26z angled crown gear

26-tooth anglewinder crown gear, the part that precisely closes the transmission of your slot car

The 26z angle crown (ref. AV20652) from Avant Slot is manufactured for anglewinder setups, where the motor operates at an angle to the rear axle. In this type of configuration, the gear ratio and the quality of the crown gear are crucial for both acceleration response and smoothness at sustained speed.

Technical specifications

• Number of teeth: 26z
• Diameter: 16 mm
• Compatible axle diameter: 2.38 mm
• Mounting: M2 screw (included in the pack)
• Mounting type: anglewinder configurations
• Brand: Avant Slot
• Reference: AV20652

Function and performance

In an anglewinder transmission, the crown gear operates at an angle to the motor pinion, allowing for a lower centre of gravity for the assembly and freeing up space in the chassis. With 26 teeth and a diameter of 16 mm, this crown gear offers a moderate gear ratio, suitable for both fast sections of track and technical layouts where control and precision on corner exit are sought.

The M2 screw anchoring system —included— ensures a firm grip on the 2.38 mm axle, preventing the crown gear from slipping under load and facilitating adjustment or replacement without the need for special tools.

Installation and preparation

The installation process is straightforward: insert the crown gear onto the axle to the desired position and tighten the M2 screw with an appropriately sized Allen key. Before installation, it is advisable to ensure that the axle is clean and free of burrs to guarantee the perpendicularity of the crown gear and avoid vibrations during operation. A small amount of low-resistance threadlock on the screw can be helpful in cars that regularly compete on abrasive surfaces.

Compatibility

This crown gear is designed for 2.38 mm axles in anglewinder configurations. It is important to confirm that the motor pinion it is paired with is also of the anglewinder type and that the module of both parts matches to ensure proper engagement without play or interference.

Common mistakes

• Combining this crown gear with a pinion of a different module: the engagement will be poor and cause premature wear.
• Not checking the crown-pinion alignment before closing the chassis, which can lead to noise and power loss.
• Over-tightening the M2 screw on aluminium or plastic axles, which can damage the axle. Adjust firmly but without forcing.

Frequently asked questions

Is this crown gear suitable for inline or sidewinder setups?

No. The angle crown is specifically designed for anglewinder configurations, where the motor is positioned at an angle to the rear axle. Inline or sidewinder setups require straight crown gears with different tooth profiles.

What pinion should I use with this 26-tooth crown gear?

It depends on the gear ratio you are looking for your track. The key is that the pinion is compatible with the module of this crown gear. Check the specifications of the pinion before combining them and verify the engagement before the first run.

Is the M2 screw included?

Yes, the M2 anchoring screw is included with the crown gear, so you do not need to purchase it separately.

Can I use this crown gear with axles of a different diameter?

It is not recommended. The crown gear is designed for a 2.38 mm axle. Using it with a different diameter would compromise the anchoring and concentricity, directly affecting track performance.

Is it suitable for club racing?

Yes, as long as the championship regulations allow the module and the resulting gear ratio. It is a commonly used replacement part in club setups due to its reliability and ease of replacement.

The Avant Slot AV20652 is a 26-tooth anglewinder crown gear for 2.38 mm axles, featuring a 16 mm diameter and M2 grub screw included. Designed for anglewinder slot car setups, it delivers reliable power transmission and straightforward installation, making it a go-to replacement part for club racers and hobbyists working with Avant Slot chassis and compatible 1/32 slot car configurations.
