Ceriani slider question

Has anyone removed the damper rod holder from the bottom of a Ceriani slider, the Marzocchi ones just drop out with a bit of a tap but the Ceriani ones are stuck fast and I can't see an easy way to get the damper rod holder out without doing damage. Any Ideas!

Thanks Crispin
 
Just the old crud holding it in place Crispin.

Perhaps a little temperature might soften it enough for the holder to drop out.  Or insert a longer rod of the exact holder ID and wiggle around, should pop straight out.

Crispin, there was a thread on this a while ago. My suggestion then was to screw the 6mm screw from the bottom of the fork back in, then back it off a couple of turns. Push the slider up as high as it will go up the stanchion then give the screw a tap with a hammer (using an 3/8'' Allen tool to transfer the shock). That should be enough to break crud-generated adhesion between the damper rod and the bottom of the slider. Maybe back off the screw another 1-2 turns and tap again until the screw bottoms to be sure.

Yep, piece of round steel rod same diameter as head of allen bolt in bottom of the slider, back it out 1/2 to 1 turn and smack it using the rod to reach it. do it a couple of times and it shoulf fall apart.
 
I understood Crispin had removed the damper rod, it was the little alloy collar stuck inside at the bottom of the slider he had issues with...

That's correct Piet, sliders have nothing in them, just the damper rod collar, which I want to get rid of. I'll get some rod same diameter as the damper rod and see if I can wiggle them loose.

Cheers Crispin
 
Soak them in a bucket of paraffin or similar for a day to soften or loosen the crud holding thecollars in place.
They may just fall out then.
That's what I had to do with one pair of recalcitrant sliders one time.
 
I used an M8 stud from a Land Rover 200 tdi water pump, then gave it a tap with a plastic mallet. Easy. It also aids reassembly.

I thought I would update this thread for completeness sake.

After trying to wiggle the damper rod holding sleeve out with no luck it became clear the Ceriani slider is very different to the Marzocchi and the damper holding sleeve is an integral part of a larger part which holds the axle and is pressed into the slider.

So to be clear you can't simply remove the damper rod holding sleeve from the bottom of a Ceriani slider the same as you can with a Marzocchi. Why you would want to is a different story, which i'll touch on in a later post.

Attached is picture of the slider with bottom section of the pressed out
second picture shows the guts of the bottom section where the damper rod holding sleeve has already been machine off

Looks like something tricky is going inside these sliders ..... this'll be interesting!
 
Crispin, I knew the bottom section of Ceriani sliders was pressed in, but I've never seen anybody take one completely apart before. Was it hard (much force needed?)? I'm guessing you're going to be putting some sort of cartridge in there, I'll be interested to see that, but how are you planning to reattach the bottom bit when you reassemble it? Loctite or something else?

Hey Ken, it's a decent interference fit and also has an o-ring, you can see the recess for it just above the axle hole. I'll just press it back in being careful to get it aligned properly, no loctite required it's not going to drop out the bottom with the axle in place. I will be fitting a cartridge, something I've been meaning to do for a long time, all the parts are machined up ready to go.

Hi crispin - will be doing a cartridge conversion on my 850 soon - I didn't know the inserts were easily removable either - you learn something new all the time! - be interested to see a few photos of conversion when you're ready - regards - Phil
 
Hi Crispin - They are not ceriani forks - they're "CEROCCHIS" - or "MARZIANIS" Marzo stanchions and innards and Ceriani sliders - i guess it wont make any difference to conversion though! - Regards - Phil
 
Hi Phil,
You're right it doesn't make a difference to the setup, but I have new Ceriani  stanchions I'll be using so have the top nut machined up for them. Reality is the conversion would be easier with the Marzocchi sliders and I'm doing a set of those as well.

Cheers Crispin
