Pressure pinion Ø 7 x Z13 STEEL

More transmission combinations with the Sloting Plus steel pinion Ø 7 mm Z13

The SP084213 pinion is a steel component manufactured by Sloting Plus specifically for offset mounts between 0.5 and 1 mm, a very common configuration in both club preparations and competition cars. Its outer diameter of 7 mm and 13 teeth open up a range of gear ratios that are not always achievable with standard-sized pinions, making it a very useful tuning tool when looking to adjust top speed or torque on specific track sections.

Technical specifications

• Outer diameter: 7 mm
• Number of teeth (Z): 13
• Thickness: 3.5 mm
• Weight: 0.68 g
• Fixing system: press-fit on 2 mm diameter motor shaft
• Material: steel

Function and performance

As a press-fit pinion, it does not require any additional securing elements: it fits directly onto the 2 mm motor shaft. The steel ensures a wear resistance far superior to that of plastic and sufficient compared to aluminium in intensive use situations, making it suitable for both long running sessions and regular club competition.

The 7 mm diameter with 13 teeth allows for intermediate combinations with crowns of different sizes, especially in those setups where smaller pinions are too aggressive in acceleration or larger ones sacrifice too much top speed.

Compatibility

Designed for offset mounts of 0.5 to 1 mm from any slot brand. Compatible with 2 mm diameter motor shafts. Always check the centre distance of your mount before combining pinion and crown to ensure proper meshing.

Assembly and preparation

Before pressing the pinion, apply a small amount of lubricant inside the hole. Although steel is more durable than aluminium at this point, lubrication facilitates the pressing, protects the shaft, and prevents unnecessary stress on the part. Once mounted, ensure that the pinion is aligned with the crown and apply a light layer of specific gear grease: it improves performance, reduces noise, and extends the lifespan of the assembly.

Common mistakes

• Pressing without lubrication: although steel withstands better than aluminium, lubricant always facilitates the process and protects the shaft.
• Not checking alignment: a misaligned pinion generates vibrations, uneven wear, and loss of performance.
• Forgetting to grease: dry gears wear out quickly and generate more heat in the motor.
• Choosing the pinion-crown combination without measuring the mount: always check the centre distance to ensure clean meshing.

Frequently asked questions

What type of mounts can I use this pinion with?

It is designed for offset mounts between 0.5 and 1 mm from any slot brand. It is compatible with any setup that uses a 2 mm diameter motor shaft.

Do I need any special tools to press the pinion?

It is recommended to use a pinion press to apply pressure evenly and avoid damaging the shaft or the pinion itself. Pressing freehand without a guide can leave the pinion misaligned.

Do I have to grease the pinion even though it is made of steel?

Yes. All gears, regardless of material, need a small amount of grease to reduce friction, heat, and wear. Steel is more durable, but it is not exempt from wear if it operates dry.

What is the difference between a steel pinion and an aluminium one?

Steel offers greater hardness and wear resistance, while aluminium is lighter. For regular competition or long sessions, steel is usually the more durable choice. Aluminium requires more care in pressing and mandatory internal lubrication to avoid breakage.

What crowns does a Z13 of Ø 7 mm pair well with?

It depends on the centre distance of your mount and the diameter of the crown. The specific combination needs to be calculated according to the desired gear ratio and the geometry of the setup. Check the compatibility tables from Sloting Plus or seek advice from your trusted tuner.
