Description

Piston M-7163-50 (0.50 mm) – Oversize The M-7163-50 Piston Assembly (0.50 mm oversize) is a precision-engineered diesel engine piston designed for engines requiring an oversize piston due to cylinder wear, honing, or machining. This oversize piston restores correct piston-to-liner clearance, improves compression, and ensures optimal sealing and smooth engine operation—even in demanding heavy-duty environments. Manufactured from high-strength alloy materials and engineered to meet strict OEM-grade tolerances, the M-7163-50 piston offers excellent heat resistance, reduced friction, and superior durability. It is specifically designed to correct issues such as low compression, cylinder scoring, blow-by, oil consumption, and loss of power caused by worn or damaged standard-size pistons. Ideal for professional rebuild shops, diesel technicians, and fleet maintenance operations, this 0.50 mm oversize piston ensures reliable performance and long engine life. ✔ Key Features & Technical Advantages OEM-spec M-7163-50 oversize piston (0.50 mm) Designed for cylinders machined or honed oversize by 0.50 mm Restores correct piston clearance and compression levels Reduces blow-by, oil consumption & exhaust smoke High-strength alloy construction for maximum durability Heat-resistant design suitable for heavy-duty diesel applications Precision-machined for smooth, efficient piston travel Ideal for full rebuilds, in-frame overhauls & corrective cylinder repairs
