Yuwei Piston (Suitable for Weichai WP10 Engine) Product Details

I. Product Introduction

Yuwei Pistons are specially designed for Weichai WP10 series engines, covering six core models: 612600030047, 612640020034, 612600030068, 612600030024, VG1246030001, and 612650020002. As a core component of the engine cylinder, it transmits the pressure of high-pressure gas generated by fuel combustion to the crankshaft to drive the engine. Adhering to Weichai's original factory technical standards, it is perfectly compatible with WP10 engines and suitable for heavy-duty trucks, buses, construction machinery, generator sets, etc., ensuring efficient and long-term operation of the engine.

II. Product Positioning

Yuwei Piston is positioned as a high-end dedicated piston for Weichai WP10 engines, focusing on two core scenarios: supporting medium and heavy-duty equipment and after-sales maintenance replacement. Compared with ordinary auxiliary factory pistons, it has the advantages of original factory standards, precise adaptation and long service life; compared with original factory pistons, it has higher cost performance, creating a cost-effective first-choice brand for Weichai WP10 engine pistons.

III. Model Adaptation

All models of Yuwei Pistons are precisely suitable for Weichai WP10 series engines (including national III, national IV and other emission versions, with power covering 121-280kW). The specific adaptation information is as follows:

Model 612600030047

Suitable for various heavy-duty trucks and construction machinery equipped with WP10 engines, strong versatility, no additional modification required for installation.

Model 612640020034

Focus on construction machinery (such as loaders, excavators), with stronger impact and wear resistance, suitable for harsh operating environments.

Model 612600030068

Suitable for logistics transport heavy-duty trucks, optimized lightweight design to reduce fuel consumption.

Model 612600030024

Suitable for buses (passenger and public transport), with low noise and low energy consumption, meeting the needs of high-frequency operation.

Model VG1246030001

Suitable for high-power WP10 models (such as large generator sets, heavy-duty tractors), with strong pressure and high-temperature resistance.

Model 612650020002

Universal model, suitable for all equipment equipped with WP10 engines, convenient for after-sales replacement and inventory management.

Note: All models are completely consistent with the installation size and assembly standards of Weichai WP10 engine pistons, compatible with original piston rings and piston pins, and can be directly replaced.

IV. Product Advantages

Precise Adaptation, Easy Installation

Produced in accordance with Weichai's original drawings and technical parameters, all models have passed actual machine installation tests. The key parts are optimized, fitting closely with engine components, no additional polishing or modification required, greatly improving installation efficiency.

High-Quality Material, Strong Durability

Made of high-quality cast aluminum alloy, treated with special strengthening processes, with excellent high-temperature, high-pressure, wear and deformation resistance. The piston head is designed with an internal cooling oil channel to reduce working temperature; the piston pin hole is optimized to reduce friction loss. Its service life is far longer than ordinary auxiliary factory pistons, close to the original factory level.

Stable Performance, Power Improvement

Optimized "ω" combustion chamber design improves fuel combustion efficiency and engine power output. The piston surface is precision polished to reduce friction resistance, lower noise and energy consumption. All products pass strict sealing, pressure and wear tests before leaving the factory to ensure stable operation.

High Cost Performance, Worry-Free After-Sales Service

With original factory quality and no brand premium, it saves procurement and maintenance costs for users. It provides perfect after-sales guarantee, supports return and exchange for quality problems, and has a professional technical consulting team to provide comprehensive services.

V. Installation and Maintenance

(I) Installation Notes

Before installation, check the piston surface for defects, clean the engine cylinder, and ensure the cylinder has no serious wear or deformation.
Use special installation tools, avoid violent knocking; pay attention to the opening position of piston rings, and apply appropriate special lubricating oil when installing piston pins.
Ensure the correct installation direction of the piston, and do not install it reversely.
After installation, manually rotate the crankshaft to check for smooth operation; start the engine to check for air leakage, oil leakage and abnormal noise.

(II) Daily Maintenance Points

Regularly check the engine oil level and quality, use special oil for Weichai WP10 engines, and replace oil and oil filters regularly.
Regularly check the cooling system to avoid engine overheating, which may damage the piston.
Avoid long-term overload and overspeed operation of the engine, and arrange the operation rhythm reasonably.
Regularly overhaul the engine, check the piston wear, and replace the piston in time if there is any abnormality.
When the equipment is out of service for a long time, maintain the engine comprehensively to prevent piston rust and corrosion.
