3. High-quality installation with compliance with torques: correct fit of the pulley guarantees a long service life and stable operation of all systems.

4. Use of high-quality damper pulleys: we install only proven components that can withstand the loads of modern engines and have a long service life.

Timely replacement of the crankshaft pulley helps:

1 Prevent the poly-V belt from breaking and related breakdowns.

2 Avoid excessive wear of the generator, rollers and power steering pump.

3 Reduce vibrations and noise in engine operation, especially at idle.

4 Ensure stable and uninterrupted operation of attachments.

5 Extend the overall service life of the engine and related systems.

What is a crankshaft pulley?

The crankshaft pulley is an engine part located at the front end of the crankshaft. It performs an important function – it transmits rotational motion to other vehicle systems, including the generator, pumps, belts and other units. It is a key element that ensures the stable operation of auxiliary equipment.

The crankshaft pulley is also called:

• a damper pulley

Заміна шківа колінвала

• a poly-V-belt pulley with a damper

These are all variants of the names of the same design, which performs the function of damping torsional vibrations of the crankshaft.

Purpose of the crankshaft pulley:

Dampens resonant torsional vibrations of the crankshaft
Reduces vibrations during engine operation
Reduces wear of generator bearings, tension and bypass rollers
Protects the poly-V belt from jerks
Ensures smoother and more stable operation of the diesel engine

Types of crankshaft pulleys:

Conventional pulley — a solid metal structure
Damping pulley — consists of three main parts:

- inner part (hub)
- outer ring (working surface)
- rubber damper (elastic connecting element)

In more complex systems, for example with stop-start technology or on powerful diesel engines, the pulley design can be even more complex.

When is the crankshaft pulley required to be replaced?

Every 100,000 – 120,000 km of mileage (recommendation of automakers)
When vibrations or extraneous noises appear from the belt drive
In the event of a break or rapid wear of the poly-V belt
During scheduled maintenance — for a preventive inspection

Why does the problem arise?

Many diesel car owners have encountered a sudden break in the generator drive belt. It seems that everything was correct: the belt was replaced on time, there was no extraneous noise. But under the hood — a “noodle” of belt remnants.

The reason lies in the design features of the damper pulley. Between its inner and outer parts there is a rubber layer that dampens torsional vibrations. This element gradually wears out under the influence of temperature changes, moisture and mechanical loads.
