Manufactured from high-strength steel with a precision-wound inner cable and a durable, flexible outer sheath, the cable is engineered to resist wear, vibration and corrosion while maintaining smooth operation over its full 2750mm length. It provides factory-style fitment and is ideal for restoring accurate vehicle speed readings during repairs or restoration projects.

What This Product Does:

• Transmits rotational drive from the gearbox to the mechanical speedometer.
• Provides accurate vehicle speed readings.
• Includes both the inner cable and outer protective casing.
• Ensures smooth, low-friction operation of the speedometer.
• Maintains reliable communication between the transmission and instrument cluster.
• Helps preserve accurate mileage recording on mechanical systems.
• Restores factory-style operation of the speedometer.
• Forms an essential part of the vehicle's mechanical speedometer system.

Symptoms Of Wear Or Failure:

• Speedometer needle fluctuating or bouncing.
• Complete loss of speedometer operation.
• Clicking, squealing or whining noises behind the dashboard.
• Intermittent speed readings.
• Stiff or seized cable movement.
• Broken inner drive cable.
• Damaged or split outer cable casing.
• Inaccurate vehicle speed indication.
• Odometer failing to record mileage correctly (where mechanically driven).
• Visible corrosion or wear on the cable assembly.

Why Replacement Matters:

• The speedometer cable operates continuously while the vehicle is moving and is subjected to constant rotation, vibration and environmental exposure. Over time, the inner cable can wear, stretch or break, while the outer casing may crack or allow moisture and dirt to enter, increasing friction and accelerating wear.
• A faulty speedometer cable can lead to inaccurate speed readings, erratic needle movement or complete loss of speedometer and odometer function. This can affect driver awareness, vehicle legality and the accuracy of recorded mileage.
• Replacing the complete inner and outer cable assembly restores smooth, accurate speedometer operation and dependable performance. The OE Match replacement provides factory-correct length, precise fitment and durable construction, helping preserve the authenticity, functionality and driving experience of your classic Porsche.

The speedometer cable forms the vital mechanical connection between the transmission and the speedometer gauge, transmitting rotational movement to accurately display vehicle speed and record mileage. Over time, original cables can become worn, stretched or seized, resulting in inaccurate readings, fluctuating needles or complete speedometer failure.

Manufactured to OE specifications, this OE Match replacement restores reliable operation while maintaining the authentic mechanical speedometer system found on early air-cooled Porsche 911 models.

What Does the Speedometer Cable Do?

The speedometer cable transfers rotational movement from the transmission drive to the speedometer head, allowing the instrument to accurately display vehicle speed and operate the odometer.

Its functions include:

• Transmitting drive from the gearbox to the speedometer.
• Providing accurate vehicle speed readings.
• Operating the odometer and trip counter.
• Ensuring smooth speedometer needle movement.
• Supporting reliable instrument operation.
• Maintaining original factory mechanical speedometer functionality.

A correctly functioning speedometer cable is essential for safe driving and accurate vehicle mileage recording.

Why Replace the Speedometer Cable?

After decades of continuous use, the internal cable and outer casing can suffer from wear, corrosion and lack of lubrication.

Replacement is recommended if the cable shows signs of:

• Fraying or broken inner cable.
• Stiff or seized operation.
• Excessive wear. Kinked outer casing.
  
• Corrosion. Damaged end fittings.
  
• Noisy operation.
• Inaccurate speedometer readings.

Replacing a worn cable restores dependable speedometer performance while helping to protect the speedometer head from unnecessary wear.

Symptoms of a Worn or Failing Speedometer Cable

Common symptoms include:

• Speedometer needle bouncing or fluctuating.
• Complete loss of speedometer function.
• Squealing or clicking noises behind the dashboard.
• Inaccurate speed readings.
• Odometer not recording mileage correctly.
• Intermittent speedometer operation.
• Excessive vibration in the speedometer needle.

Replacing the cable at the first signs of wear helps prevent damage to the speedometer mechanism and ensures continued accuracy.

Benefits

Installing this OE Match Speedometer Cable Input Shaft provides:

• Restores accurate speedometer readings.
• Ensures smooth needle movement.
• Maintains correct odometer operation.
• Eliminates speedometer cable noise.
• Protects the speedometer head from excessive wear.
• Factory-quality fit and finish.
• Reliable long-term performance.
• Perfect for concours restorations and everyday driving.

Installation Recommendations

Professional installation is recommended, particularly during gearbox or instrument refurbishment.

While replacing the speedometer cable, it is advisable to inspect:

• Speedometer drive gear.
• Transmission drive fitting.
• Speedometer head.
• Dashboard instrument seals.
• Cable routing clips.
• Rubber grommets.
• Instrument illumination and wiring.

Ensure the cable is routed correctly with smooth bends and free from sharp kinks to maximise service life and maintain accurate operation.

Speedometer reset knob
The OE Match speedometer reset knob is a replacement interior control used to reset the trip odometer on the speedometer in classic Porsche 911 models from 1965 to 1977. This small dashboard component allows the driver to manually reset the trip counter to zero for tracking distance during journeys. Please note Original Porsche part is no longer available.
Sold individually

Fits:
Porsche 911 1965 - 1977

Diagram ref no 3

The speedometer reset knob is a small knurled adjustment knob located on or near the speedometer gauge in early Porsche 911 dashboards. It connects to the trip odometer mechanism and allows the driver to manually reset the distance counter.

The OE Match Speedometer reset knob is designed to replicate the original Porsche component in appearance, size and fitment. It is particularly useful because the original Porsche part is no longer available, making OE-style replacements an important solution for maintenance and restoration of classic models.

The knob allows the driver to reset the trip odometer (day trip counter) to zero. This feature helps drivers track individual journey distances, fuel consumption or maintenance intervals.

Replacing a worn or missing reset knob restores full functionality to the instrument cluster and ensures the trip counter can be operated easily and reliably.

Function
• Trip Odometer Reset: Allows manual reset of the speedometer trip counter
• Instrument Control: Connects to the internal odometer reset mechanism
• Driver Convenience: Enables tracking of trip distance and mileage
• Restoration Fit: OE-style design maintains authentic interior appearance

Over time the small reset knob can become worn, cracked or lost during instrument servicing. Without the knob, the trip odometer cannot be reset easily. Installing a new OE Match replacement restores full functionality of the speedometer system and preserves the authentic interior appearance of classic Porsche models.

Consider replacing the reset knob if you notice:
•  Missing or broken speedometer reset knob
•  Difficulty resetting the trip odometer
•  Worn or damaged instrument control
•  During dashboard or instrument cluster restoration
