Clutch Disassembly on Motorcycle

This procedure describes disassembly of the clutch while

it is mounted on the motorcycle. Engine sprocket and pri-
mary chain removal is not required. Read this procedure
completely before starting disassembly.

1. Disconnect the negative battery cable (Chapter Twelve).

2. Remove the primary drive cover as described in this
chapter.

WARNING

Do not attempt to disassemble the clutch
without using a clutch spring compression
tool. (

Figure 30

[part No. HD-38515A, part

No. 38515-90/91 or equivalent]). The dia-
phragm spring snap ring (12,

Figure 29

) is

held under considerable pressure and will fly
out if pressure is not first removed.

3. To remove the diaphragm spring snap ring, perform the
following:

a. Thread the clutch spring compression tool forcing

screw onto the clutch adjusting screw as shown in
Figure 38.

b. Position the spring compression tool (Figure 39)

against the diaphragm spring and thread the tool han-
dle onto the end of the forcing screw.

CAUTION

Turn the cltuch compression tool handle only
the amount required to compress the dia-
phragm spring and remove the snap ring. Ex-
cessive compression of the diaphragm spring
may damage the clutch pressure plate.

c. Hold the compression tool forcing screw with a

wrench (Figure 40) and turn the tool handle clock-
wise to compress the diaphragm spring.

d. Remove the snap ring (Figure 41) and spring seat

(Figure 42) from the groove in the clutch hub.

e. Remove the diaphragm spring, pressure plate, clutch

adjusting screw and spring compressing tool as an as-

NOTE

Do not loosen the spring compressing tool to
remove the diaphragm spring or pressure
plate unless these parts require close inspec-
tion or replacement. Loosening and removing
the clutch compression tool requires reposi-
tioning of the diaphragm spring during reas-
sembly. This step will not be required as long
as the compression tool is not removed from
these parts.

4. Remove the friction and steel clutch plates (Figure 44)
and the spring plate, from the clutch assembly in the order
shown in Figure 29. Note the spring plate installed between
the fourth and fifth friction plates (Figure 45).

NOTE

Further removal steps are not required unless
it is necessary to separate the clutch hub and
shell assembly. Remove these parts as de-
scribed in

Clutch Hub and Shell Disassem-

bly/Reassembly

in this section.

Clutch Inspection

1. Clean all parts, except friction plates and bearings, in a
non-oil based solvent and thoroughly dry with compressed
air. Place all cleaned parts on lint free paper towels.
2. Check each steel plate (A, Figure 46) for visual damage
such as cracks or wear grooves. Then place each plate on a
surface plate, such as piece of glass, and check for warp

with a feeler gauge. Replace the steel plates as a set if any
one plate is warped more than 0.006 in. (0.15 mm).

3. Inspect the friction plates (B, Figure 46) for worn or
grooved lining surfaces. Replace the friction plates as a set if
any one plate is damaged. If the friction plates do not show vi-
sual wear or damage, wipe each plate thoroughly with a
lint-free cloth to remove as much oil from the plates as possi-
ble. Measure each plate individually and compare to the mea-
surements in Table 1. Stack each of the eight friction plates on
top of each other and measure the thickness of the assembly.
Replace the friction plates as an assembly if the combined
thickness of the eight plates is less than 0.661 in. (16.79 mm).

4. Measuer each steel plate and compre the thickness to the
specification in Table 1. Replace if not within specification.

5. Check the spring plate (C, Figure 46) for cracks or dam-
age. Check for loose or damaged rivets. Replace the spring
plate if necessary.

6. Check the clutch diaphragm spring for cracks or dam-
age. Check also for bent or damaged tabs. Replace the dia-
phragm spring if necessary.

7. A ball bearing is pressed into the clutch shell and the
clutch hub is pressed into the bearing. Hold the clutch hub
and rotate the clutch shell by hand. The shell should turn
with no sign of roughness or tightness. If the clutch shell
binds or turns roughly, the bearing is damaged and must be
replaced. Refer to Step 10.

8. The steel clutch plate inner teeth mesh with the clutch
hub splines. Check the splines for cracks or galling. They
must be smooth for chatter-free clutch operation. If the
clutch hub splines are damaged, the clutch hub must be re-
placed; refer to Step 10.

9. The friction plates (B, Figure 46) have tabs that slide in the
clutch shell grooves. Inspect the shell grooves for cracks or
wear grooves. The grooves must be smooth for chatter-free
clutch operation. If the clutch shell grooves are damaged or
worn severely, replace the clutch shell; refer to Step 10.

10. Check the primary chain sprocket and the starter ring
gear on the clutch shell for cracks, deep scoring, excessive
wear or heat discoloration. If either the sprocket or ring gear
is severely worn or damaged, replace the clutch shell; refer to
Step 11. If the sprocket is worn, also check the primary chain
and the engine sprocket as described in this chapter.

11. If the clutch hub, shell or bearing require replacement,
refer to

Clutch Hub and Shell Disassembly/Reassembly

in

this section.

Primary Chain

Replace the primary chain if severely worn or damaged.

Do not attempt to repair the chain. If the primary chain is
worn or damaged, check the engine sprocket and clutch shell
sprocket for wear or damage. Replace parts as required.

Clutch Hub and Shell
Disassembly/Reassembly

The clutch hub and shell should not be separated unless

replacement of the hub, shell or bearing is required. Disas-
sembly of the hub and shell will damage the ball bearing;
bearing replacement will be required during reassembly.

A press is required for this procedure.

1. Remove the clutch plates from the clutch hub and shell
assembly, if they have not been previously removed. Refer
to

Clutch Disassembly on Motorcycle

in this section.

2. Remove the snap ring from the clutch hub groove (Fig-
ure 47).
3. Support the clutch hub and shell in a press (Figure 48)
and press the clutch hub out of the bearing. See Figure 49.
Remove the clutch shell from the press.
4. Locate the snap ring (Figure 50) securing the bearing in
the clutch shell and remove it.
5. The bearing must be removed through the front side of
the shell. The clutch shell is manufactured with a shoulder
on the rear (primary chain) side. Support the clutch shell in
the press and press the bearing out of the shell. Discard the
bearing.
6. Discard worn or damaged parts. Clean reusable and new
parts, except bearings and snap rings, in non-oil based sol-
vent and dry thoroughly.
7. Place the clutch shell into the press. Align the bearing
with the clutch shell and press the bearing into the shell un-
til the bearing bottoms out against lower shoulder. When
pressing the bearing into the clutch shell, press only on the
outer bearing race. Refer to

Service Procedures

in Chapter

One for additional information.
8. Install a new bearing snap ring into the clutch shell
groove (Figure 50). Make sure the snap ring seats in the
groove completely.
9. Press the clutch hub into the clutch shell as follows:

CAUTION

Failure to support the inner bearing race
properly will cause bearing and clutch shell
damage. Refer to

Figure 51

to make sure the

inner hearing race is supported properly.

a. Place the clutch shell in a press. Support the inner

bearing race with a sleeve as shown in Figure 51.

b. Align the clutch hub with the bearing and press the

clutch hub into the bearing until the clutch hub shoul-
der seats against the bearing.

c. Install a new clutch hub snap ring (Figure 47). Make

sure the snap ring seats in the clutch hub groove com-
pletely.

10. After completing assembly, hold the clutch hub and ro-
tate the clutch shell by hand. The shell should turn
smoothly with no roughness or binding. If the clutch shell
binds or turns roughly, the bearing may have been damaged
during reassembly. Correct before installing.

Clutch Assembly

After assembly, the clutch will be installed back onto the

motorcycle. If the clutch assembly was not disassembled,
refer to

Clutch Installation

in this section.

Refer to Figure 29.

NOTE

Before installing the clutch plates, count the
number of each plate. The set should include
eight friction plates, six steel plates and one
spring plate.

1. Soak all of the clutch plates in clean transmission oil for
approximately 5 minutes before installing them.
2. Align the tabs on a friction plate with the clutch shell
grooves and install the plate. Then align the inner teeth on a
steel plate with the clutch hub grooves and install the plate.
Repeat until all of the clutch plates have been installed. In-
stall the spring plate (Figure 45) between the fourth and
fifth friction plates. The last plate installed must be a fric-
tion plate.

NOTE

During clutch removal, if the spring com-
pressing tool was not removed from the dia-
phragm spring and pressure plate, proceed to
Step 4. If the spring compressing tool was re-
moved and the clutch diaphragm spring was
separated from the pressure plate, continue
with Step 3.

3. Assemble the pressure plate and clutch diaphragm
spring as follows:

a. Install the adjusting screw assembly (release plate,

snap ring, bearing and adjusting screw) into the pres-
sure plate. Install the release plate by aligning its tabs
with the slots in the pressure plate. Secure the release
plate by installing the retaining ring into the pressure
plate groove. Make sure the retaining ring seats in the
groove completely.

b. The diaphragm spring is concave. Install the dia-

phragm spring onto the pressure plate so the concave
side faces the pressure plate—the convex side must
face out.

c. Install the spring seat with its flat, larger outer diame-

ter side facing toward the diaphragm spring.

WARNING

Because of the force required to compress the
diaphragm spring when installing the snap
ring, a clutch spring compression (part
No.HD-38515A, 38515-90/91 or equivalent)
must be used. Severe personal injury from the
diaphragm spring flying out could occur if
the special tool is not used.

4. To install the diaphragm spring snap ring, use a clutch
spring compression tool to perform the following:

a. Thread the spring compression tool forcing screw

onto the clutch adjusting screw.

b. Position the spring compression tool against the dia-

phragm spring and thread the tool handle onto the
end of the forcing screw. Do not apply pressure
against the diaphragm spring at this time.

c. Align the square holes in the pressure plate and dia-

phragm spring with the prongs on the face of the
clutch hub. Then place the spring seat, snap ring, dia-
phragm spring, pressure plate, adjusting screw as-
sembly and compressing tool onto the clutch hub
(Figure 43).

CAUTION

Turn the compression tool handle only the
amount required to compress the diaphragm
spring and install the snap ring. Excessive
compression of the diaphragm spring may
damage the clutch pressure plate.

d. Hold the compression tool forcing screw with a

wrench and turn the tool handle clockwise to com-
press the diaphragm spring.

e. Install the spring seat and snap ring into the groove in

the clutch hub.

f. After making sure the snap ring is seated completely

CHAPTER EIGHT

FOUR-SPEED TRANSMISSION

(1986-1990 MODELS)

This chapter covers the four-speed transmission, internal

gearshift assemblies and shift mechanism. Tables 1-8 are at
the end of this chapter.

When the clutch is engaged, the mainshaft is driven by

the clutch hub, which is driven by the primary chain
sprocket/clutch outer housing. Power flows from the
mainshaft through the selected gear combination to the
countershaft, which drives the main drive gear and trans-
mission sprocket.

To gain access to the transmission and internal shift

mechanism, it is not necessary to remove the engine or dis-
assemble the crankcase. The transmission components are
contained behind an access door on the left crankcase half.

TRANSMISSION

Transmission Removal

1. Drain the transmission/primary drive oil (Chapter
Three).
2. Remove the clutch and primary chain (Chapter Six).
3. Remove the drive sprocket (Chapter Thirteen).
4. Remove the stator (Chapter Twelve).
5. Remove the thrust washer (Figure 1).
6. Remove the transmission access cover bolts. See Figure 2.
7. Remove the access cover (Figure 2) with the transmis-
sion and shift mechanism assembly attached. See Figure 3.

8. Remove the shift lever (Figure 4).

Transmission Installation

1. Install the shift shaft into the crankcase so that the shift
lever arm is centered as shown in Figure 5.

NOTE

Mark the shift shaft at the 12 o’clock position
as shown in

Figure 6

. Marking the shaft pro-

vides a reference mark to determine if the shift
lever arm position changes when installing
the transmission.

2. Install the transmission access cover (Figure 3). Then
rotate the countershaft to check the shift shaft is engaged
with the shifter pawl. To do so, lightly rotate the shift shaft.
A noticeable resistance to movement indicates proper
engagement.
3. Install the access cover bolts (Figure 2). The short bolt
must be installed in the upper right hole. Tighten all access
cover bolts to 14-19 ft.-lb. (19-26 N•m).

CAUTION

Do not use the old stator Torx screws. New
Torx screws have a pellet formed locking
compound on their threads. When new Torx
screws are installed, the pellet breaks and

releases the locking compound on the bolt
threads. The locking compound on the old
bolts cannot be reused; if installed, the old
bolts may loosen during engine operation.

4. Install the alternator stator as described in Chapter
Twelve.
5. Install the clutch (Chapter Six).
6. Install the drive sprocket (Chapter Thirteen).
7. Install the rear chain. Adjust it as described in Chapter
Three.
8. Refill the transmission/primary oil (Chapter Three).

Transmission Disassembly

Refer to Figure 7.

1. Pull the mainshaft assembly (Figure 8) from the clutch
gear.
2. Remove the following from the countershaft:

a. First gear washer (Figure 9).
b. First gear (Figure 10).
c. Third gear washer (Figure 11).

3. Remove the shift fork shaft (Figure 12).
4. Remove the shift fork (Figure 13) from the countershaft
third gear.
5. Remove the finger rollers (Figure 14) from the shift fork.
6. Remove countershaft third gear (Figure 15).
7. Remove mainshaft second gear (Figure 16).
