    Good job! ROCO Air R Disassembly pics

    This is to thank AM for a little box that showed up here at my office today.

    It had a Roco Air in it and what were fresh news from Tas three weeks ago

    I'll be tinkering with it later tonight as it needs to be fixed from somewhere...

    Pics later on... I just couldn't help but posting it from excitement!

    [SIZE="3"]AM... BIG THANK YOU!!!![/SIZE]

    Well here are some pics. It's kinda old news nowadays as there is Roco Air R no more for 2008... but hey, it's its first day with me!!

    Roco_04

    Roco_08

    Roco_03

    Roco_02

    Here's the bottom out adjust thingy...

    Roco_05

    Roco_06

    From it came a seal that isn't looking good... Bad Zoke. This shock has not many miles on it...

    Roco_07

    Here's the leak that made AM to send the shock to Mexico for proper disposal...

    Roco_09

    I'll write Zoke to see if they can send me the rebuild kit (they should) and instructions for rebuilding.

    I'll take it tomorrow to a shop where they have a bench vise, 'cos I couldn't open the thing with the old tube trick to access the damaged seal.

    Is it the old Rp23 or an 08? Doesn't the 08 have some sort of BO adjust, along with the high volume air can? It's like you've been working for Fox, cause that sounds like something right down your ally.

    Either way if your about to destroy "another" air shock don't you think it's time to go back to a man's shock?... ie coil.

    We have to up it to standards of "other boards"...

    (I didn't posted some macros that are ridiculous )

    BTW... the shock's shaft is 32mm just like the forks. Actually, the wiper reminded me some of Enduroforkseals... I'm not saying they're the same, though.

    It got enhanced with a 3 position switch (low speed compression).

    Ok... this was wrenching day here.

    The VDub has new distributor, spark plugs, cables, fresh oil and a new hydraulic fluid reservoir for the power steering.

    I got to work a bit on the Roco too...

    Good news, I could open it.
    Bad news, I'll probably won't get to apply for Warranty.

    I almost broke my wrists trying to open the air canister turning it counterclockwise, like any shock.

    Wrong... It was to the other side.

    One of the "particularities" of the design is that for any air sleeve chamber work, you have to fully service the thing.

    How did I discover that?? The canister goes off by turning clockwise and it has to be extracted to the upper eyelet side. Thing is, the canister won't go away unless you remove the air valve stem and the rebound adjuster assembly... Which I did.

    Now... When I tried to put everything together, obviously the rebound assy was going nowhere. I nicked the shaft on the rebound needle and there's some detent balls under the rebound adjuster that like to fly away.

    I said to myself... "No biggie, I'll open the damper... it has a cover over what looks a valve stem"... Well, Marzocchi in their infinite wisdom and on behalf of user serviceability made this cover to have a PENTAGON drive.

    As at last... I dunno what they use for lubrication, but to me it looks like pure crap. There are damaged seals everywhere and while I admit I was no gentle opening it, I haven't been so with the "crappy" 5th Air or the Float and they have had no problems.

    Here's the guts of the Roco...

    Roco_17


    This was the state of the seals...

    Roco_10

    Roco_14

    Roco_11

    The head of the shock... Notice the design. Canister goes off counterclockwise.

    Roco_15

    The high volume air sleeve...

    Roco_16

    AM... it looks like you bottomed the shock a few times...
    (However, the bottom out o-ring should not be this bad)

    Roco_12

    The way the bottom out adjustment works if a work of genius... You open the bottom part of the air sleeve and it simply "fills" a given space at atmospheric pressure... You close it and you have a negative spring and a vacuum that will counteract the positive spring. Clever.

    I'll make my best to make this one work out, but it'll take time... The wisest thing to do was to send the shock right away to Zoke... But I'm dumb and curious like a cat. I needed to see for myself.

    Geez Warp, that's a great autopsy..........What gives with Zocci lately and there Shiate seals????? Were thier Warranty and service departments getting lonely as no one ever had problems pre06. Those were the good ole days as anyone or any shop could fix the fork on site in a day or 2 versus the crap they've been shipping lately. Kinda reminds me of the ole Manipoo/Judy days.

    Geo... send yours to service. Don't try to fix it yourself unless you make sure you have all tools and spares.

    great stuff Warp,

    always bringing us good pics and knowledge!!!

    about the pentagon drive, i donīt know why they do that... just to piss everyone off???
    i found on the net that it is used on water faucets, or water mains, but i know nothing more...
    Could you post a pic of it?

    i have the same problem with a radium shock... i already have a valve to use on the platform damping side, but i donīt know how to open the damn thing...

    anyway, good luck bringing the roco back to life!
    are you sending it to marz or buying the seals?

    Obrigado!

    Here's the pentagon drive. I've worked in the machine shop and gas turbine fields and I had never seen one. I'm not saying they don't exist, but it's not a common tool.

    Roco_

    I think I'll buy the parts and rebuild it myself... sending it over there and back will not be cheap or fast anyways. That is if Marzocchi doesn't have any more surprises inside and no more special tool are required.

    hum...thatīs the devils work, ehehe.

    the pentagon bolt on the radium is the oposite, the roco is like a hex, but the radium bolt is more like a nut. roco is recesed while on the radium, the recesed part is the outside of the hex...

    strange things we see these days... eheheh.

    keep up the good work!

    abrazo,

    Marcolino
