the fuel tank. When this has been completed,
the pump head must be screwed back into
the filter/separator assembly.
Start the engine and visually check the fuel
system for leaks.
Governor Control Seals
As the governor is precisely adjusted, most
of the controls are sealed, please do not
break them. Should any adjustment be
necessary, contact your local Ingersoll-Rand
branch or distributor.
Note: Ingersoll-Rand will not accept any
warranty claim on an engine with broken
governor seals.
Replacing Fuel Filters
Replace the fuel filter at specified intervals
before it is clogged with dust to adversely
affect the fuel flow. Also, replace the fuel filter
after the engine has fully been cooled.
1) Remove the fuel filter using a filter wrench
(customer procured). When removing the
fuel filter, hold the bottom of the fuel filter with
a piece of rag to prevent the fuel oil from
dropping. Wipe up any fuel spillage.
2) Clean the filter mounting surface and
slightly apply fuel oil to the gasket of the new
fuel filter.
3) Install the new filter, manually turning until
it comes into contact with the mounting
surface, and tighten it further to 1/2 at a turn,
using a filter wrench.
Tightening torque:
11.8 ~15.6N•m (1.2~1.6kgf•m)
Applicable Fuel Filter Part No. 22226369.
4) Bleed the fuel system. Refer to Inspection
at 50 hours.
IMPORTANT: Use genuine IR part (super
fine mesh filter). Otherwise, it will result in
engine damage, uneven engine performance
and shorter engine life.
Changing Oil/Water Separator
Element
Note: the cartridge and bowl contain fuel.
Take care not to spill it during disassembly
and reassembly.
The fuel filter/separator also provides
primary filtration and the element “C” should
be changed every 500 operating hours or 6
months, whichever comes first.
Change Procedure:
• Unscrew the element “C” from the
head taking care not to spill fuel
inside the machine. Drain any fuel
within into a suitable container, then
unscrew the clear bowl “D” from the
element.
• Discard the old element.
• Remove the old “O” ring from the
bowl “D” and install the new one
supplied with the element. Apply a
light coat of clean engine oil to the
“O” ring and screw the bowl “D”
onto the new element “C”.
• Using a clean cloth, wipe the
sealing face of the filter/separator
head to ensure correct seating of
the sealing ring.
• Fill the element/bowl assembly with
clean fuel oil then apply a light coat
of clean engine oil to the new
element seal ring.
• Screw the new element onto the
head firmly by hand.
• Follow the “fuel system air
bleeding” procedure.
