Cleaning With Pressure Air
1. Use clean, dry air- 40 PSI maximum. Hold the nozzle at least one inch from the element and at a slight angle. (A direct blast can rip the pleating).
CLEANING ELEMENT WITH AIR2. Direct the air stream along the complete length of each pleat on the CLEANEST side of the element. (This will loosen the dirt from the dirtier side.)3. Blow the loosened dirt from the DIRTY side.4. Direct the air from the CLEAN side through to the DIRTY side to remove dirt blown into the pleating.Cleaning With Water
1. Use clean water at no more than 40 PSI. Do not use a nozzle.2. Direct the water stream along the complete length of each pleat on the CLEAN side of the element.
CLEANING ELEMENT WITH WATER3. Direct water along the complete length of each pleat on the DIRTY side of the element.4. Rinse the CLEAN side of the element.5. Allow the cleaned element to dry thoroughly.Cleaning With Detergent
1. Wash both sides of the element in a solution of warm water and non-sudsing household detergent.2. Rinse the CLEANEST side of the element with clean water (40 PSI maximum) along the complete length of each pleat.
WASHING ELEMENT WITH DETERGENT3. Rinse the opposite side of the element along the complete length of each pleat.4. Rinse the first side again to remove all loosened dirt.5. Allow the cleaned element to dry thoroughly.Storing Cleaned Elements
1. Hold the dried element in front of a lighted electric bulb. Carefully inspect the element for tiny, pinpoints of light. Any light showing indicates a pleat has ruptured and will tear with further use. Discard the element.
INSPECTING ELEMENT2. Wrap usable elements in heavy paper.3. Store the wrapped element in a dry, clean place.Precleaner
Servicing
When the precleaner body is 3/4 full, remove and empty the precleaner. 1. Remove the dust collector cover.2. Remove and empty the dust collector body.3. If necessary, wash the dust collector in water.
AIR CLEANER PRECLEANEREngine Valve Lash
(D379, D398, D399 Engines)
Valve Lash
1. Stop the engine.2. Remove the flywheel housing timing cover.
REMOVING TIMING COVER3. Determine the direction of flywheel rotation. See the decal above the flywheel housing.
FLYWHEEL ROTATION DECAL4. Wipe dirt from the base of the valve covers.5. Remove the valve covers.6. Bar the flywheel in the direction of normal rotation. Align the "TDC 1" timing mark for your engine, ("TDC 1-7", "1'11", or "TDC 1-15"), with the timing pointer on the flywheel housing.
BARRING FLYWHEELChecking Adjustment
1. Observe the rocker arms for cylinder No. 1. Determine if the piston is on compression or exhaust stroke.Compression stroke: Both intake and exhaust valves are closed.Exhaust stroke: Intake valve is closed, exhaust valve is opened.
NUMBERING OF CYLINDERS AND VALVES2. With NO 1 CYLINDER ON COMPRESSION STROKE, check the lash of the following valves: Adjust if necessary. See the Lubrication and Maintenance Chart for correct valve lash.
CHECKING VALVE LASH3. Bar the flywheel one revolution in the direction of normal rotation. Align the "TDC 1" timing mark for your engine, ("TDC 1-7", "TDC 1-11" or "TDC 1-15"), with the timing pointer on the
