Removal Procedure for the Travel Motor on CIPI Undercarriage Arrangements which are Based on 330 Track Type Excavators
| Required Tools | |||
|---|---|---|---|
| Tool | Part Number | Part Description | Qty |
| A | 6V-2156 | Link Bracket | 1 |
| 6V-2082 | Lifting Hook | 1 | |
| 1U-7558 | Mounting Adapter Gp | 2 | |
Note: Prior to removing the travel motor, drain the oil from the final drive into a suitable container for storage or disposal. The capacity of the final drive is 13 L (3.4 US gal).
 |
At operating temperature, the hydraulic oil is hot and under pressure. Hot oils can cause burns. To prevent possible personal injury, release the pressure in the implement hydraulic circuit (boom, stick, bucket, and swing), travel circuits, and the hydraulic oil tank at the filler cap before any hydraulic lines or components are disconnected or removed. Remove the filler cap only when the engine is stopped and the filler cap is cool enough to touch. |

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. |
- Release the hydraulic system pressure. Refer to Disassembly and Assembly, "Hydraulic System Pressure - Release" in this manual.
- Remove two covers (1) from the rear of the undercarriage frame assembly.

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: A hydraulic oil sample should be obtained before any maintenance is performed in order to establish the system contaminant level. Refer to Fluid Analysis Laboratory Guide, SEBF3116, "Obtaining an Oil Sample for S·O·S Analysis". Refer to Operation and Maintenance Manual, "Sampling Interval and Location of Sampling Valve" for the correct location.
- Drain the oil from the final drive into a suitable container for storage or disposal. The capacity of the final drive is 10 L (.6 US gal).
