Professional Pinion Extractor - Installer 2018

Workshop precision in every adjustment: the professional pinion extractor-installer from Slot.it

Working with pinions by hand or using inadequate tools is one of the most common causes of damage to axles, bearings, and gears. The SITL01 from Slot.it is the professional answer to this problem: a tool specifically designed to extract and install pinions with the correct force and direction, without impacts, twists, or risk of deformation.

One tool, two essential functions

The SITL01 integrates the two most repeated operations in the preparation of a slot car into a single tool: extracting the pinion from the axle and placing it in the desired position. Both actions are performed in a controlled manner, applying the right pressure and on the correct axle, which eliminates lateral loads that can damage bearings or slightly bend the axle.

Why it makes a difference in tuning

• Prevents damage to the axle when extracting tightly fitted pinions.
• Allows for the pinion to be placed in the exact position in a repeatable manner.
• Reduces the risk of pinion deformation during assembly.
• Speeds up gear ratio changes during tuning or competition sessions.
• Professional design from Slot.it, a benchmark brand in slot car tools and mechanics for Sport track.

Ideal for…

This tool is designed for both the club racer fine-tuning their car between heats and the preparer working on multiple references each week. If you frequently change gear ratios — seeking the balance between top speed and acceleration according to the layout — the SITL01 saves you time and protects your components with every operation.

Aspects to consider

Always check the compatibility of the tool with the diameter of the axle and pinion you are working on. Slot.it markets it as a professional tool for use with its own pinions and axles, although its design can adapt to other components of similar dimensions. If in doubt, consult the technical documentation from Slot.it or contact us.

Frequently asked questions

What exactly is this tool for?

It serves two operations: extracting a pinion that is stuck on the axle without damaging it, and placing a new pinion in the correct position by applying pressure in a controlled and aligned manner.

Is it compatible with pinions and axles from other brands?

It is designed for Slot.it components, but it may work with equivalent parts from other brands. We recommend checking the dimensions before using it with third-party components.

Why should the pinion not be extracted with pliers or screwdrivers?

Using inappropriate tools applies lateral or point forces that can bend the axle, scratch the pinion, or damage nearby bearings. A specific tool like the SITL01 applies the correct axial force uniformly.

Can it be used with pinions of different tooth counts?

The number of teeth does not affect extraction or placement, as the tool acts on the inner diameter of the pinion and the axle. What matters is that the diameter of the pinion hole and the axle are compatible with the tool.

Is it useful only for competition or also for recreational use?

It is useful for any enthusiast who makes pinion changes with some frequency. Whether you compete in a club or simply prepare your car at home, it protects your components and makes the process much more comfortable and safe.

The Slot.it SITL01 professional pinion extractor and installer tool is an essential workshop accessory for slot car enthusiasts and competitive racers. Designed to remove and fit pinions precisely without damaging axles or bearings, it is compatible with Slot.it Sport track system components and equivalent parts. A must-have for any serious slot car preparation bench.
