The 201V95800-6099 flywheel pulley is precision‑cast from high‑strength nodular cast iron (GGG‑50), offering excellent tensile strength and fatigue resistance. The multi‑groove V‑profile is machined to tight tolerances, ensuring optimal belt grip and minimizing slippage. Each pulley is dynamically balanced to G6.3 grade to eliminate vibration, protecting bearings and extending the life of the accessory drive system. The hub is precision‑bored to match the flywheel flange, ensuring a secure, concentric fit.
Every 201V95800-6099 pulley undergoes 100% inspection, including dimensional checks for groove angle, runout, and surface finish. A magnetic particle test is performed to verify material integrity and detect any cracks. The pulley is then coated with a rust‑inhibiting primer, ready for installation. This rigorous quality control guarantees that the pulley will provide reliable power transmission and long service life under the most demanding conditions.

The 201V95800-6099 flywheel pulley is a direct OEM replacement for Howo engines, including the MC07, MC11, MC13, and WD615 series. It is mounted directly to the flywheel or crankshaft flange and drives the serpentine belt that powers critical accessories such as the alternator, water pump, power steering pump, and air conditioning compressor. A properly functioning pulley ensures that all accessories operate at the correct speed, maintaining charging, cooling, and steering assist.
In heavy‑duty applications, the flywheel pulley is exposed to constant vibration, heat, and belt tension. A worn or damaged pulley can cause belt slip, noise, and eventual accessory failure. The genuine 201V95800-6099 pulley maintains precise groove geometry and concentricity, ensuring quiet, efficient power transmission and long belt life. It is also used in remanufactured engines and as a standard replacement part during major overhauls.
When replacing the flywheel pulley, always check the condition of the belt and tensioner. Replace the belt if it shows signs of wear or glazing. Use a new flywheel bolt and torque to specification.
Correct installation of the 201V95800-6099 flywheel pulley is critical to ensure proper belt alignment and long service life. Follow these steps:
Remove the fan belt and any accessories blocking access. Clean the flywheel mounting surface and the pulley bore. Inspect the flywheel for cracks or damage.
Align the pulley with the flywheel dowel pin and insert the mounting bolts. Torque the bolts in a criss‑cross pattern to the specified value (typically 80‑100 Nm). Install the belt and adjust tension.
Rotate the engine by hand to verify smooth belt tracking. Start the engine and check for vibration or unusual noise. Re‑check belt tension after a short run.
A worn or damaged flywheel pulley can cause accessory drive problems. Common signs that replacement is needed include:
If any of these symptoms are observed, immediate replacement with a genuine 201V95800-6099 pulley is recommended. Continuing to operate with a worn pulley can lead to belt failure, overheating, and loss of power steering or charging.
Precision‑machined grooves and dynamic balancing ensure efficient belt drive, minimizing slip and maximizing accessory performance.
The smooth, concentric groove surfaces reduce belt wear, extending replacement intervals and lowering maintenance costs.
Manufactured to original specifications, the pulley bolts on without modification and withstands the rigors of heavy‑duty operation.
To maximize the service life of your 201V95800-6099 flywheel pulley, follow these best practices:
By adhering to these guidelines, you ensure that the 201V95800-6099 pulley performs optimally throughout its intended service interval.
Aftermarket flywheel pulleys are often made from inferior cast iron with poor machining, leading to imbalance, premature wear, and belt damage. The genuine 201V95800-6099 is manufactured to the exact specifications of the original equipment, using high‑grade nodular iron and precision CNC machining. Each pulley is balanced and inspected for runout, guaranteeing that it will perform exactly as the original part.
By choosing authentic SINOTRUK HOWO parts, you protect your investment and ensure your truck maintains its reliability and resale value. The Sinotruk howo parts catalog includes a full range of engine and chassis components engineered for maximum durability. For fleet managers and owner‑operators who demand the best, the genuine 201V95800-6099 is the only responsible choice.
The 201V95800-6099 flywheel pulley is used across a wide range of Howo models: T7H, A7, and classic Howo‑7 series equipped with MC07, MC11, MC13, and WD615 engines. Always verify the number of grooves and the bolt pattern using the service manual.
Each 201V95800-6099 is individually wrapped in protective oiled paper to prevent rust. The packaging is clearly labelled with the OEM number and batch code. For bulk orders, pulleys are shipped in sealed cartons with foam inserts to avoid transit damage.
Production of the 201V95800-6099 takes place in IATF 16949 certified facilities, using precision casting and CNC machining with in‑process gauging. Statistical process control ensures that dimensional variations are kept to a minimum, far exceeding the requirements of the original design.
