fork dismanteling

#1 PostAuthor: C Martin » Fri Jan 08, 2010 1:11 am

i am haveing trouble undoing the bolt in the bottom of the fork legs so i can seperate the legs from the stancions on my z650, i have tryed the broom handle trick but still wont budge, i am begining to think that somebody has put them together using threadlock, i was wondering if anybody has any other suggestions or the propper fork holding tool i could borrow. I have spent two afternoons trying to get them apart and took them to my local bike shop but they only had the tools for yamaha forks which we tryed but did not fit, thanks

Had the same problem.

Held the top of the forks in a vice - with rags to protect. Then wound the pressure up on the compressor and out they came using an airgun. Inner did not have a chace to spin.

Only problem is doing them up again. Need to find a tool of some form. May look to make something this afternoon.

The Club hold and lend out specialist Kawasaki tools.
I used the fork leg socket and returned to Jerry when finished.
Give Jerry a call.

Chris, I had same trouble with my 650 ones recently. In the end and a lot of trying, I used a large easyout on the end of a couple of long extensions and it was out in under a minute. I inspected the cylinder piston unit afterwards and does not seem to have done any damage, no marks. Jim
ps did you get m/c OK

if You have access to a heat gun or small blow torch heat the area around the bolt not too hot but for about two minutes then give the bolt a quick turn and it should come loose
it has never failed Me yet

I had the same problem when trying to overhaul the forks on my KH250 and ended up making the tool. Which I think is fairly close to a 12mm socket. This was discussed recently on here. It was mentioned before by "Pigford" about using one of those adjustable multi sockets that works by having sprung loaded pins inside.

the problem with these fork legs is the bolt fuses with the alloy
by aiming the heat at the bolt rather than the fork leg usually does the job but care is needed

i agree that metal n alloy fuse but if u concentrate heat on bolt itll expand thus making it tighter :roll:
