28z Ultra-Light Aluminium Anglewinder

Precision and Lightness for Your Anglewinder Setup: 28z Aluminium Crown Gear from Sideways

The 28z Anglewinder Ultra-Light Aluminium Crown Gear (ref. SWGA1628E) from Sideways is a specific preparation component for setups with the motor angled relative to the rear axle. Made from aluminium, its main advantage is the reduction of rotating mass, a key factor in the performance of any slot car prepared for competition or demanding track use.

Features and Function

• 28 teeth in Anglewinder configuration.
• Material: ultra-light aluminium, which reduces weight in the drivetrain and improves acceleration response.
• Compatible axle diameter: 2.38 mm.
• Secured with an M2 allen screw for a firm and secure fit without damaging the axle.

Installation and Preparation

The M2 allen screw fastening system allows for precise positioning of the crown gear on the rear axle and ensures there are no play or slippage under load. For correct installation, it is important to properly align the crown gear with the pinion before tightening the screw, ensuring that the drivetrain is centred and free from lateral rubbing. A moderate tightening torque is sufficient; over-tightening can mark the axle and complicate future disassemblies.

Compatibility

This crown gear is designed for anglewinder configurations, meaning those where the motor is positioned at an angle relative to the rear axle. Always verify that the module of the crown gear matches that of the pinion used in your motor-transmission assembly to ensure proper meshing and vibration-free operation.

Common Mistakes

• Installing the crown gear without checking lateral alignment with the pinion: this causes premature wear and noise in the drivetrain.
• Confusing anglewinder configuration with sidewinder or inline: each requires its specific crown gear according to the angle and position of the motor.
• Over-tightening the M2 screw: this can deform the aluminium or mark the axle irreversibly.

Frequently Asked Questions

What is the difference between an Anglewinder crown gear and a Sidewinder crown gear?

The difference lies in the position of the motor. In an Anglewinder setup, the motor is angled relative to the rear axle, which affects the attack angle of the crown gear. In a Sidewinder setup, the motor is parallel to the rear axle. Using the incorrect crown gear can lead to poor meshing or physical incompatibility with the chassis.

Why is it important to reduce the weight of the crown gear?

By reducing the rotating mass in the drivetrain, the motor requires less energy to accelerate, and the car's response improves, especially in corner exits. In club competition prepared cars, this difference is noticeable in lap times.

Is the M2 allen screw included with the crown gear?

The manufacturer's description indicates that the fastening is done with an M2 allen screw, but it does not specify if it is included in the pack. We recommend confirming this before completing your order or having spare M2 screws in your toolbox.

What axles is this crown gear compatible with?

This crown gear is compatible with axles of 2.38 mm diameter, which is the standard size commonly found in many cars and 1/32 scale chassis.

Can I use this crown gear on a homologated competition chassis?

It depends on the regulations of each championship or club. Always check the specific rules before using aftermarket parts in a regulated category.

The Sideways SWGA1628E is a 28-tooth ultra-light aluminium anglewinder crown gear for 2.38 mm axles, secured with an M2 allen screw. Designed for slot car competition setups where reducing rotating mass is essential for faster lap times and sharper throttle response. Compatible with 1/32 scale anglewinder configurations.
