How to remove compression adjuster from fork bottom?

[Pete.]

Anyone know how these things are removed usually?
I got a bit happy with the throttle and stood the bike up vertical. Had to get out of it pretty sharpish and it came down with so much force it blew the adjuster clean out of the fork leg. Now I have to make a new adjuster but to do that I need to get the other one out so I can copy it but I don't know how they are removed (without the use of extreme hydraulic pressure).

Anyone know the answer?

Looks exactly the same as my GSX1400.

Towards the top of the photo you can see a section which comes in from the side of the fork ... this is usually a pressed in collar with a spring and a ball bearing sitting behind it, with the bearing pressed against the adjuster to provide the 'click' as you turn it.

I had to drill the collar on my forks and then make a new one out of a bit of brass.

All the best ... Barry

You might be able to put the short end of an allen key down the adjuster hole and insert it into the collar hole ... if you can then you might be able to push the collar out and reuse it.

You still have the problem of sourcing a new spring/ball bearing!

All the best ... Barry

Cheers Barry

I've managed to pull the collar out and also extracted the one from the good fork releasing the adjuster. They are un-damaged so I can re-use them but I need a new bearing ball as that one was blown out with the adjuster.
I'll follow-up with a how-to so that others can benefit.

Ok, so here's how it's done:

First, centre-punch and drill the back of the detent spring holder with a drill of 3.2-3.5mm. This will release the spring and ball.

Now tap the steel holder for M4

Make an extractor using a M4 bolt, a washer and a short piece of tube (a hollow dowel in this case) and pull the tube out of the leg bottom.

Now the adjuster is free to be wound out of the leg bottom.

The thread on the adjuster is M12 x 1mm by the way.

Excellent ... glad my posts made sense to you.

Even better, pics to show everyone how to take it apart

All the best ... Barry

Today's mission - Make one of these suckers...

All done.

Cut basic shape, then moved to metric lathe to cut the thread. Test-fit then cut the detent grooves. Finally put a slot in the end for adjustment.

Just got to make new detent ball sockets.

Somebody has a lot of toys and knows how to use them ... very impressive

I managed to pick up a Naerok lathe ... working great until some metal chips got into the motor (chip guard missing)!

The induction motor was making quite a humming noise ... so stripped, cleaned and all put back together ... runs without humming noise now, but gets extremely hot after 30 seconds

Looks like I need a new motor

All the best ... Barry

The Naerok 9x18 is quite handy given it's light weight and small size. A bonus is that they do metric and imperial threads which neither of my lathes can do. I had to machine this part on one lathe and cut the thread on another.

Your skills are insane. Seriously gifted there! Nice work.

Do you know how amazing that is to us meer mortals. The fact you can go "I need to make this complicated shape out of metal" then, bish bash bosh done. 99% of us on here would have been looking for S/H forks. I'll always be in awe for that ability.

I'd have definitely gone for a new fork leg, I've seen you fabricate magical tools to fix things that need one off tools but this is another level.
