Sidewinder motor mount 0.75mm offset

Millimetric adjustment, tangible difference: Sidewinder motor mount with 0.75 mm offset

In competitive slot racing, details make the difference between a car that tracks accurately and one that loses time in corners. The Sidewinder Motor Mount 0.75 mm offset (SICH68) allows lateral displacement of the motor in Sidewinder configuration by one-tenth of a millimetre beyond the standard, modifying the relationship between the pinion and crown gear to achieve a cleaner mesh and more efficient transmission.

Main features

• Sidewinder configuration: the motor is mounted parallel to the rear axle, allowing the crown gear to be lowered to the chassis and reducing the overall centre of gravity.
• 0.75 mm offset: precise lateral displacement that allows adjustment of the pinion-crown gear mesh depth without modifying other parts of the drivetrain.
• Reference SICH68: compatible with Slot.it mounts that require this specific offset measurement.

What changes with a different offset?

The offset of the motor mount determines the distance of the motor shaft from the rear axle. Varying it directly affects the mesh between the pinion and crown gear: an improperly adjusted offset can cause excessive play, noise, power loss, or premature wear of the teeth. Using the correct offset — in this case, 0.75 mm — ensures that the transmission operates at its optimal point, with the minimum necessary play for smooth and efficient rotation.

Recommended applications

This motor mount is designed for tuners and club racers working with Slot.it chassis who seek to fine-tune their drivetrain geometry to the maximum. It is especially useful when combined with fine pitch crowns and pinions, where control of the mesh is critical for the overall performance of the car.

Installation and preparation

The installation follows the usual procedure for Sidewinder mounts: it is fixed to the chassis at the corresponding points and the lateral play of the pinion over the crown gear is checked with the rear axle already mounted. We recommend checking the mesh by manually rotating the assembly before proceeding to track testing, ensuring that there is neither tension nor excessive play.

Frequently asked questions

What is the difference between a Sidewinder mount and an Inline mount?

In the Sidewinder configuration, the motor is mounted parallel to the rear axle (transverse to the chassis), while in the Inline configuration, the motor is perpendicular to the rear axle, in line with the car. Each arrangement has different implications for the centre of gravity and drivetrain geometry.

What exactly is the purpose of the offset in a motor mount?

The offset laterally displaces the motor shaft relative to the rear axle, modifying the mesh depth between the pinion and crown gear. An appropriate offset allows for a clean, quiet, and efficient mesh, reducing wear and improving power transmission.

Is this mount compatible with any Slot.it chassis?

The SICH68 mount is designed for the standard anchor points of Slot.it chassis in Sidewinder configuration. We recommend checking compatibility with your specific chassis model before installation, as the Slot.it range is extensive and some models may require specific variants.

Can I combine this mount with motors from other brands?

As long as the motor has housing measurements compatible with the mount's accommodation (usually the Slot.it standard can), the combination is viable. The important thing is that the offset is correct for the diameter of your pinion and crown gear.

How do I know if the 0.75 mm offset is suitable for my setup?

It depends on the combination of pinion, crown gear, and chassis you are using. If when mounting the standard mount you notice that the mesh has too much play or too much tension, switching to a slightly different offset — like this 0.75 mm — can resolve the issue without needing to modify other parts.

The Slot.it SICH68 Sidewinder motor mount with 0.75 mm offset is an essential tuning component for competitive slot car racing. Designed for Sidewinder motor configurations, it allows precise adjustment of the pinion-to-crown mesh, ensuring smooth and efficient power transmission. Compatible with Slot.it chassis and standard can motors, this motor mount is a key part for club racers and serious hobbyists looking to fine-tune their drivetrain geometry for optimal on-track performance.
