Assembling - Husqvarna 545RXT AT Workshop Manual

Gear head

13.1 Assembling

1. Replace damaged parts.
2. Assemble the gear head in the opposite sequence
as set out for dismantling. See figure 6.
3. Fit the bearings on their respective axles. It is easier
if the bearings are heated to approx. 100°C.
Note: Do not forget the circlip holding the bearing on the
input axle. Make sure the bearings bottom in their seats.
4. Heat the gearbox to approx. 150°C and first lift the
output axle in position and then the input axle. Make
sure the bearings bottom in their seats.
5. Mount the circlips and make sure they lie correctly in
their grooves.
6. Rotate the axles and make sure that they rotate
easily without a tendency for the cogwheels to seize.
Fill the gearbox with special grease (See Service
tools, pos. 15). Wipe any excess grease from the
joint between the shaft and the gear head before the
gear is fitted to prevent it from turning around the
shaft.
7. Pry away the plastic sleeve (A) and the O-ring (B) on
the shaft using a knife. See figure 7.
8. When fitting, a new O-ring must be used. To avoid
damage from the sharp edges of the slits in the gear
housing, the following assembly procedure is
recommended:
• Slide the O-ring B onto the plastic sleeve.
• Place the plastic sleeve A in the tube unit.
• Slide the shaft into position.
Lubricate the drive axle with grease (See Service tools,
pos. 16) when assembling.
