Installation Procedure - To suit CAT 16H Grader
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.
Apply hydraulic thread sealant (Loctite
®
222 or similar) to the valve adaptor and fit it to the thread where the
fuel receiver was removed from and tighten.
If using a Wiggins
®
receiver, remove the Circlip from the back of the existing fuel receiver. Take care as the
spring will be under pressure. Remove the spring from the receiver and fit the replacement spring provided,
compress the spring in the receiver and refit the Circlip. Failure to change the springs may result in poor
performance of the system.
Place the O-ring on the black valve, fit the valve to the adaptor and tighten.
Weld the 2”NPT half socket to the far end manhole of the fuel tank.
A large range of NPT and BSP adaptors are available for the purpose of configuration.
Apply hydraulic thread sealant, like Loctite
®
545, etc., to the threads of the vertical float, screw the float into the
fuel tank where the 2” socket was removed from and tighten by Hydrau-Flo
®
tools.
Run the hose to the fuel receiver & keep away from areas of excessive heat and should be clear of rotating or
reciprocating parts. The hose should be secured at intervals of no more than 450mm/18”.
Remove all tags and reenergise all isolated valves and switches.
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.
