Grease for gear housing:
Exxon Mobilgrease 28.
Husqvarna art.no: 525 58 35-01.
Amount 350 g.
Dividing the gear housing
Start by performing steps 1–7 in the previous section.
1. The gear selector must first be removed. This has a
locking screw, 3 mm Allen key, which is accessible
through a hole in the gear housing cover. Set the gear
selector lever to "HI" to reach the screw with the tool.
Loosen the locking screw a few turns and pull out the
gear selector.
2. The division is greatly simplified if the gear housing
cover is heated to about 100 °C/200 °F. The bearings
then release with a little force from the cover.
3. There are two break slots between cover and gear
housing. Insert suitable screwdrivers in these and work
off the cover alternately using the screwdrivers.
Gear housing appearance after division
Depending on the variations to the press-fitting between
shafts and bearings, the components may have a diffe-
rent position after the division, i.e. the two lower shafts
could just as well be located in the gear housing and not
as pictured on the cover.
Between the gear housing and the cover there is a
gasket that is missing in the illustrations. This must
always be replaced following dismantling.
Dismantling of the gear housing components is
described later in the manual.
Note: The bearing housing is filled with a large amount
of grease which for the sake of clarity has been removed
in the illustrations.
Gear housing – grease
The gear housing is filled with a generous amount of
grease that does not need to be replaced over the lifetime
of the machine.
If individual components are replaced/adjusted in the
gear housing, it is sufficient to move the grease to the
component being fixed. Exception: if an accident has
led to contamination of the grease with metal shavings,
the gear housing must be cleaned and the old grease
must be replaced with new.
Original grease: Exxon Mobilgrease 28 (Synthetic
Aviation Grease). Quantity: 350 g. Grease is sold as
spare part, art.no. 525 58 35-01.
Connection box – electricity
Remove the three screws that hold the connection box.
Press the box slightly towards the spindle shaft to release
the hooks. Lift up the connection box.
