9-tooth pinion 5.4mm in diameter

An anglewinder pinion designed to ensure that adjustment is never a problem

The Mustang M-PC002 9-tooth pinion with a diameter of 5.4 mm was created with a very clear purpose: to solve one of the most common friction points in the preparation of slot cars with motors in anglewinder configuration. Its elongated geometry allows the pinion to be moved along the motor shaft with greater usable travel, resulting in a precise fit with the crown gear without depending on how much it protrudes from the transmission assembly.

Features and function

• 9 teeth: transmission ratio aimed at rally configurations, where a balance between acceleration and top speed is sought.
• Diameter of 5.4 mm: specific dimension; always check compatibility with your motor shaft diameter before installation.
• Elongated design: the main argument of this pinion. It allows for more comfortable and precise alignment with the crown gear, gaining leeway whether the crown protrudes little or a lot.
• Anglewinder configuration: specifically designed for motors mounted at an angle to the rear axle, the most common configuration in the rally category.

Recommended applications

This pinion fits naturally into slot car preparations aimed at anglewinder rally, where the inclined motor position requires greater flexibility in adjusting the transmission train. If you build or prepare cars for this discipline, the long design of the M-PC002 saves you time and avoids compromises in pinion-crown alignment.

Installation and preparation

Before installing the pinion, check that the inner diameter (5.4 mm) matches exactly with the output shaft of your motor. A fit that is too loose generates vibration and loss of transmission; one that is excessively tight can damage the shaft. Once installed, take advantage of the extra travel offered by the elongated design to centre the pinion with respect to the crown gear and achieve the least possible play without lateral rubbing.

Common mistakes

• Not checking the shaft diameter before installation: each motor may have slightly different measurements.
• Tightening the fixing screw without having previously aligned the pinion and crown in the vertical plane: lateral play causes premature wear and noise.
• Confusing this pinion with versions of fewer teeth or different diameters: always check the reference M-PC002.

Frequently asked questions

What motor configuration is this pinion designed for?

It is designed for motors in anglewinder configuration, that is, those mounted at an angle to the rear axle of the car. This is the usual configuration in rally category cars.

What advantage does the long design offer compared to a standard pinion?

The greater axial travel allows for more leeway in adjusting the position of the pinion on the shaft, facilitating alignment with the crown gear regardless of how much it protrudes from the chassis or motor mount.

Which crown gears is it compatible with?

The provided information does not specify specific crown gear compatibilities. We recommend consulting with the manufacturer or our technical team to ensure that the module of the pinion matches that of your crown gear.

Is the diameter of 5.4 mm the diameter of the shaft or the pinion?

The diameter of 5.4 mm corresponds to the inner hole of the pinion, that is, the diameter of the motor shaft on which it is mounted. Check this measurement on your motor before placing an order.

Can I use this pinion in a sidewinder or inline configuration?

It is specifically designed for anglewinder. Although the shaft diameter may match, the geometry and length may not be optimal for other motor configurations.

The Mustang M-PC002 is a 9-tooth pinion gear with a 5.4 mm shaft diameter, engineered for anglewinder motor configurations in slot car racing, particularly rally-spec builds. Its elongated design allows fine adjustment along the motor shaft, making crown alignment straightforward regardless of crown protrusion. A practical and precise transmission component for competitive slot car preparation.
