Marzocchi Pro w/ETA: Changing Oil?
Not finding anything in the manual except an admonition to do it every x hours.
Web site doesn't seem to have anything more. Am I missing something? -- PeteCresswell |

Am I missing something? -- PeteCresswell No you aren't missing it in the manual. Marz does that to promote "authorized" mechanics work on the forks. You can do it yourself it is easy. The thing that you should know is that the amount/height of the oil from the top of the stanchions when the tops caps are off and compressed is important. If you like the way the fork rides now and it isn't bottoming out then just measure the amount of oil you take out and replace it with the same amount. |

'Zocchi specifies the oil volume in ml - a Good Thing, I think compared to the vagaries of measuring height as they had me doing on my X-Fly. Only reason I'm changing the oil is that the damping function of the fork doesn't seem TB working - regardless of adjustment..... gets too boingy-boingy on repeated hits - like a car that keeps bouncing when you push down on the front and the shocks are shot. -- PeteCresswell |

RE/
'Zocchi specifies the oil volume in ml Funny thing, though: their web site's oil level specs don't seem to make sense. My fork's oil (from factory...) was at the top of the righthand arm with the shock fully compressed - yet http://www.marzocchi.com/spa/mtb/pro...ito=mtb&Y=2003 says it SB only 5ml and both http://www.marzocchi.com/spa/mtb/pro...ito=mtb&Y=2004 and ....2005 say 140 ml. Neither one seems to fit. The shock won't hold 140, even when fully extended. OTOH, 5 ml is clearly at odds with the 60-80 ml that I found in there... -- PeteCresswell |

Didn't have a clue, since the spring assembly prevents a view of the oil level...so I just added about 5cc on GPs... -- PeteCresswell |

You need to adjust the rebound to a slower setting. It's been all the way to "Slow" with no improvement. Changing the oil seems to have done the trick - although cranking it all the way to "Slow" doesn't make the rebound as slow as I'd have expected. I'll have a better idea of whether it's imporved next time I try negotiating those four erosion-barrier tree trunks in a row where I almost did a header into a poisen ivy patch because of the bouncing....-) The viscosity of the oil that came out was almost like water compared to the 7.5 stuff I replaced it with. -- PeteCresswell |
