Swingarm Breakage

When adjusting the chain tension the left hand end of the swingarm cracked where the cap screw is fitted. On that side it was easy to remove the cap screw, where the other side required some effort. After adjusting the chain then tightening the cap screw, it was just starting to grip then went loose, just a little bit more and the cracks appear. You can see the threads of the cap screw where the aluminium split.

The swingarm before chain adjustment.

Bit of a pain, just getting ready for our summer riding. Now more delays.

Cheers,

Fraser.

Hi Erskin,

Yep, he's being a good boy helping out. Looks like the 750 and 906 swing arms are the same, at least they are according to the parts manuals, they have the same part number.

Cheers,
Fraser.

Hi Fraser

Yep, this sure is a great community - Gerhard is helping me at the moment with the purchase of a starter clutch over in Germany (a unit made by a company called Ringspann - if it does the job I'll let everyone know) and sending it to me, saving me some money over what Ringspann's Aussie agents quoted.

I talked to Gowanloch Ducati about replacement sprag clutches, but they said the only ones they knew of for the Paso were SKF ones they had heard about which apparently did not last well. Other than that, they offered a "V2 conversion kit that uses the later model 916/996 - sprag Cost is $690" which came complete with "bearing housing and the ring gear (which is usually worn but are no longer available)"

I'll say it again that I thoroughly recommend a sliding adjuster conversion. This can be done by practically any drag racing specialist. Additionally, the box section swingarm of the 750/906 is ideal for this work, it being a heavy gauge aluminum. Since this failure has happened after many years of service, it follows that it will happen again.

Yeah but the eccentric adjusters are pretty much unique to the Paso's, look cooler and work just fine . Plus it would be way cheaper to weld up that split , redrill and helicoil it back to original :)
