TANK GP-FUEL 2801060 - Caterpillar

Removal Procedure
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 Tools and Shop Products Guide" for tools and supplies suitable to collect and contain fluids on Caterpillar products.Dispose of all fluids according to local regulations and mandates.
Personal injury can result from hot oil or hot components.At operating temperature, oil is hot and under pressure. Hot oil can cause burns.Remove the fill cap only when the engine is stopped, and the fill cap is cool enough to touch with your bare hand.Do not allow hot oil or components to contact skin.
Personal injury can result from the sudden release of high pressure oil.Be sure the engine has been shut off for a minimum of five minutes to ensure that the accumulator pressure is zero.The accumulator is filled with dry nitrogen. Do not loosen or remove the valve or the cap from the top of the accumulator.
Release the pressure in the hydraulic system. Refer to Disassembly and Assembly, "Machine Preparation for Disassembly and Assembly".

Note: For easier installation, place identification marks on all hose assemblies, on all wire harnesses, and on all tubes. Plug and cap all hose assemblies and tubes in order to prevent fluid loss and system contamination.
Disconnect wire harness (3) from the blade cushion accumulators. Disconnect wire harness (5) from the blade cushion accumulators.
Disconnect hose assembly (4) and disconnect hose assembly (6) from the blade cushion accumulators.

Note: Cleanliness is an important factor. Before the assembly procedure, the exterior of the component should be thoroughly cleaned. This will help to prevent system contamination.
Place the two blade cushion accumulators in position on the frame of the machine. Install two bolts (1), two washers, and two clamps that hold the blade cushion accumulators.
Install two washers and install two bolts (2) that hold the accumulator valves to the frame of the machine.
Install hose assembly (4) and install hose assembly (6) to the original positions on the blade cushion accumulators.
Connect wire harness (3) and connect wire harness (5) to the original locations.
Dry nitrogen is the only gas approved for use in the accumulator. Charging the accumulator with oxygen gas will cause an explosion. This danger will not happen if nitrogen cylinders with standard CGA (Compressed Gas Association, Inc.) Number 580 connections are used. When you order nitrogen gas, be sure that the cylinders are equipped with CGA No. 580 Connections. Do not use color codes or other methods of identification to tell the difference between nitrogen and oxygen cylinders.
Check the charge pressure of the blade cushion accumulators. If necessary, charge the blade
