Guide Bushing + Screw for metal chassis

Guide bush and screw BRM for metal chassis: the adjustment that makes the difference

When preparing a metal chassis in 1/32 scale, every detail matters. The Guide Bush + Screw BRM-S013H is the original spare part from BRM designed to securely fix the guide on metal construction chassis, ensuring that the car transmits steering forces effectively and maintains stable contact with the rail.

Function and performance

The bush acts as an intermediary element between the guide and the chassis, absorbing some of the play and ensuring that the guide pivots with controlled freedom without excessive movement. The screw included in the pack secures the assembly with the appropriate tightness for metal chassis, which have different tolerances compared to plastic or resin chassis.

A worn bush or an out-of-spec screw can cause the guide to move laterally, the car to deviate from its trajectory, or the braids to lose contact with the rail in corners. Replacing it when excessive play is noticed is one of the basic maintenance operations in any preparation workshop.

Compatibility

This spare part is specifically designed for BRM metal chassis in 1/32 scale. If you have doubts about whether your specific model uses this bush, consult the assembly manual of your chassis or check the reference on the official BRM website before placing your order.

Assembly and preparation

• Remove the guide from the chassis by loosening the original screw before extracting the bush.
• Check the condition of the housing in the chassis: if there is deformation or burr, correct it before installing the new bush.
• Insert the bush gently; it should not require excessive force.
• Tighten the screw firmly but without overdoing it: in metal chassis, excessive tightening can damage the threading.
• Verify that the guide pivots freely after assembly and that there is no noticeable lateral play.

Common mistakes

• Using screws from another reference: the metrics may seem compatible but can create play or damage the chassis thread.
• Not checking the bush during periodic maintenance: it is a wear part that should be inspected after each intense running session.
• Over-tightening: it can lock the guide pivot and worsen rail tracking.

Frequently asked questions

Is this bush suitable for BRM plastic chassis?

Not necessarily. This spare part is intended for metal chassis. Plastic chassis may require a different reference. Check the breakdown of your specific model to ensure.

When should I replace the guide bush?

When you notice that the guide has excessive lateral play, that the car moves imprecisely on the rail, or that the original screw no longer tightens properly. It is a common wear part in chassis that accumulate many hours of running.

Is the screw included in the pack?

Yes, the reference BRM-S013H includes both the bush and the screw.

What type of rail is this assembly compatible with?

Compatibility with the rail depends on the guide you use, not the bush itself. This component is solely responsible for securing the guide to the BRM metal chassis.
