You will need to retain the original metal central pinion from the broken factory plastic gear being replaced.
The angle of the teeth are from left to right on the LEFT gear and right to left on the RIGHT gear.

The plastic drive gears are a sacrificial component within the roof drive mechanism, transmitting power from the electric motor to the roof transmission. Over years of operation, the original gears can wear, crack or strip their teeth, causing the roof to operate unevenly or stop functioning altogether. Replacing these gears restores smooth power transfer, helping the roof mechanism operate quietly and efficiently once again.

Ideal for preventative maintenance or repairing a faulty roof motor, these OE Match replacement gears provide factory-quality fitment, dependable durability and excellent value.

What Do the Convertible Top Motor Drive Gears Do?

The plastic drive gears transfer rotational power from the electric roof motor to the convertible roof transmission mechanism.

Their primary functions include:

• Transmitting drive from the roof motor.
• Operating the convertible roof mechanism.
• Ensuring smooth and synchronised roof movement.
• Reducing shock loads within the drive system.
• Helping protect more expensive drivetrain components.
• Supporting reliable opening and closing of the roof.
• Maintaining consistent roof motor performance.

As sacrificial components, the gears are designed to wear before more costly components suffer damage.

Why Replace the Convertible Top Motor Drive Gears?

The roof motor gears are subjected to repeated loading every time the convertible roof is operated.

Common reasons for replacement include:

• Worn gear teeth.
• Cracked plastic gears.
• Stripped drive teeth.
• Roof motor slipping.
• Intermittent roof operation.
• Roof motor running without moving the roof.
• Preventative maintenance.
• Roof refurbishment or motor overhaul.

Replacing worn gears restores the efficiency of the roof motor and can often eliminate the need to replace the complete motor assembly.

Symptoms of Worn or Damaged Roof Motor Gears

Common warning signs include:

• Convertible roof stops during operation.
• Roof motor can be heard running without movement.
• Clicking or grinding noises from the motor.
• Uneven roof operation.
• Roof opens or closes slowly.
• Roof fails to complete its cycle.
• Jerky roof movement.
• Visible damage to the original plastic gears during inspection.

Replacing worn gears promptly can help prevent unnecessary strain on the roof motor and transmission assemblies.

Benefits

• Restores reliable convertible roof operation.
• Eliminates worn or stripped drive gears.
• Helps avoid replacing the complete roof motor.
• Smooth, quiet power transmission.
• Factory-quality fitment.
• Long-lasting, wear-resistant construction.
• Cost-effective repair solution.
• Excellent value OE Match replacement.

Installation Recommendations

For the best results, inspect the complete roof drive system during installation, including:

• Convertible roof drive motor.
• Roof transmission gearboxes.
• Flexible drive cables.
• Roof linkages.
• Pivot points.
• Microswitches.
• Roof control module.
• Roof mounting hardware.

Clean old grease from the gearbox housing and apply a high-quality lubricant suitable for plastic gears during assembly. After installation, ensure the roof mechanism is correctly synchronised and fully tested through several complete operating cycles.
