Assembly
1.
Install the new input shaft into the splines of the drive
gear just far enough to expose the snap ring groove in
the ID of the drive gear.
2.
Install the snap ring in the ID of the drive gear.
3.
Install the washer on the shaft.
4.
Move the fourth-fifth speed sliding clutch gear forward to
contact the end of the input shaft in the hub of the drive
gear. Block between the rear of the sliding clutch and the
front of the fourth speed gear. When installing the
bearing this will hold the input shaft in position to seat
the bearing properly.
5.
Install the drive gear bearing on the shaft and into the
case bore. Ensure the blocking remains in place.
6.
Remove the blocking from the mainshaft and install the
drive gear bearing nut (left-hand thread). Use Loctite
sealant on the threads of the nut and shaft.
7.
Peen the nut into the milled slots in the shaft.
8.
Install the front bearing cover, shifting bar housing and
gear shift lever housing.
Installation of the Transmission
1.
Refer to
, page 7-24 in this section and install the
c l u t c h a s w e l l a s p e r f o r m t h e r e q u i r e d c l u t c h
maintenance.
2.
Put a very light film of wheel bearing grease on the input
shaft of the transmission.
3.
Attach an adequate lifting device to the transmission and
position the transmission so the transmission housing
aligns with the engine flywheel housing.
4.
Carefully move the transmission forward, ensuring the
shaft aligns with the splines on the clutch discs and the
clutch release yoke rides up and over the release
bearing while the shaft goes into the pilot bearing.
5.
Install the 12 bolts and washers mounting the clutch
housing to the engine flywheel housing. Torque per
specifications
6.
Install the bolts and washers securing the engine
flywheel to the flywheel ring cover.
7.
Refer to
, page 7-1 and install the engine
and transmission.
Lubrication
General
The transmission is designed so the internal parts operate in
a bath of oil circulated by the motion of gears and shafts.
Grey iron parts have built-in channels where needed, to help
lubricate bearings and shafts.
Thus, all parts will be amply lubricated if these procedures
are closely followed.
•
Maintain the oil level. Inspect regularly.
•
Change the oil regularly.
•
Use the correct grade and type of oil.
•
Buy from a reputable distributor.
Draining Oil
Drain the transmission while the oil is warm. Remove the
drain plug at the bottom of the case. Clean the drain plug
before installation.
Refilling Oil
Clean the area around the filler plug and remove the plug
from left side of the case. Fill the transmission to the level of
the filler openings. The exact amount of oil will depend on the
transmission inclination, always fill to the proper level using
sight plug. Do not overfill. This will cause oil to be forced out
of the case through the mainshaft opening.
Adding Oil
It is recommended that types and brands of oil not be
intermixed because of possible incompatibility.
Operating Temperature
It is important the transmission operating temperature does
not exceed 120°C (250°F) for an extended period of time.
Operating temperatures above 120°C (250°F) will cause
breakdown of the oil and shorten transmission life.
The following conditions in any combination can cause
operating temperatures of over 120°C (250°F).
•
Operating consistently at road speeds under 32 k/h (20
mph).
•
High engine rpm.
•
High ambient temperature.
•
Restricted air flow around the transmission.
•
Exhaust system too close to the transmission.
•
High horsepower, overdrive operation.
High operating temperatures may require more frequent oil
changes.
CAUTION
Risk of Damage!
Make sure the input shaft or clutch release yoke does not
bind on the release bearing.
