16mm inertia flywheel extractor

The right tool for every disassembly: 16 mm inertia flywheel puller

Removing an inertia flywheel by hand or with unsuitable tools is one of the most common mistakes in the slot workshop. A poorly applied strike, off-centre traction, or the use of pliers can damage the axle, mark the flywheel, or, in the worst case, ruin a bearing that has taken time and money to adjust. The XT-1116 puller exists precisely to avoid all that.

Function and performance

The 16 mm inertia flywheel puller applies extraction force axially and perfectly centred on the flywheel, without transmitting lateral stresses to the axle or the bearing housing. The result is a clean, controlled, and repeatable disassembly, regardless of whether the flywheel is mounted with a tight fit or has not been touched for some time.

This type of tool is especially useful when working with competition motors where the inertia flywheel plays a direct role in acceleration response and rotational inertia. Modifying, balancing, or replacing a flywheel without the proper puller risks damaging a part that may be difficult to replace.

Compatibility

Designed for inertia flywheels with a diameter of 16 mm. Always check the exact diameter of your flywheel before using this puller to confirm it matches this measurement. Using a puller of incorrect size can damage both the tool and the part.

Correct assembly and use

• Secure the motor or drivetrain on a stable surface before applying the puller.
• Position the puller centred over the flywheel, correctly aligning the claws or support of the tool.
• Apply pressure progressively and evenly, without strikes or sudden pulls.
• If the flywheel offers resistance, check for any additional fastening elements (tightening screw, loctite, etc.) before forcing.

Common mistakes

• Using a screwdriver or lever to pry: damages the axle and can bend the flywheel.
• Striking the axle from the other end: transmits direct impacts to the bearings.
• Using a puller of different size: can mark or deform the flywheel if larger, or slip if smaller.

Frequently asked questions

What is the purpose of an inertia flywheel puller?

It allows for the controlled removal of the inertia flywheel from the motor shaft by applying centred axial force. It prevents damage to the axle, flywheel, and bearings that could occur with improvised methods.

How do I know if my inertia flywheel measures 16 mm?

Measure the outer diameter of the flywheel with a caliper or vernier. If the result is 16 mm, this puller is the right one. If in doubt, consult the specifications from the motor or flywheel manufacturer.

Is it necessary to use a puller or can I do it by hand?

Technically, some flywheels with a very light fit can be removed by hand. However, in practice, most competition flywheels have a tighter fit, and removing them without the proper tool poses a real risk of damaging precision components. The puller is the correct way to do it.

Can I use this puller with any brand of slot motor?

The tool is compatible with any motor whose inertia flywheel has a diameter of 16 mm, regardless of the brand. Always verify the measurement before use.

Do I need any additional tools to use this puller?

Generally no. The puller is designed to be used independently. In some cases, it may be helpful to secure the motor with a small vice or clamp to have both hands free during extraction.

The XT-1116 16mm flywheel puller is a precision tool designed for the safe removal of 16mm inertia flywheels in slot car motors. Essential for any serious slot car workshop, it prevents damage to axles, bearings, and flywheels during disassembly. Compatible with 16mm flywheels from any brand, it ensures a clean, controlled extraction every time — a must-have for competition preparation and motor maintenance.
