'92 907ie cush drive

[vtduc]

Back to VT from Quebec today , as I rolled the bike up one the center stand I could hear something rolling around in the wheel. One of the cush drive bolts apparently sheared off. I believe these are the older style ,thinner bolts but not positive.
Anybody know the size of the old/new bolts so I can be sure and if they can be had ? If not where do I get a cush drive.

thanks for any help

I don`t know about different bolt sizes but #82110091A (current #82110091C) are the same for
Ducati 750 SS `91
Ducati 851 `90 SP
Ducati 851 `91-`92
Ducati 888 Superbike `92
Ducati 888 `93->
Ducati 900 SS `90
Ducati 900 SS `92
Ducati 900 SS/SL `94-`97
Ducati 907 I.E. `92
Ducati 916 `94
Ducati Monster 900 `93
Ducati Monster 900 `94

The bolts of 749/999 have a different part number.

The cush drive is the same on
Ducati 851 `91-`92
Ducati 888 Superbike `92
Ducati 888 `93->
Ducati 900 SS `92
Ducati 900 SS/SL `94-`97
Ducati 907 I.E. `92
Ducati Monster 900 `93
Ducati Monster 900 `94

If you can`t find anything else or lost the trust in original parts these may be an option

pm:

The bolts on pre '95 ducatis are a thinner diameter (non-single sided swingarm) no longer produced by Ducati - from -Desmodue/LTSynder

Well, what I posted last are the original partnumbers from the 907ie parts catalogue and it`s no problem finding those parts.
Newer Ducs have different part numbers for the bolts and cush drive. The last is for sure because of thicker rear axles i.e. an ST2 rear axle is 25mm. The cush drive rubber part numbers are always the same so the thickness of the pin didn`t change.
If you then check the website of JT sprockets or other manufacturers it shows the dimension of the rear sprockets and if you compare the bolt hole diameter of an ST2 and a 907ie sprocket it shows that they are both 10,5mm so I wonder what LT Synder is referring to. (the bolt holes on a 906 are 8,5mm but that`s a completely different wheel).

What you could do in case you cannot get the info here is to contact some sellers on ebay and have them check the measurements with a sliding caliper.

I had one of the cush drive pins on mine shear a few months ago. When getting a replacement the dealer sent me the wrong one - from the later models, same as my ST.
The early pins as on the 907 have an M10 thread which screws into the sprocket carrier and also retains the sprocket with nuts on the outside. The later pin has an M12 left-hand thread which screws into the sprocket carrier and then steps down to M10 with a RH thread to retain the sprocket. To fit the later pins you'd also need to fit the later sprocket carrier with suitable bearings.

I love this forum

Any idea where i can get the old style bolts.

If I need to replace the cush drive will the newer-post 95- drives fit ? sprocket ?

[Derek]

I got mine from my dealer. They are still available no problem.

Thanks Derek,

I wonder if there are left hand metric M12 thread inserts like Helicoil. Probably hard to find but if there was a shop they could drill out the M10 thread of the 907ie sprocket carrier and mount the new type pins (if the threaded section of the old and new pins have the same length).

Another possibility would be to get a used ST2/SSie etc sprocket carrier, remove bearings and bearing spacer and measure the outer diameter of the bearings. Then take the 907ie sprocket carrier apart to get the bearing spacer, measure the required inner bearing diameter and go through some catalogues to see if there`s a bearing that lets you combine the old bearing spacer with the newer sprocket carrier.

The measurements of the rear sprockets of 907ie/ST/SSie etc. are the same btw.

Just an idea if someone stumbles over this topic in future.
New pin bolts are about $26 ea. (€17,50 at Stein Dinse). Makes them even more expensive than those titanium bolts linked above. However those are the post `95 type as I`ve now learned.

[vtduc]

so far no dealer has the old style pins.(82110091a). I'm trying to find someone who has 1 or 2 laying around or a '92 cush drive I can either swap out or get a pin from.

Just get a second hand drive.
Like above, lots of other models fit,
I have one spare fr my M900 -97 if you don't
find one in the US.

this is the newer sprocket carrier if you`d want to try if it fits with different bearings

and here`s the old type

Thanks for the EBay link G . I got mine apart without any further loss and I may have found a bolt . b.t.w. what is the torque setting for the Cush drive bolts ?

[paso750]

that info is in the workshop manual 34,3-37,3NM
The bearing type in the cush drive is a 6005-2RS1/C3, isn`t it ?

Tht bearing is the same in:

Hence it seems one could just swap the bearing spacers and then use the newer sprocket carrier on a 907ie.

Had a similar, actually same problem with mine, check out the link.

I used the complete drive sprocked carrier from an early MultiStrada which slotted straight in. Saved a LOT of cash.

Goodluck.
