FAQ

Q1: Will this rocker arm assembly fit my Nissan TD27 engine from a 1995 excavator?
A: This assembly is designed for the Nissan TD27 diesel engine family, which was widely used from the late 1980s through the 2000s. However, we recommend verifying by comparing your old part number with our OEM cross-reference (13257-43G03, 13257-43G00). If your part number matches, it will be a direct fit. If not, measure the rocker shaft diameter and arm length to confirm compatibility.

Q2: Does this assembly include the rocker shaft and mounting bolts?
A: Yes, this is a complete rocker arm assembly. It typically includes the rocker arms, rocker shaft, support brackets, adjusting screws, lock nuts, and mounting hardware. You should not need to purchase additional components for the installation. We recommend replacing all valve train components (pushrods, lifters) simultaneously for optimal performance.

Q3: What is the recommended valve lash adjustment after installing this assembly?
A: For the Nissan TD27 engine, the standard cold valve clearance is typically: Intake: 0.25mm (0.010 in) and Exhaust: 0.30mm (0.012 in). However, always consult your specific engine service manual for the exact specification, as turbocharged variants may differ. After installation, run the engine to operating temperature, allow it to cool, and re-check the clearance for accuracy.
