4-8. Spring Loaded Air Cleaner Filter Element (Fig. 4-13)
Figure 4-13. Spring-loaded air cleaner filter element.
An improved spring-loaded filter element is available that has increased dust capacity.
This greater dust capacity provides greater mileage between cleanings. It also provides a
more positive seal,
through the use of spring loaded locking pins, that reduces the
possibility of dust ingestion.
