1. Remove the wheel from the bike and remove cassette if fitted.
2. Pull the drive side end cap from the axle – no tools are required.
3. With the freehub body, this simply slides off the axle. The H_Ratchet SGL is likely to stay in place within the hub body. Should it come out, please note the orientation in preparation for re-installing.
   
4. To service the freehub mechanism, clean the H_Ratchet SGL and ratchet rings of the freehub body with a dry micro-fibre cloth and lubricate with a thin layer of lightweight grease on each surface.
   
5. Fit the H_Ratchet SGL onto the drive side of the axle, with the sprung side facing outwards. Then slide the freehub of your choice on. You may have to turn the H_Ratchet SGL a little to slide into the ratchet ring teeth. 
6. Push the adaptor/end cap back on to the drive side of the axle. Please Note: if swapping from SRAM XD or SHIMANO HG to SHIMANO Microspline  or vice versa the drive side end cap is specific to the freehub body. 
7. Ensure that the adaptors/end caps are fully pressed home to ensure proper fit and prevent any lateral play.
   Please Note: Remove the elastic band before fitting your cassette
