Typical service indicator
Observe the service indicator. The air cleaner
element should be cleaned or the air cleaner element
should be replaced when one of the following
conditions occur:
• The yellow diaphragm enters the red zone.
• The red piston locks in the visible position.
Test the Service Indicator
Service indicators are important instruments.
• Check for ease of resetting. The service indicator
should reset in less than three pushes.
• Check the movement of the service indicator core
when the engine is run at full load speed. The core
should latch approximately at the greatest vacuum
that is attained.
If the service indicator does not reset easily, or if the
core does not latch at the greatest vacuum, the
service indicator should be replaced. If the new
service indicator will not reset, the hole for the service
indicator may be plugged.
If necessary, replace the service indicator more
frequently in environments that are severely dusty.
Replace the service indicator annually regardless of
the operating conditions. Replace the service
indicator when the engine is overhauled, and
whenever major engine components are replaced.
Note:
When a new service indicator is installed,
excessive force may crack the top of the service
indicator. Tighten the service indicator to a torque of
2 N·m (18 lb in).
