Introduction

The 81560040037 Exhaust Valve Seat is a core precision engine component specially designed for WEICHAI diesel engines, widely used in heavy-duty trucks, construction machinery and commercial vehicles. As a key sealing part of the engine exhaust system, it cooperates closely with the exhaust valve to achieve precise valve sealing, efficiently discharge exhaust gas, and prevent gas leakage during engine operation. Working in high-temperature, high-pressure and high-frequency impact environments for a long time, this valve seat adopts high-temperature resistant alloy material and precision machining technology. It features excellent hardness, thermal stability and abrasion resistance, effectively solving common engine faults such as poor sealing, exhaust leakage, power drop and excessive fuel consumption caused by worn or deformed valve seats. It is a standard OEM replacement part for WEICHAI engine overhaul and daily maintenance.

Key Features

✅️100% OEM Standard Exact Fit 

Manufactured strictly in accordance with WEICHAI original factory technical specifications with standard part number 81560040037. The outer diameter, inner hole precision, assembly radian and sealing angle fully match the original engine parameters. No modification is required for direct press-in installation, perfectly compatible with supporting WEICHAI engine models.

✅️Precision Machining & Zero Leakage Sealing 

Processed by high-precision CNC grinding and fine finishing, the sealing surface is smooth and flat with accurate angle. It achieves tight fitting with the exhaust valve, completely avoids exhaust gas leakage, ensures stable engine cylinder pressure, and maintains optimal combustion efficiency and power output.

✅️Restore Engine Original Performance 

Effectively solves typical engine problems such as black smoke emission, weak power, difficult startup, unstable idling and increased fuel consumption caused by aging and damage of exhaust valve seat. It fully restores engine sealing performance and exhaust efficiency, improving overall engine working stability.

✅️Excellent Impact & Wear Resistance 

The overall structure is compact and firm with strong fatigue resistance. It can withstand high-frequency collision and friction between the valve and valve seat during long-term engine operation, effectively reducing wear loss and avoiding valve seat sinking and sealing failure.

✅️Cost-Effective & Widely Applicable 

Factory direct supply with strict hardness testing and sealing inspection, reaching OEM quality standard with competitive price. Suitable for WEICHAI series diesel engines equipped on heavy trucks and engineering machinery, it is a hot-selling aftermarket part for Middle East, Africa, Central Asia and other global overseas markets.
