Dongfeng Dignity IX5 Driving Pulley1025100F0016 Assembly Product Introduction

The Driving Pulley Assembly plays a crucial role in the vehicle’s belt drive system, responsible for transmitting engine power to auxiliary components such as the alternator, power steering pump, and air conditioning compressor. Precision-engineered for high performance and long-lasting durability, this component ensures stable rotation, optimal belt tension, and minimal vibration during operation.

Driving Pulley1025100F0016Primary Functions:

Drive Power Transmission: This is its core purpose. The crankshaft pulley is directly bolted to the end of the crankshaft. As the engine runs, the rotational power of the crankshaft is transferred directly to this pulley. The serpentine belt (or V-belt) wraps around it, and this rotation drives all the engine's accessories, such as:
The alternator

The power steering pump
The air conditioning compressor
The water pump

Vibration Dampening (Harmonic Balancer): This is its most critical engineering function. The internal combustion process creates powerful torsional vibrations and pulses in the crankshaft. If left unchecked, these vibrations can cause severe damage to the crankshaft and connected components over time.

The pulley is not a single solid piece. It is typically a two-part assembly: a central hub and an outer ring.
These two parts are separated by a layer of specialized vibration-dampening rubber or a fluid-filled chamber.
This elastic layer allows the outer ring to twist slightly relative to the hub, absorbing and canceling out these destructive vibrations, hence the name "Harmonic Balancer."

Let’s break down the main perks of the Dongfeng Dignity IX5 Driving Pulley Assy (part number: 1025100F0016) in plain terms:
Fits perfectly, no hassle to replace
It’s made just for the Dongfeng Dignity IX5—exactly matching the original car’s specs. When you put it into the engine’s accessory drive system, it slots right in. No extra tweaks or changes needed when you swap out the old one.
Super tough, lasts way longer
We use high-quality alloy steel (and it goes through heat treatment too), so it can handle wear, knocks, and won’t warp even in high heat. That means it works great even in tough situations, like when you’re stopping and starting a lot. It lasts over 80,000 km—30% longer than those cheap generic replacement parts you find elsewhere.
Moves power efficiently, drives smoother
The grooves on the pulley are cut with a CNC machine—so precise, the error is only ±0.02 mm. That stops the belt from slipping as much. It also gets a dynamic balance test (meets ISO 1940 standard, G6.3 grade), which cuts down on vibration. So your ride feels more comfortable, and it protects the other parts connected to it too.
Won’t rust, even in bad weather
It has two layers of protection: first an electrophoretic coating, then a clear sealant. Together, they keep out moisture, road salt, and oil. So it works fine in harsh climates—no rust messing up how it performs.
Good seals & bearings (if it has them)
It comes with rubber seals that can handle high heat—up to 200°C—to keep the bearings safe. The bearings are car-grade too, so they can keep up with what the engine needs to output.
