Cleaning Crankcase Vent Tube
If you operate the engine in dusty conditions, clean the tube at shorter intervals.
1. Remove and clean crankcase vent tube.
2. Install the vent tube. Be sure the O-ring fits correctly in the rocker arm cover for
elbow adapter.
Replacing Fuel Filter Elements
Engine is equipped with a primary fuel filter (or pre-filter) with water bowl and a final filter. Both
filters are replaced at the same 500-hour interval.
CAUTION
!
Escaping fluid under pressure can penetrate the skin causing serious
injury. Relieve pressure before disconnecting fuel or other lines. Tighten
all connections before applying pressure. Keep hands and body away
from pinholes and nozzles which eject fluids under high pressure. Use a
piece of cardboard or paper to search for leaks. Do not use your hand.
1. Close fuel shut-off valve, if equipped.
2. Thoroughly clean fuel filter assemblies and surrounding areas.
3. Disconnect water sensor wiring (if equipped).
4. Loosen drain plugs and drain fuel into a suitable container.
NOTE: Lifting up on retaining ring as it is rotated helps to get it past raised
locators.
5. Firmly grasp the retaining ring and rotate it counterclockwise ¼ turn. Remove
ring with filter element.
6. Inspect filter mounting base for cleanliness. Clean as required.
NOTE: Raised locators on fuel filter canisters must be indexed properly with
slots in mounting base for correct installation.
7. Install new filter elements onto mounting bases. Be sure elements are properly
indexed and firmly seated on bases. It may be necessary to rotate filters for
correct alignment.
If equipped with water separator bowl (E), remove filter element from separator bowl.
Drain and clean separator bowl. Dry with compressed air. Install bowl onto new
element. Tighten securely.
8. Align keys on filter element with slots in filter base.
