Mitsubishi S4S Crankshaft (32A11-00100) for Forklift Fleets

The Forged Steel Heart for Your Material Handling Fleet

The Mitsubishi S4S diesel engine is one of the most trusted and widely deployed powerplants in the global material handling industry. Renowned for its proven job-site reliability, it serves as the core of countless 2-ton to 3-ton forklifts from Mitsubishi, Caterpillar, and other major brands. This specific application—characterized by thousands of rapid forward/reverse directional changes per shift—places a unique and punishing load on the crankshaft’s thrust bearing surface. Over time, this constant shock loading can cause excessive end play, leading to “crank walk,” oil pressure loss, and ultimately, catastrophic engine failure.

The Ruich Value 32A11-00100 crankshaft is engineered as the definitive solution for this specific industrial pain point. We begin by forging the crankshaft from high-density 42CrMo steel, creating a component with far greater structural rigidity than standard cast iron. Crucially, we then apply a specialized induction hardening process not only to the main and rod journals but also to the thrust bearing faces. This creates an ultra-durable HRC 50-55 surface that resists the intense lateral forces of forklift operation. For fleet managers seeking to maximize uptime and reduce long-term maintenance costs, our forged S4S crankshaft offers unmatched reliability and performance.

The Ruich Value Forged Advantage for S4S Engines

• Thrust Failure Immunity: Our specialized hardening process fortifies the thrust bearing faces, preventing the excessive wear and “crank walk” common in high-cycle forklift applications.
• Superior Strength: Forged from high-density 42CrMo steel, this crankshaft offers significantly higher fatigue resistance than the standard cast iron OEM part, preventing cracks.
• Abrasive Wear Defense: HRC 50-55 induction hardened journals create an ultra-durable shield against scoring from dust and soot contamination in industrial settings.
• Vibration-Free Operation: Each unit is dynamically spin-balanced to eliminate harmful vibrations, protecting the oil pump, engine block, and hydraulic systems from premature wear.
• Global export Supply Chain Ready: We maintain a robust inventory of 32A11-00100 crankshafts for immediate wholesale dispatch, ensuring your fleet maintenance schedule is never compromised.
