psycholist Posted November 18, 2009 Report Share Posted November 18, 2009 Use 7.5 Wt fork oil if you're happy with the current damping. All the Marzocchis ship with 7.5 Wt. Undo the top caps with a correct sized socket (Let any air pressure in the forks out first). Turn the fork upside down and pump it up and down to empty the old oil. If you're happy with the seals and don't want to dismantle the fork any further then fill the legs of the fork with new oil, pump the fork up and down to get the oil through the fork damping cartridges and then empty it out (This will clean the fork out some bit). If you've got IPA or some other solvent handy you can use this instead of fork oil and probably do a better job of cleaning the fork out. Refill the fork with clean oil pumping the fork up and down to make sure you get all the air bubbles out. Then if it's an air only fork fill the fork legs to the start of the threads for the top caps and fit the top caps. The fork will extend slight as you tighten the top caps. Press in the centre of the valve while pushing down on the fork till it bottoms out. This will leave the maximum amount of oil in the fork. Pump the fork up to the correct air pressure and give it a go. If the fork has too strong a rising rate (You can't get full travel) then take more oil out. A drop of a few mm in the oil height can make a big difference to the fork.If you have coil springs leave about a cm between the bottom of the threads for the top cap and the oil level with the coil spring sticking out of the fork leg. Back all the preload off before opening a coil spring fork (It makes it a lot easier to put the top cap back in). Quote Link to comment Share on other sites More sharing options...
Nic84echo Posted November 18, 2009 Report Share Posted November 18, 2009 Have a look at this - http://www.peterverdonedesigns.com/bikesuspension.htm - has a wee blurb on specific fork oils to use in different forks, Marzocchi is listed too. Good luck. Quote Link to comment Share on other sites More sharing options...
craigjames Posted November 19, 2009 Report Share Posted November 19, 2009 Marzocchi oil volumesAs is said Oil weight to be used is 7.5wt, using slightly higher or lower weights will slow or speed the damping up if this is not externally adjustable.
