Crankshaft Pulley with Dampener – Porsche 958 Cayenne / 970
Panamera Hybrid
Restore smooth and reliable engine operation with this OE
Match Crankshaft Pulley with Dampener. The crankshaft pulley is mounted to the front of the
crankshaft and drives the auxiliary belt system. Its integrated vibration
dampener also helps absorb torsional vibrations generated by the engine,
reducing stress on the crankshaft and belt-driven components.

What Does the Crankshaft Pulley with Dampener Do?
As the engine runs, the crankshaft produces small twisting vibrations with each combustion cycle. The dampener helps absorb these vibrations before they are transferred through the crankshaft and auxiliary drive system.
The pulley also transfers crankshaft rotation to the auxiliary drive belt.
A correctly functioning crankshaft pulley helps:
- Drive the auxiliary belt system
- Reduce crankshaft torsional vibration
- Maintain smooth belt operation
- Reduce vibration transmitted to engine components
- Protect associated pulleys and belt-driven equipment
- Support smooth engine operation
Why Do Crankshaft Pulleys and Dampeners Fail?
The dampener is exposed to constant vibration, heat and engine speed changes. Over time, the rubber damping material between the pulley sections can deteriorate, crack or separate.
Common causes include:
- Age-related rubber deterioration
- Repeated heating and cooling cycles
- Engine vibration
- Contamination from engine oil or other fluids
- Cracking or separation of the damping material
- Pulley distortion or damage
- High mileage and general wear
Once the damping material deteriorates, the inner and outer sections of the pulley can begin moving independently.
When Should the Crankshaft Pulley Be Replaced?
Replacement should be considered if:
- The pulley visibly wobbles while the engine is running
- Cracks appear in the rubber dampening section
- The rubber begins separating from the pulley
- Unusual vibration develops from the front of the engine
- The auxiliary belt runs unevenly
- Squeaking, knocking or rattling noises are present
- The pulley is physically damaged or distorted
- Inspection confirms deterioration of the dampener
A failing crankshaft pulley should not be ignored, as complete separation can affect the auxiliary drive system and potentially damage surrounding components.
Important Auxiliary Drive Checks
When replacing the crankshaft pulley, inspect the auxiliary drive belt, tensioner, idler pulleys and surrounding components for wear or damage.
Any oil or coolant leaks contaminating the pulley should also be repaired, as fluids can accelerate deterioration of the rubber damping material.
Porsche Cayenne 958 & Panamera 970 Hybrid Crankshaft Pulleys
The crankshaft pulley and vibration dampener form an important part of the engine's auxiliary drive and vibration-control system.
As Porsche Cayenne 958 and Panamera 970 Hybrid models age, the rubber damping element can deteriorate through heat, vibration and general wear. Typical signs include pulley wobble, abnormal vibration, belt movement and noise from the auxiliary drive area.
During diagnosis, the pulley should be inspected alongside the auxiliary belt, tensioner and idler pulleys to identify any additional worn components.

The OE Match Cam Idler Roller is a high-quality replacement timing belt guide roller designed to support and guide the camshaft timing belt within the engine timing system. Featuring an outer diameter of 32mm and a width of 21mm, this precision-engineered idler roller helps maintain correct belt routing, alignment and stability throughout engine operation.
Fits:
- Porsche 924S 2.5L 1986-87
- Porsche 944 2.5L 8V 1982-87
- Porsche 944 Turbo 2.5L 8V 1985-88

Manufactured to OE specifications for fit, function and durability, the roller is designed to withstand constant rotational loads, engine heat and high-speed operation. It is an essential service component during timing belt replacement and engine maintenance, helping to ensure reliable timing system performance and long-term engine protection.
What This Product Does:
- Guides and supports the camshaft timing belt.
- Maintains correct timing belt alignment and routing.
- Reduces belt vibration and unwanted movement.
- Promotes even belt wear across the timing system.
- Helps ensure accurate synchronisation between the crankshaft and camshaft.
- Supports smooth and reliable engine operation.
Symptoms Of Wear Or Failure:
- Squealing, chirping or grinding noises from the timing belt area.
- Excessive timing belt vibration.Rough or noisy bearing operation.
- Visible wear on the roller surface.Timing belt misalignment.
- Uneven or accelerated timing belt wear.
- Bearing play or looseness within the roller.
- Timing belt failure risk in severe cases.
Why Replacement Matters:
- The cam idler roller operates continuously whenever the engine is running and is subjected to constant rotational speeds, heat and bearing loads. Over time, the internal bearing can wear, lubrication can deteriorate and the roller surface may become damaged.
- A failing idler roller can cause timing belt misalignment, increased belt wear and excessive stress on other timing system components. In severe cases, bearing seizure or roller failure can lead to timing belt damage, potentially resulting in significant engine damage and expensive repairs.

• Position on Vehicle: his part mounts in the timing belt drive system (camshaft-belt/guide roller area) on the front of the engine block, often adjacent to the belt guard/rail for the water pump/temporal belt path.
• Applications: Timing belt drive systems in the above-listed Porsche models (924S, 944, 968). Suitable replacement when restoring or maintaining correct cam/ crank timing and belt drive reliability.
The timing belt idler roller plays a crucial role in maintaining precise belt alignment and smooth engine operation. Over time, the bearing can wear out or seize, risking belt failure and serious engine damage. Replacing the roller during scheduled maintenance ensures long-term reliability, quiet operation, and protection of vital engine components.
When and why to replace:
• Signs of wear, noise, or rough bearing movement.
• During timing belt or water-pump service for easy access and complete system refresh.
• Preventative maintenance on high-mileage or older vehicles with original rollers.
• To prevent costly repairs caused by belt misalignment or breakage.
• To restore smooth, quiet belt operation and consistent timing performance.
