Over time, the wiper on BMW X5 E70, X6 E71, E90, E91, E92, and E93 vehicles may slow down, stick during operation, or stop moving entirely. This is often caused by wear on the plastic pinion gear teeth in the wiper motor (OEM part numbers: 61617200510, 61614848601, 61617161711). Operating a vehicle with a malfunctioning wiper poses safety risks, especially in adverse weather conditions. This replacement gear is designed for use with the original wiper motor assembly for the listed BMW models. Installation instructions: - Remove the wiper linkage assembly with the electric motor attached. - Detach the motor from the linkage. - Note the relative position of the gear lever before disassembly. (Exact positioning within 1 mm is not required; final zero-position calibration occurs after reassembly.) - Carefully remove the gear lever from the motor shaft. - Install the new gear onto the motor shaft. - Place a soft protective layer (e.g., a magazine) under the plastic gear to prevent damage during pressing. - Gently heat the gear using a hairdryer to ease installation. - Do not use excessive force or metal tools (e.g., punches) to press the lever stem—this may damage internal components. - A bench vise may be used for controlled pressing. - Perform installation at room temperature. - Apply lubricant generously—fill all available gear housing space. - Reinstall the linkage assembly and reconnect the electrical connector. - With the wiper blades removed, power on the wiper system to calibrate the zero position. - Once the motor stops at the correct rest position, install the wiper blades. Compatible models: BMW X5 E70, X6 E71, E90, E91, E92, E93 Common failure symptoms: Wiper blades stall mid-cycle, move intermittently, or stop completely. Audible motor operation indicates the motor and wiring harness are functional.
