# How to Guide: Replace Z Belt

If your Z-belt is broken or needs replacing, here is a guide on how to swap out the belt.

\
1\. One side of the x-rods will be glued to the sliders, one side will not.\
Hold the slider in one hand, and the x-rack in the other.

2\. While holding the slider and X Rack, gently pull apart from each other.\
Please be careful as to not bend the Z Rods, only a small gap is needed.

3\. Rotate the slider so the pegs point upwards. The X Axis is now free from the sliders.

4\. Take the print head and begin to slide it off the x-rack towards the end that is free to\
remove from rack.\
Set print head aside.

remove the lid (see picture below for technique)

6\. With the lid removed, you will see the z-belt running around the four pulleys on each\
threaded rod in the corners. Take a hook tool to grab the belt and slip it up and over the\
plastic base of the printer.
