Searching for a reliable MD302012 crankshaft replacement? This high-tensile forged steel assembly is engineered to eliminate front snout snapping and keyway shear in 2.5L diesel engines. It provides exact fitment for Mitsubishi L200/Pajero and Hyundai H100/Starex fleets. In stock for immediate Global export solutions.
The Mitsubishi 4D56 and its Hyundai counterpart, the D4BA/D4BB series, are among the most prolific 2.5L diesel engines in the world, powering legendary workhorses like the L200 pickup and the H100 van. However, these engines share a notorious mechanical vulnerability: front snout snapping and keyway shear. This failure is typically triggered by a loose harmonic balancer bolt or a degraded vibration damper, which allows harmonic frequencies to tear through the crankshaft snout, leading to catastrophic timing failure and engine destruction.
Ruich Value addresses this critical failure point with our premium MD302012 replacement crankshaft. Forged from high-density 42CrMo steel alloy—vastly superior to standard cast iron alternatives—this unit offers the structural integrity required to withstand extreme torsional stress. Every crankshaft undergoes rigorous induction hardening on the journals and snout to achieve an HRC 50-55 hardness, specifically protecting the keyway area from premature wear. Whether you are maintaining a fleet of commercial delivery vans or rebuilding a 4×4 Pajero, our dynamically balanced crankshaft ensures your engine returns to the road with maximum durability and zero compromises.

Snapping is usually the result of a “wobbling” harmonic balancer. If the crank bolt is not torqued to the strict 170-190 Nm specification, or if the rubber damper in the pulley has perished, the vibration shears the keyway and snaps the snout. Our forged 1100A135/MD302012 upgrade offers the tensile strength needed to handle these shocks, but replacing the harmonic balancer and crank bolt is mandatory.
No. The MD302012 profile is designed for the 8-valve mechanical injection engines (4D56 / D4BA). The newer 16-valve Common-Rail (DI-D) 4D56U engines use a different crankshaft (often OEM 1100A135) with different balancing and snout configurations. Always verify your engine code before ordering.
Bearing wear in these engines is often caused by oil contamination. In high-mileage H100 or L200 fleets, carbon soot from mechanical injectors can overwhelm the oil filter, creating an abrasive paste. Our induction-hardened journals (HRC 50-55) provide a robust shield against this scoring, but strict 5,000km oil change intervals are essential for longevity.
No. All of our brand-new MD302012 crankshafts are precision-ground to exact OEM standard (STD) specifications (66.00 mm main journals, 52.50 mm rod journals). Simply order a new set of high-quality STD main bearings, connecting rod bearings, and thrust washers for a factory-spec rebuild.
To ensure zero transit damage to the precision journals, every order is coated in industrial rust-preventative, wrapped in a moisture-blocking VCI bag, and securely packed inside a reinforced, export-grade wooden crate. We guarantee flawless delivery to our partners worldwide.
