Yours doesn't work?

He doesn't have one.

He doesn't like the price.

My understanding of Duc primary gears is the only puller that works is the factory tool. If you don't like the price of the tool, and I can understand not wanting to spend the money for one use, pay someone that has it to remove it.

Complaining about the price is pretty useless.

@ducpainter...  as i am sure you'd understand a lot of us enjoy the challenge of working on our own machinery, it's not only a challenge it's very satisfying and all part of the adventure, so it's annoying when things like this present obstacles.


has anyone replaced thr clutch basket without replacing the primary at the same time ?

This isn't facebook, or instagram, or twitter.

You can quote anything I say without using acronyms or special characters.

Everything is expensive.Tools are expensive. Quality tools even more so. You can buy cheaper pullers...maybe even one that might work.

The factory tool is priced like a professional tool that will work every time.

If you really want to do your own work complaining about the price is amateurish...if not childish.

Sorry.

I don't recall having to use a puller on the primary gear... It was a while ago though... I have a cheap 2 jaw puller, there ius a possibility that I used that, but I really don't think I needed one.

This is a castle nut socket someone made, same as I did:



& this is the castle nut on the primary gear:



I'd say whip the cover off & see how you go. If you can't get the primary gear off, it will work, but it may be very noisy & possibly have some backlash.

cheers MV
that clears up a lot, i was assuming you were referring to the basket retaining nut, which totally threw me off track

having delved deeper today i discovered the part #'s of the the s2r primary gear 170.2.077.1a and the 696 primary gear 170.1.051.1a   differ, suggesting they 'probably' have some physical difference.     so my primary must come off to match the replacement 696 basket to do the job properly.   i will also i buy a new 696 22mm retaining nut, which isn't a castle nut.

apparently in more recent bikes the primary sits on a spline, not a taper, making removal way easier

I swapped in a "normal" clutch from some 750 in the original engine on mine without swapping the primary. I don't remember if I knew it was recommended at the time, but I had no ill effects.  I want to say I had 12k or so on that engine at the time and I rode it till I wrecked the layshaft at over 39k.

I'm pretty sure I posted on here somewhere...

that's interesting to hear, i am sure i saw something similar said on another forum, but i cant remember where.
guess the thing to do if the primary is a pregnant dog to shift is to try it and see how they mesh, with or without excessive slack and noise.

i did find an instructable for a DIY gear puller that may work if scaled up:

the clearance with the casing may be an issue, the ducati tool is circular

I looked for a bit to find this thread...and unlike others, I'm very happy to resurrect an old thread if the information is relevant.
Sadly, the original poster never tied off the ending. Does anyone know if the M750 clutch basket is a direct fit for the S2R 800?

I'm also looking to get rid of the failure potential of the damping springs. I'd much rather have it without the "damping" feature than with the possibility of failure issue.

Thank you for any relevant info you may have.

Yes, the 750 clutch basket including it's large "springless" driven primary gear fits. We are often adviced to change the "dual mass spring loaded" drive gear too. Also; in pairs with the driven gear.
