Rotation Sensor Mount Screw (GT55) O.S. Engine OS29701210  [OS29701210]

Rotation sensor mount screw for GT55 engines

This small fixing screw is supplied as an OEM replacement to secure the rotation (RPM) sensor on GT55 RC glow engines. It is provided as an accessory for maintenance and tuning and is identified here as a component for scale model engines.

Use the screw to clamp the sensor bracket or pickup in the intended location on the engine housing. When fitting, align the sensor, begin threading the screw by hand to avoid cross-threading, and tighten progressively until seated without distorting nearby parts. Do not over-tighten as this can damage threads or the sensor assembly.

For tuning work the screw performs a simple but important task: it keeps the pickup stable so RPM measurements remain consistent during bench testing or track evaluation. A secure mount reduces false triggers from vibration and supports repeatable tuning setups.
