Start By:
- Release the pressure in the hydraulic system. Refer to Disassembly and Assembly, "Hydraulic System Pressure - Release".
- Remove the gear pump. Refer to Disassembly and Assembly, RENR4838, "Gear Pump - Remove".
- Remove the tire and rim. Refer to Disassembly and Assembly, "Tire and Rim - Remove and Install".

Personal injury can result from hydraulic oil pressure and hot oil. Hydraulic oil pressure can remain in the hydraulic system after the engine has been stopped. Serious injury can be caused if this pressure is not released before any service is done on the hydraulic system. Make sure all of the work tools have been lowered to the ground, and the oil is cool before removing any components or lines. Remove the oil filler cap only when the engine is stopped, and the filler cap is cool enough to touch with your bare hand. |
 |
|
Personal injury or death can result without releasing all of the hydraulic pressure. Release all the pressure from the hydraulic system before any lines are disconnected. |

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, "AVSpare Tools and Shop Products Guide" for tools and supplies suitable to collect and contain fluids on AVSpare products. Dispose of all fluids according to local regulations and mandates. |
| NOTICE |
|---|
Keep all parts clean from contaminants. Contamination of the hydraulic system with foreign material will reduce the service life of the hydraulic system components. To prevent contaminants from entering the hydraulic system, always plug or cap the lines, fittings, or hoses as they are disconnected. Cover any disassembled components and clean them properly before assembly. Clean the hydraulic system properly after any major component exchange or especially after a component failure, to remove any contamination. |
Note: Put identification marks on all hoses, on all hose assemblies, on all wires, and on all tube assemblies for installation purposes. Plug all hose assemblies and all tube assemblies. This helps to prevent fluid loss, and this helps to keep contaminants from entering the system.
Note: Cleanliness is an important factor. Before you begin the disassembly procedure, the exterior of the components should be thoroughly cleaned. This will help to prevent dirt from entering the internal mechanism. Precision components can be damaged by contaminants or by dirt. Perform disassembly procedures on a clean work surface. Keep components covered and protected at all times.
- Drain the hydraulic tank. Refer to Operation and Maintenance Manual, SEBU7468, "Hydraulic System Oil - Change".
- Remove plug (1). Drain the drive chain oil into a suitable container. Apply Tooling (A) to plug (1). Apply Tooling (B) to plug (1). Install plug (1) .
