Description

A supply pack rather than a model

This is not a model to copy; it is a service pack. It supplies spare or extra pieces for educational building kits that call for tracks and sprockets. That means there is no instruction for a finished vehicle and no minifigure. If you are planning a tracked vehicle, a crane or a conveyor, you will find the basic drive components here. The parts are meant for classroom use, yet they work just as well in private Technic projects at home.

Two shapes, lots of repeats

The parts list is unusually short. The 110 pieces are divided between just two distinct elements, namely track links and sprocket wheels. Colours are limited to dark bluish grey and black, exactly the shades you would expect from Technic drivetrains. That makes counting easy and checking for completeness even easier. This page shows how the 110 pieces are shared between the two shapes, which is useful if you are planning a longer track run and need to know how much you have.

Designing your own track drive

A track drive needs two things above all: enough links for the length you want and suitable wheels to guide and drive the chain. This pack supplies the raw material, and the structure around it is up to you. That makes it a good exercise for Technic newcomers, since ideas can be tested quickly. Depending on how long you make the track, you could end up with a tank chassis, a conveyor belt or a small tracked off-road vehicle.

Other uses for the pieces

Use the “What can I build?” tool on this page to see which models you can put together from these parts combined with the rest of your collection. Because the pack contains only two shapes, it is worth thinking about the axles, beams and gears you probably own already and how they might complement the tracks. The parts list also helps when you look for replacements, in case a few links of a chain go missing. For wearing parts, that saves a lot of time.
