------ WARNING! ------

At operating temperature, the hydraulic tank is hot and under pressure.

Hot oil and components can cause personal injury. Do not allow hot oil or components to contact skin.

Remove the filler cap only when the engine is stopped, and the filler cap is cool enough to touch with your bare hand. Remove the filler cap slowly in order to relieve pressure.

----------------------

------ WARNING! ------

Personal injury or death can result from escaping fluid under pressure.

Escaping fluid under pressure, even a very small pin-hole size leak, can penetrate body tissue and cause serious injury and possible death. If fluid is injected into your skin, it must be treated immediately by a doctor familiar with this type of injury.

Always use a board or cardboard when checking for a leak.

----------------------


NOTICE

Care must be taken to ensure that fluids are contained during performance of inspection, maintenance, testing, adjusting and repair of the product. Be prepared to collect the fluid with suitable containers before opening any compartment or disassembling any component containing fluids.

Refer to Special Publication, NENG2500, "Caterpillar Dealer Service Tool Catalog" for tools and supplies suitable to collect and contain fluids on Caterpillar products.

Dispose of all fluids according to local regulations and mandates.



NOTICE

To prevent dirt and contaminants from entering the hydraulic system, always plug or cap the lines, fittings, or hoses as they are disconnected.

This action also lessens the chance of oil spills.


General Information

Introduction

The 295-0048 Bulk Fuel Filtration System is an integrated unit designed to remove particulates and water from diesel fuel. The maximum rated flow for this system is 1136 L/min (300.1 US gpm).




Illustration 3g02727457

The system consists of one particulate pre-filter vessel, one fuel/water separator vessel, and a slug/differential control valve mounted on a base/drip pan assembly. Inlet and outlet butterfly valves are included. All pressure containing components are welded carbon steel or ductile iron designed for use in all environments.

Pre-filter elements remove most of the solid particulate contamination. Coalescer elements and separator canisters remove water and filter the fuel. If restriction in the system (clogged filter elements or high water level) exceeds 172 kPa (25.0 psi), the slug control valve will close, stopping fuel flow.

Filters should be replaced and separator canisters cleaned every 6 months, or whenever differential pressure reaches 138 kPa (20.0 psi).

The slug valve also limits flow through the system to 1136 L/min (300.1 US gpm) maximum.

The system is equipped with a pressure relief valve located on the coalescer vessel cover. The pressure relief valve prevents the system from being pressurized above 1034 kPa (150.0 psi).

Applications

The Caterpillar Bulk Fuel Filtration System is intended for use in any application where users store fuel for machines or engines. The filter unit is installed in series between the fuel pump on the fuel storage tank and the fuel station, or fuel transport vehicle.

Note: The system does not require electrical power unless it is used in cold climates. Optional 307-0655 Electric Heater (120 V) or 307-2569 Electric Heater (220 V) are available for cold climates where water removed from the fuel may freeze.

Start up After Maintenance

Perform the Start-up Procedure after replacing filter elements, or any other maintenance where the bulk fuel filtration system is opened.

For step by step information, refer to ""Start-up Procedure" " in the ""Operation Section" " of this manual.

Slug Valve Reset

Differential fluid pressure above 172 kPa (25.0 psi), caused by filter element restrictions, will result in the slug valve closing, stopping all fuel flow through the bulk fuel filtration system. Before refueling can resume, do the following:

  1. Turn OFF the fuel delivery pump.

  1. CLOSE inlet and outlet butterfly valves.

Note: If slug valve (18) will not reset, or immediately closes again, refer to the ""Troubleshooting" " Section in this manual, or contact your local Cat dealer for assistance.


NOTICE

Slug valve is factory set to 172 kPa (25.0 psi) differential pressure. Do NOT adjust factory setting. Changing the setting can result in improper fuel filtration and damage to bulk fuel filtration system components.


Note: To ensure fuel quality, have fuel cleanliness tested on a regular basis. For more information on fuel quality testing, refer to the latest version of Special Instruction, SEBU6250, "Caterpillar Machine Fluid Recommendations".

Troubleshooting

Table 4
Troubleshooting Chart    
Problem     Possible Cause     Possible Solution    
No fuel flow.     Inlet or outlet valve is closed.     Completely open inlet/outlet valve.    
Fuel hose is kinked. Straighten hose and/or provide larger hose.    
Automatic slug valve shutdown. Check differential pressure gauge follower needles for differential pressure reading greater than
172 kPa (25.0 psi). The slug valve will close if filters are restricted. Change filter elements and reset slug valve.    
Check sight glass for high water accumulation. Wait until system purges water or drain water manually. Reset slug valve.
Differential gauge reading greater than
69 kPa (10.0 psi) at start-up.    
Air in the system.     Open vent valve at top of pre-filter vessels to release trapped air.    
Differential gauge reading greater than
172 kPa (25.0 psi).    
Filter elements are restricted.     Replace filter elements and clean vessels. Reset slug valve, if necessary.    

Maintenance Record

Replace filters at least every 6 months. Clean debris from vessels annually, or as needed to maintain cleanliness.
