Modern Vespa

I have been researching to verify these values, but am getting conflicting numbers via my research that clash with what my service manual says.

Are the torque values listed on this page of my service manual correct for the 5 nuts that lock the rear wheel to the brake rotor?

33-37 nm? Meaning around 26 ftlbs.

Yes, the same as for the front wheel screws. See "Tightening torques" at the front of the workshop manual.

I don't know what you mean. Are you saying that the value of 33 to 37 nm is correct for those 5 bolts?

As for the front wheel, there's 2 allen bolts that are like 6 to 7 nm, and 2 nuts holding the wheel on. Is that what you are referring to?

It on here already,https://modernvespa.com/forum/topic187064 yes it is correct. 😉👍

Lol, that link is to this post.

Anyhow, thanks kindly. I wasn't sure as I had read conflicting numbers.

You guys are great. I generally work on cars, so this being my first rear tire switch out on my scooter has been a bit vexxing, but a learning experience. Appreciate all your help.

Yup pressed the wrong one, but did check elsewhere and was correct😉👍

From the workshop manual, https://manuals.wotmeworry.org.uk/Beverley/BV%20500%20E3/ , page 10:

Hello.

The manual that you posted a link to is in my closet. I have it. My concern is whether or not the torque specs on the page I posted from that manual are correct for the 5 rear wheel bolts.

The mid point of the torque range listed for those 5 bolts that connect the wheel to the brake rotor assembly is 27 pounds. This seems high to me for a steel bolt threading into aluminum. Unless there are steel nuts that the bolts are threading into which are seated in the aluminum brake rotor assembly. If that's the case then 27 Foot pounds of torque for each of those 5 rear bolts seems about right.

However, if they thread into aluminum 27ftlbs seems high to me.

it's fine, really. if you're super concerned about it back it down to the lower limit of what, 23 lb/ft?

the wheel bolts attach to the steel hub which carries the rotor anyway.

I'll do a conversion from NM to ftlbs later to find the lower limit. Thanks.

I wouldn't normally be concerned, but I'm not sure what's on the page is referring to those 5 bolts.

Also, someone told me it was 16 ftlbs, so that also confused me.

It's into steel, isn't it?

"wheel fastening screws" [33-37nm]

so, translation: wheel attaching bolts 24.3396~27.2898 ft/lb

1- never believe anybody about torque values, verify
2- never commit torque values to memory, that way you can't conflate them
(there are a very few exceptions to this rule)

interestingly enough, the GT/GTS which uses a similar arrangement and same size fastener lists the torque spec at 15~18 ft/lb. but yeah. follow the manual.
