Introduction

OEM No.: VG2600060313

This is a high-precision OEM-standard automatic belt tensioner tailored for SINOTRUK heavy-duty trucks, perfectly matching WEICHAI engine-equipped HOWO, A7 and Golden Prince series models. As a core driving component of the engine accessory system, it automatically adjusts the tightness of fan belts and generator belts during engine operation. It keeps stable belt tension at different speeds, effectively solving belt slipping, loosening, shaking and abnormal wear problems. Produced fully according to original factory technical standards, it features accurate mounting size and 100% interchangeability. Widely used on SINOTRUK tractors, dump trucks, water tank trucks and construction vehicles, it serves as a durable and cost-effective replacement part for global heavy truck aftermarket markets.

Key Features

✅ 1. Standard OEM Dimension, Plug-and-Play Installation

Manufactured strictly in accordance with OEM specification VG2600060313. All mounting holes, installation spacing and wheel surface parameters are completely consistent with original parts. No modification or professional debugging is required during replacement, realizing fast and accurate installation. It perfectly fits the original belt and engine assembly without offset or matching failure.

✅ 2. Automatic Tension Adjustment, Stable Transmission Efficiency

Adopts high-sensitivity internal spring damping structure, which can automatically compensate belt elongation and wear changes caused by long-term operation. It maintains constant and uniform belt tension at high and low engine speeds, effectively preventing belt slipping, power loss and overheating. It ensures stable operation of fan, generator and other accessory equipment to guarantee normal engine heat dissipation and power supply.

✅ 3. High-Precision Bearing & Low Noise Operation

Equipped with high-grade sealed precision bearing with smooth rotation and low friction coefficient. The integrated structural design effectively reduces running resistance and mechanical noise. It avoids abnormal squeaking and jitter caused by poor bearing operation, ensuring quiet and stable operation of the entire engine transmission system.

✅ 4. High Temperature & Fatigue Resistance, Ultra Durable

The tensioner shell adopts high-strength alloy material, and the internal spring and damping parts are made of high-temperature resistant materials. It can adapt to long-term high-temperature working environment in the engine compartment, resisting thermal aging, structural fatigue and deformation. It maintains sensitive tension adjustment performance after long-distance and heavy-load driving, greatly extending the service life of the belt and tensioner assembly.

✅ 5. Excellent Vibration Resistance for Harsh Conditions

Optimized damping buffer structure effectively absorbs engine vibration and road bump impact. It is specially adapted to mining muddy roads, bumpy rural roads and tropical high-temperature dusty environments. It is not easy to loosen or fail under continuous vibration and alternating load, perfectly meeting the harsh working requirements of African engineering and logistics fleets.

✅ 6. Strict Factory Testing & Cost-Effective Wholesale

Each belt tensioner passes strict rotation test, tension calibration test and high-temperature aging test before delivery to ensure stable performance and low failure rate. With factory direct sales advantage and sufficient stock, it supports sample orders and large batch wholesale, providing reliable spare parts supply for repair shops, dealers and fleet companies worldwide.
