Marzocchi XC500 ETA

sl51xjh

Everyone.
Just got a set of Marzocchi XC500 and got them on the bik over the weekend. Got a shock pump (halfords range) for the air chamber, but have noticed that the inlet on the forks doesn't match the coupling I have. The coupling on the pump looks like a standard schrader valve but the fork has a very small (and thin) nipple which won't fit the pump.

Anyone know of any adaptors out there for this purpose which will allow the pump to work with the fork?

Have been for a few light runs and haven't noticed bottom out and the ETA works fine so must be some air in there and the forks are smashing as an upgrade on the Dart 2's I had. Any ideas???

Oh and by the way...the Marzocchi user guide is total pants. Had read this on forums before, but it is true.

One for Halfords I think! Some older forks used a needle valve. Most pumps come with the shrader fitting.

you will need the Marzocchi valve adaptor that should have come with the forks.

You only need the adaptor on the left side (eta side) on my 600 eta and never really need to adjust it tbh. The other side is a normal standard schrader valve which is used to set the sag.

Guys.

Thanks for this...what I have one the letf hand fork (viewed from ride position) is the rebound adjust...are you saying I can pop that off and find the air valve in there. I haven't tried that as yet as it seems quite well on. I think the XC500 is a coil on that side and an air chamber on the other, but I could be wrong...maybe its the other way round.

On the right hand fork there is the little red ETA slider thing. That comes off quite easily and has the small nipple valve inside. I had assumed this was the air chamber, but it could be the spring.

Like I say, the user manual is total garbage and doesn't even have this sort of simple explanantion in it...OMG :shock:

Never got anything by way of valves/adaptors etc with the fork. Should I go back to seller and ask them why not????

is the adaptor that you need and they come with all Marz aftermarket forks as New. if you bought an OE fork then you might not get it.

and What year is the fork. So we dont have to go through all the latest manuals to get the right one!

2008 year fork ETA and air preload on the right leg and the left leg is rebound adjust on the bottom of the leg.

but that is from the manual.

Pics of the tops abd bottoms of your fork legs would be good.

Cheers again.
Fork is 2008 Marzocchi XC500 ETA as per above link...although not purchased here, but from UK Bike Store...and as far as I am aware, brand new out of the box and not OE. However, no user manual or any other stuff was in the box upon opening so downloaded from link on same webpage. If I was due to get an adaptor for the forks then I need to speak to the guys I got it from and get this sent out.

Nicklouse...where did you find the manuals you speak of and are they the same as mine. As you describe the air preload is in the right leg under the ETA and the left leg has a rebound adjust on the top (have prised this off and no air valve underneath). Not sure about the bottom but can check for rebound control. Don't recall seeing anything there when I was putting them on.

Hope this helps.

The ETA side has the spring in it and an air chamber that uses that funny adaptor. As I said you shouldn't need to adjust that side its the top of the other side that sets the preload and will have the schrader valve on it.
Thats if its anything like mine. Try unsrewing that top cap on the left leg.

Here's the manuals

Windwave will do the adaptor, probably this one although no pic. Call them they are very helpful in my experience

Number 1.

The ETA side does have the funny valve. The other side does have the rebound but I prised the rebound cap off and there was nothing underneath it and certainly no valve capable of fitting my shock pump.

The manuals link you gave me is the one I found, but it doesn't really tell you very much at all...apart from about twenty ways to make sure your wheel is aligned correctly. :?

Are you sure the top of rebound leg is where the shock pump attachs? I don't doubt you I'm just confused as to what I have bought if you have the same forks with different geometry and attachments.

Only going by what mine is like tbh. I've just checked the instructions for yours and they haven't improved since I got mine lol.
Might there a valve on the bottom of the right leg? Seems strange that you would have to take that adaptor with you all the time.
