Hi, I want to share with you this project, hoping in your help and support. The bike is a monster 796 '10, equipped with the classical aptc wet clutch, as you know it's not simple to state that's an upgrade or a downgrade, but there are many "romantic" reasons for the making of this mod.

Now, you now the dry kit conversion are not the cheapest spare parts, and on a bike that is worth 5000 euros, a 1500 euros mod sounds maybe stupid. So before I started I gather the more informations as possibile, and I find out that the mod could be done with 500 euros more or less, using used and new parts. As you know, there are two ways:

1) Split the engines cases change the primary gear shaft and then you will be able to use every spare parts of Ducati bikes with dry clutches.

2) Working on the OEM primary shaft with dedicated spacers and seals for the closing of oil passages.

I'm going with the second way, because in my opinion is the less invasive method, and I will be able to restore the bike as it was whenever I want.

Now, I studied the conversion kits from Kbike, Bursi and Ducati Performance the main manufactures here in Italy.
The ensemble includes:
- A clutch cover side
- Primary Gears, Bursi and DP kit use the Hypermotard 1100 ones, Kbike produces the gear on which you mount the clutch housing, so you don't have change the other gear on the crankshaft, that requires special tools and it's very hard in the removal manouver. Actually you can use also other primary gears from every Ducati bikes with dry clutches except for the testastretta and the R models.
-The whole clutch
-A special screw sprocket side for closing the oil passages, DP uses a tapered screw, while Bursi and Kbike an harder spring on the OEM screw sprocket side.
-A longer push rod
-A special nut with seals, that one works also for housing for the bearing of the new push rod.
Kits also includes other little parts and screw but nothing impossible to find.

Now I need some advice from Ducati wizards in this forum and from DP dry conversion kit owners.:x

I find out that spare parts of the DP kit are sold individually at the Ducati Store, my idea is to buy the special nut, the spacial spacer with seals that fits in front of the clutch basket and the special M6 screw that close the oil passage sprocket side.
Then I want to adapt a standard slipper clutch, I know the ducati kit has a special hub, made because of the presence of the special nut, so if you can help me I'd like to understand the difference between the hub of the 848's kit and a common hub for a Ducati Performance slipper clutch.
This is the main point, everything could help me, detailed photo of DP kit, a description or some ideas.:grin2:


The project has just started, I found a cover clutch side from an Hypermotard 1100, and the primary gears for the amount of 140 euros. In the next two weeks I'm going to work on the cover to make it similar to the ducati performance magnesium one, about that anyone know the code reference of the similar magnesium cover?! :grin2:

Then I will buy the spare parts of the DP kit, and a used slipper clutch.

Stay tuned

If someone want to help me I'm all ears. Thank you in advance.

Last question, in the DP kit there are two different lenghts M6 screws for the closing of the oil passage. The codes are 96855309B, 96862610B do you which one I need on the Monster 796?

This could be a pic of the screws, find on the internet. I don't know the respective references.

Then I want to apologise if I killed centuries of English grammar with my messages. I'm sorry, I'm italian. :grin2:

Wouldn’t it be cheaper to just sell the bike and buy one with a dry clutch ?
No, it woudln't. Firstly, as I said, it's a romantic question, it's a bike I'm very fond of so I'm not interest in selling. I bought my 796 as brand new in the 2010, and I love my bike, maybe a 1100 s would give me more performance and the dry clutch, but I would be forced to buy a second hand bike, and simply I prefer to maintain mine.

Then the idea of my bike with the tipical Ducati dry sound is very satisfying. >:)

I’ve not tried any of this, but don’t assume the 848 wet clutch to be the same as the 796. 796 is a small block, 848 is a big block. Lots of things may be different. Just expect the unexpected.

Thank you for your message! Can you explain me the differences? I knew that, in this conversions, the main issue besides the oil flux, is that the primary shaft is shorter than the primary shaft of the dry clutches engines. After your message I checked the parts of the 848 and 796's, clutches are very different, but also the primary shaft seems to be another. In particular I fear of thread diameter is different, in this case I won't be able to use the 848's special nut on the 796. Can you confim?



P.S. Merry Christmas everyone! :grin2:

2019's update: just find out the special nut from the Ducati Performance Dry Kit for 848 doesn't fit on my 796. This is because 848 nut is a M20x1 while on the Monster 796 nut is M25x1.5, it means I'll need to design a nut by myself or think about other solutions.

Ah I see.

Have had a simular issue as you do, but that was fitting a STM 1098 clutch on a 848 dry clutch conversion.
Had someone make a custom titanium nut, since STM couldn't provide the one I needed.

You could ask Bursi Evolution they pretty much sell every part there is for their dry clutch conversion.

96862610B is for a Ducati 848 EVO no idea about the other part number though.

Yes, maybe contact Bursi is the smartest idea,:wink2: in this period I'm very busy, so I'll do that in a couple of week. First of all I'd like to finish the clutch cover, in order to put on the new primary and the cover sealing everything.

For the screw, is not a big problem, if I'll contact Bursi I will ask him also for the hardest spring he made for the regulation of oil flux.

Did you change your OEM wet clutch with a STM from 1098 without the DP kit?

The project is going on. Today I went to the Ducati Store and I ordered the spacer that fits behing the primary, and most important I bought from an Ebay seller a complete Kbike slipper clutch, basket, plates, everything at really low price. I hope they won't send me a stone :grin2:

No. It had the 848 dry clutch conversion. The 1098's shaft is larger, thus a smaller nut was needed to get the 1098 clutch fitted on the 848's shaft.
Ok, copy. I guessed the 1098 Stm clutch would fit on your bike using the DP nut. Maybe is not so simple.

Ok guys, it's time for the february update. I've removed the OEM clutch, primary and the push rod. Sunday I installed the new hypermotard 1100 primary gears, the oil pump of my 796 fitted perfectly. A small issue has appeared when I tried to use the OEM spacer from dry models with the thickness of 2.8 mm, in fact with this one the bigger gear touch in the engine case, so I made a new spacer (thickness 4.0mm).

The main problem is that my shaft is shorter than the one on the dry clutches ducatis, so the solution is to machine the clutch hub in order to create a cavity in which I will mount a special nut as the Ducati Performance kit.

At first I bought the 848's special nut in order to modify this one and widen the thread, but this is not possibile because there is not material enough.

So now I'm designing a new nut, M25x1.5 in which I will mount the seal code 93785082.
