Description
Product Overview
The Bonbo Engine Piston Liner 3376015 is engineered to meet the demanding standards of heavy‑duty diesel applications. Constructed from premium carbon steel, the liner offers a robust foundation that resists wear, deformation, and corrosion even under high‑temperature combustion cycles. The machined exterior surface is finished with a sleek black coating that not only enhances aesthetic appeal but also provides an additional barrier against abrasive particles and moisture, extending service life in harsh operating environments.
Designed as a direct replacement for OEM part numbers PT‑6400‑C, 3376015, and M50010‑B, this piston liner integrates seamlessly into a variety of engine families, including Mack, Detroit, International, and CAT models ranging from the 3176 to the 530 series. The part dimensions accommodate wet liners with bore sizes from 3‑7/8″ to 6‑1/4″ and a minimum wall thickness of 0.148 inches, supporting depths up to 15 inches. This broad compatibility eliminates the need for multiple inventory items, simplifying maintenance logistics for fleet operators and service shops.
Beyond its mechanical attributes, the liner’s design emphasizes ease of installation. The precise machining tolerances ensure a snug fit that reduces the risk of misalignment during assembly. The black coating’s low‑friction properties aid in sliding the liner into place, minimizing the effort required by technicians and decreasing the likelihood of damage to surrounding components. This user‑centric approach translates into faster turnaround times and lower labor costs for repair facilities.
Bonbo’s commitment to quality is reflected in the rigorous testing protocols applied to each unit. Every liner undergoes heat‑treatment cycles to achieve optimal hardness, followed by dimensional verification using calibrated metrology equipment. The result is a product that consistently meets or exceeds OEM specifications, delivering reliable performance throughout the engine’s service life. Paired with a 12‑month warranty and a 30‑day satisfaction guarantee, the liner provides peace of mind for purchasers seeking dependable aftermarket solutions.
Usage
This piston liner is ideally suited for heavy‑duty trucks, construction equipment, and agricultural machinery that rely on high‑output diesel engines. Whether the application involves long‑haul transportation, off‑road excavation, or seasonal harvesting, the liner’s durability and heat resistance ensure consistent power delivery and reduced downtime. Technicians will find the product particularly valuable during engine rebuilds, overhauls, or when addressing wear‑related failures in the cylinder bore.
Because the liner is compatible with a wide range of engine series, it serves both original equipment manufacturers and independent service providers. Fleet managers can standardize on a single part number for multiple vehicle models, streamlining parts inventory and reducing procurement complexity. Additionally, the liner’s performance characteristics make it an excellent choice for retrofitting older engines to meet contemporary emissions standards, as the improved wear resistance helps maintain compression efficiency and fuel economy.
