pic needed fork tops quick help.. ta

[andy j]

hi guys... need to identify some forks from a 2008 - poss 2009 bike..

i have the 50mm single chambers so i know what these look like.. one nut on the top - rebound on top comp on bottom.
i have been told they have comp on the top... im thinking they are the dual chamber 50mm?? what was prior to the 50mm? 45mm mazzocchi? and when did these come on the bikes.. they are black.
I have seen the red top ones on the post with the bladder bleed but the ones i need to identifi look like they are silver.. from the not clear pic i have..

can some one post me a pic up of any to compare..

many thanks

I don't have a pic, but I know the dual chamber 50mm zokes have an outer silver cap and an inner red cap. When looking at the top of the fork, the outer cap has slots in it for a spanner wrench to loosen and remove the cartridge. The center of the outer cap has a red anodized cap with a hex nut so that you can loosen and open the cartridge. There is a bleed nipple on the outer cap. I can't remember which side is what regarding compression/rebound but it is opposite most bikes. The TXC's and TC's had these forks.

The TE's and I THINK SM's have the open chamber forks. from looking at the top of them, there is only one visible cap, and it covers the whole top. It has a hex removal nut as well. This cap is completely silver, no red at all.

Both the open chamber and the twin chamber forks have black uppers.

ok ta they are red top with the slots... so that confirms they are the dual chamber.. thanks..

The "Andy's" figured it out!!

On the 50mm dual chamber Marzocchis', that red cap on the top is the compression valve and should have a 'C' written on it .. the rebound clicker is on the bottom

Is there a video out there on taking apart the 50mm Marzocchi forks? I need to clean out the oil, replace seals and clean the everything out.
Also, do you use anything to clean out the fork tubes outside of a rag and maybe some oil?
Can you clean the valves without dissembling them i.e., a cleaner or air?

Oh and what is the difference between a open-end spanner and a open-end wrench?

Think they're one and the same?? I use adjustables but got asked in a post the other week if that means crescent wrench. Confused?

Crescent is a brand name, but most people in the US call adjustable wrenches, Crescent. It's like Kleenex to facial tissue. Everyone just calls it Kleenex.

Pumping both names in to the net shows them being the same, but in the service manual they use open-end wrench with a open-end wrench picture, and then the open-end spanner picture has what looks sort of like two rulers connected at one end. Per the manual, "Use a 21mm spanner to unscrew the compression." Bases on the use an open-end wrench should work. Not sure why they decided on "spanner" for the on and not with the other wrenches.
Unless, you're supposed to use a spanner like this, http://www.af1racing.com/store/scripts/prodView.asp?idproduct=919

It would be great if someone had a video servicing the Marzocchi.

Ah, like Hoovering..

The above thread goes into a lot of detail re stripping down Marzocchi's. Might help or these guys might have some answers for you.

Further research tells this is the spanner they are recommending. It's a pin spanner so you can disassemble the top of the cartridge, http://www.racetech.com/images/tools/220W/TMPS_1.jpg
I'm gonna make one.

Basically these seem to be comparable to a specific size spanner, but the pin spanner gives you the ability to adjust to the size needed. So you only need one tool for multiple size use instead of a set specific size open-end spanners.

 

[moto66]

Ah right, I agree, I'd make one with some cut plate and some bolts.

While that pin spanner IS the correct tool, I have been using the wrench that came with my angle grinder. It's like a U on the end of a handle and has two pins on the ends of the U. It fits good enough, and works like a champ.

A word of caution: DO NOT put a socket or a wrench on the red hex cap and loosen it UNLESS you are wanting to go through the bleed procedure for the inner chamber. If you loosen the red cap, it will introduce air into the inner chamber, which is a "air free" chamber.

There is a video showing how to bleed out the inner chamber. I think it's in one of the posts in this thread under a cafehusky link. It seems pretty straight forward and they used PVC pipe to hold the bladder instead of the specialty tool. I want to say it is a Marzocchi video from the CA shop.

Try Youtube or these guys. I know it's in a post I replied on. I can look for the video if you want.


Same shop as mentioned above, try asking them for the video link. I have had correspondence with this guy.

Yeah, the it's not an overly difficult process, but I wanted to caution against loosening that nut unless you are ready to disassemble the fork completely and go through that process.

Where's a good deal on a 50mm fork seal kit (seals and dust wipers)?

 

[andyman]

Not sure where a good deal may be, but Synergy seals makes a great Seal.

 

[Logroller]

Going straight through Marzocchi for the OEM seal kit and it's cheaper than anyone I could find. $56+shipping.

 

[Logroller]

Turns out all the shops have the wrong part numbers for the 2006 TE450 forks seals and dust seals. My forks are 50mm (the TE450/510) were revalved to the 50mm this year. Confirmed it by measuring my fork tubes and I have a Husky pamphlet that states the same. F.Y.I., when ordering parts for this year, they are listed as 45mm.

If you go straight through Marzocchi for the parts they are cheaper than Husky dealers at least for seal and boots and that's with shipping. Also, they don't use the Husky part numbers so there won't be confusion with errors.
