Safety

Illustration 1	g02139237

Most accidents that involve product operation, maintenance, and repair are caused by failure to observe basic safety rules or precautions. An accident can often be avoided by recognizing potentially hazardous situations before an accident occurs. A person must be alert to potential hazards. This person should also have the necessary training, skills, and tools to perform these functions properly.

This bulletin may contain hazardous steps. A safety alert symbol like the one below is used to call attention to a hazard.

Warning messages identify a specific, imminent, latent, hazard that has a reasonable probability of resulting in personal injury or death if the warning is ignored.

Show/hide table

Do not attempt to disassemble or assemble this machine until you read and understand the disassembly and assembly instructions. Improper disassembly and assembly procedures could result in injury or death.

Show/hide table

Inspect all threaded components before use. Damaged threads may fail under hydraulic pressure. Broken threads may release flying objects that are propelled with great force. Personal injury or death can occur if struck by flying objects.

Show/hide table

Do not stand near the hydraulic press while the press is in operation. A component that slips or breaks under pressure may fly into the air with great force. Personal injury or death can occur if struck by flying objects.

Canceled Part Numbers and Replaced Part Numbers

This document may not include all canceled part numbers and replaced part numbers. Use NPR on SIS for information about canceled part numbers and replaced part numbers. NPR will provide the current part numbers for replaced parts.

22. If the roller contains a threaded plug, a compression fitting must be used to perform a pressure test on the assembled roller.

23. Use the 170-5664 Test and Fill Cart Gp to evaluate and fill the joint.

24. Apply 9S-3263 Thread Lock Compound to the pipe plug and install the plug into the oil cavity of the roller.

    Note: The correct torque for 3D-4603 Pipe Plug is 10 N·m (7.5 lb ft). The correct torque for 9W-2146 Pipe Plug is 25 N·m (18.0 lb ft).

25. If 170-5664 Test and Fill Cart Gp is not available, use FT-2724 Pressure Gauge Tool Gp to perform a pressure test on the roller. Refer to Undercarriage Reconditioning Bulletin, SEBF8594, "Nitrogen Pressure Test Unit (FT-2724)".

    1. Introduce nitrogen into the oil cavity to a pressure of 138 kPa (20.0 psi).

    2. Turn the ball valve to the shutoff position.

    3. Close the pressure gauge.

    4. Observe the pressure for 10 seconds. A pressure drop of 3.4 kPa (0.50 psi) or less is acceptable.

    5. Add the correct quantity of 8T-9548 Oil to the roller. Refer to Table 7 or Undercarriage Reconditioning Bulletin, SEBF8574, "Track Roller Oil Fill Volume" for the oil volumes.
