Want to upgrade to City Grip 2 on the rear of my 2018 GTS 300.
Can't pull the wheel off the axle because it's stuck to the swing arm.
First thing I went through was the upper right bolt extremely difficult to remove because the bolt is BENT. That's right there's a bend in the thing. Checked its treads that seem okay but why the bend. Did the bend ruin the inside housing tread? IS IT THE CAUSE for not being able to remove the wheel from axle? It's obvious that the installer has the PSI too high on the pneumatic. OR it wasn't calibrated. How about putting no seize on the axle at the factory!
Anyway after several attempts with pry bars and hammer taps to work in the BLASTER solution, I must stop for fear of breaking something.
Does anyone has a suggestion to separate the wheel off the axle? Robot has a $40 tool to do it but there's a disclaimer it doesn't always work.
Please offer your suggestions.

You can screw the nut back on a turn or 2 and tap the nut/axle with a hammer to try and loosen the rust. Don't hit the axle directly as that can deform the end and the nut might not go back on.
$40 tool is probably best though.

We applied Blaster and heat with a gun to the axle shaft and surrounding area. Using a thermal scanner we started at:

room temp 77 degrees F tapped arm & shaft to help blaster penetrate. shaft still stuck
125 F strong taps on back of arm close to shaft and pulling on the arm with a crowbar. Nothing
150 F slight movement
175 F a little more movement
200 F no noticeable movement continuous Blaster application
225 F no noticeable movement continuous Blaster application
250 F slight movement
300 F we decided to stop and rest awhile and applied blaster and let it penetrate.
1/2 hour later tapping still failed to help so we went to 325 F
325 F and the hub slowly released exposing a slight amount of rust on the shaft

We'll use 000 steel wool and remove the rust and apply waterproof grease to the shaft; Is this okay?
Should the red bearing cover be pulled and the bearings repacked?

Out of the blue someone sent a LED head light bulb to me. WTF could it be from the company I returned the DC voltage lamp to? My Malaguti is AC voltage. Here's a picture. It has the correct base but is it AC? How do I test it without inserting it into the scooter socket and run the engine?

I'm in the same boat. '06 GTS 250ie, r. tire replaced by a motorsports dealer in 2018 or so. The plate rotates fine but no joy on pulling it off the axle (it just comes off in the video), tried leverage with a tire iron and -some- heat. I'm concerned about using a torch just under the gas tank call me crazy.

Not loving Italian designers today.

Pics attached hopefully. Thoughts and prayers always welcome.

I would suggest buying the right tool for this. At $40, it's cheaper than breaking something!

There are also a few threads on here about making your own using angle iron or by adapting a flywheel tool you may already have, etc.

Thanks Berto! I'll see if I can cobble something like that together

I haven't built one yet, so take it with a grain of salt... but I did take measurements at one point that might be useful reference if you're DIYing one:

I ended up having to cobble a pittman (?) tool from Harbor Freight and fabricated this bar out of 2.5" x 1/4" steel. Worked fine but surprised at how much force was required to free up the Vespa things. When I reassemble gonna put a light coat of anti-sieze on the inner race of the bearing and on the axle.

Looks like a good solution. I'm glad it worked out! Agreed on the thin coat of anti seize!

Did you end up using the measurements I had linked? Just curious if they were accurate, or off somewhere.
