11 VEHICLE ALIGNMENT.
20. Install debris deflector. See 2.19 BELT GUARD and
2.20 DEBRIS DEFLECTOR.
