Marzocchi Z2 Superfly restoration: FINISHED!!

Re: Re:

Fig. 30 on page 46 of the manual (p.23 of the PDF) gives instructions for filling stanchions with oil.

The oil will move freely between the inside of the stanchion, and between the it and the lower leg through the open end of the stanchion tube (hence the need for an oil seal). It is this movement under compression and being drawn into the rebound cartridge upon extension of the leg, that gives you rebound damping. The thickness of the oil will determine your rate of rebound (Marz recommend 7.5w).

The damping is all done in the stanchion, it holds the damping oil)

The lower leg is the main air spring, ONLY lubrication oil goes in there, same 7.5wt can be used though.

This it different to normal spring and later air bombers where they act with a big oil water bath in the lower and it moves freely around.
Later air bombers e.g. Z3 flylights act more like MAG21s

Re:

It is Fig 28 on the previous page that is the important one for here. note it say 77cc, it is only 7cc (7ml) as in the other language there.

Re:

Schooled!

I had coil (and apparently later air bomber) design in my mind. Didn't know the Superflys were different.

Signing off!

Re:

HELP NEEDED!

the dust seals are actually so tight that the sanctions go down but have to phisically be forced to return. there isnt any air in the forks yet but even so, the seals surely shouldnt restrict the movement of the forks should they?

does anyone have experience of/ an answer to this?

cheers

experience... yeah.. enduro fork seals are awful for this!!! they are too tight in my opinion... and even 6 months of riding didnt bed them in anymore..

mine acted like a friction damper and totally removed any small bump performance sensitivity.

mine went in the bin and i bought some decent seals..

the rest of the fork looks good though!

Re:

@spacehopper I ordered oil today so i'll see how they are when theyve had the oil changed lubricated and been pumped up. Sounds like i'll have exactly the same problem as you did

@fjpshaw if its okay id like to hang on to the tool until the fork is up and running. Cant say whether i'll need it again yet
