c. Disconnect the pawl spring (Figure 65) and remove

the pawl (Figure 66).

d. Repeat for the opposite pawl.

9. Inspect the shift mechanism as described in this section.

10. Assembly is the reverse of disassembly, noting the fol-
lowing.

a. Install pawls on the pawl carrier, using spacers so that

the spring hook holes align. Note that one spacer will
be underneath the pawl and the other spacer will be
on outside of the pawl. See 26 and 31, Figure 57. Re-
tract one pawl. at a time, then install the shifter cam
into pawl carrier.

b. Install the assembly into the pawl carrier support so

that the ear of the pawl is between the ends of the
pawl carrier springs.

c. Install a new E-clip and washer.
d. Make sure that the pawls engage the cam ratchet.

Inspection

1. Clean all parts in solvent, then blow dry.
2. Examine the shifter cam for worn or grooved cam slots
(A, Figure 67). Excessive wear will result in difficult shift-
ing.
3. Check the shifter cam gear (B, Figure 67) for wear or
damage.
4. Examine the pawl carrier yoke (Figure 68) where it en-
gages the lever arm shaft. A severely worn yoke will cause
the transmission to jump out of gear.

5. Replace the pawl spring(s) if it is longer than 1.75 in.
(44.4 mm) between hooks.
6. Examine the shifter pawls (Figure 69) for grooves,
cracks, wear or breaks. Replace if necessary.
7. Examine the pawl carrier springs (Figure 70) for fatigue
or breaks. Replace them if they are shorter than 2.6562 in.
(67.467 mm). See Figure 71.
8. Check the pawl carrier support (Figure 72) for breaks or
minute surface cracks.
9. Check cam follower (11, Figure 57) for wear, especially
on its thrust surfaces.
10. Check the shift lever for bending or wear.
11. Loosely assemble the shifter cam, pawl carrier and the
pawl carrier support. After assembly, check bearing action
for play.

CHAPTER NINE

FIVE-SPEED TRANSMISSION

(1991-2003 MODELS)

This chapter covers the five-speed transmission, internal

gearshift assemblies and shift mechanism. Tables 1 and Ta-
ble 2 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
disassemble the crankcase. The transmission components
are contained behind an access door on the left crankcase
half.

Inspection

The manufacturer does not provide dimensional or ser-

vice specifications.

Replace parts that are excessively worn or damaged as

described in this section.
1. Clean all components in solvent and dry with com-
pressed air.

NOTE

Defective gears should be replaced. It is a
good idea to replace the mating gears as a set.

2. Check each gear tooth for excessive wear, burrs, galling
and pitting. Check each gear for missing teeth. Make sure
the gear lugs are in good condition.
3. Install each splined gear (Figure 63) on its respective
shaft and check for excessive play or binding.
4. Check each sliding gear (Figure 64) for scoring, galling
or seizure marks. Spin the gear on its shaft; it should turn
freely.
5. Check the groove in each sliding gear (Figure 63) for
severe wear or damage. If the groove is worn or damaged,
check the mating shift fork for damage. Replace the gear if
necessary.
6. Check the bearing surface on each shaft. These surfaces
must be smooth. See Figure 65 and Figure 66.
7. Check the shaft splines (Figure 67) for severe wear or
damage.
8. Inspect the snap ring grooves (Figure 68) in each shaft.
Each groove must have sharp square shoulders. If any are
worn or damaged, the shaft(s) must be replaced. See the
damaged splines in Figure 69.
9. Check the split bearings (Figure 70) for severe wear or
damage.
10. Check the thrust washers for galling, scoring, cracks or
other damage. If the washers are not smooth, replace them.
11. Check the countershaft (Figure 65) and mainshaft
(Figure 66) for bending, damaged splines or other abnor-
mal wear.

Assembly

Refer to Figure 40.

CAUTION

Replace all snap rings to ensure proper gear
alignment and engagement. Do not expand a
snap ring more than necessary to slide it over
the shaft.

1. Apply a light coat of new transmission oil to all sliding
gear and shaft sliding surfaces and split bearings (Figure
70) prior to installing any part.
2. If removed, install the access door bearings as described
in this chapter.
3. Press the mainshaft into its bearing as follows:

CAUTION

The bearing driver must press against the in-
ner bearing race or bearing damage results.

a. Place a bearing driver (A, Figure 71)in a press that

matches the mainshaft bearing inner race diameter.
Place the bearing inner race on the driver so that the
access door inner surface faces up as shown in B,
Figure 71.
