e. Install the dropcase cover retaining screws
and tighten to the torque listed in Table 2.
14. On models equipped with an external chain
tensioner, proceed as follows:
a. Install the chain tensioner housing assem-
bly (7, Figure 9) in the side of the dropcase.
Tighten the tensioner housing securely.
b. Unscrew the temporarily installed setscrew
in the side of the tensioner housing.
c. Reinstall the original capscrew (8, Figure
9).
15. Fill the dropcase with the amount and type
of gear oil specified in Chapter Three.
16. Adjust the shift linkage as follows:
a. If not previously removed, remove the drive
belt as described in Chapter Thirteen.
b. Rotate the driven pulley while turning the
shift fork arm toward the dropcase. Make
sure the transmission is fully in reverse.
c. With the transmission in reverse, rotate the
adjustment rod of the shift linkage until the
ball joint hole aligns with the hole in the
shift fork shaft arm.
d. Install and tighten the retaining screw and
locknut securely.
NOTE
Be careful. If the linkage is too short, the
shift fork shaft can be damaged. If the
linkage is too long, the gears will not
shift completely into reverse.
e. Shorten the linkage by rotating the adjust-
ment rod one additional tum. Lock the ad-
justment by tightening the jam nut.
f. Check the shifting. With the shift lever in
reverse, it should not be possible to rotate
the shift fork shaft arm further toward the
dropcase. If necessary, repeat substeps 16b-
e.
17. Install the drive belt and cover.
CHAPTER FOURTEEN
EXTERNAL CHAIN TENSIONER
Some models are equipped with an external
chain tensioner (Figure 9). The coil spring (3,
Figure 9) rotates an adjuster shaft (4), which
rotates the adjuster screw (5). The adjuster screw
contacts the tensioner spring (9), which forces
the pin (10) against the tensioner arm (12),
thereby maintaining chain tension.
To service the internal components of the
chain tensioner, remove the dropcase cover as
discussed in the previous section. To service the
tensioner housing assembly, proceed as follows.
Removal
1. Remove the screw (8, Figure 9) and install a
setscrew in place of the original screw. Tighten
the setscrew sufficiently to hold the adjuster shaft
in position.
2. Remove the adjuster assembly by turning the
housing (7, Figure 9) counterclockwise using a
3/4-inch wrench.
Disassembly
1. Extract the pin (10, Figure 9) and the spring
(9) from the housing.
2. Hold the cover (2, Figure 9), then remove the
screws (1) securing the cover (2) to the housing
(7). Release the cover and allow the spring to
unwind.
