Sidewinder motor mount -0.5mm offset

Fine-tune the transmission with the exact offset your Evo-6 pod needs

The SICH67 is the sidewinder motor mount with a -0.5 mm offset designed by Slot.it for its Evo-6 pod. An apparently simple component that, in the technical preparation of a competitive slot car, has a direct impact on the mesh between pinion and crown gear, the tension of the transmission, and consequently, on the mechanical efficiency of the assembly.

Function and performance

The motor mount is the part that secures the motor to the pod and determines the distance between the motor shaft and the rear axle. In a sidewinder configuration, the motor is mounted parallel to the rear axle, and any variation in that distance directly affects the backlash between pinion and crown gear.

The -0.5 mm offset shifts the motor slightly towards the rear axle compared to the standard position. This is useful when working with pinion and crown gear combinations that require a centre distance smaller than nominal, or when excessive backlash is detected in the transmission with the reference mount at 0 mm.

Compatibility

This mount is specifically designed for the Slot.it Evo-6 pod. Before installing it, it is advisable to verify that the pinion-crown gear combination you are using indeed requires this offset value, as excessive tightening between the two parts can generate heat, premature wear, and loss of performance.

Installation and preparation

• Replace the original motor mount of your Evo-6 pod with the SICH67.
• Check the backlash between pinion and crown gear after installation: there should be a minimal but perceptible play when moving the assembly manually.
• Combine it with the positive offsets from the Slot.it catalogue if you need to move away from the rear axle instead of closer.
• Always use the appropriate fixing screws and tighten to the recommended torque to avoid deforming the plastic of the pod.

Common mistakes

The most common mistake is installing an incorrect offset by not measuring the centre distance required by the chosen gear ratio beforehand. If the pinion and crown gear are too tight—without play—the motor will lose efficiency and the operating temperature will rise significantly. If they are too far apart, the transmission will slip and wear will accelerate. Taking two minutes to check the backlash before securing the motor to the track saves many problems.

Frequently asked questions

What is the difference between a -0.5 mm offset and a 0 mm offset?

The offset indicates the displacement of the motor relative to the reference position (0 mm). With -0.5 mm, the motor shaft is positioned 0.5 mm closer to the rear axle, reducing the centre distance between the pinion and crown gear. This allows for a tighter mesh when the combination of parts requires it.

Is it compatible with Slot.it pods other than the Evo-6?

According to available information, this mount is designed for the Evo-6 pod. For other pods in the Slot.it catalogue, it is advisable to consult the official compatibility chart, as the fixing geometry may differ.

How do I know what offset I need for my pinion and crown gear combination?

The most reliable way is to measure the centre distance required by your specific gear ratio and compare it with what the standard mount offers. Slot.it publishes technical documentation with reference distances for its transmission systems, which can serve as a starting point.

Can I use this mount in an inline or anglewinder configuration?

No. This mount is designed exclusively for sidewinder configurations, where the motor is mounted parallel to the rear axle. For other motor configurations, there are specific mounts with different geometries.

Does the mount come with fixing screws?

The available information does not specify whether screws are included. We recommend checking the packaging or consulting us directly before ordering if this is a critical detail for your preparation.

The Slot.it SICH67 is a sidewinder motor mount with a -0.5 mm offset, designed for the Evo-6 pod system. It allows precise adjustment of the pinion-to-crown centre distance, ensuring optimal mesh and efficient power transfer in 1/32 slot car racing. A key preparation part for competitive club racers and technical builders looking to fine-tune their drivetrain setup.
