Bleeding The Cooling System; Replacing The Glassfiber Yarn Packing Of The Silencer; Cleaning The Spark Arrester - HUSABERG "05 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 bubbles.
Then, fill in the coolant until it reaches a level about 10mm above the radi-
ator 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 muffling power. By expe-
rience, 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 dismount 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 glassfiber 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 avai-
lable 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 fil-
ling is changed or at least once annually.
For this purpose, dismount the silencer cap and remove any deposits that
might exist in region (B). Renew the O-ring and mount the silencer cap.
