It is streaming from the top for now. I will add play/pause index points as soon a some time opens up, or when riding season ends ; ))

I have tried this link several times but it is not working on my stupid computer. These are great pictures. I appreciate them a lot.

I am fixing to assemble all the tools needed for the variator/clutch service and belt change. I know the two special tools that I need to get from the Wiki but nowhere does it talk about the size of the bits. Can someone help me with that. I have the break bar, torque wrench, etc. I just need to know what size bits to buy for all the scres, nuts, and bolts. Thanks in advance.

That link was posted just over four years ago.

If you are going to be maintaining your vehicle, go out and buy a socket set, some wrenches, and a bunch of screw drivers. If you only buy the sockets you need for every project, eventually you will have a whole set, but it will cost you a lot more than if you just bought everything together.

If you don't want to spend money on new stuff, you can shop around for used tools. I have a whole bunch of Snap-on tools from the '50s that I got at estate sales. I have bought small boxes full of tools for $10 and vise grips for $1, but it is a bit harder to find metric tools that way.

I guess that I have a tool habit and it is hard to wrap my head around buying the absolute minimum number of tools.

I think my post may have been confusing to you. Let's try it another way. What size are the screws/nuts in the transmission cover? What size are the ones holding the filter box to the bike? What size is the clutch nut? And what size in the variator nut? Those are the bits I need. I understand your tool habit. I am the same way with cleaning products and air fresheners. But not tools. I will just buy the specific pieces. Thanks

What we were hoping to see
Try again, perhaps?

GTS Belt and Roller Change
I attended a GTS maintenance workshop (Thanks, Rolf and Rich!) last weekend. Immediately afterward, feeling confident, I ordered the parts and tools from Scooterwest to perform the variator belt change. They arrived two days ago, and I plan to do the work this weekend. This thread will also be useful for reference. Thanks, MVers, for helping me learn to do my own maintenance!

Use a 6mm combination wrench to block the variator as i do.It costs nothing.

^^Kool thanks for that.^^

This I wonder about,
"Do not use a screwdriver to hold the clutch instead of the special tool"
I have to wonder why two screwdrivers one on each side is not the same thing, forgive me if it is obvious to you what damage it will cause, I have automotive experience but am new to Vespa.
I have a new belt and Sliders I am installing next week, please enlighten me.
Thank you.

You'd need three hands, as the screwdrivers would have to be held at 90 degrees to the clutch bell in order to prevent any twisting moment onto the driven shaft (or clutch innards).

I use a U-bolt of the right spacing, with the arms bent at 90 degrees, for the US Vespas. Less than two dollars, and available almost everywhere...

I will have some help so an extra hand will be avail, thanks for the idea of the U bolt.
I am thinking the tangs will have to be bent at 90 drgrees to the loop to get a socket in there on the clutch nut, unless the U bolt was 4" long.
The threads on the U bolt wont damage anything?
I am replacing the front fender too so it will be at least half the day doing all this.
Wish I could afford to do some clutch work at the same time, new springs at least, oh well, one thing at a time for now.
Thanks for the tip.

Belt and Roller Change on GTS
I changed my GTS belt and rollers last weekend; no issues. I bought the parts and tools (Buzzeti variator tool and clutch tool) from Scooterwest. Much cheaper than the official Vespa tools, and they worked fine. That was one of the tips from the workshop I attended, by the way.

The threads won't do any harm. A picture:
