Does anyone know the o/s diameter of the "nuts" in the transmission ? I am going to try to find an affordable socket for this . I see Motion Pro sells some of these sockets.

The Moto Guzzi Parts Catalog shows three of these "special tools" . . .

34mm GU 019 13 430

28mm GU 019 13 830

24mm GU 019 13 730

It is not specified what the "mm" designation refers to, perhaps the thread diameter of the "nut?"

Thank you .

I can probably measure mine in the next few days. They’re at Michael’s workshop though and his new crane is being installed at the moment so the place is a shitfight but I’ll see if I can dig ‘em out and measure them.

Having a socket is infinitely better than buggering about with alternatives, believe me.

Thank you , Pete . I am gonna take the #s Docc posted from a workshop  manual and see how much OEM tools are also ?

Unless similar nuts are used in some of the later bikes, (And apart from the pinion nut in the CARC bevelbox I can’t think of any.) I would be very surprised if the factory still has them available. Certainly the CARC six speed boxes don’t use them and I’d be surprised if any of the smallblock, three shaft, six speeds do either.

The V100 I know next to nothing about but from reading the manual I can’t remember seeing or having reference to any similar fasteners.

ok. I will check eBay w/the hopes someone has some to sell if I can't get some dimensions and come up w/something .

No, they don't. I've had my V35 Imola gearbox open a couple of times. You need something to hold the input shaft to get the nut off (110 nM), and a longisch Allen key to get to a particular screw inside, but that's all. The rest is standard metric nuts and bolts.
