612630020038 Crankshaft | WP12 Engine Parts For Truck & Machinery | Shacman

612630020038 Crankshaft is an original matching core spare part exclusively designed for Weichai WP12 series diesel engines. As the core power transmission component of the engine, it undertakes the task of converting the linear reciprocating motion of pistons into rotational mechanical energy, directly determining the power output, operational stability and service life of WP12 engines. This crankshaft is widely applied in heavy-duty trucks, engineering machinery, marine power equipment and large industrial supporting equipment equipped with Weichai WP12 engines, featuring high strength, wear resistance, fatigue resistance and stable power performance.

The WP12 engine is a mature high-power diesel engine launched by Weichai Power, with a displacement of 11.596L, power coverage of 258kW-368kW, and is widely used in 80-130t cranes, heavy-duty tractors, marine diesel engines and large agricultural machinery. The 612630020038 crankshaft strictly follows the original factory dimensional standards and process specifications, perfectly matching all models of the WP12 series engine, and is a reliable replacement part for engine maintenance, overhaul and assembly.

• Original Standard Matching: Part number 612630020038, 1:1 original factory size, completely compatible with all Weichai WP12 engine models, no modification required for direct installation.
• High-Strength Forging Process: Adopts high-precision integral forging technology, with dense material structure, strong compression resistance and impact resistance, effectively adapting to high-load and long-term continuous working conditions of engineering machinery and heavy trucks.
• Excellent Wear & Fatigue Resistance: The journal surface is treated with professional precision grinding and hardening process, which reduces piston linkage friction loss, avoids crankshaft deformation and fracture under high-frequency operation, and extends the overall engine service life.
• Stable Power Output: Strict dynamic balance calibration, low operational vibration, stable engine speed, effectively reducing engine failure rate and fuel consumption, improving the overall working efficiency of mechanical equipment.
• Strict Quality Control: All products pass dimensional inspection, hardness test, dynamic balance test and pressure resistance test, with zero defect rate of factory inspection, meeting international heavy-duty engine parts manufacturing standards.
