ReferenceOperation and Maintenance Manual, SEBU8284, "Work Tool Installation and Removal"Note: The crosshead assembly must be installed with the pin retention bolt on the left side of the stick when viewed from the cab.
Personal injury or death can result from escaping fluid under pressure.Escaping fluid under pressure, even a very small pin-hole size leak, can penetrate body tissue and cause serious injury and possible death. If fluid is injected into your skin, it must be treated immediately by a doctor familiar with this type of injury.Always use a board or cardboard when checking for a leak.
Check valves in the hydraulic system may allow pressure to exist in the hydraulic lines after the engine has been stopped. Pressure must be relieved prior to servicing the components of the hydraulic system. Failure to relieve pressure prior to servicing may result in personal injury.
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 operating any compartment or disassembling any component containing fluids.After collecting all fluids in suitable containers, dispose of all fluids according to local regulations and mandates.
Note: Ensure that the work tool is compatible with the host machine. Consult any Caterpillar dealer for information on matching the work tool to the host machine.
Clean the pin. Grease the pin.
