Section 6: Maintenance

Table of Contents
The frequency of needing to change the air filter is
largely determined by driving conditions. Dusty
conditions will require more frequent servicing.
A dirty filter element should always be replaced with a
new element. Improper cleaning procedures can get dust
on the inside of the filter causing dirt ingestion and
engine problems. The air filter warranty expires upon
cleaning or servicing a used filter in any manner.
Land Pride does not warranty a dust ingested engine
problem if a used air filter element has been cleaned
or serviced in any manner.
Improper Installation
Improper installation occurs when dust leaks past the
seals. The filter element must be aligned within the
canister and properly seated on both ends to prevent dirt
from entering the engine.
Damaged Air Filtering System
A damaged air filtering system often occurs from
mishandling the filter element and driving the vehicle in
areas that could damage the canister.
Banging and/or bumping the filter element against a solid
object such as a tire or blowing the element with air can
damage the seals and/or force dust and dirt particles
through the filter media creating a hole for dirt to pass
through to the engine.
Driving the vehicle carelessly over rough terrain, jutting
sticks, heavy brush and severe rocks can damage the air
cleaner canister. Periodically inspect the air cleaner
canister for external damage and replace if necessary.
Incorrect Air Filter Element
The air filter must remain intact to block passage of dirt
and foreign particles. It must be of sufficient size and
construction to withstand stresses, caused by rapid
cycling of air volume demanded by the engine, without
cracking or tearing under fatigue and pressure. Its filter
elements must have the correct media composition, filter
area, micron size and dimensions to properly filter the air
of dirt while at the same time passing sufficient air to the
engine.
Land Pride and the engine manufacturers have carefully
selected a reliable filter designed to fit the needs of the
Treker engines. Always specify a Land Pride filter part
number 839-323C.
Always use genuine Land Pride filters. Not using
original equipment replacement parts is an
alteration and will not be considered for warranty in
the event of a dust ingested engine problem.
CVT Snorkel Filter Maintenance
Refer to Figure 6-10:
Located under the seat on the passenger side are the
engine air intake snorkel and CVT air intake snorkel.
Inside the CVT snorkel is a filter element that should be
inspected at every oil change.
1.
Check filter element (#2) by removing it from CVT air
intake snorkel (#1) and inspecting it for dirt and
damage.
2.
If dirty, wash filter element in warm soapy water. Rinse
and let dry before reinstalling.
3.
Replace with a new filter element if torn or cut.
4.
Check all fittings and clamps periodically for tightness.
Inspect hose for holes or cracks.
