Genuine Nissan Bolt Conrod Big End ZD30CR TD42 TD42T TD42Ti - Nissan Patrol Y61 GU 1997-2017

This is a replacement connecting rod big end bolt, a critical engine component for Nissan's TD42, TD42T, TD42Ti, and ZD30 diesel engines. Located deep inside the engine, these high-stress fasteners are responsible for securing the connecting rod and its bearing to the crankshaft, enduring immense forces with every single rotation of the engine.

Connecting rod bolts are single-use, torque-to-yield (TTY) fasteners. This means they are engineered to permanently stretch when torqued to the correct specification during assembly. They must be replaced every time they are removed for an engine rebuild or bearing service. Reusing old bolts or using inferior, low-quality replacements is a major risk, as a failed bolt will cause immediate and catastrophic engine failure, often resulting in a destroyed engine block, crankshaft, and pistons.

Product Features

• Direct-Fit Replacement: A direct-fit, high-quality replacement for the original equipment (OEM) big end bolt, ensuring correct installation and performance.
• Torque-to-Yield Design: Engineered as a single-use stretch bolt that must be replaced once undone to ensure proper clamping force.
• High-Strength Construction: Manufactured from high-tensile steel to withstand extreme internal engine forces and prevent stretching or failure under load.
• Required Additional Parts: When replacing conrod bolts, you will also need new connecting rod bearings. A full engine rebuild typically also requires a gasket kit, main bearings, piston rings, and fresh fluids.
