FAQ

Q1: Is this connecting rod sold individually or as a full set for the engine?
A: Typically, connecting rods are sold individually to replace a single failed unit. However, for a complete engine overhaul, a full set matching the number of cylinders (e.g., 4 for a 4-cylinder engine) is recommended to ensure uniform weight and balance. Please specify your quantity requirements when ordering.

Q2: Do I need to replace the connecting rod bolts when installing this part?
A: Yes, it is critically important. Connecting rod bolts are torque-to-yield (TTY) or precision fasteners designed for one-time use. Reusing old bolts can lead to catastrophic engine failure due to stretching or fatigue. Always use new, manufacturer-specified bolts and follow the exact torque and tightening procedure.

Q3: Can this part be used in both industrial and marine applications of the 4TNV84 engine?
A: Yes, the core engine component is generally the same across different applications (industrial, generator, marine). The primary part number (729402-23100 / 129150-23010) identifies the specific connecting rod for the 4TNV84/4TNE84 engine block. Always confirm the engine model number stamped on your engine to ensure correct compatibility.
