Modern Vespa

Hi, I come here for a little help.

The Chain Support Gasket 1A018560 is not available in factory, and don't have a ETA so I'm thinking in do it myself. Anyone know what is the correct thickness and what type of material needs to be used, as I don't have the old one?

This Chain Support Gasket 1A018560 is used in the 2021 Beverly 400, the MP3 400 2020 and 2021, and the MP3 530 2022.

Thanks in advance, regards

For those who don't know their part numbers off by heart, this is the chain tensioner gasket for those models.

I don't think it matters much about the exact thickness, as the tensioner will surely accommodate quite a range?

Agree.

My biggest concern is about the material type as I thing paper or cork is not the correct one, and not sure if metal or some fiber, that's why I come and ask.

I've got a new and a used one for the gts300. can measure when I get home.

hmm, looking at https://www.p2r-expert.com/en/piaggio/209660-1A018560.html it appears to be smooth like the gts300 head gasket not the slight textured that iirc the gts300 chain gasket has ...

both though are clearly metal not paper or cork

thickness isn't so much of a concern. any type of fiber or reinforced paper style gasket material will be fine so long as it's oil resistant. avoid cork.

a little gasket sealant isn't a bad idea if you're using something other than the OE style gasket.

To me, from the few photos I have gotten (and most of them are pretty bad), it looks like something like fiber or something similar to asbestos (I imagine some substitute), I assume it must be a material with good heat resistance and logically oil. That's why I'm asking to see if anyone has any ideas.

check amazon something like this has what you need and a whole lot more. gasket material Muti pack

the blue stuff or the grey stuff is what you want.

or something like this felpro gasket roll

a lot of auto parts stores also sell gasket sheets.

honestly a plain cardboard file folder with sealant would be fine too, if you were in a pinch.

Ha Ha Ha, I have this exact one searching in my drawers, then let me check if the blue one or the grey to cut the gasket.

Thanks a lot

The number of times I used cornflakes packets...

probably should use Weet-Bix or All Bran for more fibre in your gasket

empty 12 pack boxes from consumed wobbly pops, manilla folders, a court summons... anything is fair game in a pinch.

I broke a shift fork in my transmission and locked the damn thing up between 2nd and 3rd. thankfully I was able to limp off the highway. I pulled the car up onto the parkway parallel with the curb so I could shimmy under it and pull the side cover. I extracted the busted fork and flipped the other so I'd have just 2nd and 4th so that problem was solved but I still needed to seal up the side cover.

the "truck stop" in this shithole town didn't have any kind of schmoo so I got extra creative. I bought a few quarts of gear oil for the trans and then stole two giant stacks of paper towels. them thick nasty industrial brown ones.

I proceeded to layer the paper towels with a schmear of axle/brake grease forming an impromptu gasket situation that I could only pray would get me home, or at least close enough for a tow not to cost me a bajillion dollars.

somehow that worked and it didn't immediately puke all the oil out and with some fancy foot work I didn't totally roach the clutch starting it out in 2nd, making the rest of the trip home without incident.

once I got home I swapped the trans for another one I already had holding down the garage floor and promptly burned my clothes due to the gear oil stink.

I'm assuming you have a handy large pile of these

they sop up oil quite well

but are they cheap?

I plead the 5th

Given that it's Piaggio, is this the same gasket as they use on the Beverly 350 with a new number? 847928 is that part number.

No, is round in center and biggest opening is used in the 2021 Beverly 400, the MP3 400 2020 and 2021, and the MP3 530 2022

Here a reference picture

that looks like an exhaust manifold gasket

double check that part number

Agree that looks as a exhaust gasket but is for the Chain Support, see the next picture, the one below is the one that always was, the one above is the one I need, look at the shape

i would just cut one from head gasket material and use a thin coat of gasket sealant

Not a high pressure location i think (use court summons for style) but Here are my measurements as promised

Gts300 rough measure (don't quote me):

Old and new head gasket .2mm and smooth.

Old chain gasket .2mm in the middle where squashed. rough around the edge where it sticks out about 1mm - about .3/.4mm there.

New chain gasket .5mm and coarse surface.

(All are metal).

you're correct, it isn't a high pressure location and it's not submerged in oil.

a paper or composite style gasket with a light dressing of sealant would be more than adequate.
