Oil Change Filler Bolt Allen Size

[Gutsy]

Left my bike at a friend’s place and am going there tomorrow to do an oil change.

Has anyone done their oil change themselves and do you remember if the filler bolt Allen size is 10mm or 12mm?

I’ve looked down at that bolt countless times and from memory it’s seems like 10mm, maybe 12mm.

Just want to bring the right tools for the oil change tomorrow.

Oh and the torque spec is supposedly 2Nm, which is not even hand tight!

I guess you just need to slightly compress the o-ring seal, and that’s it.

2 Nm is 1.4 ft lbs of torque. That's not right.

See above. It is 2Nm, which is barely hand tight. It’s an o-ring below, not a crush washer.

10 mm Allen

That is plenty of torque! Look at:

1. Where it is located.

2. What is it holding? It’s not the motorcycle “master bolt” .

The #1 hands-down winner of constantly overtorqued bolts are oil plugs!

They are always the undisputed king of way over tightening by owners. Please don’t be that guy.

Apologies. I thought you meant the sump plug. My mistake.

I just completed my first oil change and decided to use the oil filler port as shown above. The o-ring on the plug fits into a recess and the bolt itself has a very large landing area. I found the plug to be at an awkward angle and had to resort to a breaker bar to get it loose. I figured it must have been way over-torqued at the factory. Nope. Put it back in at the spec torque and the yellow factory marks lined up.

I found the bolt to be made of cheese, so be careful...ask me how I know . Next oil fill will be through the 'late addition to the bike' dipstick port (ON THE CENTER STAND) - much easier, and you can check the level as you go - prior to taking the bike for a 10-mile ride per the owner manual ...like a dealership does that, right!

I'd forgotten what a joy dropping the filter out from under a Guzzi was compared to a cartridge. Some things never change.

BTW the dealer did the 900 miler, at ~6,000 miles the gear shifting was not great, upshift 1>2>3 and the mega clunk was fully back N>1 (the Stelvio has had the gear box redesigned to ease shifting or so I read, so MG recognized an opportunity there it would seem). Straight downshift top to bottom - smooth. It made for an improvement, so every 5,000 miles from now on. I'm guessing this is the first modern Guzzi that combines the engine and tranny lube?

Swarf and metallic 'paste' on the magnetic drain plug. Hopefully, less the next time around.


Still lovin' it though.
