Product Information
Product Information
Wiper motor mount plate.
OE Match wiper motor mounting plate, supplied in primer finish, designed for early Porsche 356 models produced between 1952 and 1957. This plate provides the correct mounting surface and alignment for the wiper motor within the front body structure.

Fits:
Porsche 356 1952 - 1957 Coupe / Cabrio

Diagram ref no 9

The mount plate secures the wiper motor to the body, maintaining correct motor positioning and alignment with the wiper transmission. Proper mounting ensures smooth, consistent wiper operation and prevents vibration, misalignment, or premature wear of the motor and linkage.

Function:  Installed behind the front body panel, the wiper motor mount plate provides a rigid, stable base for the motor assembly. It absorbs operational loads and vibration while maintaining precise alignment of the motor shaft and linkage arms. Correct plate geometry is essential to ensure proper sweep motion and reliable long-term operation of the wiper system.

Original wiper motor mount plates on early Porsche 356 models are prone to rust, fatigue, or distortion due to age, moisture ingress, and prolonged vibration. A weakened or misaligned mounting plate can cause wiper motor noise, poor wiper sweep, or mechanical strain on the linkage system. Replacing it with an OE Match plate restores structural integrity, correct alignment, and reliable wiper performance.

When to replace:
•  Original plate shows corrosion or metal fatigue
•  Wiper motor mounting points are loose or distorted
•  During full body restoration or front panel repair
•  When upgrading or replacing the wiper motor assembly
•  Preventive replacement on unrestored vehicles

About Wiper Mechanism

Wiper mechanisms are essential components that ensure smooth, consistent windscreen wiping in your Porsche. Working in tandem with the wiper motor, the mechanism (also called the wiper linkage or transmission) converts the motor’s rotary motion into the sweeping movement of the wiper arms.

At Design911, we offer a complete range of genuine and high-quality aftermarket wiper mechanisms for all Porsche models - including 911, Boxster, Cayman, Cayenne, Macan, and Panamera. Each assembly is precision-engineered for perfect fitment, reliable motion, and long-lasting performance, whether you’re restoring a classic or maintaining a modern Porsche.

What Do Wiper Mechanisms Do?
The wiper mechanism connects the wiper motor to the wiper arms, transferring the motor’s torque through a system of linkages, joints, and pivots. This ensures the blades sweep across the windscreen at the correct angle and pressure, effectively clearing rain, dirt, and debris.

A properly functioning mechanism guarantees:

  • Smooth, synchronized wiper movement.
  • Correct blade positioning for maximum visibility.
  • Quiet, vibration-free operation.

Why Do Wiper Mechanisms Fail?
Over time, wiper mechanisms can suffer from mechanical wear or corrosion due to constant movement and exposure to the elements. Common failure causes include:

  • Worn joints or bushings: Causing excess play or uneven motion.
  • Corroded linkages: Leading to stiffness or total seizure.
  • Broken pivot arms or connecting rods: Often due to frozen wipers or excessive load.
  • Poor lubrication: Accelerating wear of metal components.

Signs of a failing wiper mechanism include uneven wiping, one arm not moving, noisy operation, or total failure of the wiper system.

Why Replace Faulty Wiper Mechanisms?
A damaged or worn wiper mechanism compromises safety by reducing visibility, especially in heavy rain. Replacing the mechanism ensures:

  • Reliable, smooth wiper function.
  • Clear and streak-free windscreen visibility.
  • Prevention of further damage to the wiper motor.
  • Compliance with MOT safety standards.

Design911 offers both genuine Porsche and premium aftermarket wiper mechanisms, ensuring perfect compatibility, precision movement, and OEM-level reliability. Every replacement part is designed to deliver durable performance and restore your Porsche’s wipers to factory operation.
