Engine Air Precleaner - Check/Clean
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 yellow core when
the engine is accelerated to the engine rated
speed. The yellow core should latch at the greatest
vacuum that is attained.
If the service indicator does not reset easily, or if the
yellow 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 restricted.
The service indicator may need to be replaced
frequently in environments that are severely dusty.
