Information
Timing camshaft belt (cam belt)
The Genuine Porsche 94410515704 timing camshaft belt is an OE toothed cam belt for selected Porsche 924S and 944 models. It synchronises the camshaft and crankshaft, maintains correct engine timing and is a critical service component. Ideal for scheduled timing belt replacement, engine service or recommissioning a stored Porsche 924S / 944.
Fits:
Porsche 924S 1986 - 1988
Porsche 944 1982 - 1991 (V8)
Porsche 944 Turbo
Diagram Ref No 5.
This belt is used on selected Porsche 924S and 944 four-cylinder engines and is a critical component of the engine timing system.
What This Part Does / Functions
• Synchronises camshaft and crankshaft rotation
• Ensures correct valve timing during engine operation
• Controls when the intake and exhaust valves open and close
• Helps maintain smooth running and engine performance
• Supports correct combustion timing and engine efficiency
• Provides OE Porsche belt fitment and tooth profile
• Replaces a worn, aged, cracked or contaminated timing belt
• Helps prevent timing-related engine damage when replaced at the correct service interval.
Why Replace This Part?
The camshaft timing belt is a critical service item. Over time, the belt can age, crack, stretch, wear or become contaminated by oil or coolant. If the belt slips or fails, the camshaft and crankshaft can move out of sync, which may cause serious engine damage. Replacing the timing belt with a Genuine Porsche OE cam belt helps maintain correct engine timing and supports reliable operation of the classic Porsche 924S / 944 engine. It is strongly recommended to inspect or replace related tensioners, rollers, balance shaft belt and water pump components during timing belt service.
When to Replace This Part
• During scheduled timing belt service
• If the belt is cracked, worn, frayed or glazed
• If the belt has been contaminated by oil, coolant or debris
• If the timing belt age or mileage is unknown
• When recommissioning a stored Porsche 924S or 944
• During camshaft, front engine seal, tensioner or roller replacement
• When replacing the balance shaft belt or water pump
• If timing belt noise, tracking issues or tension problems are present.
Where It Fits on the Car
This belt fits on the front of the engine, within the camshaft timing belt system. It runs between the crankshaft and camshaft timing pulleys and is protected by the timing belt covers.

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.
