Has anyone stripped one of these rear shocks? I am contemplating it and if there is any guidance out there it will be appreciated. |

Sorry, I have played JUST with Paso Öhlins and later version of Marzhocci "Duo Remoto", but NOT with this earlier version of Marzhocci... To that later version its still possible to find spare part kit, but i am not sure, does that kit fits to this earlier Marzhocci unit....

I've disassembled mine to thoroughly clean it but never to the damper internals; I guess that's what you need to know right? If you just want to disassemble the spring, collar nuts, gas body, etc., you can remove the load on the spring by loosening the collar nuts. First use a caliper to measure the top nut's distance from the shock's top shoulder so when you reassemble everything you can put the top nut back to the exact measurement. Loosen the top nut then the bottom and the spring load will release. The spring is not compressed too much so all load will release before you run out of threads on the shock body. From there the other parts just slide off the shock. A local shop who handles Marzocchi said he would work on it if I needed so I'm guessing parts and rebuild service is readily available. Hope this helps. Tom |

Thanks guys, I did get to take it apart and have been informed by Marzocchi UK that Maxton Suspension can rebuild it. |

I'm here in the US and want to rebuild my Marzocchi shock also. I finally found a Marzocchi manual that is very close to being this shock. At least it indicates approximately what I will find when I open the shock. From what I can tell, the rebuild kit would only have an assortment of o-rings and one oil seal. From what I hear on the forum, the rebuild kit for the Paso 750 does not exist. Is this true? If so, does any one here have a good source for o-rings and seals. I'm thinking of taking it apart and measuring these and hunting them down from an independent source. I even have a new OEM replacement shock to put on while I do this, but it too has a slight leak from the shaft oil seal. Guess 20 years on the shelf has hardened the seal. I've looked at the cost of replacement shocks. Only one I can find is at Works Performance, custom build up but with comp/rebound adjustment, but at $600US. I don't have a problem with the stock shock performance, so am looking at the rebuild. I know my way around tools and such, so it's not rocket science, just a matter of finding a source for the wearable parts. Thanks for your help. Oh, yes, I've lurked here for some time. Have had my 1988 Paso for 10 years. Has a Weber that runs great (after 2 years of fine tuning, don't ask) and still love to ride this bike. It will always be in my garage. George |

George, do you have the manual as a file or could scan it ? Even if it`s not 100% this shock it may help someone. G. |

The manual is for Marzocchi Duoshock 45, 45 Remoto, and 38 Remoto. I have it in PDF format. It's the closest thing I've found to our shock with the remote res. Instructions are multi-language. Let me know where you want me to email it. It's 11.8MB in size so the detail is good. George |

curious as to where you ended up with your jetting I have been searching for a pair of 4.5 auxiliary venturi tubes for my 44dcnf without any luck so far have changed my emulsion tubes to f47 which seem to have solved most of the low rpm flat spot around town. Also swapped out the stock coils for a pair of dynatek coils but with the weather and my work situation have not had the chance to give them a try as yet |

higgy, try to spend one day(surely weekend!!!) with internet and try to search, what cars have that Weber and search such carb from car wreckers.... There must be many of them, cause that Weber came such time, that just those cars are now in wrecking... Also there MUST be many "Weber maintainers" in USA, so try to contact to them and ask about such veturi tube...

Antti I have tried all the suppliers here and in the UK as well as Italy. They all are surprised they dont have it but all say it is no longer available. I have been offered a set of 4.0 which I might try in the end,from Pierce here in the US They are where I got the f47 emulsion tubes I got the info on the jetting from a Ferrari forum. In Ferrari/Maserati land it is quite a common swap to put 44dcnf in place of the original carbs and they all love them. I am happy with the way the weber works now,but being the way I am I know it could be better so I will keep looking or just bite the bullet and make my own adapter for the tubes I have. |
