What to do if you’re having problems building your set

If the set you’re building doesn’t look right or the parts just don’t stick together the way you expect them to, we recommend taking a step back and having another look at the building instructions. Try taking apart the last few steps and then building them again. You’ll also want to make sure all of your pieces are pressed together well.

Did you know you can download most instructions online from our service site? Having digital instructions lets you zoom in to see exactly how the parts fit together.

When building Technic models, you have to be extra careful to use the right parts. We include size charts and small illustrations on the pages themselves that show you the exact size of the pieces and cross axles you’ll need to use. You can find the Technic measurement chart here.
