A400 Explor Unico Hammer Spring Replacement

I have read multiple threads on replacing A400 Hammer springs, but the Hammer spring and the Hammer spring retainer are different on the A400 Explor Unico that I have. Does anyone know of a DIY on how to replace the hammer spring on the A400 Explor Unico?
