Introduction
Do not perform any procedure that is outlined in the Special Instruction until the entire instruction has been read and understood.Check Valve Torque
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, "Dealer Service Tool Catalog" for tools and supplies suitable to collect and contain fluids on Cat products.Dispose of all fluids according to local regulations and mandates.
The check valves that are located within the fuel pressure regulator group are sensitive to assembly torque. In order to eliminate the risk of valve distortion, torque the check valves to 28 3 N m (21 2 lb ft). Refer to Table 1 for the check valve part numbers that required the torque that is listed above.
