technical help required

I have a gsxr1000k3, im taking the yokes off and have hit a problem. Ive got everything undone and the top bolt is off, there are 2 round nuts on the stem with key ways cut in to them. I thought it needed a C spanner which ive been having trouble finding so i went to suzuki who said it required a specific socket. Has any one done this before and do i need a suzuki part or is there another way of getting them off? Ive tried a punch and hammer to tap it round but the key ways just deform.
Thanks
Barry

Castellated nuts

Aprilia use them on RS50 swing arms. One trick is to make your own tool by grinding down a socket to leave 4 pegs which locate in the holes.

The trouble you have is

the two nuts will be locked together. You'll need to Loosen the top one from the bottom one. What you need is at least one thin C Spanner to hold the bottom nut still whilst you tap the top nut anti-clockwise with hammer and punch to loosen it. Two thin C spanners is the way to go really though. As with all jobs, having the right tools makes all the difference.


If you try at turn the two nuts together without unlocking them from each other,  you may damage the threads on the steering stem.

Just found this again

As shown in the video, you may have a lockwasher between the adjuster nut (bottom nut) and lock nut (top). So check first before trying to loosen them.

Yep...

As Richnotrich says... They will free up but ou gotta do them separately.. It's exactly the same as my K1 750, I had it all off before..

Secure the bottom one and tap the top one round... I used a heavy screw driver and it worked fine.. The prob you have is just that it's probably not been touched for 10 years so coat in WD and give it some shit mate!!

:wink:
