help! fork spring swap

okie, i am swapping fork springs on my 12' adv.

i loosened the fork caps from the tubes, then loosened the caps from the locknut. BUT, they unthread about an inch or so then stops. it stops fairly solid, and i don't want to force it. what am i missing to remove the cap from the pushrod?

edit* i need to get from this:



to this:



i just tried again, and it stops solid when it is close to being unthreaded.

They just unscrew, there isn't any keepers or set screws. Mine came loose by hand, just a little nudge to break them loose with the wrench. I know, not helping. Maybe the threads are bunged up from a previous owner?

  • I think you forgot to turn the preload adjuster all the way out before removed the cap.

i did that. halfway through the threads on both forks was a tough spot. little more pressure, and both spun off after. it just didn't seem right at first, as i didn't want to booger it up. got them swapped, we are good.


another question though: one fork had one neoprene washer under the cap, the other had 2. any reason why one of them had 2 washers? i swapped to .58's, so i put only one washer on both.

This is pretty common with WP forks (both my 05 450 EXC and my 07 300 XC-W had the same "issue")
My understanding is that they test the springs and compensate differences in rate with washers.

This is the normal behavior for these forks, no worries:) Just force it, and it will get past that point and unscrew easily after.
