Installing new wheels

The parts you need to assemble one wheel are shown below. You will need to prepare 6 wheels for the X axis.

First, fit both the tyres together.

 

 

Insert the bearing adjuster from one side.

 

 

In your wheel kit you will have a small packet of blue loctite. Dip your M5 torx screw so the end part of the threads (or upto four end threads) are covered with loctite as shown in the image.

 

 

Insert your M5 torx screw to the assembly.

 

 

And fix it to the Z Head wheel plate.
