14. Reassemble the shifter by reversing the disassembly
procedure. Note the following during reassembly:
a. Apply sealant to the detent setscrew threads.
b. Install the shift lever on the shift shaft while align-
ing the marks made during disassembly.
c. If no alignment marks are available when installing
the shift lever, rotate the shift shaft so the shifter
bore is down as shown in Figure 23. The shift shaft
should engage the neutral detent. Install the shift le-
ver at a 45° angle as shown in Figure 23.
d. Install the shift lever on the shift shaft so the side
clearance between the lever and body is approxi-
mately 0.5 mm (0.020 in.).
Shifter (KM2P and KM3P models)
Refer to Figure 24.
1. If not previously removed, remove the control cable
connector from the shift lever.
2. Remove the shifter and spring.
3. Remove the stop bolt and shims.
4. Loosen the clamp bolt and remove the shift lever.
5. Remove the shifter shaft.
6. Remove and discard the O-ring.
7. Use a screwdriver or suitable tool to pry out the seal.
Be careful not to damage the bearing.
8. Inspect the shift shaft. Check the detent pin for damage
and excessive wear. If necessary, replace the detent pin.
Measure the shifter shaft bore in the shift shaft and com-
pare with the specifications in Table 7.
9. Inspect the body for galling, scoring or other damage
to the bore. Inspect the detents for damage and excessive
wear that will cause poor clutch engagement (Figure 25).
10. Inspect the spring for deformation or other damage.
Specified spring free length is 22.6 mm (0.89 in.). Mini-
mum spring length is 19.8 mm (0.78 in.).
II. Inspect the stop bolt. Replace it if it is excessively
worn.
12. Inspect the shifter. Measure the large diameter of the
shifter shaft and compare it with the specifications in Ta-
ble 7.
13. Reassemble the shifter by reversing the disassembly
procedure, but do not install the stop bolt until final instal-
lation of the shifter assembly on the transmission.
14. Reassemble the shifter by reversing the disassembly
procedure. Note the following during reassembly:
a. Do not install the stop bolt until final installation of
the shifter assembly on the transmission.
b. Rotate the shift shaft so the detent pin engages the
neutral detent (Figure 25). On the KM2P transmis-
sion, install the shift lever so the side with the trian-
gle mark (A, Figure 26) is out. On. the KM3P

transmission, install the shift lever so the side with
the triangle mark is toward the shifter body. With
the shift shaft in neutral, position the shift lever at a
45° angle as shown in Figure 26 and tighten the
clamp bolt.
REASSEMBLY
NOTE
On KM2P and KM3P transmissions, refer
to the Bearing Adjustment section prior to
reassembly
if
the following components
have been replaced: input shaft, input shaft
bearings, output shaft, thrust washers and
output shaft bearings.
I. If removed, install the outer bearing races into the
transmission case and mounting flange.
2. Apply sealer to the outside diameter ofthe oil seals and
install them into the transmission case and mounting
flange with the open side to the inside.
3. Install the input shaft into the transmission case.
4. Install the intermediate shaft assembly into the trans-
mission case. Install a new O-ring on the intermediate
shaft. Use a soft-faced hammer to tap the shaft into the
case.
5. While holding the input shaft out of the way, insert the
output shaft assembly into the transmission case. Move
the gears into mesh on the intermediate shaft, input shaft
and output shaft while installing the output shaft.
6. Ifthe following components have been replaced, refer
to the Bearing Adjustment section: input shaft, input shaft
bearings, output shaft, thrust washers and output shaft
