Section 110-0030
Fuel Filter/Water Separator - Drain the water and
sediment from the separator daily. Position the
vehicle on a level work area, apply the parking brake,
shut off the engine and, with a suitable container
below the drain valve to catch spillage, open the drain
valve by hand. Turn the valve anticlockwise
approximately 1.5 - 2 turns until draining occurs.
Drain the filter sump until clear fuel is visible. Turn
the valve clockwise approximately 1.5 - 2 turns to
close the drain valve.
Note: Do not overtighten the drain valve as
overtightening can damage the threads.
Every 250 Hours or 6 Months
Fuel Filters (2) - Clean the area around the fuel filter
head and replace the fuel filters.
Note: There is a fuel system shut off valve at the
filter head. Closing this valve will prevent loss of fuel
prime at time of filter replacement.
Position the vehicle on a level work area, apply the
parking brake and switch off the engine. Close fuel
system shut off valve and, using strap type filter
wrench, remove and discard fuel filters (2).
Apply a thin film of clean engine oil to the gasket
surface of new fuel filters (2) and fill fuel filters (2)
with clean fuel specified in Section 300-0020,
LUBRICATION SYSTEM.
Install new fuel filters (2) on the filter head and
tighten by hand until the gasket contacts the filter
head surface. Tighten fuel filters (2) per the filter
manufacturer's instructions.
Note: Mechanical tightening of the filters is not
recommended, and may result in seal and/or
cartridge damage. Tighten filters by hand only.
Open the shut off valve, start the engine and check
for leaks. If leaks are noted, have them corrected.
Engine Oil and Oil Filter (3) - Replace the
lubricating oil and oil filter.
WARNING
Avoid direct contact of hot oil with your skin.
Hot oil can cause serious personal injury.
Operate the engine until the water temperature
reaches 60° C (140° F). Shut off the engine. Position
a suitable container under the engine oil drain plug
and drain the oil immediately to make sure all the oil
and suspended contaminants are removed from the
engine.
Position the vehicle on a level work area, apply the
parking brake and switch off the engine. Using strap
type filter wrench, remove lube oil bypass filter and
full flow lube oil filter (3). Discard the filters if they
are not required for a failure analysis.
Note: Cut all the way around the top of lube oil filter
(3) using a pipe cutter or hacksaw. Inspect the
pleated paper element for debris. Metal debris in the
filter can reveal impending engine failure. If debris is
found, find the reason for the debris and make the
necessary repairs.
Clean the area around the oil filter head and gasket
sealing surface of the filter head.
Note: The 'O' ring can stick on the filter head. Make
sure the 'O' ring is removed and discarded.
Note: Fill the filter with clean lubricating oil prior to
installation. The lack of lubrication during the delay
until the filter is pumped full of oil is harmful to the
engine.
Apply a thin film of clean lubricating oil to the gasket
surface of the new filter and fill the filter with clean
lubricating oil specified in Section 300-0020,
LUBRICATION SYSTEM.
Install the filter on the filter head as specified by the
filter manufacturer. The tightening instructions are
normally printed on the outside of the filter.
Note: Mechanical tightening of the filter is not
recommended, and may result in seal and/or
cartridge damage. Tighten filter by hand only.
Check and clean the engine oil drain plug threads and
the seal surface. Install and tighten the drain plug to a
torque of 100 Nm (75 lbf ft). Fill the engine with clean
lubricating oil specified in Section 300-0020,
LUBRICATION SYSTEM. The oil level should be
between the low (L) and high (H) marks on the
dipstick.
