My 400 has the boge shock on, it looks ok to me, not sure how long it's been on it for mind. I'll have a closer look later to see if there is any sings of damage.
Here is what I found and asked Ducati Italy about: The main thing to look at is the lower eye of the Sachs Boge shock as it rotates across the bike.....the large eye will make contact with the swingarm lugs on my 900 ss ally swingarm. Maybe your swingarm has different lugs??
And now something completely different..... How does one get the swing arm pivot out. I am assuming you need to drive/push it out, but it is hollow with very little meat to use, oh and the reverse thread on the the drive train side had me going for a while.
A little quote from John Falloon's bible Ducati Supersport:- The 1991 smaller Supersport were the 750, 400 SS Junior, and 350 Sport. Many more 750s were made 1,872 as against 500, but these also included 1992 model year bikes produced after September. All were red, with white wheels and frame, and had a quite basic specification and chassis to keep prices reasonable. Most were fitted with half fairings, and all had non-adjustable 41mm Showa GD031 front suspension. The 350 sport and 750ss shared their Showa GD022 shock absorber with the larger 900ss, but for some reason the 400 SS Junior had a Marzocchi PBS1R shock absorber.
Well, done Lumbux.........Look at what I guessed at a few posts back Reverse thread......where? I not got one..... Can you use the rear axle to remove the swing arm pivot? Should be 17mm IIRC. The Showa shock bushing fits between the lugs, but allows the shock to twist. I also fitted a thin shim washer so as to take up a little bit of looseness between the bush and the lugs on mine, so it didn't put strain on the lugs when I tightened the bolt.
have you looked at a Marzocchi PBS1R, that's one ugly shock. did think about putting one back on the 400 to make it original, but don't think I can bring myself to do it.
There is also reference to the fitting of alloy swing arms in the book a little further on, but no mention of them being different to the 900's swing arm. The plot thickens and I'm digressing a little, my apologies.
As far as I can recall, Lumbux; when I saw your 759 swingarm, I thought it was different in some way to the earlier 900ss one I have fitted......Trouble is, I can't recall what it was that I saw.
The lock bolts are the wheel side of the pivot not the engine side, and the engine side end is round not square.
The 900 had the same swing arm as yours all, and the 750, 400 and 350 had the other type. Not sure why, the 750 sport, paso and I think 851 all had another type of swing arm too.
It's not ugly as such just different, you wouldn't see much of it by the time the body work was back on.
So to answer my own question, you need a 19mm and 17mm Impact socket a dead blow hammer and some socket extension shafts, so we now have the bike in this state And the rest of the bike resting on the engine dolly like so So next week should see the engine and frame finally separate after 24 years
