What Is This Part?

This clutch coupling belongs to the Panamera's Porsche Doppelkupplung dual-clutch transmission. The PDK system combines two partial transmissions, each connected to the engine through its own multi-disc clutch. While one clutch transmits power through the selected gear, the next suitable gear can already be selected in the other partial transmission. Controlled engagement and disengagement of the clutches then transfers drive between the two paths during a gear change. 

What Does This Part Do?

• Transmits engine torque: Provides the frictional connection through which engine power enters the transmission. 
• Controls engagement: Works with the PDK hydraulic control system to engage or release the relevant clutch as driving conditions require. 
• Supports gear changes: Enables the transmission to transfer drive between its two preselected gear paths. 

Why Replace This Part?

Replacement may be appropriate when inspection confirms worn friction surfaces, heat damage or another mechanical defect affecting clutch engagement. Excessive slipping produces heat, and damaged friction surfaces may no longer transmit torque consistently. The cause should be established before fitting replacement components, rather than treating every engagement problem as clutch wear. 

For a Porsche Panamera PDK clutch replacement, ask a transmission specialist to assess the clutch assembly alongside its hydraulic control and operating conditions. The Panamera PDK relies on controlled clutch pressure and the correct transmission oil level, so clutch replacement should follow a confirmed diagnosis rather than symptoms alone. 

When to Replace This Part?

• Confirmed slipping: Engine speed rises without the expected increase in road speed, and testing identifies the clutch as the cause. 
• Visible heat damage: Inspection during repair reveals overheated, distorted or damaged friction surfaces. 
• Confirmed wear: Examination establishes that the clutch can no longer maintain the required torque connection. 
• Persistent engagement problems: Specialist checks identify a clutch defect after assessing the associated hydraulic control and transmission oil condition. 

Where Is This Part Fitted?

Location: Within the PDK transmission's clutch section, at the connection between the engine and the transmission input paths. It operates as part of the gearbox assembly rather than as an external gear-selection component. 

FAQs

• Does this fit every Porsche 970 Panamera? No universal fitment is stated. Use the applications above and confirm the exact part number against your vehicle's transmission specification.
• Does a shifting problem automatically mean the clutch needs replacing? No. PDK clutch operation depends on hydraulic control and correct oil conditions, which should be assessed before deciding on replacement.

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)  

Diagram Ref No 40

Located within the driver's footwell pedal assembly, this spring forms part of the mechanical clutch pedal operating and return mechanism.

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.

Symptoms Of Wear Or Failure:
The clutch pedal return spring is subjected to repeated extension and contraction every time the clutch pedal is operated.

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.

Why Replacement Matters:
Replacing a damaged clutch pedal return spring helps restore the mechanical return force designed into the original Porsche pedal assembly.

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.

The clutch coupling is essential for smooth acceleration, responsive gear changes and efficient transmission operation.

A worn or malfunctioning clutch assembly can affect how effectively power is transferred through the gearbox.

Possible symptoms include:

• Jerky or hesitant gear changes
• Juddering when pulling away
• Delayed engagement of drive or reverse
• Excessive clutch slipping
• Unusual vibration during acceleration
• Transmission warning messages
• Reduced gearbox performance

These symptoms may also result from hydraulic, electronic or other internal transmission faults and should be properly diagnosed.

Why Do PDK Clutch Couplings Fail?

PDK clutch assemblies are engineered for demanding operating conditions but can deteriorate through mechanical wear and repeated heat cycles.

Common causes include:

• Gradual wear of the clutch friction surfaces
• Excessive heat generated during repeated clutch engagement
• Incorrect transmission oil condition or servicing
• Internal hydraulic pressure problems
• Mechanical damage within the clutch assembly
• Prolonged operation with existing gearbox faults

When Should It Be Replaced?

Replacement is recommended when diagnostic testing confirms excessive clutch wear, slipping or internal mechanical damage.

A defective coupling may also require replacement during a PDK gearbox overhaul or following transmission damage.

Before replacing the assembly, the gearbox control system, oil condition and associated transmission components should be inspected to establish the cause of the fault.

Why Choose Genuine Porsche?

Genuine Porsche transmission components are manufactured to the original factory specifications for the relevant gearbox assembly.

Using the correct original clutch coupling helps preserve the intended operation of the PDK transmission, including controlled clutch engagement and smooth gear selection.

It is particularly important when repairing sophisticated Panamera GTS and E-Hybrid drivetrains.

Installation Notes

Replacement requires specialist knowledge of Porsche PDK transmissions and the appropriate workshop equipment.

The gearbox must be dismantled sufficiently to access and replace the clutch assembly.

Inspect the surrounding transmission components, seals and hydraulic systems before reassembly.

Diagram Ref No 16

Fitted at the gearbox output, this factory replacement component connects the transmission to the driveshaft, allowing driving force to reach the wheels. Its extended flange configuration is designed for the specific PDK gearbox assemblies that require the long version.

Ideal for transmission repairs, driveshaft replacement work or restoring an original gearbox assembly where the existing flange has suffered damage.

What Does It Do?

The long driveshaft flange provides the connection between the PDK transmission output and the driveshaft assembly.

The gearbox transfers engine power through its internal gearsets and differential. The driveshaft flange then provides the mechanical link that allows this rotational force to pass to the driven wheel.

Its longer configuration accommodates the mounting arrangement of the relevant transmission, ensuring the driveshaft connects at its intended position.

Why Is It Important?

The flange must provide a strong, accurately positioned connection while the drivetrain experiences constant changes in speed and load.

A correctly functioning driveshaft flange helps:

• Transfer gearbox torque to the driveshaft
• Maintain correct driveshaft mounting and positioning
• Provide a secure connection during acceleration and deceleration
• Reduce unwanted movement at the transmission output
• Support smooth and consistent drivetrain operation

A damaged flange can compromise the security of the driveshaft connection and place additional stress on surrounding components.

Why Do Driveshaft Flanges Fail?

Although manufactured for demanding operating conditions, driveshaft flanges can become damaged through mechanical wear or excessive loading.

Possible causes include:

• Worn or damaged internal splines
• Distortion of the driveshaft mounting face
• Damaged bolt holes or retaining components
• Repeated drivetrain shock loads
• Incorrect fitting or previous repair damage
• Corrosion affecting mating surfaces

When Should It Be Replaced?

Replacement should be considered when inspection identifies damaged splines, cracks, excessive play or wear around the driveshaft mounting points.

Possible symptoms of a defective flange or associated drivetrain components include:

• Clunking when engaging drive or accelerating
• Vibration that increases under load
• Excessive movement around the driveshaft connection
• Unusual knocking from the transmission output area

These symptoms may also be caused by driveshaft joints, differential components or gearbox mountings, so diagnosis is important before replacement.

Installation Notes

Inspect the transmission output splines, driveshaft connection, retaining hardware and shaft oil seals before installation.

On applicable 997.2 Carrera PDK gearboxes, this flange must be used with the specified associated retaining component. Follow the relevant Porsche technical information and tightening procedures.

Ensure the driveshaft is correctly secured and inspect the completed assembly for abnormal movement or oil leakage.
