Information
Power Steering Belt
This Power Steering Belt is an OE Match V-belt drive belt designed for Porsche 928 models equipped with power steering. It transfers power from the engine to the power steering pump.
Fits:
Porsche 928 1985 - 1995
for cars with power steering
Diagram ref no 20
The belt transmits rotational force from the engine to the power steering pump, enabling hydraulic pressure that assists steering. This reduces steering effort and improves control, especially at low speeds. Without a functioning belt, the power steering system will not operate correctly.
Function
• Drives the power steering pump via crankshaft pulley
• Maintains hydraulic pressure for assisted steering
• Ensures smooth and responsive steering operation
• Provides reliable power transmission under load
Over time, drive belts wear, stretch, or crack due to heat and continuous use. A worn belt can slip, reduce steering assistance, or fail completely -resulting in heavy steering and potential loss of control. Replacing the belt ensures consistent power delivery to the steering system and prevents unexpected failure.
When to replace
• Cracked, frayed, or glazed belt surface
• Squealing noise from engine bay
• Reduced or inconsistent power steering assistance
• Visible belt slack or wear
• During routine service or preventative maintenance

Manufactured to OE specifications for fit, performance and durability, this camshaft idler roller is engineered to withstand continuous operation, high rotational speeds and demanding engine conditions. It is an essential service item during timing belt replacement and preventative maintenance, helping to preserve the reliability and accuracy of the engine timing system.
What This Product Does:
- Guides and supports the camshaft timing belt.
- Maintains correct timing belt alignment and routing.
- Helps reduce belt vibration and movement.
- Promotes even belt wear and consistent operation.
- Supports accurate synchronisation between crankshaft and camshaft.
- Contributes to reliable engine timing and performance.
Symptoms Of Wear Or Failure:
- Chirping, squealing or grinding noises from the timing belt area.
- Excessive timing belt vibration.
- Rough or noisy bearing operation.
- Visible wear or damage to the roller surface.
- Timing belt misalignment.
- Uneven or accelerated timing belt wear.
- Bearing looseness or excessive play.
- Increased risk of timing belt failure.
Why Replacement Matters:
- The camshaft idler roller operates continuously while the engine is running and is subjected to constant rotational forces, heat and bearing loads. Over time, bearing wear, loss of lubrication and material fatigue can reduce the roller's effectiveness and reliability.
- A failing idler roller can negatively affect timing belt tracking and alignment, causing premature belt wear and placing additional stress on surrounding timing components. In severe cases, bearing seizure or roller failure may result in timing belt damage or loss of engine timing, potentially leading to costly engine repairs.
