I finally have time to do work on my 998 today:
First, somehow I lost the important M5 screws and washer for the STM clutch kit. I checked my old pictures, and they were in the package, but I must have misplaced them, thinking they were just some of the steel/washer that I am replacing with ProTi Titanium bolts.
I realized I lost them a few months ago, then I had to order from Europe, and it took almost 2 months before they arrived. I don't want to replace them with ProTi Titanium since this M5 is a grade 12.9 or far stronger than Titanium from ProTi, which only goes to grade 10.9 equivalent.
I can of course order from Accu in UK, but this time, I just want original STM sourced bolt, but they finally arrived. Pictures below. What annoying is, turn out the bolt package already include washers, so I accidentally bought an extra serrated washers... oh well
:
I Test fit these bolts:
Then I was looking at the STM install manual, and it is in the Italian language... so I decided to just follow the picture diagram... little that I known, the back side of this install manual, there is an ENGLISH version
which I found out later...
It had been a while since I am working on my bike so my brain need to be recalibrated
If I follow the install manual, I suppose to install O-Ring behind this spacer, but since I did not,... well, right now, I install without O-Ring, but please bear with me...
Then I install the main clutch housing:
Next, I see there suppose to be 6 ball bearings, but I can't find it,... I am so worry I might lost them again, so I decided to disassembled the Drum Hub Group (which was pre-assembled from STM):
And I am so glad that those ball bearings are still in there (just hidden):
So I reassembled the Drum/Hub Group back. Also, I did tried to find ProTi replacement of that small M4 locking bolt in this picture, but that bolt is special with a head diameter of just below 6mm and I can't find any ProTi titanium equivalent with a head diameter that small so I reuse the original steel bolt,
add loctite 243 medium and tightened to 3.5nm
Next, I grab the ProTi Titanium M8 bolts I prepared to hold the main clutch basket to the crankshaft:
Test fit 1 bolt, and it is perfect (with slight over lap, but that's ok), however, upon reading Ducati service manual to find the torque (35Nm), I was surprised that Ducati require Lock 4 or Loctite 510, which despite my variety of Loctite collections... I of course don't have...
hmmm... so piss off. so now I have to order and wait for the Loctite to arrive in around 10 days before I can install this clutch...
But... the heck... I want to finish TEST FIT all the STM clutch to make sure I am not missing any parts to finish the install so I continue with more ProTi bolts install at finger tight only:
Yes, they looks gorgeous, but ... hahha those bolts will be hidden from view soon... but hey. at least I know I have them installed

Next, install the Drum Hub assembly:
Then the Secondary Spring Support, and after that the Secondary Spring itself:
Now, it's time for the sintered clutch plate followed by steel clutch plate until they consist the full set:
