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 waterpump with belt guard rail will use this roller.

Snap a timing belt on this type of motor and the valves stop opening and closing, but those pistons keep slamming up and down. Bent valves, broken lifters, even a broken camshaft could be the outcome! Keep the relationship between your pistons and valves civil by performing proper timing and balance shaft belt maintenance. Due to the complexity and options, please choose all of the parts that apply to your vehicle carefully.

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.

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.

It is designed to match the original-style fitment and function. This replacement timing belt helps synchronise camshaft operation, supporting correct valve timing, smooth engine running, and reliable engine performance.

Fits:
Porsche 944 S/S2 1987 - 1991
Porsche 968 1992 - 1996

Diagram Ref No 4

The cam belt forms part of the engine timing system and helps keep the camshaft movement synchronised with engine operation. Correct camshaft timing is essential for smooth running, power delivery, fuel efficiency, and long-term engine reliability.

Functions
Replaces the cam belt / timing belt
  Supports correct camshaft timing
  Helps synchronise valve train operation
  Maintains smooth and reliable engine running
  Replaces cracked, worn, stretched, contaminated, or aged belts
  Suitable for scheduled timing belt service and preventative maintenance
  OE Match replacement for Porsche 944 S / S2 and 968 engine timing service.

Why Replace This Part?
Cam belts wear with age, mileage, heat, oil contamination, tension changes, and repeated engine use. A worn or overdue cam belt can crack, fray, stretch, lose teeth, or fail without warning. Timing belt failure can cause poor running, loss of valve timing, non-start issues, or serious engine damage. Replacing the belt at the correct service interval helps protect the engine and maintain reliable performance.

When to Replace This Part
  The timing belt service interval is due
  The cam belt is cracked, frayed, glazed, contaminated, or worn
  Belt teeth are damaged or missing
  The belt has been exposed to oil, coolant, or dirt
  Timing belt tension is incorrect or unstable
  Tensioners, rollers, water pump, or front engine seals are being replaced
  Preventative replacement is being carried out during major engine service.

Where it fits on the car
This cam belt fits within the engine timing belt / camshaft drive system on Porsche 944 S, 944 S2, and 968 models. It runs around the relevant camshaft and timing pulleys according to the factory timing layout.

About Belts / Tensioners / Rollers

Engine Rebuild Belts, Tensioners & Rollers – Precision Timing for Reliable Porsche Performance

Engine rebuild belts, tensioners, and rollers are essential components in maintaining your Porsche’s precise engine timing and smooth operation. These parts work together to synchronise the camshaft and crankshaft, ensuring valves open and close at exactly the right time for optimal combustion. Over time, these components can wear or deteriorate, especially under high performance or extended use, making replacement vital during an engine rebuild or major service.

At Design911, we supply a full range of genuine and high-quality belts, tensioners, and rollers for various Porsche models including, 911, Boxster, Cayman, Cayenne, Macan, and Panamera models. Each component is designed for strength, accuracy, and long-lasting reliability — ensuring your rebuilt Porsche engine performs flawlessly mile after mile.

What Do Engine Belts, Tensioners & Rollers Do?

These components form the heart of the engine’s timing and auxiliary systems. They:

  • Drive key engine components, including the camshaft, alternator, and water pump.
  • Maintain accurate timing for optimal combustion and efficiency.
  • Reduce friction and noise through smooth roller and tensioner operation.
  • Ensure consistent belt tension to prevent slippage or premature wear.

Together, they guarantee your Porsche’s engine runs smoothly, efficiently, and reliably — whether cruising or driving at peak performance.

Why Do Belts, Tensioners & Rollers Fail?

Exposure to high temperatures, vibration, and constant motion causes natural wear over time. Common causes of failure include:

  • Aging rubber belts becoming brittle or cracked.
  • Worn bearings in rollers or tensioners leading to noise or vibration.
  • Loss of tension causing belt slippage or timing misalignment.
  • Contamination from oil or coolant degrading materials.
  • Extended maintenance intervals leading to unexpected failure.

Symptoms of failing components include squealing noises, poor engine performance, rough idle, or even timing belt failure, which can cause severe engine damage if ignored.

Why Replace Belts, Tensioners & Rollers During an Engine Rebuild?

Replacing these components during an engine rebuild ensures long-term reliability and eliminates the risk of future timing-related failures. A fresh set of belts, rollers, and tensioners restores precision, efficiency, and performance — protecting your investment.

Benefits of replacement include:

  • Restored precise timing and smooth operation.
  • Reduced risk of catastrophic engine failure.
  • Enhanced reliability and longevity of the rebuild.
  • Quieter, more efficient engine performance.

All components available from Design911 are made using premium-grade materials, precision bearings, and advanced heat-resistant compounds, ensuring maximum durability and performance in high-stress Porsche engines.
