Spark Arrestor
WARNING
Failure to heed the following warnings while servicing the spark
arrestor could result in serious injury or death.
Do not perform service on the spark arrestor while the system is
hot. Exhaust system temperatures can reach 1000° F. A llow
components to cool sufficiently before proceeding.
Remove any combustible materials from the area. Wear eye
protection and leather work gloves. Do not stand behind or in
front of the vehicle while purging. Never run the engine in an
enclosed area. Exhaust contains poisonous carbon monoxide
gas. Never go under the vehicle while it’s inclined.
Use the following procedure to periodically purge accumulated carbon
from t he exhaust pipe/mufflers.
1. Remove the arrestor clean-out
plugs (1) from the bottom
of the mufflers.
2. Place the transmission in
PARK and start the
engine.
3. Purge carbon from the
system by momentarily
revving the engine
several times.
4. If carbon is expelled, cover or
plug the exhaust outlets (2) and rap
on the pipes around the cleanout plugs
while revving the engine several more times.
5. If particles are still suspected to be in the mufflers, elevate t he rear
of the vehicle one foot higher than the front. Set the parking brake
and block the wheels. Make sure the vehicle is in PARK and
repeat steps 3 and 4 until no more particles are expelled when the
engine is revved.
6. Stop the engine and allow the arrestors to cool. Reinstall the
arrestor plugs and remove the outlet covers or plugs.
