ACTION REQUIRED
Show/hide table
| Update brake charging system as per M0117303, Special Instruction, "Procedure to Update Brake System on Certain 793F Off-Highway Trucks". The updated system will increase the accumulator capacity for the service brakes and reduce the duty cycle of the charge pump. When the pump is replaced, care must be taken to ensure the pump is properly primed and started up slowly so as to avoid any start-up damage. |
