750 Sport restoration project

[Andrew2]

Apologies for adding to the thread creep...

Here's what I've been putting together for the past few years. Exhaust headers and brake lines added since the pic was taken. Might have it finished before the rainy season.

Yesss.I love it.

Cheers

A bit more progress today.Here's the new shock from a 900.



The motor and the frame.



The motor in the frame



Now to start cleaning up bits and pieces and put it all back together....could be another 12 months at this rate

Looks good. I'm roughly at the same stage on my bike. (need to update my posts)

While you have it apart, I recommend putting seals in engine for the swingarm pivots. Easy to do now, and relatively cheap. The sizes is on the seal itself. There are single and double wiper seals. Since this is a low rotation seal, I recommend the double wiper sea for longevity.

Also, you will need to set your shims on the swing arm. Tighter is better. Chances are, the old setup had some free play. Shims can be had from your Ducati dealer. The 28mm pin was used as far back as the late 70s twins, so anything you can find in that range will fit. You can also find them as an Arbor Shim Kit. I bought a 1.125 id kit that worked well to augment the stock shims I had. If you have two pivot pins, it makes the job a bit easier, but it just isn't an easy job. A bit of thick grease between the shims will help hold them in place while you get the pin all the way through.

Cheers,
Phil

It's slowly getting there mate.I must admit I'm spending more time turning the little XT250 into an adventure bike at the moment.

Thanks for that info Phil.I think I may have some shims somewhere but in case I don't I'll look into the Arbor shims.What are Arbor shims used for?.

Arbor Shims do the same thing as they do on your swing arm, they take up slack in between shafts and bearings. They often come as a kit with a bunch of different thicknesses, or you can buy them singly. A quick google search will find you plenty of them. Basically, they are washers made from shim stock, and are generally measured by the ID (and of course the thickness). Comes in regular steel and stainless, and even brass, but you would want regular steel, or splurge and get the stainless.
At a minimum, you need at least two washers on each side, and ideally 3. Thick ones against the case and swing arm, and the thin one in-between. Basically, you are creating a large surface thrust bearing.

Put a drop of oil on them occasionally to keep them in good health. Once set up properly, they should last a lifetime. Talking with Ed Milich from Duc Power/Guzzitech , many from the factory were set way too loose. (probably easier to assembly, and nobody checked their work).

If I'm not mistaken, the old bevelheads used arbor shims to set the backlash on the bevel cut gears.


Cheers, Phil

Thanks for that Phil.It's nice to know there's an alternative to buying shims from the factory.I've cable tied the original shims to the swingarm as they came out so it'll be interesting to see how close they were when I reassemble them.

Hi Andrew, mate I was just looking through your resto pages as I havent been here for a while and wanted to show you something that I have found over the years of making/restoring ducatis is a good idea. That big ugly rear fender you probably wont use is in fact very useful but yes ugly. get a marker and a grinder. mark your desired line, use the 1mm cutting wheel and take the rest off carefully. change to 6mm grinding wheel or flap wheel and clean up. finish with sandpaper. cheers Sean
