Mitsubishi Crankshaft for Fuso Fighter & Kobelco SK200 | 6D16/6D16T | ME072126

Forged Endurance for the 7.5L Mitsubishi 6D16 Powerhouse

The Mitsubishi 6D16 and its turbocharged variant, the 6D16T, are legendary 7.5L inline-6 diesel engines that form the backbone of mid-range commercial transport and heavy excavation. Powering thousands of Fuso Fighter logistics trucks and 20-ton Kobelco SK200 excavators worldwide, these engines are subjected to massive torque demands and continuous hydraulic loading. Because of the long inline-6 architecture, the crankshaft faces immense torsional stress. When the front harmonic fluid damper degrades over time, these destructive vibrations travel directly into the crankshaft, notoriously causing the front snout to snap or the first web to suffer fatal fatigue cracking.

Ruich Value re-engineers this critical powertrain component using advanced metallurgical processes. Unlike basic aftermarket castings, our ME072126 replacement crankshaft is forged from high-density 42CrMo steel alloy, drastically increasing its tensile strength and torsional rigidity. We then subject the massive 84mm main journals to deep induction hardening, pushing the surface hardness to a highly wear-resistant HRC 50-55. Whether you are overhauling a Kato HD820 excavator or maintaining a regional fleet of Fuso commercial trucks, this perfectly balanced crankshaft ensures your equipment returns to service with uncompromising reliability and extended bearing life.

Verified Commercial Truck & Heavy Equipment Fitment

The Ruich Value 42CrMo Forged Advantage

• Snapping Immunity: The dense forged grain structure of our 42CrMo steel absorbs the massive torsional spikes that cause standard cast 6D16 crankshafts to snap at the front web.
• Soot-Resistant Journals: Heavy-duty logistics operations generate abrasive soot. Our HRC 50-55 induction-hardened journals resist scoring and bearing spin during momentarily low oil pressures.
• Vibration Eradication: The 115mm stroke generates significant rotational mass. We dynamically spin-balance every ME072126 crankshaft to eliminate destructive harmonics, protecting the engine block.
• Precision OEM Fit: Machined to exact standard (STD) dimensions, our crankshafts guarantee perfect 84mm main bearing clearances out of the box, saving machine shop costs.
• Flawless Partner with us for commercial fleet Delivery: Each unit is rigorously MPI tested for internal defects, coated in thick anti-rust preventative, and locked into heavy-duty wooden crating for safe international export.
