Connecting Rod Assembly 1-12230185-0 1122301850 for ISUZU CXZ CYZ EXZ CXZ51K 6WF1 — IZUMI Quality OEM Spec
The Connecting Rod Assembly with OEM numbers 1-12230185-0 / 1122301850 (alternate 1-12230185-1 / 1-12230185-Y / 8981159480) is a verified direct-fit replacement for ISUZU 6WF1 series diesel engines. This connecting rod is a critical component of the engine's crank-connecting rod mechanism, responsible for transmitting the piston's reciprocating motion to the crankshaft. It is widely used in ISUZU CXZ, CYZ, EXZ, CXZ51K series heavy trucks and Hitachi ZX450, ZX470, ZX850 large excavators.
The connecting rod connects the piston to the crankshaft, transmitting combustion pressure from the piston to the crankshaft to drive rotation and output power. The connecting rod is subjected to alternating tensile and compressive loads, bending loads, and inertial forces, experiencing repeated compression, tension, and shear forces during each engine cycle. This product is made from forged steel, precision-machined and surface-treated to maintain structural integrity and dimensional stability under high-speed, high-load conditions.
- Engine Knocking Noise — Heavy "thumping" or rhythmic metallic knocking during operation (worn rod bearings or bent rod)
- Low Oil Pressure — Oil pressure warning light illuminates (excessive rod bearing clearance causing oil leakage)
- Severe Engine Vibration — Intense vibration during operation (bent rod or weight inconsistency causing imbalance)
- Significant Power Loss — Poor acceleration; insufficient power (rod deformation affecting compression ratio and combustion efficiency)
- Connecting Rod Fracture — Complete engine destruction in severe cases (fatigue fracture or overload)

- The connecting rod is a critical load-bearing component of the engine crank-rod mechanism — failure leads to severe engine damage or catastrophic destruction
- Rod bearings and rod bolts must be replaced simultaneously when replacing the rod (must use new bolts)
- Must be installed with correct torque and angle as specified in the workshop manual
- Recommended to replace as a complete set (all rods in the same engine) for weight consistency and balance
- For 100% accurate fitment, please provide VIN (Chassis Number) or engine model
