Return Spring, For Right Hand Drive (RHD). Porsche 911 / 930 Turbo › 91142330601

Return Spring, For Right Hand Drive (RHD). 
The Porsche Clutch Pedal Return Spring is a replacement tension spring designed for selected right-hand-drive Porsche 911 and 911 Turbo (930) models.

Fits:

• Porsche 911 1974-1976 2.7L
• Porsche 911 1975-1977 3.0L Turbo (930)
• Porsche 911 1978-1988 3.3L Turbo (930)  

The clutch pedal is connected to a series of mechanical components that transfer the driver's input to the clutch release system. These components include the pedal shaft, clutch cable, operating levers, bushes and return springs.

The return spring maintains the appropriate tension within the pedal mechanism and helps the clutch pedal return towards its normal resting position when the driver releases it.

Correct operation is important for smooth pedal movement, predictable clutch engagement and consistent pedal feel.

Over time, the original spring may weaken, become corroded, lose tension or break due to repeated operation and age-related deterioration.

A damaged return spring can affect the clutch pedal's return action, contribute to excessive free movement or create an inconsistent pedal feel.

In some cases, the clutch pedal may return slowly or fail to settle correctly against its intended stop.

Replacing a worn or broken spring with the correct Porsche specification restores the intended spring assistance within the clutch pedal assembly.

The 91142330601 spring is documented in Porsche's right-hand-drive pedal assembly diagrams and is particularly associated with the classic 911 Turbo (930).

It is important to distinguish this spring from the alternative 91142330602, which is specified for various right-hand-drive 911 Carrera and 911 SC applications.

The two references should not be assumed interchangeable.

Suitable for clutch pedal servicing, pedal box restoration and repairs to the original clutch operating mechanism, the Porsche 91142330601 Return Spring helps maintain the correct operation of the vehicle's manual clutch pedal system.

What This Product Does:
The clutch pedal return spring provides mechanical tension within the clutch pedal assembly.

When the driver depresses the clutch pedal, the pedal mechanism moves through its operating range, transferring force to the clutch release mechanism through the cable-operated system.

As the pedal moves, the spring changes its extension and tension.

When the driver releases the pedal, the spring contributes to returning the mechanism towards its normal resting position.

The spring also helps maintain the intended relationship between the pedal, shaft, operating linkage and pedal stop.

Its main functions include:

• Assisting clutch pedal return: Helps the pedal move back towards its normal position after use.
• Maintaining spring tension: Provides the specified mechanical force within the pedal assembly.
• Supporting consistent pedal movement: Helps maintain predictable operation throughout the pedal travel.
• Reducing excessive free movement: Contributes to the correct positioning of the pedal mechanism.
• Supporting clutch operation: Works with the clutch cable and release linkage.
• Maintaining pedal feel: Helps preserve consistent resistance and return characteristics.
• Supporting correct pedal rest position: Assists the pedal mechanism in returning to its designed position.
• Maintaining original Porsche pedal operation: Provides the correct spring arrangement for the applicable RHD assembly.

Over many years, continuous use, corrosion and mechanical stress may cause deterioration.

Common symptoms of a worn, weakened or broken spring include:

• Slow clutch pedal return: The pedal may return more slowly than normal after being released.
• Clutch pedal not returning fully: The pedal may fail to settle correctly against its normal rest position.
• Reduced pedal return force: The return action may feel noticeably weaker.
• Unusual clutch pedal feel: The pedal may feel inconsistent during operation.
• Excessive pedal free movement: Loss of spring tension may contribute to an abnormal amount of movement.
• Loose or floppy clutch pedal: A broken or disconnected spring may reduce the pedal's normal resistance.
• Intermittent return action: The pedal may return differently from one operation to the next.
• Unusual noises from the pedal box: A damaged spring or loose attachment may create clicking or rattling noises.
• Visible corrosion: Rust may weaken the spring and its attachment points.
• Broken spring coils: A fractured section may prevent the spring from working correctly.
• Damaged spring hooks: Wear or breakage at either end can allow the spring to detach.
• Spring distortion: An overstretched spring may no longer provide the intended force.
• Incorrect spring positioning: A displaced spring may interfere with normal pedal operation.
• Clutch pedal sticking: A defective spring may contribute to poor return, although other faults are often responsible.
• Inconsistent clutch engagement feel: Changes in the pedal's return action may affect the driver's perception of clutch engagement.

Even though the spring is a relatively small component, its operation contributes to the feel and functionality of the manual clutch system.

1. Restore Correct Clutch Pedal Return

A weakened or broken spring may reduce the force available to return the pedal.

Installing the correct replacement spring helps restore its intended return assistance.

2. Maintain Consistent Pedal Feel

Correct spring tension contributes to predictable pedal movement and a consistent operating feel.

This is particularly important in classic Porsche models with mechanically operated clutch systems.

3. Reduce Unwanted Pedal Movement

A spring that has lost tension may allow unwanted looseness or movement within the pedal mechanism.

Replacement helps restore the correct spring force.

4. Support Reliable Clutch Operation

The spring works alongside the pedal shaft, clutch cable and release linkage.

Maintaining the correct spring arrangement supports reliable operation of these components.

5. Replace Ageing Components

Classic Porsche 911 and 930 vehicles are now several decades old.

Original pedal springs may have experienced substantial use and exposure to moisture.

Replacement is sensible when corrosion, loss of tension or fatigue damage is discovered.

6. Address Broken or Detached Springs

If the original spring has fractured or its retaining hook has broken, the pedal mechanism may no longer operate as intended.

Replacing the spring restores the correct component arrangement.

7. Complement Pedal Box Restoration

During pedal assembly refurbishment, it is good practice to inspect springs, bushes, shafts, pedal stops and associated fasteners.

Replacing a worn spring at the same time can help avoid repeated dismantling.

8. Preserve Original Porsche Mechanical Operation

Using the correct specification spring helps maintain the original design and operating characteristics of the classic Porsche clutch pedal assembly.
