POWER TRAIN RT9130E SERVICE MANUAL
Cleaning With Compressed Air
1. Direct a jet of clean, dry air from the inside of the filter
element, perpendicular to the pleats (Figure 7-8).
2. Move the air jet up and down along the pleats, slowly
rotating the element, until no more dust is being
removed. Do not rupture the element with the nozzle or
the air jet.
Cleaning With Water
1. The elements can be cleaned by washing with water and
a good non-sudsing detergent. Direct a jet of clean, dry
air from the inside of the filter element. Wash the
element after the loose dust and soot are removed
(Figure 7-9).
2. Dissolve the detergent in a small amount of cool water.
3. Add warm water (approximately 38°C [100°F]) to get the
proper proportions of detergent and water (about one
cup of detergent to five gallons of water).
4. Soak the element for at least 15 minutes.
5. Agitate the element for about two minutes to loosen the
dirt.
6. Rinse the element with clean water until the water
coming through the element is clean. Air-dry the element
thoroughly before using (Figure 7-10).
7. Mechanized drying methods can be used.
Inspection
Element
After cleaning the filter element, inspect the element for
damage. Look for dust on the clean air side, the slightest
rupture, or damaged gaskets. A good method to use to
detect ruptures in the element is to place a light inside the
element and look toward the light from the outside. Any hole
in the element will pass dust to the engine and cause
unnecessary engine wear. Replace the element if holes are
evident (Figure 7-11).
CAUTION
Pressure at the air nozzle must not exceed 690 KPA
(100 PSI).
CAUTION
Never use gasoline or solvents to clean the elements.
CAUTION
Water pressure from a hose or tap should not exceed
276 kPa (40 PSI).
CAUTION
Heated air (maximum temperature 71°C [160°F]) must
have circulation. Do not use light bulbs for drying
elements.
CAUTION
Do not touch the inside of the filter with a bare light bulb.
