For XPLOR fork caps fitted with preload adjusters, you should turn the preload adjuster with the cap when loosening from the cartridge. A KTM Special tool is available part # T14087. In my case, I designed and 3D printed a tool that works just fine. Damage to the preload adjuster thread may occur if you don't do this. If you want the stl for this tool, please leave a comment below and I will contact you.
If your XPLOR fork caps don't have preload adjusters you can just unscrew them from the cartridge rods without a special tool...
This shows you all the steps to change the fork oil seal in a WP XPLOR fork, fitted in 2020 KTM and Husqvarva offroad models. The video is long, but hopefully will help you, especially if it's the first time for you.
The required fork oil is WP SAE4.
The tool for installing the seals and the tool to set the air gap, I got them from Aliexpress.
