1005101BED30
This 1005101BED30 is a precision-engineered engine crankshaft, designed as a direct replacement for OE specifications. Manufactured from high-grade alloy steel, it undergoes rigorous forging and heat-treatment processes to achieve exceptional tensile strength and fatigue resistance. This ensures reliable performance under extreme engine pressures and rotational forces.
Dimensional accuracy is paramount. Each crankshaft is machined to micron-level tolerances, guaranteeing perfect balance and seamless integration into your engine assembly. This critical attention to detail minimizes vibrations, reduces wear on connected components like bearings and pistons, and contributes to overall engine longevity and efficiency.
Ideal for engine rebuilds and repairs, this crankshaft delivers the durability and performance required for demanding applications. It is the trusted choice for professional mechanics seeking a robust and reliable core engine component.
This crankshaft is forged from 4340 high-strength alloy steel, known for its exceptional toughness. It undergoes a precise heat treatment process, achieving a surface hardness of 55-60 HRC while maintaining a tough core. This dual-structure provides superior resistance to micro-welding and abrasion with counterweights, significantly increasing service life beyond standard OEM requirements. You get a component built to withstand extreme rotational forces and prevent premature failure.
Every journal surface on this crankshaft undergoes an advanced micro-polishing finishing process. This reduces surface roughness to an impressive Ra ≤ 0.1 µm, creating a mirror-like finish. The result is a significant reduction in friction with the bearing shells, leading to improved engine efficiency, lower operating temperatures, and enhanced oil film retention. This directly translates to increased horsepower and long-term reliability for the engine.
Imbalance is a primary cause of engine vibration and collateral damage. This crankshaft is dynamically balanced to an exceptionally low residual imbalance of less than 10 g·cm. This precision balancing ensures buttery-smooth operation across the entire RPM range, minimizing stress on the main bearings and the entire engine block. It guarantees a vibration-free performance that protects the entire rotating assembly.
We understand that fitment is non-negotiable. Every critical dimension—from journal diameters to flange run-out—is CNC-machined and verified to within 0.02mm of original equipment specifications. Furthermore, our manufacturing process is IATF 16949 certified, ensuring every part that leaves our factory meets the strictest international quality standards for automotive components. This guarantees a perfect, drop-in fit and reliable performance.

Here are specific application scenarios of Engine Parts Crankshaft:
Ideal for workshops specializing in complete engine rebuilds. When an engine suffers from a thrown rod, severe bearing wear, or catastrophic failure, this crankshaft serves as the foundational core for the rebuilt assembly. Its OEM-matching specifications and certified durability ensure the rebuilt engine meets or exceeds its original performance and service life, providing a reliable, long-term solution for your customers.
For engines subjected to higher stress from tuning or extended operation, the stock crankshaft can be a weak point. This component, forged from 4340 alloy steel and precision-balanced, offers a direct upgrade. It provides a significant safety margin for increased horsepower and torque, making it the preferred choice for performance builds and engines used in commercial or fleet vehicles requiring enhanced durability.
Proactively replace a worn crankshaft during a major service interval or when symptoms like persistent low oil pressure or unusual engine vibrations appear. Installing this crankshaft prevents sudden engine seizure and costly collateral damage to connecting rods, pistons, and the engine block. It is a strategic investment for maintaining fleet uptime and avoiding the higher cost of a complete engine replacement.
This crankshaft is a critical solution for vehicles that have experienced oil starvation or coolant contamination, common causes of crankshaft journal scoring and bearing failure. Its perfect OEM fit guarantees compatibility, allowing for a straightforward installation to restore the vehicle's engine to full operational integrity, whether for resale or continued use.
For optimal performance and to validate the warranty, professional installation by a certified mechanic is mandatory. Prior to installation, thoroughly clean the engine block and all oil galleries. Lubricate the main and connecting rod journals with a high-quality assembly lubricant. Precisely torque the main bearing cap bolts according to the manufacturer's specifications using a calibrated torque wrench, following the correct sequence and angle-tightening procedure. Always use new bearings and seals to ensure proper oil pressure and prevent leaks.
