Air Inlet and Exhaust System

- Inspect
A general visual inspection should be made to the air
inlet and exhaust system. Make sure that there are
no signs of leaks in the system.
There will be a reduction in the performance of the
engine if there is a restriction in the air inlet system or
the exhaust system.
Hot engine components can cause injury from
burns. Before performing maintenance on the
engine, allow the engine and the components to
cool.
Making contact with a running engine can cause
burns from hot parts and can cause injury from
rotating parts.
When working on an engine that is running, avoid
contact with hot parts and rotating parts.
1. Inspect the engine air cleaner inlet and ducting
in order to ensure that the passageway is not
blocked or collapsed.
2. Inspect the engine air cleaner element. Replace a
dirty element with a clean element.
3. Check for evidence of dirt on the clean side of the
engine air cleaner element. If dirt is observed,
contaminants are flowing past the element.

engine, allow the engine and the components to
cool.
Keep all parts clean from contaminants.
Contaminants may cause rapid wear and shortened
component life.

not adjusted.
1. Use a suitable dial indicator (1). Align the dial
gauge to the actuator rod (2).
2. Remove the air hose to the actuator . Install an air
line (3) that can be adjusted in order to give the
