The SP137005 is a high-performance drive belt designed for SINOTRUK Howo A7, T7H, and other heavy-duty truck models. This belt is responsible for transferring power from the engine’s crankshaft to the alternator, water pump, cooling fan, and other auxiliary components. Its OEM-grade construction replicates the original belt’s length, width, rib profile, and tensile strength, ensuring a perfect fit and optimal power transmission.
Manufactured from high-quality EPDM (ethylene propylene diene monomer) rubber, the SP137005 belt offers superior resistance to heat, ozone, and weathering compared to conventional rubber belts. The belt is reinforced with high-strength fabric cords that provide excellent tensile strength and resistance to stretching, ensuring consistent tension and reliable power transfer over the belt’s service life. The precision-molded ribs are designed to mesh perfectly with the pulleys, reducing slippage and noise while maximizing efficiency.
The SP137005 belt is engineered to withstand the harsh conditions typical of heavy-duty truck operation – including extreme temperatures, high engine loads, and exposure to dirt, oil, and road chemicals. Its durable construction ensures long service life and reduces the frequency of belt replacements, minimizing downtime and maintenance costs.
Common signs of a failing drive belt include visible cracks or fraying, squealing noises during startup or acceleration, dimming headlights (indicating alternator underperformance), and engine overheating (due to reduced water pump speed). Replacing a worn belt with the SP137005 restores full power to all auxiliary systems, ensuring reliable operation and preventing costly component failures.
Whether you’re performing scheduled maintenance or addressing a belt failure, the SP137005 Belt offers the quality, durability, and precision fit that SINOTRUK Howo owners and technicians trust.
The SP137005 Belt is specifically designed for SINOTRUK Howo A7 and T7H series trucks, as well as other models equipped with compatible auxiliary drive systems. This belt serves as a direct replacement for the original factory belt and is compatible with a wide range of engine configurations, including the WD615, D10, and MC series powerplants.
This belt is used to drive essential auxiliary components including the alternator (for battery charging), water pump (for engine cooling), cooling fan, and air conditioning compressor. Its precise length and rib profile ensure proper tension and alignment across all pulleys, preventing premature wear and ensuring reliable operation of all driven components.
In demanding applications such as long-haul transport, construction, and mining, the drive belt is subjected to high loads, temperature extremes, and exposure to contaminants. The SP137005 is engineered to withstand these harsh conditions, providing consistent power transmission and reducing the risk of belt failure that could lead to overheating, electrical issues, or loss of cabin climate control.
When replacing a belt, it is recommended to inspect the tensioner and pulleys for wear or damage, as these components can affect belt life and performance. The SP137005 is designed to work with the factory pulley system, ensuring optimal belt tension and alignment for maximum service life.
Replacing the SP137005 belt is a straightforward procedure that can be completed with basic hand tools. Begin by safely parking the truck and allowing the engine to cool. Locate the belt tensioner – typically a spring-loaded pulley that maintains proper belt tension. Using a breaker bar or socket wrench on the tensioner’s center bolt, rotate the tensioner to release pressure on the belt.
Remove the old belt from the pulleys, taking note of the routing path for reference. Compare the old belt with the new SP137005 belt to verify that the length, width, and rib count match. Route the new belt over the pulleys according to the routing diagram (often found on a label under the hood), ensuring the ribs are properly seated in the pulley grooves.
Release the tensioner slowly, allowing it to apply tension to the new belt. Verify that the belt is properly seated on all pulleys and that there is no twisting. Start the engine and observe the belt for any unusual noise or vibration – if squealing occurs, re-check the belt routing and tension. The SP137005 belt is designed for easy installation and is widely used by technicians and mechanics.
For maintenance, regularly inspect the belt for signs of cracking, fraying, glazing, or uneven wear. Check belt tension periodically and adjust if necessary. Replace the belt if any damage is detected or at the manufacturer’s recommended service intervals. The SP137005 is designed for long service life, but regular visual inspections during routine maintenance are essential for preventing unexpected failures.
When replacing the belt, it is also a good practice to inspect the tensioner and idler pulleys for wear, roughness, or noise, and replace them if necessary to ensure optimal belt performance and longevity.
The SP137005 Belt is manufactured in an ISO 9001-certified facility using advanced rubber compounding and molding processes. The EPDM compound is formulated to meet SINOTRUK’s precise specifications for hardness, tensile strength, and temperature resistance, ensuring consistent performance and durability.
Each belt undergoes a series of quality checks, including dimensional verification, tensile strength testing, and visual inspection for surface defects. The fabric reinforcement is tested for adhesion and strength, and the ribs are inspected for proper profile and spacing. Random samples from each production batch are subjected to accelerated aging tests and dynamic belt performance testing to verify long-term reliability.
We back the SP137005 with a comprehensive warranty against material and workmanship defects. Our rigorous quality control ensures that every belt delivers the same performance, fit, and reliability as the original factory part, giving you confidence in your truck’s auxiliary drive system.
