To further understand my forks & to confirm my adjuster assembly is functioning properly, id like to know how this works? I removed the adjuster to service the showa forks (SFF-spring) like I have many times befores before. Before removing the adjuster assembly, I backed out the rebound to the softest setting and confirmed it bottomed out. After removal and while I had only the adjuster in my hand, I adjusted the rebound setting. The needle spun and clicked, but the needle didn’t move up or down in the process. Nor did it bottom out on either end of the soft/hard limits. Is this correct? If so, how do changes in the setting actually work?

You went to far in without having something that pushes against the tip of the needle. When you do that the clicker part separate from the actual needle. Try rotating the needle by hand back out to it can connect with the clicker part again.

Only worked on WP, but should be same mechanism.

The Showa adjuster spins the rebound rod and the rebound rod spins the threaded needle up in the rebound valve post. That’s what moves in and out, not the d shaped tab on the base adjuster.

If you have lost the rebound adjuster(not really a bolt) as pictured above then you would have also lost the adjusting rod.

As mentioned, the adjuster rod also came out. But I would strongly recommend having a professional look at your fork because it is likely the damper rod is damaged

this is from some one who serviced :1 day ago. MY FORKS IVE POSTED ABOVE
"Just rebuilt a set of these today... no adjuster on the spring side it’s a blank bolt... the only adjustment on the spring side is the preload and an air bleed screw... the opposite fork has both rebound and compression adjustment.."

I think you're mistaken or weren't clear about what you were asking. What are we wrong about?

If you lost the rebound adjuster (which is on the fork with damping, #95135D) you have also lost part # 46102 in that diagram. Your damper rod (the upper part of #440718) will protrude out the bottom of the fork while riding, catches the dirt and may be bent.

If it is the spring side bolt (#92055), then there is no rebound adjuster obviously, but the rod will stick out the bottom of the fork and can get bent. You also will have a lot of contamination inside the fork and potentially wear damage depending on how long it has been missing...

Yeah, no shit. Its called the SFF for a reason...

My comments from my above post still stand. The forks are different, but both have damper rods. If either lower "bolt" is lost they will protrude out of the bottom of the lug and be damaged when riding.

Hope you get your forks figured out bud.
