How to refresh 350 Scrambler Telesco shock absorbers ?

[Rocla]

Hello,

Just the bevel gears setup is OK, I've discovered a leak on my Ducati/Mototrans 350 Scrambler Telesco shock absorber. How to dismount it? With which kind of tools ? And how to find parts ? I've seen some washers and gaskets on Eurotrash Jamabalya website but there is no indication about the model (it is not sure it matches Teslesco types)...
The model of my Ducati Mototrans is 350 Scrambler end of 1974.

Many thanks

Hi Rocla,

You can find him on ebay look for ducati singles , worldwide , the most offer from spain comes from hin.
But it is a little bit difficult to mail with him.

Hello again,

I've contacted some Spanish providers (and an American one too) but none has repair kits for Telesco shock absorbers, only used parts... I guess parts are still existing, even if Telesco vanished? Has somebody any idea to find such repair kits, for shock absorbers and front forks too?

I think you will struggle to find many new spares for Telesco forks and shock absorbers.
The 35mm Telesco forks fitted by Mototrans used seals 45 x 35 x 7mm in size, which are easily obtained from bearing suppliers.
I'm not sure how rebuildable the Scrambler shock absorbers are.
The Telesco Hydrabag shocks fitted to some of the later Spanish Ducatis used seals 20 x10 x7.
If the damper rod of your shock absorbers are not pitted with rust, you may get away with new seals.
If they are rusty, it is possible to have them re-chromed, much like fork stanchions, but you may be better off fitting some after market shocks like Betors or Hagons.

I rebuilt the shocks on my 350 Sebring using water-pump seals from an 90's era Suzuki (can't remember the part No./model). In any case, if you're willing to spend some time, it shouldn't be too much trouble to track down some seals. The shocks also came apart easily. For oil I simply used ATF.

Thanks Jon and Nick,

For the fork, I've already the seals but it is a little bit shimming when I brake, I think it requires to remove the teflon parts too. Do you know their dimensions?

For the shock-absorbers, here below the picture of the model. Do you confirm the dimensions of the seals?
