Steel pinion 13z 7.5mm

Steel Pinion for Anglewinder: 13 Teeth, 7.5 mm Pitch

When preparing a slot car with an anglewinder configuration, the quality of the transmission makes the difference between a setup that endures races and one that fails at the most inconvenient moment. This 13-tooth steel pinion with a 7.5 mm pitch from MB (ref. MB-08013) is designed precisely for that: to provide a precise, durable transmission with the correct meshing for this type of setup.

Main Features

• Material: steel, for greater durability compared to plastic or nylon pinions.
• Number of Teeth: 13z.
• Pitch: 7.5 mm, specific for anglewinder transmissions.
• Reference: MB-08013.
• Brand: MB.

Function and Performance

The pinion is the link in the transmission that connects the motor shaft to the crown gear. In an anglewinder configuration, the motor is mounted at an angle relative to the rear axle, which requires components with the correct geometry to ensure clean meshing without play. Using steel instead of softer materials reduces progressive wear and maintains meshing precision for longer, which is especially relevant in prolonged practice sessions or club competition.

With 13 teeth, this pinion allows you to adjust the gear ratio by combining it with different crown gears according to the circuit's needs: more top speed on fast layouts or more acceleration on technical circuits with many curves.

Compatibility and Installation

This pinion is designed for anglewinder transmissions with a 7.5 mm pitch. Always check that the inner diameter of the pinion is compatible with your motor shaft before installation. A correct fit prevents vibrations, noise, and premature wear of both the pinion and the crown gear.

For optimal installation, ensure that the alignment between the pinion and crown gear is perfect: a slight lateral deviation can generate unnecessary friction and reduce performance. Using a specific alignment tool greatly facilitates this process.

Common Mistakes

• Installing the pinion without checking the alignment with the crown gear, leading to asymmetric wear.
• Using a pinion with the wrong pitch: always check that the pitch of the pinion and crown gear match.
• Not securing the pinion properly to the motor shaft, causing play and loss of traction.

Frequently Asked Questions

Is this pinion compatible with any anglewinder configuration?

It is compatible with anglewinder transmissions with a 7.5 mm pitch. For other configurations (sidewinder or inline) or different pitches, you will need a pinion with the corresponding specifications.

What advantage does steel have over nylon in a pinion?

Steel offers greater wear resistance and maintains dimensional precision over time. Nylon may be quieter, but it wears out faster, especially under intensive use or competition.

Which crown gears can I combine with this pinion?

With any 7.5 mm pitch crown gear compatible with anglewinder configuration. The combination of pinion/crown gear teeth determines the gear ratio: the greater the number of teeth on the crown gear relative to the pinion, the more torque and acceleration; the smaller the difference, the more top speed.

How do I know if the pinion is properly installed?

Turn the assembly by hand before testing on track. The meshing should be smooth, without hard spots or excessive play. If you notice noise or irregular resistance, check the alignment and tightness.
