FUEL SYSTEM
Change the fuel filters as listed in the SCHEDULED MAINTENANCE GUIDE or sooner if a power
loss is evident. If a power loss persists, find the cause and correct. Fuel containing more than the
average impurities may require changing filters at shorter intervals.
The fuel filters are located as shown in Fig. 5.40.
Be careful not to allow dirt, water or other foreign material to get in a new filter. Keep new filters in
the original package until ready for installation.
NOTE: Use only genuine filters because of possibility of damage of the fuel system.
REPLACEMENT
Fig. 5.40. Fuel Filters
1. Open the engine side access cover on the right side of the machine.
2. Clean the area around the fuel filters.
3. Using a filter wrench, remove the fuel filters by turning them counterclockwise. Discard the
filters in a suitable manner if they are not needed for any reason.
4. Clean the fitter gasket surfaces of the filter header for each filter (Fig. 5.40). Replace the filter O-
rings.
Fig. 5.41. Cleaning Fuel Filter Header Fig. 5.42. Preparing Filters For Installation
5. Fill the new filters with clean diesel fuel. Then apply a thin coat of clean engine oil to the seal of
the filter. See Fig. 5.42.
6. Install the filters on the filter header until the filter seal contacts the seal surface on the filter
header and then turn the filter an additional 1/2 to 3/4 turn by hand (Fig. 5.43). Do not overtighten
the filter or damage may result to the filter seal or threads. Use genuine filters only.
