- Installation must use original factory specifications for main bearing shells, connecting rod shells, thrust washers, and oil seals; tighten the main bearing caps and connecting rod bolts in stages according to the manufacturer’s required torque.
- It is recommended that this be performed by a technician with heavy-duty diesel engine overhaul qualifications. Cold break-in and oil pressure testing are required after installation.
- When purchasing, verify the engine serial number and crankshaft casting number to avoid incompatibility due to version differences.
