Product Overview
This high-quality 6BD1 Engine Piston Liner Set (Part Number 1-12111428-0) is a direct replacement component designed for the robust Isuzu 6BD1 and 6BD1T diesel engine family. Specifically engineered for the 5.2L (317 CID) displacement, this piston liner set is a critical component for restoring compression, reducing oil consumption, and eliminating blow-by in medium-duty diesel engines.
Commonly used in Isuzu medium-duty trucks and heavy equipment applications, including excavators, this genuine-specification set ensures a precise fit for the 6BD1 engine platform. Whether you are performing a complete engine overhaul or repairing a specific cylinder, this 115mm diameter piston and liner set provides the reliability needed for demanding industrial and commercial operations. Please verify your engine model (4BD1 or 6BD1) and year range (2005-2006) to confirm application fitment.

FAQ
Q1: How do I confirm if this 1-12111428-0 piston liner set fits my engine? A: First, locate the engine model plate on your equipment. It should state “6BD1”, “6BD1T”, or “4BD1”. Second, check the piston diameter. This set is for a standard 115mm bore. If your engine has been previously rebored to an oversize, this standard set will not fit. Finally, verify the OEM part number on your current piston (1-12111428-0). If all three match, this set is correct.
Q2: What is included in this “piston liner set”? Does it include piston rings and pins? A: This specific set includes the piston and the cylinder liner (sleeve). It does not typically include piston rings, wrist pins, or circlips. We recommend purchasing a separate ring set (specified for the 6BD1 115mm bore) and pin kit to complete your engine rebuild. Please check the product listing details or contact us for a bundled kit if needed.
Q3: Can I install this piston liner set without special tools? A: While experienced mechanics can install liners using a press or driver, we strongly recommend using a proper cylinder liner puller and installer tool to prevent damaging the new liner or the engine block. The piston should be installed using a ring compressor. If you are not experienced with diesel engine rebuilding, we advise seeking professional installation to avoid costly mistakes. We offer video technical support after the sale to guide you through the process.
