Marzocchi 48 Service Parts (NA)

[twowheels]

As good as the Marzocchi's have been in performance the North American arm of the company has been abysmal in service. That is about to change.

In the process of scouring the globe for service parts I learned that a well-respected company in the US off-road world has just signed on to distribute service parts here in the States. More when they sort out how they intend to make those parts available, but for now that is very good news. We'll be stocking bushings, seals, o-rings etc as soon as they are available.

Regrettably I have had parts on back order for the 48"s since June 2012, from gasgas Spain.so I wouldn't get your hopes up.
Props to my dealer though,he offered to rob a new bike for the parts,but STS suspension was able to machine parts to work in the mean time.

Steve is to be commended for his efforts, and I know he has been trying hard. I really hope it does work out but I have my doubts. I'm in the "hope for the best but plan for the worst" camp on this. Like I said before we need some custom hardware to use easily available consumables.

Otherwise, there will be a lot of 48mm forks dead in the water when its eventually time for cartridge seals or PFP seals.

What size is the little air bleed screw on the top of the Marzocchi 48's.
I need a new one as one of mine has been stripped.
Having a few issues getting it out too by the way.
Cheers Mark

Was this ever finalized?

Marzocchi doesn't list a u.s. importer for enduro motorcycle parts/forks.

Common wear parts (seals/bushings) can be easily had for this fork as they use same as KYB fork.

Manual for the marzocchi 48 enduro fork can be found on the marzocchi website - direct link to it is here:

http://moto.marzocchi.com/System/12002/manual%2048.pdf

I will grab this manual and place it on our site here so that it is quickly available - the marzocchi website can be *very* slow.

For service of marzocchi, sachs and ohlins suspension in the United States - I highly recommend Les Tinius at LT-Racing in Port Orchard, WA - he has more experience with marzocchi/sachs than anyone else in the U.S. - website url is www.lt-racing.com

Hey Jeff, can email you the reiger parts list and exploded drawings so you can put them up too.

Hey mate not sure on the size/pitch but the air bleeders for jap bikes will fit so well it appears they are a common enough size.

 

[wence]

Thanks everyone,
They are 4mm by the way.
Now to try and remove the old ringed one?
Cheers Mark

 

[jpgibson]

from memory,its a 4 mm ( ddunni the pitch) , ktm bleeders fit.

The US importer is ZipTyRacing, and while not exactly everything we'd been hoping for, they are much better than the mountain bike guys.

I would say that common wear parts are SIMILAR to the KYB, just as the Sachs forks use some parts that you could mistake for Kayaba pieces.

This is only worth mentioning because we're on our fifth set of Sachs forks and shocks this month, and the Marzocchis are crossing the bench with delightful regularity.

As a related aside, we're finding extremely worn inner surfaces of the upper tube on both the Sachs and Marzocchi forks, from both Beta and GasGas. Two things can help mitigate the issue - extremely low torques on the lower triples, and frequent oil changes. If your oil comes out like grey pudding you might as well scrap that leg.

What kind of torque do you recommend on the clamps?

I have just gone through and checked my entire front end on the 12 and found that the forks had actually pushed themselves up 4-5 mm on the left leg and 2-4 mm on the right. Needless to say my torques are a bit tighter than what they were. I also had problems with the front end twisting all the time too.
Found a bent brake rotor, fork heights had changed, stripped 6mm axle tension bolt and replaced both bleed screws.
Removed and serviced the brake, bent rotor straight, bled brakes, tightened and lowered forks to where they should be and realigned it all.
Hopefully that will fix my dodgy front end issues?
Endurox takes it toll on the bikes that is for sure

Any idea if the damaged legs had the bush land mod to allow the top bushing to pivot more? Do you think this could also lead to the excess wear?

Not likely Nath. Its the cause of said issues really.

In any case, I wouldn't run more than 13Nm on the lower clamps and only run 2 bolts. Mine had no mods and I tracked down the wear and source of grey oil in mine to be within the cart. Moved from one leg to another and contamination central in no time. Bit of a shame really.

 

[n_green]

I've run 8Nm on all three lower bolts for the past 50hrs, about to pull down, service and revalve so I'll see what they are like. No issues so far, fingers crossed.

That would be great. Thanks. You can e-mail me at webmaster@gasgasrider.org.

thanks!

The issue with tube wear on the upper fork leg is partly a thin wall on some models and partly that it is too easy to overtorque the pinch bolts with 3 bolts used in the design. GasGas should go to a two bolt bottom clamp - with your three bolt bottom clamp you should properly torque only top and bottom bolts and just snug the middle one. This is what Glenn did, so it must be right! ;-)
