Anyone know of a place to get an old 888 fork serviced?

Like the title says - I have a friend with a circa 2004 Demo 9 and a Marzocchi 888 fork that was serviced by a local-to-him shop in Denver, Colorado that is now leaking profusely. If I recall correctly this generation of Marzocchi had separate oil seals and dust wipers, and I suspect that the wipers were replaced but perhaps the oil seals weren't (or were done incorrectly). 

So far Dirtlabs in Colorado and Avalanche have both declined to service the fork owing to age. Any other ideas? I would offer to do it myself but my friend is a 6 hr drive away which makes it impractical, and my expertise only goes as far as lower leg service and I figure a full service of all seals is probably a good idea.

If it's functioning correctly but just leaking, any shop with a 35mm or 38mm seal press and seals (IIRC, there were two different size stanchion sizes over the years unless that was just the 66?) can do it. Finding the seals might be the hardest part. You are effectively just doing a lower service anyway, just with around 280ml of oil in each leg rather than around 10ml! Maybe the shop forgot to re-install the retaining clip that holds the oil seal in place, like I did on a 66 the other week..... I noticed it when cleaning my work bench.... Luckily I managed to get the wiper seals back out without damaging them and saved all the oil.

Looks like Mark can get his fork serviced for about $150 which seems reasonable considering seals, labor, and huge oil volume, so he is going to send it off soon. Thanks for the suggestion!

Yeah - I wish that most local shops were trustworthy enough to do a seal swap without any issue but I don't really think that's the case given his previous experience with a clearly botched installation of fork seals by a local shop. Most shops in Denver basically told him to throw the bike away and declined to service it when he removed it from storage to get it rolling again which was disappointing to hear.

Thanks for the suggestions - will send these along if MTB Forks by Mark doesn't happen to work out.

Its really not that hard. Golden Spectro 125/150 weight oil, SKF green seals & a seal driver. Really quite simple, have done it a number of times. 

If you want to try it yourself you'll just need a few things:

SKF Green seals (they are the best, worth the extra $30)

Slickoleum/Slick honey (to fill the gap between the dust & oil seals after istallation)

Pedros DH tire lever (Great for popping seals out, rag between the shaft and lowers to keep it from scratching/chipping)

Proper seal driver, not sure if you're 35 or 38mm.

Golden Spectro 125/150 (stock Marz oil)

Figure out the year and exact model for oil height: http://marzocchiworkshop.blogspot.com/p/oil-quantitys-and-levels_858.html

Once seals & oil are in, cycle the damper slowly 30x, pump the stanchions up and down a few times, reconfirm oil height (pen or pencil with a mark at the proper height will work for measuring)

Anyway, not tough, just go slow. Will probably be better than any shop can do as the cheap seals do not work great long term, and most shops don't use the correct oil or fill the gap between the seals per Marzocchi's recommendations.
