Information
Cam idler roller, 46mm diameter – 28mm wide.
This is a high-quality cam-/timing-belt idler/guide roller designed to replicates the original manufacturer specifications for diameter, width, bearing quality. Cam idler roller maintaining correct belt tension and alignment so that the camshafts, crankshaft (and in balance-shaft applications) remain perfectly synchronised. If the idler becomes worn or seizes, the belt can deviate, skip teeth or fail, potentially leading to catastrophic engine damage.
Fits:
Porsche 924S 1986 - 1988
Porsche 944 1983 - 1989*
Porsche 944 S, 944 S2, 944 Turbo
Porsche 968 1992 - 1995
* see Notes 2 & 3
Note 1: Also fits early 87 924S up to engine # 43H01919 (Manual Trans) & 43H60384 (Auto Trans)
Note 2: Also fits early 87 924S from engine # 43H01920 (Manual Trans) & 43H60385 (Auto Trans)
Note 3: Early cars (83-86) that have been updated to the later style water pump with belt guard rail will use this roller.
Diagram ref no 6
• 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.

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
