6304924F Engine Crankshaft Fits Cummins Engine Power Output Shaft Replacement Part

Product Overview

6304924F Engine Crankshaft (CRANKSHAFT,ENGINE) is the core power transmission component of Cummins series diesel engines. Installed inside the engine cylinder block, it converts the linear thrust generated by piston combustion into rotational torque to drive vehicle transmission, generator, air compressor and other auxiliary equipment.

This crankshaft solves serious engine failures such as journal wear, crack fracture, abnormal knocking and power loss caused by long-term overload operation, poor lubrication or aging of old crankshafts, and is a key replacement part for major engine overhaul.

Core Product Advantages

1. High-Strength Integral Forged Alloy Steel

   Adopts special alloy steel integral forging, overall quenching and tempering heat treatment, ultra-high tensile strength and impact resistance, withstand long-term full-load torque impact without bending or fracture.

2. Journal Precision Grinding & Surface Hardening

   Main journal and crank pin surface high-frequency quenching + fine grinding, ultra-low surface roughness, excellent wear resistance, greatly reduce friction loss with bearings and extend service life.

3. Optimized Counterweight Balance Design

   Precision dynamic balance calibration for each counterweight, effectively offset reciprocating inertial force, reduce engine vibration and running noise, improve overall stability.

4. Smooth Oil Passage Processing

   Precision drilled internal lubricating oil passages with burr-free inner walls, smooth oil circulation to form stable oil film, avoid dry friction and journal ablation.

5. Wide Temperature & Load Adaptability

   Stable mechanical performance under -40℃ ~ +135℃, no thermal deformation under long-time high-temperature and heavy-load operation.

6. Standard Original Matching Installation Structure

   Standard flange, gear tooth and thread positioning, perfectly match Cummins engine cylinder block assembly, no secondary machining required during overhaul replacement.

7. Strict Multi-Process Factory Inspection

   All crankshafts pass magnetic particle flaw detection, dynamic balance test, dimensional tolerance inspection and hardness test, stable batch quality for engine overhaul factories and large logistics fleets.
