New Gilera owner here in need of your knowledge & experience.
It appears that the service manual makes a rather large deal out of changing the drive belt on my 2008 Gilera Fuoco. I am new to the MP3 500/CVT scene, but consider myself mechanically inclined. Special tools include the variator locking tool, which I will need to purchase. Are there more special tools required for this repair?
Can I bust the clutch nut loose by using the E-brake to lock out the wheel? Does anyone have a pearl of wisdom on this repair that they would care to share?
Ok, that's enough stupid questions for now. Please feel free to chime in...

The E brake is not enough to bust the front or rear nut loose using standard tools.

Even though I have the special tools, I don't use them for this job. Instead I use a standard automotive impact gun BUT I do mark everything prior AND a torque wrench is required for tightening everything up to spec come assembly time.

Sbaert,
Any other pro tips for belt replacement? I will be using hand tools (1/2 & 3/8" drive) so I will try the wheel block with the 27mm, I guess. Are the videos for the MP3 400 belt replacement exactly the same as the Gilera? I'm having a heck of a time finding a good MP3 500 belt vid.

To break the clutch nut loose I apply the parking brake, and also squeeze the rear brake while turning the nut. Works fine.

Madison Sully,
Cool!
I just put new pads on the E brake, and adjusted it nice and tight thinking it might work. If the dealer was the last one on that nut , I will get it off. Just waiting for the belt from Scooterparts. A local Piaggio dealer here wanted $246.00 for that exact same belt.... Craaaaaazy.
Hey, what else should I know about this task?

the clutch nut is reverse thread, best to use an offset wrench and hold the 10mm shaft still.

Jim C.,
I was also curious about that reverse thread that Oldasdirt had mentioned. Any videos specific to Gilera Fuoco that you know of?
