Bleeding The Cooling System; Replacing The Glassfiber Yarn Packing Of The Silencer; Cleaning The Spark Arrester - HUSABERG Edition 2004 Owner's Manual

MAINTENANCE WORK ON CHASSIS AND ENGINE

BLEEDING THE COOLING SYSTEM

The cooling liquid is drained by removing the hose (1) from the
water pump.
To bleed the cooling system, fill in approx. 1 liter (0.26 US gallons)
of coolant and remove the bleeder screw (2). Do not reinstall the
bleeder screw until coolant escapes at the bore without any bub-
bles.
Then, fill in the coolant until it reaches a level about 10mm above
the radiator fins. After a short ride, check the coolant level once
more.
REPLACING THE GLASSFIBER YARN PACKING
OF THE SILENCER *
Aluminum silencers are filled with glassfiber yarn to muffle noise.
The effect of heat causes the glassfiber yarn to become loose. This
may lead to a loss of performance and reduce the silencer's muf-
fling power. By experience, the front glassfiber yarn packing (3)
needs to be replaced more often than the rear silencing mat (4).
For this purpose, remove the silencer from the vehicle and dismo-
unt the front cap (5). Pull the front glassfiber yarn packing together
with the inner exhaust pipe (6) out of the silencer. Clean the front
inner exhaust pipe.
To facilitate the mounting procedure, you can make a mounting
tool (7) out of wood, plastic, or metal. Insert the mounting tool into
the inner pipe and mount the glassfiber packing. Push the inner
pipe containing the packing into the silencer such that the slot
engages the web (A). Use a blunt ended object to stuff the glassfi-
ber yarn packing all the way into the silencer, and mount the front
cap (C).
To change the rear silencing mat, start by removing the front
packing and the inner exhaust pipe. Then, drill open the rivets and
remove the end cap.
NOTE: In every exhaust repair procedure, the O-rings
must be replaced by new ones. Glass fiber yarn packings
are available from your licensed Husaberg mechanic.
WARNING: The exhaust system becomes very hot while
the motorcycle is running. to avoid burns do not start
work on the exhaust system until it has properly cooled
down.

CLEANING THE SPARK ARRESTER *

The spark arrester should be cleaned every time the glassfiber yarn
filling is changed or at least once annually.
For this purpose, dismount the silencer cap and remove any depo-
sits that might exist in region (B). Renew the O-ring and mount the
silencer cap.
