yep, right through the fill hole with a piece of wire, then pull it in with a bar nut and washers. nothing to it

You can dimple the stud and around the case bore with a center punch and push it back in with some loctite.

you then needed to use a stihl bar correct?

Yes. It’s was the 12mm studs best I remember. Could have been the 14mm

The one I did drilling and tapping was so big a 056 stud wouldn’t fit. I didn’t want to have the case half welded so I drilled and tapped it together. Rinsed with pure gas for a while to get it clean.

Check the case around the hole for a crack. These saws are famous for it.

Pull both bar studs then find a suitable cradle to lay the stud in and stipple it all around with a center punch in the area that is in the mag only, If only one is loose do just the one.
Take a good flat file or a flat item with sand paper on it and flatten out the bar pad until it's trued.
Clean the studs and holes and install with a ample supply of red Loctite making sure the stippled stud goes back in the wallered hole, also check the clutch cover it may need to flattened out as well.
Now it doesn't need 500 foot pounds of torque to hold the bar as it is nice and flat and will hold back bar oil as it's making a good seal by the oil passageway.
