11. With the help of a second person, carefully remove
front and rear output shafts (items 35 and 38) along with
reverse and input shafts (Fig. 55 items 37 and 50) as a
complete assembly. The silent chains (Fig. 55 items 53
and 54) will keep the paired shaft assemblies together
(Fig. 61 and 62).
12.Carefully remove and discard all seals from front and
rear gear cases. Make sure that bores in cases are not
damaged during seal removal.
13.If necessary, remove button head screw that secures
speed sensor (Fig. 55 item 55) to rear gear case and
slide sensor from gear case. Remove and discard
O- ring from sensor.
14.Clean all sealant from mating surfaces of front gear
case, rear gear case ans sector gear (Fig. 55 item 26, 27
and 28).
15.Remove and discard O- rings (Fig. 55 items 60 and
51) from grooves in shift drum shaft and shift shaft.
16.Inspect park plate (item 34) that is secured to inside
of rear gear case. If plate is worn or damaged, remove
park plate from gear case and replace it.
17.Inspect shift drum (Fig. 55 item 29) for wear or dam-
age to bearing surfaces and to slots for shift fork pins. Al-
so, inspect threads and splines on shift drum shaft.
Replace shift drum if worn or damaged.
18.Inspect shift forks (Fig. 55 item 45) for any evidence
of wear or damage. Also, inspect shift shaft rail (Fig. 55
item 40) for evidence of bending or wear. Replace shift
fork(s) or shift shaft rail if necessary.
19.Carefully inspect all transmission shaft bearings,
gear teeth and shaft splines for wear or damage. If in-
spection identifies the need to replace any transmission
shaft components, proceed as follows:
NOTE: Use a press to remove bearings from transmis-
sion shafts. Discard and replace all removed bearings.
A. Front and rear output shafts can be separated by
removing the silent chain from the two (2) shafts.
Once these shafts are separated, shaft components
can be removed using Figure 55 as a guide.
B. To separate reverse and input shafts, the bearing,
park shift dog and 67 tooth gear (Fig. 55 items 20, 42
and 47) need to be removed from the reverse shaft to
provide needed clearance for removal of the silent
chain from the two (2) shafts (Fig. 63). Once these
shafts are separated, shaft components can be re-
moved using Figure 55 as a guide.
