When I fully compress the rear shock, the rebound appears to be undampened for the first 80% of the return travel, then is dampened for the last 20% of travel. Is it low on oil/N2? Service or replace it? |

Servicing is for sure cheaper. There`re used ones for sale once in a while but one never knows their real condition. If you decide to service yours take a close look at the damper rod. If the chrome is chipped or damaged that maybe the reason why an oil seal leaked. Over the time you`ll also notice that the swingarm linkage is oily. I had that on my first shock so I took it to the main Marzocchi importer. They told me I`d need to replace it as it was impossible to find a spare damper rod. According to them polishing or rechroming was no durable solution. So it would be important to find out why the shock doesn`t work properly anymore, if due to a damage or just as a matter of age.

Ok, I do understand the need for an undamaged shaft. What affect does the N2 charge perform? Could this cure my rebound problem? Is it possible to perform a "leakdown" test on the unit to verify the seals/o-rings are bad? Can I add oil myself somewhere? Do we have a manual for the specific unit used on our bikes? I'm asking because whenever I go to a shop around here without some idea of what to expect, they flat out screw me. |

Help! The shop that is rebuilding the shock can't find replacement seals or seal head. Does anyone know where to source these parts or have a cross referenced part from another vendor? Its a 14mm ID with a 40mm OD. My seal head has the hex head to accept a wrench rather than two holes for a pin driver. Thanks! |

these two shops list the complete rebuild kit. They do list every part number so one needs to ask about availability. http://www.store.commoto.com/ducatistor ... 76960.html http://store.proitalia.com/ducati-oem-s ... 18422.html Have you checked at a Ducati dealer with the part number (36640011A) ?
