Modern Vespa

I want to replace the single-tube bush set ( the one with the two sizes of bushes) on the '64 and I can't find much on this. Does it go in and out of the larger end as a unit ? I can drill them out if I have to but I can't seem to find replacements and the later pair I bought are wrong unless I can turn one down to the appropriate size for the smaller end.
I caught a glimpse of a set which looked like race bearings instead of bushings on SIP but their site keeps reloading (on the PC and the laptop) and I haven't figured out how to make it stop.
Any info on this type of bushing(s) appreciated.

Did a similar job today on a V50. Bushings are only available through SIP since Piaggio has stopped producing them years ago. I could have gone the easy way and "retrofit" the ones from a PK but I chose the "hard" way. Had to make a "dilator" to help the tube go into the bushings using a hydraulic press. I think the bushings you're looking for are the following...

The site reloads because you've probably checked the "Show only articles for selected scooter. " and using Firefox?? (it's a Firefox bug). On Chrome it works fine...

Thanks, SaFiS, those sure look the part. So, the bushes go in and then the tube is pressed through them ? I do not believe the nylon spacer/washer in your pic was present on this bike. Are they necessary ?

You were correct on the Firefox glitch, too.

Sorry for the late response. Yes, the bushings first go in and the tube is pressed through them. The nylon washers were original, bushings were never changed on this motor. They're there to prevent the bushings from moving and touching the frame. SIP reproduces them. This motor has the same bushings on both sides so the ones from a PK I mentioned are the following. The length of the one piece tube and the two halves (when combined) on this type of bushings is exactly the same. The only difference is that the PK bushings are 3mm bigger in diameter but they fit with a little persuasion:)

Yes. A few weeks ago I do the same - install the new bushings(like Safis shown) in my 50 Special. They works great!

Any reason not to do this ? Newer bushings ( one modified) on top of SIP stock type.

I turned another left one without the (unintentionally) chamfered edge on the inside and they felt right pulling in. They both hit the inner steps and ended up right where they should be.

Seems like a rational solution! As long as the diameter & fitting is as stock, I dont see why this wont work as good as stock. Good ingenuity!

I'd think most people dont and/or cant turn them down due to lack of access to a lathe.

Lets see if any of the experts chime in and offer wise advise
