Description

Piston M-7156-50 (0.50 mm) – Oversize The M-7156-50 Piston Assembly (0.50 mm oversize) is a precision-engineered diesel piston designed for engines that require a 0.50 mm oversize replacement due to cylinder wear, scoring, or machine reboring. This piston restores proper piston-to-liner clearance, strengthens compression, and improves overall combustion efficiency in heavy-duty diesel applications. Constructed from high-strength alloy materials, the M-7156-50 piston is built to withstand extreme heat and high-pressure combustion cycles. The piston features a precision-machined skirt, optimized crown geometry, and accurately machined ring grooves to ensure smooth movement, reduced friction, and long-term durability. This oversize piston is ideal for engine rebuilds, in-frame overhauls, machining corrections, and high-performance diesel repairs. ✔ Key Features & Technical Advantages OEM-spec M-7156-50 0.50 mm oversize piston assembly Designed for cylinders rebored or honed 0.50 mm oversize Restores compression, sealing performance, and fuel efficiency Reduces blow-by, oil consumption, and exhaust smoke High-strength alloy construction for maximum durability Precision machining ensures smooth piston operation & reduced wear Ideal for rebuild shops, machine shops, and fleet maintenance programs
