Product Description

Product Features

Structure: Cast from high-strength vermicular graphite cast iron, with a 6-cylinder inline design and integrated coolant passages, oil galleries, and mounting points for engine components.
Performance: The vermicular graphite cast iron provides high rigidity, heat resistance, and fatigue strength, ensuring durability under heavy-duty operating conditions. Precision-machined cylinder bores ensure optimal piston fit and compression.
Design: Features replaceable cylinder liners, allowing for cost-effective engine overhaul without replacing the entire block. Integrated mounting brackets simplify installation of auxiliary components such as the oil pump and water pump.

Core Function

Serves as the main structural foundation of the engine, housing the crankshaft, connecting rods, pistons, and other internal components.
Maintains precise alignment of engine components to ensure efficient power transfer and reduce wear.
Contains coolant and oil passages to dissipate heat and lubricate critical parts, supporting stable engine performance.

Key Features and Benefits of Cylinder Block VG1500010383

Engineered for Maximum Engine Longevity

High-Strength Cast Iron Construction – Resists thermal fatigue, cracking, and deformation even under sustained high-load operation, extending engine overhaul intervals.
Precision-Machined Cylinder Bores – Ensures optimal piston-to-wall clearance for superior compression sealing and reduced oil consumption.
Integrated Coolant Passages – Engineered water jacket geometry promotes uniform heat dissipation across all six cylinders, preventing localized hot spots.
OEM Dimensional Accuracy – Direct-fit replacement with no modifications required, minimizing vehicle downtime during engine rebuilds.
Corrosion-Resistant Internal Surfaces – Treated to withstand coolant chemical exposure, protecting against cavitation erosion over hundreds of thousands of kilometers.

Cost-Efficiency for Fleet Operators

Factory-Direct Pricing – Eliminates middleman markups, delivering 20–35% cost savings compared to multi-tier distribution channels.
Reduced Rebuild Time – Drop-in fitment means your mechanics spend less time on alignment and more time getting trucks back on the road.
Bulk Order Availability – Ideal for fleet maintenance programs and engine remanufacturing workshops requiring consistent supply.

Frequently Asked Questions – Cylinder Block VG1500010383

Is VG1500010383 a direct replacement for my original HOWO cylinder block?

Yes. This cylinder block matches the original OEM dimensions, bolt patterns, and bore specifications of the WD615 engine series. It installs without any machining or modification, ensuring your engine rebuild proceeds smoothly and efficiently.

What is the expected service life of this cylinder block?

Under normal operating conditions with proper cooling system maintenance, the VG1500010383 cylinder block is engineered to support engine operation for 500,000+ kilometers before requiring inspection for wear or reconditioning.

How do I verify this is the correct part number for my truck?

Cross-reference the part number VG1500010383 with your engine nameplate data. This block fits WD615.47, WD615.69, WD615.87, and related sub-models. If you are unsure, send us your engine serial number and we will confirm compatibility within 24 hours.

Can this cylinder block handle engine performance upgrades?

The HT250 cast iron material and factory bore dimensions provide a solid foundation for standard rebuilds. For applications requiring overbore machining (up to +0.5 mm), the block wall thickness supports safe reconditioning while maintaining structural integrity.

What quality inspections are performed before shipping?

Each cylinder block passes through a multi-point inspection process including: dimensional verification of all bores and mounting surfaces, hydrostatic pressure testing of coolant jackets at 0.4 MPa, visual inspection for casting defects, and surface roughness measurement of cylinder bore walls.

How is the cylinder block packaged for international shipping?

Due to its weight (approximately 280 kg), each block is secured on a reinforced wooden pallet with anti-rust VCI film wrapping and foam cushioning to prevent transit damage. Custom export crating is available upon request.
