Hello everyone.

Im from Romania and i want to service myself my fork on ducati monster 620 from 2003.

I have the oil and dust sealing, i have the fork oil, but i cant find the bushing.

I search for bushing everyware but i cant find them

I email ducati romania to ask for them and he charge me 400 euro for them.

I definitely don't afford that price.

I think i have a marzocchi fork. Bicouse i look inside the foot on fork and is rite some numbers and a big M latter.

Can someone tell me please the steps to fallow and where or if a must bui the busshing?


Sorry for my bad eanglish, i hope you understand me.

Regards

Your English is good enough to get your point across.

email Racetech... distsales@racetech.com They might be able to put you in touch with a dealer close to you, or maybe sell you the bushings if there's no dealer in your country.

Or maybe Kamna in Germany? We have Scandinavian suspension tuners here, so maybe they might know a Euro supplier.

Thank you all for greetings and response.

if i only know the exact measurement of the bush, maybe i find here in my country. But i dont know the size....

You need to strip down the fork to confirm it but the bushings are generally on the inner fork slider. So they should be around the width of that (usually 43mm ish or a hair bigger).


EEL

in case you are wondering how to strip the fork apart. Its pretty simple. Pry the dust seal off carefully and slide it down the slider. You'll see a metal retainer clip holding the oil seal in place. Slide that retainer clip down the slider tube. Once the fork oil has been drained and the fork cap and spring removed, pull the fork inner and fork outer apart in a quick motion.

Do that over and over and you'll hammer our the fork seal and have access to the bushing for measurement and removal.

Take notice of the order of the shims and bushings so that when you put it together again, you've done it properly.

bushings are about 10 US dollars ea generally.

I'm guessing your dealer is quoting you the price for the whole repair kit, which is about 250$ US here, still a lot of money, but does include the other parts you should be replacing.  The part number is 349.2.025.1A.  Bushings are not available separately from Ducati.  Are you sure you need bushings?  They usually last a long time.  My old bike still has the original bushings after 85K miles (135 km).  Not the best comparison, since they are Showas.

I hope some of this might help.

A few further hints which might help you:

Before hammering the seal and bushing out from the outer leg as EEL describes, use a hot air gun or propane torch to heat the area of the outer leg until it is hot to the touch (but not sizzling hot). The bush will come out much easier. Do the same when you re-install, and the seal / bush will go back in much easier. Very helpful especially if you do not have a sliding hammer for this.

When taking the upper bush off the fork leg, push the lower bush up against the upper bush while carefully (if you will re-use it) opening the gap in the upper bush with a suitable tool (I use an old nail puller which I've modified; it's broader and thinner than a screwdriver). In this manner, it's easier to get the upper bush out without damaging it.

Before installing the new seal, cover the sharp edges of the groove for the upper bush with electrical tape, and grease the tape. Don't try without doing this, as you will most likely cut the seal and ruin it.

You can download the Ducati spare parts cathalogue fro www.ducati.com:

The pictures are not always exact, but stilla good help if you're unsure which part goes where.

The forks are the same as the originals on my M800-2003(at least acc to the catalogues), and I serviced them several years ago before putting them in a corner. I can't remember for sure, but I think the bushes are the same as for the Showas. Not sure, though ..... so take them out, inspect and measure.

You could contact K-tech in the UK once you have the dimensions; they sell a lot of spare parts and I use their bushes, among other things.

Kind regards,
Torbjörn.
