Installation Procedure
– To suit CAT D10R/D11R Dozers
Ensure the working environment is free from hazards or risks before commencing installation.
Follow any on-site safety operating procedures for onsite installation.
Completely drain fuel from fuel tank.
Remove the fuel supply line from the tank adaptor ensuring all residual fuel in the line is caught.
Remove any lower tank adaptors or other fuelling assemblies from the bottom of the fuel tank.
If removing a fast fill system, the lower assembly will likely have an internal pilot line which must be removed in
order to remove this system.
Make sure all threads are free of dirt, grease and excessive fuel.
Install ¼” BSPT nipples into the pilot line port on the blue valve and green float valves using a thread sealer
such as Loctite 242 (blue).
Bolt the HF1103Z0004 tank adaptor to the bottom of the fuel tank using an appropriate thread sealer such as
Loctite 242. Ensure the O-ring on the tank adaptor is in new condition.
Install the blue receiver valve into the HF1103Z0004 adaptor. Use of the 201240 wrench or 101023 sockets is
recommended.
Install the HF1103Z0003 adaptor into the top of the blue valve using an appropriate thread sealing compound.
Use of a strap wrench or other suitable device is recommended.
Reconnect the fuel supply line to the hose adaptor ensuring a fuel-tight connection. Ensure all connection
points are clean and smooth. Use a thread sealer such as Loctite 242 on the bolts.
Remove the existing breather from the top of the fuel tank.
Install the HF1011Z0001 green float adaptor ensuring the mating surfaces are clean and smooth. Ensure the
O-ring on the tank adaptor is in new condition. Use a thread sealer such as Loctite 242 on the bolts.
Install the green float valve using the 200629 wrench or other suitable tool using an appropriate thread sealing
compound. (The exhaust port can be turned independently of the body of the green valve).
Assemble the 3/8” pilot line using either push on hose barbed fittings or other appropriate hose ends. (-6 JIC
fittings are recommended). Determine pilot line length by routing the pilot line in a manner that will provide the
greatest protection from damage.
Support the pilot line using magnetic hose clamps or other suitable connectors ensuri
ng the line isn’t crimped
or twisted.
Refer to the commissioning procedure once installation has taken place.
CAUTION
Make sure to place the O-ring on the black fuel filling valve before
fitting the adaptor and tightening it into place. No O-ring will lead to
fuel leakage.
Incorrect routing of the air venting line such as low point/s or bends
may result in the discharge of fuel condensate via breather vent and
could ignite on a hot surface.
Always have appropriate fire fighting equipment on hand while
undertaking servicing and filling operations.
NOTICE
Refer to the commissioning section of this manual once installation has taken place.
