The 612600020251 Engine Belt 8PK1062 is a precision‑engineered component that upholds the rigorous standards of SINOTRUK’s original equipment. Manufactured using high‑strength aramid or polyester tensile cords, a heat‑resistant ethylene‑propylene‑diene monomer (EPDM) rubber compound, and a precision‑ground ribbed profile, this belt ensures efficient power transmission, reduced slippage, and quiet operation.
The ribbed design provides superior flexibility while maintaining excellent grip on pulleys, even under high load and at elevated temperatures. With the 612600020251 reference number, this belt is precisely dimensioned to match the original 8PK1062 specification — 8 ribs and an effective length of 1062 mm — ensuring a perfect fit on SINOTRUK Howo WP12 engine accessory drives.
The belt’s construction resists cracking, glazing, and stretching, maintaining optimal tension and alignment throughout its service life. The EPDM material offers excellent resistance to ozone, oil, and extreme temperatures, making it ideal for both highway and off‑road applications.
Key Features
The EPDM compound and aramid cords of the 612600020251 belt resist cracking, glazing, and stretching, providing dependable service even in high‑temperature, high‑load engine compartments.
The precision‑moulded rib profile and optimised tooth geometry minimise vibration and noise, reducing driver fatigue and improving overall cabin comfort.
Manufactured to the exact 8PK1062 dimensions, this belt installs without adjustment issues, maintaining proper tension and alignment for maximum accessory drive efficiency.
Fleet Preventive Maintenance: Ideal for scheduled belt replacement programs, ensuring all trucks maintain optimal accessory drive performance and minimising the risk of unexpected belt failure.
Heavy-Duty Operations: Long‑haul, construction, and mining trucks benefit from the belt’s high strength and resistance to belt dust, oil, and extreme temperatures.
Emergency Repairs: A spare 612600020251 belt enables quick roadside replacement, reducing downtime and getting the vehicle back on the road promptly.
Every 612600020251 engine belt is manufactured in a state‑of‑the‑art facility under strict quality control, including tensile strength tests, elongation measurement, dynamic durability testing, and rib profile verification.
The EPDM rubber is compounded to resist ozone cracking and thermal ageing, while the aramid or polyester cords are treated to maintain dimensional stability and load‑carrying capacity over the belt’s lifetime.
The belt is designed to meet or exceed the original equipment performance standards, providing a service life typically ranging from 80,000 to 120,000 km under normal operating conditions. With the 612600020251, fleet operators can reduce unexpected breakdowns, improve accessory drive reliability, and lower overall maintenance costs.
Test Highlights
The 612600020251 engine belt is a direct replacement for the original belt on SINOTRUK Howo trucks equipped with the WP12 engine. It fits all models that use the 8PK1062 serpentine belt configuration, driving the alternator, water pump, power steering pump, and A/C compressor.
Before installation, check all pulleys for wear, alignment, and debris to ensure optimal belt life. Installation is straightforward: release the tensioner, remove the old belt, route the new 612600020251 belt around all pulleys following the decal diagram, and re‑apply tension.
Ensure the belt is fully seated in each pulley groove. After installation, start the engine and visually inspect the belt for proper tracking and tension. For best results, pair this belt with a new tensioner and idler pulleys during major service intervals.
