Always have done maintanance and small repairs by my own.
At the small bikes i installed the BBKs by my own. But had never removed and disassambled a fork, only changed fork oil and springs in the past.
But, i would'nt have been able to do the cartridge change to the Andreani by my own. Maybe right leg, this one was much easier than the left one, because it also had a cartdridge which was fixed with a screw from the bottom. But left leg was really strange and hard to disassemble.
Reassambling was quite easy, except of the missing tool.
I attached 2 pictures, 1 of the original fork entrails (right picture) and 1 of an Andreani fork (left picture, but not exactly the HS821 Andreani fork), where the red arrow points to the nut, which has to be countered the top cap so that this cannot loosen during driving.
unfortunatly the picture is not from our HS Andreani cartridge, because on that the nut is inside a black tube, which is between cap and spring, as on the original fork. so, you have to press down the black tube against the power of the spring until under the nut, fix it under the nut and then thighten the nut against the top cap thing.
on the picture of the original fork entrails the red arrow on the left leg points to a bushing (dont know how is it named in english, dictionary brings me 15 different words for my german one
), which is screwed in in the orignal fork so that you really do not see, that it is screwed in. you only see inside a shim with holes which has to be removed but do not see in the first moment, how to remove it.
when i am at home i can make a picture of our workaround-tool we made to compress the tube+spring, if wanted.
