Convertible Top Latch Motor Gear Repair Kit for BMW E36 E46 E64

Restore proper operation to your BMW’s retractable roof without replacing costly motor assemblies. This precision-engineered latch motor repair kit targets the single most common point of failure in these systems: the original plastic drive gear. Over time, stress fractures and stripped teeth prevent the windshield latches from releasing or engaging smoothly, often stranding owners with jammed tops or erratic motor grinding. By swapping in our reinforced replacement gears, you restore reliable torque transmission and quiet cycling for a fraction of the cost of a new actuator unit.

Designed as a direct aftermarket substitute for OEM part 67618370816, each gear is cut to tight tolerances using a durable composite of steel, brass, and heavy-duty polymer plastic. This combination delivers the hardness needed to withstand repeated load cycles while protecting the motor’s copper windings from premature wear. Compatible across multiple generations of BMW convertibles, this kit bridges the gap between temporary fixes and expensive dealership replacements, giving you predictable roof movement regardless of your local climate or driving conditions.

Benefits & Practical Tips

• Targeted cost savings: Replace only the worn internal gear instead of purchasing a complete top-locking motor assembly.
• Prevent cabin leaks: Proactively upgrade aging drivetrain components before latch misalignment allows water intrusion during rain showers.
• Service recommendation: Because the motor requires panel removal and electrical disconnects, we advise entrusting disassembly to a professional shop to preserve factory weather seals and wire routing.
