Check fitment for your specific vehicle (model, year, engine) before ordering.

What Is This Part?
This shaft is part of the mechanical drive arrangement that operates the detachable lifting roof. It works within an assembly containing guides, segments, a gear wheel and supporting fixings, helping pass movement through the mechanism when the electric drive operates. Correct engagement with the surrounding components is important for the assembly to move as intended. During repair, the shaft should therefore be inspected alongside the parts that guide, support and engage with it.

What Does This Part Do?

• Transmits movement: Forms part of the mechanical path between the roof drive and the lifting mechanism.
• Works with the drive assembly: Operates alongside the associated guides, segments and gear wheel.
• Allows component-level repair: Provides a replacement shaft when inspection identifies damage or wear to this particular component.

Why Replace This Part?
Replacement may be appropriate if the shaft is broken, distorted or worn at its engagement points. Such damage can interrupt the transfer of movement through the mechanism, even when the electric drive is working. Inspection should establish whether the shaft itself is defective rather than relying on roof behaviour alone.

A stiff, obstructed or incorrectly adjusted mechanism also needs attention during the repair. Renewing the shaft without checking the guides, gears, supports and adjustment may leave the original cause unresolved. Removal for roof mechanism work is a useful opportunity to assess its condition, but does not by itself make replacement necessary.

When to Replace This Part?

• Visible damage: Inspection reveals a break, distortion or other damage that affects operation.
• Worn engagement points: The shaft no longer engages correctly with the associated drive components.
• Incomplete or intermittent movement: The electric drive operates, but diagnosis identifies the shaft as the cause of interrupted roof movement.
• Poor seating: The shaft cannot sit correctly in the mechanism after the associated supports and components have been checked.
• Damage found during dismantling: Removal exposes wear or damage that makes the existing shaft unsuitable for refitting.

Where Is This Part Fitted?
Location: Within the driving mechanism for the electrically operated detachable lifting roof. On applicable Porsche 968 models, this is the PR:650 roof drive assembly, alongside its guides, gear wheel, segments and supports.
