    Before removing the forks to change the fork seals, it is best to loosen the cap on top. On these forks that requires a special tool, a large octagonal wrench. These can be bought for about $30 but I was convinced that I could design a tool that could be 3D printed. After a couple of iterations and several hours of printing, the tool in the pic worked a treat! Both caps are now loose and the forks are ready to be removed.
