FAQ

Q: Is this connecting rod screw a direct replacement for the OEM Caterpillar part?

A: Yes. This screw is manufactured to the exact OEM specifications (8-98023-526-0). It is a direct drop-in replacement for the original Caterpillar C6.6 connecting rod bolt. No modifications are required for installation.

Q: What is the recommended torque specification for this bolt?

A: For the C6.6 engine, the standard torque specification for the connecting rod screw is typically 45 Nm (33 lb-ft) + 90 degrees. However, we strongly recommend consulting the official Caterpillar service manual for your specific engine serial number, as torque values can vary slightly. Always use a calibrated torque wrench and follow the stretch-to-yield procedure if specified.

Q: Should I replace the connecting rod bolts when rebuilding a C6.6 engine?

A: Yes. Connecting rod bolts are “torque-to-yield” (TTY) fasteners. Once torqued to specification, they stretch and should never be reused. For a reliable engine rebuild, we recommend always installing new connecting rod screws to ensure proper clamping force and prevent rod failure. This screw is designed for single-use only.
