Install bolts (3) in order to secure pump (1) to pump (2) .Note: The correct priming and break-in procedures should always be used, when the parts of the rotating group have been rebuilt or replaced. The break-in procedure is important because improper break-in will result in failures after minimal hours of the pumps and of the motors. Improper break-in procedures leave little evidence about the failure. Prime a rebuilt pump or a rebuilt motor.Note: Abrasive particles must be removed from the hydraulic system. Contamination is a frequent cause of pump failures. Pump failures are often due to improper flushing techniques from a previous failure.Note: Hydraulic system repair is required if the components have been run to catastrophic failure. The amount of hydraulic system repair will depend on the extent of metal contamination. Do not use the kidney loop filtering method as the only clean-up procedure. Refer to Special Instruction, SMHS6866 for loaders. Refer to Special Instruction, SMHS6936 for excavators. These procedures can be adapted to the hydraulic systems on other Caterpillar machines. The basic flushing procedures are similar. Be sure to flush the system thoroughly after a failure. Use Tooling (P) to assist flushing the hydraulic system. Refer to Tool Operating Manual, NEHS0643 for information on Tooling (P) .Note: Once all contaminants have been thoroughly flushed from the system, a baseline SOS analysis must be completed. Refer to Special Instruction, SEBF3116 for information on oil sampling. The SOS oil sample is used to
