VANE ASSEM. 2J8265 - Caterpillar

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.
Lubricants
Approved hydraulic oil must be used to obtain the 4000 hour hydraulic oil change. Refer to the list that follows for approved oils.Caterpillar Hydraulic Oils

TDTO (TMS)
DEO SYN
Cat Arctic DEO SYN
Cat Arctic TDTO SYN
Cat ECF-1-a, ECF-2, ECF-3
MTO
Cat TO-4
Cat BF-1Commercial Oils
Commercial oils with a minimum zinc content of 900 ppm that meet Cat ECF-1, ECF-2, ECF-3, or the Cat TO-4 specification can be used. Also, acceptable commercial oils must have an SAE viscosity grade of one of the following SAE specs.
SAE10W
SAE0W20
SAE0W30Note: Industrial hydraulic oils are not recommended for the hydraulic systems of Caterpillar machines. Industrial hydraulic oils are more likely to allow corrosion and industrial hydraulic oils are more likely to allow excessive wear.Change the Hydraulic Oil
Operate the machine in order to warm the oil.Park the machine on level ground. Lower the bulldozer blade to the ground and apply slight downward pressure. Engage the parking brake and stop the engine.

Remove the hydraulic tank filler cap slowly in order to relieve any pressure.
Wash the filler strainer and the filler cap in a clean nonflammable solvent.
Remove the oil drain plug. The oil drain plug is located under the right rear of the machine.
Attach a hose to a 1 inch NPT pipe nipple. This 1 inch NPT pipe nipple should have a length of 100 mm (4 inch).
Install the pipe nipple into the drain plug opening.
Rotate the pipe nipple clockwise in order to open the internal drain valve. Allow the oil to drain into a suitable container.
Remove the pipe nipple. The valve for the hydraulic tank will close.
Clean the drain plug and install the drain plug. Tighten the drain plug to a torque of 68 7 N m (50 5 lb ft).
See Operation and Maintenance Manual, "Hydraulic System Oil Filter - Replace". Change the hydraulic system filter.
Install the filler strainer.
See Operation and Maintenance Manual, "Capacities (Refill)" in order to determine the amount of hydraulic oil that is needed to fill the hydraulic oil tank. Fill the hydraulic oil tank with the appropriate oil.
Inspect the filler cap gasket. Replace the gasket if damage or wear is evident.
Install the filler cap.
Start the engine. Run the engine for a few minutes.

Maintain the oil level to the "FULL" mark in the sight gauge. Add oil, if necessary.
Stop the engine.ReferenceSee Special Publication, SEBU6250, "Caterpillar Machine Fluid Recommendations", "Sampling Interval Schedule and Location of Sampling Valve", Special Publication, SEBU6250, "Caterpillar Machine Fluid Recommendations", "S O S Oil Analysis", and Special Publication, SEBU6250, "Caterpillar Machine Fluid Recommendations", "Lubricant Viscosities"for additional information.
