Product Title

1-12235036-3 / 1-12239005-1 Isuzu 6WG1 Engine Connecting Rod Bolt and Nut Set

Product Overview

This product is a dedicated connecting rod bolt and nut set for the Isuzu 6WG1 series diesel engine, comprising two part numbers: 1-12235036-3 (connecting rod bolt) and 1-12239005-1 (connecting rod nut). The connecting rod bolts and nuts are among the most critical fasteners in an engine, securing the connecting rod cap firmly to the connecting rod body while withstanding extremely high alternating loads and impact forces. Manufactured from high-strength alloy steel with precision heat treatment and surface finishing processes, this set ensures reliability and durability under the most demanding conditions. It is widely used in construction machinery and generator sets powered by the 6WG1 engine.

Product Features

• OEM Specification – Manufactured to strict Isuzu OE standards for direct replacement without any modification.

• High-Strength Material – Made of premium chrome-molybdenum alloy steel with excellent tensile and yield strength, capable of withstanding enormous inertial forces and combustion pressures generated at high engine speeds.

• Precision Thread Rolling – Threads are precision-rolled for tight fit and reliable locking, effectively preventing loosening due to vibration.

• Complete Set – Includes both bolts and nuts as a matching set, ensuring compatibility and consistency while eliminating the hassle of separate sourcing.

• Strict Quality Control – Each batch undergoes hardness testing, tensile testing, and dimensional inspection to ensure compliance with OEM technical standards.

Precautions

• Connecting rod bolts are critical safety components. Installation must be performed by a professional technician using a torque wrench, strictly following the torque and angle specifications in the OEM service manual.

• Thoroughly clean the bolt holes before installation; remove any oil, metal chips, or old thread-locking compound residues.

• Follow the OEM-specified tightening sequence and step-by-step torque application to prevent connecting rod distortion caused by over-tightening a single bolt.

• Apply a small amount of engine oil to the threads during installation to achieve accurate preload.

• Important Note: Connecting rod bolts are subject to fatigue under alternating loads. When performing major overhauls or replacing connecting rods, it is strongly recommended to replace the bolts and nuts as a set; do not reuse old fasteners.
