ENGINE AIR CLEANER MAINTENANCE —
TIER 3 ENGINE
Servicing the engine air cleaner is an important maintenance
function:
• A clogged air cleaner filter will prevent adequate air flow
to the engine, resulting in poor starting and increased
exhaust emissions.
• An improperly installed or damaged air cleaner can
allow dirty air to be drawn directly into the engine.
Either condition can result in engine damage.
Inspection
See Figure 7-7 for the following procedure.
To maintain engine protection and filter service life, inspect
the following areas at regular intervals:
Daily
Check service indicator daily with engine running.
• Yellow flag in indicator rises as filter fills with dirt.
Replace filter when yellow flag rises to red ring at
top of indicator and locks in place with engine off.
• Push button in on bottom of indicator to reset flag after
filter is replaced.
Daily
1. Inspect rubber elbows and tubes between air cleaner
and engine for cracks or other damage which might
allow unfiltered air to enter engine. Replace worn parts.
2. Check air cleaner housing for dents or other damage
that may allow unfiltered air to enter engine. Replace
housing if damaged.
3. Check for loose tubing clamps and pre-cleaner clamps.
Tighten loose parts.
4. Check that pre-cleaner is free of obstructions.
5. Check that ejector valve is in place in pre-cleaner dust
bin. Check that valve is in a good, soft, pliable condition
and replace valve if damaged.
