Product Description

612600020373 Crankshaft Assembly is installed inside WEICHAI WP10 diesel engines and serves as the primary rotating shaft responsible for converting combustion force into usable engine output power.

Crankshaft journal wear, fatigue cracks, abnormal bearing clearance, poor lubrication, or imbalance may cause engine knocking, low oil pressure, excessive vibration, connecting rod damage, and severe engine failure.

This crankshaft assembly is widely used in export engine overhaul projects, heavy truck maintenance, engineering machinery repair, and commercial diesel engine rebuilding service.

Product Overview

This crankshaft assembly is commonly used on WEICHAI WP10 engine platforms installed in SINOTRUK HOWO, SHACMAN F3000, FAW heavy trucks, construction machinery, and industrial diesel equipment.

Common Field Failure Case

Case 1

Vehicle: SHACMAN F3000 Dump Truck
Mileage: 860,000 KM
Problem: Engine knocking and unstable oil pressure
Root Cause: Main journal wear and crankshaft bearing clearance exceeded tolerance
Solution: Replaced 612600020373 crankshaft assembly and bearings
Loss / Benefit: Restored engine stability and avoided complete engine seizure

Case 2

Vehicle: Engineering Machinery WP10 Engine
Mileage: 12,000 Working Hours
Problem: Severe engine vibration under heavy load
Root Cause: Crankshaft imbalance caused by long-term overload operation
Solution: Installed OE-standard dynamically balanced crankshaft assembly
Loss / Benefit: Improved engine smoothness and reduced internal wear

Case 3

Vehicle: Export Engine Overhaul Project
Mileage: Fleet Rebuild Application
Problem: Wrong crankshaft flange supplied
Root Cause: Different flywheel connection specification
Solution: Verified OEM number and flange dimensions before shipment
Loss / Benefit: Avoided assembly failure and repeat export freight expense
