CLUTCH

REMOVAL AND INSTALLATION

To remove the clutch without disassembly or for installation
instructions, see 

5.4 DRIVE COMPONENTS, Removal

.

CLUTCH PACK ONLY

Partial Disassembly

This procedure can be performed on the motorcycle without
removing the clutch shell or hub.

1.

Remove primary chaincase cover. See 

5.3 PRIMARY

CHAINCASE COVER, Removal

.

2.

See 

Figure 5-30

. Remove six bolts (1) (metric) to release

diaphragm spring retainer (2) from clutch hub. Loosen
each bolt gradually and in a star sequence around the
hub.

3.

Remove diaphragm spring retainer, diaphragm spring (3)
and pressure plate (4) from clutch hub.

4.

Remove friction plates (5, 7), steel plates (6), damper
spring (8) and damper spring seat (9) from clutch hub (11).
Continue with Cleaning And Inspection.

Cleaning And Inspection

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)

1.

Wash all parts in cleaning solvent, except for friction plates
and bearing, if removed. Blow parts dry with low pressure
compressed air.

2.

Check friction plates as follows:

a.

Blow off all lubricant from the friction plates. Do not
wipe off with a rag.

b.

Measure the thickness of each plate with a dial caliper
or micrometer.

c.

If the thickness of any plate is less than 0.143 in. (3.62
mm), discard all friction plates and replace with an
entirely new set.

d.

Look for worn or damaged fiber surface material (both
sides).

NOTE

Replace all nine friction plates with an entirely new set if any
individual plate shows evidence of wear or damage. Submerge
and soak all friction plates in FORMULA+ TRANSMISSION
AND PRIMARY CHAINCASE LUBRICANT (Part No. 99851-
05, qt.) for at least five minutes.

3.

Check the steel plates as follows:

a.

Discard any plate that is grooved or bluish in color.
Blue plates are likely warped or distorted.

b.

Check each plate for distortion. Lay the plate on a
precision flat surface. Insert a feeler gauge between
the plate and the flat surface in several places.
Replace any steel plate that is warped more than
0.006 in. (0.15 mm).

4.

Holding the clutch hub, rotate the clutch shell to check
bearing for smoothness. Replace the bearing if it runs
rough, binds or has any end play.

5.

Check the primary chain sprocket and the starter ring gear
on the clutch shell. Replace the clutch shell if either
sprocket or ring gear are badly worn or damaged.

6.

Check the slots that mate with the clutch plates on both
the clutch shell and hub. Replace shell or hub if slots are
worn or damaged.

7.

Check the diaphragm spring and diaphragm spring retainer
for cracks or bent tabs. Obtain a new diaphragm spring
or diaphragm spring retainer if either condition exists.

TRANSMISSION

POWER FLOW

See 

Figure 6-1

. The 6-speed transmission consists of two

parallel shafts supporting six gears each. The longer, or
mainshaft (7), also supports the clutch and serves as the input
shaft. The shorter shaft is called the countershaft (8).

Each gear on the mainshaft is in constant mesh with a corres-
ponding gear on the countershaft. Each of these six pairs of
gears makes up a different speed in the transmission.

The transmission gears are divided into two types, gears that
rotate with the shaft, and freewheeling gears that ride on
bearings and spin freely on the shaft. A gear that rotates with
the shaft always meshes with a freewheeling gear. Also, three
dog rings are able to slide sideways on the shaft. These dog
rings are used to change transmission speeds. The dogs, or
projections, on the sides of the dog rings, engage dogs on
adjacent freewheeling gears, transmitting power through the
transmission.

Gear shifting is accomplished by three forks which fit into
grooves machined into the dog rings that slide on the guide
hubs. The position of the shifter forks is controlled by a drum-
shaped shifter cam located in the transmission side door.

Neutral

Power is introduced to the transmission through the clutch. In
neutral, with the clutch engaged, the mainshaft 1st, 2nd, 3rd
and 4th gears are rotating, but no power is transferred to the
countershaft since countershaft 1st, 2nd, 3rd and 4th gears
are freewheeling gears.

1st Gear

When the transmission is shifted into first gear, the dog ring
between countershaft 1st and 2nd, which rotates with the
countershaft, engages countershaft 1st, which has been spin-
ning freely on the countershaft driven by mainshaft 1st.

Now countershaft 1st is no longer freewheeling, but locked to
the countershaft causing the countershaft and countershaft

6th to turn. Countershaft 6th transmits the power to the main
drive gear and the sprocket as shown (1).

2nd Gear

Second gear is engaged when the dog ring between counter-
shaft 1st and 2nd is shifted out of countershaft 1st and engages
countershaft 2nd. This locks countershaft 2nd to the counter-
shaft to complete the power flow as shown (2).

3rd Gear

Two shifter forks are used to make the shift from second to
third. One fork moves the dog ring between countershaft 1st
and 2nd to its neutral position, while another fork engages the
dog ring between countershaft 3rd and 4th with countershaft
3rd. This locks countershaft 3rd to the countershaft to complete
the power flow as shown (3).

4th Gear

Fourth gear is engaged when the dog ring between counter-
shaft 3rd and 4th is shifted out of countershaft 3rd and engages
countershaft 4th. This locks countershaft 4th to the countershaft
to complete the power flow as shown (4).

5th Gear

Two shifter forks are used to make the shift from fourth to fifth.
One fork moves the dog ring between countershaft 3rd and
4th to its neutral position, while another fork engages the dog
ring between mainshaft 5th and 6th with mainshaft 5th. This
locks mainshaft 5th to the mainshaft to complete the power
flow as shown (5).

6th Gear

The shift from fifth to sixth gear occurs when the dog ring
between mainshaft 5th and 6th is shifted out of mainshaft 5th,
and is shifted directly into the main drive gear (6th gear). The
main drive gear is locked to the mainshaft resulting in a direct
one-to-one drive ratio from the clutch to the sprocket as shown
(6).
