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. |
Note: Apply Tooling (M) to all bores when you connect the frames. Lubricate all pin bores, all seals, and all pins with clean grease before installation.
- Position lower cap (55) on the upper frame. Hold the lower cap in place with bolts (53). Make sure that the lower cap is seated firmly against the upper frame.
