Marzocchi forks info please

[shifty_steve]

Are these old Marzocchi forks any good, they seem heavy but look solid - think they where made in 2000 because there is a date type stamp on each leg, not sure what model they are ?

Is it possible to DiY service these type of shocks ?


is this the year of manufacture ?



cheers for lookin

Yes. The adjusters indicate Oil&Coil so its nothing tricky or difficult.

Not knowing but guessing i'd say its the 2001 Z2 or equivalent for that year.
(for some reason the crown date is a year before release. Stamped 97- released 9

Whats the issue ? Weeping seals ?
Because if not then its likely nothing needs done. Theyre a fit and forget, and forget for years at that.

cheers Dyna, seems they might be Z2 atom bombers and they have no signs of oil driping or weeping so maybe just crack on as is.

thanks

Re:

Service on those forks is fairly simple. Almost as simple as draining and refilling oil. You don't need to drop the lowers for an oil change, just unscrew the top caps. Make sure to purge the old oil from the cartridge when draining & purge the air when filling. Golden Spectro 125/150 is the factory oil.

These older forks require you to fill within a certain distance from the bottom of the top cap threads in the stanchion. Internet says you need to fill up to 40mm to the bottom of the threads.

I'd ride em until the seals go. A quart of that oil will do many oil changes. If you feel nervous I'd recommend to watch a few marzocchi fork rebuilding video's on you tube. Most of their models are pretty similar even now.

Dead easy, I would pop the lowers of as it's as easy as two bolts, and you can have a good clean and check around.

7.5Wt oil from CRC or similar will do or 10wt+ if you are heavy with all your riding gear on.
Don't bother looking fo Golden Spectro 125/150 as you're in the UK.


Evan a full seal and bushing rebuild is pretty straight forward, but until they go, don't bother.

You'll find manuals here and elsewhere on the web http://www.retrobike.co.uk/gallery2/v/M ... intenance/

Technical manual is here with more insight in to what things are
http://www.retrobike.co.uk/gallery2/v/M ... s.pdf.html It only goes to the 2000 models, but they are near enough the same in 2001 for the general models.
