O.S. Engine OS29701210 Rotation Sensor Fixing Screw GT55  [OS29701210]

Rotation sensor fixing screw for GT55

This small-scale fixing screw is an OEM-branded replacement part intended for securing the rotation (RPM) sensor on GT55 model RC glow engines. It is supplied as an accessory for model engine maintenance and tuning tasks and is described here strictly as an RC-scale component.

Use this screw to hold the sensor bracket or pickup in its designed position on the engine housing. When installing, align the sensor and bracket, start the screw by hand to avoid cross-threading, and tighten carefully to seat the part without deforming nearby components. Avoid excessive torque that can strip threads or damage the sensor body.

In a tuning context the screw's role is purely mechanical: it keeps the sensor stable so RPM readings remain consistent during bench runs or track testing. A secure mounting helps reduce false triggers from vibration and supports repeatable tuning adjustments.
