Manufactured to OE specifications for fit, function and durability, this cam idler roller is engineered to withstand high rotational speeds, engine heat and continuous operating loads. It is a recommended replacement during timing belt servicing, engine maintenance and timing system overhauls.
What This Product Does:
- Guides and supports the timing belt during engine operation.
- Maintains correct belt alignment throughout the timing system.
- Helps reduce belt vibration and unwanted movement.
- Promotes even timing belt wear.
- Supports accurate camshaft and crankshaft synchronisation.
- Contributes to reliable engine timing and smooth performance.
Symptoms Of Wear Or Failure:
- Squealing, chirping or grinding noises from the timing belt area.
- Excessive timing belt vibration.
- Rough or noisy bearing operation.
- Timing belt misalignment.
- Uneven or accelerated timing belt wear.
- Visible wear or damage to the roller surface.
- Bearing play or looseness.
- Increased risk of timing belt failure.
Why Replacement Matters:
- The cam idler roller operates continuously whenever the engine is running and is subjected to constant rotational forces, temperature fluctuations and bearing loads. Over time, the internal bearing can wear, lubrication can degrade and the roller surface may become damaged.
- A failing idler roller can compromise timing belt alignment, leading to increased belt wear and unnecessary stress on the timing system. In severe cases, bearing seizure or roller failure may result in timing belt damage or loss of engine timing, potentially causing expensive engine repairs.

Information
Alternator belt, Belt size: 9.5 x 725.
The Genuine Porsche 99919209750 alternator belt is an OE V-belt for selected Porsche 911 1974–1979 models. It drives the alternator and cooling fan, helping maintain battery charging and essential air-cooled engine cooling. Ideal for routine servicing or replacing a cracked, slipping, noisy or worn original belt.
Fits:
Porsche 911 Turbo/SC 1974 - 1979 (Please choose by size)
Diagram ref no 12
This belt is used on selected classic Porsche 911 models and fits the alternator / cooling fan pulley system.
What This Part Does / Functions
• Drives the alternator from the engine pulley system
• Helps keep the battery charged while the engine is running
• Drives the engine cooling fan on air-cooled Porsche 911 models
• Supports correct engine cooling airflow
• Helps maintain stable electrical system performance
• Provides correct OE Porsche belt fitment for the listed pulley setup
• Replaces a worn, cracked, stretched, glazed or noisy belt
• Helps prevent belt slip, squeal and charging/cooling issues.
Why Replace This Part?
The alternator belt is a critical service item on air-cooled Porsche 911 models because it drives both the alternator and the cooling fan. Over time, the belt can crack, glaze, stretch, fray or lose grip on the pulleys. A worn or slipping belt can cause charging problems and may reduce cooling fan speed, which can lead to engine temperature concerns. Replacing the belt with a Genuine Porsche OE alternator belt helps restore correct belt drive, reliable battery charging and proper cooling fan operation.
When to Replace This Part
• If the belt is cracked, glazed, frayed or visibly worn
• If the belt squeals or slips during engine operation
• If the battery or charging warning light appears
• If the belt tension can no longer be set correctly
• During scheduled service or preventative maintenance
• When replacing alternator, fan pulley, shims or related belt-drive hardware
• If the belt has been contaminated by oil, fuel or debris
• When recommissioning a stored classic Porsche 911.
Where It Fits on the Car
This belt fits on the rear engine alternator / cooling fan pulley system. It runs between the crankshaft pulley and the fan/alternator pulley assembly, driving the alternator and cooling fan.
