Description

Piston M-7416-50 (0.50 mm) The M-7416-50 Oversize Steel Crown Piston Set (x4) is an OEM-grade, high-performance piston set engineered for diesel engines requiring a 0.50 mm oversize piston due to cylinder wear, machining, or reboring. Featuring a robust steel crown , this piston set delivers superior resistance to extreme combustion temperatures, high boost pressure, and the demanding loads of commercial diesel operation. Compared to standard aluminum pistons, the steel crown design offers exceptional durability, preventing crown erosion, cracking, and thermal fatigue. Each piston is precision-machined to restore correct piston-to-liner clearance, enhance ring sealing, improve compression, and reduce friction—resulting in smoother operation and long-term reliability. This set of 4 oversize pistons replaces OEM reference 3926633 , ensuring a direct, OEM-spec fit for engines requiring machining corrections or performance-grade rebuilds. ✔ Key Features & Technical Advantages OEM-spec M-7416-50 0.50 mm oversize steel crown piston set (x 4) Designed for cylinders machined or rebored 0.50 mm oversize Steel crown construction ensures maximum heat resistance and structural strength Enhances sealing, compression stability & fuel efficiency Reduces blow-by, oil burning, smoke & piston slap Precision-machined skirts & ring grooves for smooth operation Ideal for turbocharged, high-load & heavy-duty applications Direct replacement for OEM 3926633
