10-tooth pinion 6mm in diameter

Transmission set with the long 10-tooth pinion and 6 mm for anglewinder

The Mustang M-PC003 is a long-tooth transmission pinion, with 10 teeth and 6 mm inner diameter, designed to fit all types of motors mounted in anglewinder configuration. A small component in size but crucial for the car's behaviour on the track.

Main features

• Number of teeth: 10
• Shaft diameter: 6 mm
• Type: Long pinion
• Configuration: Anglewinder
• Reference: M-PC003
• Brand: Mustang

Function and performance

The long pinion offers a greater contact area with the crown gear, resulting in smoother transmission and less traction loss. In anglewinder configurations —where the motor is positioned at an angle to the rear axle— choosing the correct pinion is essential for achieving clean and efficient engagement. With 10 teeth, this pinion is aimed at shorter gear ratios, favouring acceleration on circuits with many curves or in rally formats.

Recommended applications

Specifically designed for rally and speed, it fits any motor that accepts a 6 mm shaft in anglewinder layout. It is a viable option for both club competition setups and custom builds by enthusiasts looking to adjust the gear ratio to their circuit and driving style.

Installation and preparation

Before installing the pinion, it is advisable to check the alignment with the chosen crown gear and ensure that the fit on the shaft is secure but not forced. A light lubrication on the teeth helps prolong the lifespan of the transmission. Checking the play between pinion and crown gear is an essential preliminary step to achieve maximum performance without premature wear.

Common mistakes

• Installing a pinion with a different pitch than the crown gear: the engagement will not be correct even if it fits physically.
• Over-tightening the fixing screw on the shaft, which can deform the pinion and cause vibrations.
• Using this pinion in sidewinder or inline configurations without checking compatibility with the rest of the drivetrain.

Frequently asked questions

Is this pinion compatible with any crown gear?

It depends on the module (pitch) of the crown gear. It is essential that the pinion and crown share the same module to ensure correct engagement. Check the specifications of your crown gear before combining them.

Why is the long pinion used in anglewinder?

In the anglewinder configuration, the motor shaft is not perfectly parallel to the rear axle, which can create uneven contact with the crown gear. The long pinion increases the engagement surface and partially compensates for that geometry, achieving a more stable transmission.

What gear ratio does a 10-tooth pinion offer?

The gear ratio also depends on the number of teeth of the crown gear. A 10-tooth pinion combined with a crown gear of, for example, 30 teeth gives a ratio of 3:1. The higher that ratio, the greater the acceleration but lower top speed.

Is it suitable for club competition?

Yes, as long as your championship regulations do not restrict the use of a 10-tooth pinion. It is specifically designed for rally and speed, making it well-suited for categories that allow free choice of transmission.

Do I need special tools to install it?

A precision screwdriver or an Allen key of the appropriate size for the fixing screw is sufficient. A pinion puller makes the task easier if you need to remove it without damaging the shaft.

The Mustang M-PC003 is a 10-tooth long pinion gear with a 6 mm shaft diameter, purpose-built for anglewinder motor configurations in slot car racing. Suitable for rally and speed disciplines, it ensures smooth power transmission and reliable engagement with the crown gear. A key upgrade for any slot car builder looking to fine-tune their drivetrain setup.
