File a little off the top and bottom of the studs until the small bar fits. If at some time you need the wider slot bar just turn the studs a quarter turn.

Anyone know for sure the thread pitch and diameter of the stud end that threads into the case?
Be a cool coincidence if they were the same as Stihl D025 studs- replace original studs with Stihl ones and run Stihl bars forevermore!

Is there sone reason you don't want to file the bar slot on an 009 bar out to 10mm?I've done this numerous times and it works fine; takes 10-15 minutes and it's a done deal.

The 910E had to have had the WORST throttle handle design known to man. What were those engineers thinking? Less weight or less brainpower?
You learned fast using them that if the bar got pinched, you NEVER pulled hard with the throttle handle. Jonsereds did sell a kit that strengthened the throttle handle A/V's. I have the kit but haven't installed it yet.The 910E had to have had the WORST throttle handle design known to man. What were those engineers thinking? Less weight or less brainpower?
What I laugh at is the wrap assembly. The standard wrap is incredibly over-complicated and yet replacing with the full-wrap deletes a lot of the fittings. It's was a classic case of like what Stihl does even today;having a good system, but trying to make it 'better'.
And then on the 920/930 they overcompensated with those brute clunky Partner wraps and handles.

No reason other that making sure the oil holes line up perfectly and you took the same amount off of both sides. The Carlton bar I did was no 10-15 minute job.
And doing that every time for a new bar doesn't make sense when you can have the bar studs made just once.

Not to mention that you can't find the anti-vibe mounts anywhere!
It’s beginning to look like my option for a new bar might require a little input! Has anyone got suggestions for a new bar that will require modifications? Anyone actually done it? How about a preferred brand name (other than Jonsereds) that someone has successfully modified? I’m looking for a 28” bar, 0.58 gauge 93dl and there seems to be lots of choices out there! Still…someone might have knowledge of one brand that fits better or is more easily modified than the others so that’s what I’m asking about. As with everything else in life, you don’t know till you ask, so that’s what I’m doing!
Tsumura makes a 24" 058 bar for 10mm studs.
I do know of someone that is capable of machining up new studs and I have an extra set of the 10mm studs I purchased on eBay that would give this guy an idea of what I want. However the first thing this guy will ask me is what pitch thread do I want for the 9 mm setup? Does anyone know the actual thread sizes for the D009 9mm studs? I know the thread size for the end that threads into the case but what about the size that fits through the guide bar? Are these threads standard or metric and although this guy can probably machine up any size I would rather he make them the exact thread that the factory version would’ve been?

The threads on a D009 stud are not 9mm thread- they are 8mm- standard metric 8 X 1.25.
I picked up a set of Jonsereds 820 bar studs on eBay and the thread size going into the case is 10mm x 1.5 however I also got a bolt 8mm x 1.25 to check the size of the D009 you suggested was the thread and it seems pretty small in comparison?Anyone know for sure the thread pitch and diameter of the stud end that threads into the case?

the 8mm x 1.25 pitch seems kinda loose? I picked up an 8mm x 1.25 bolt and it sure seems like there’s lots of play in comparison to the guide bar slot. Since these are machined studs isn’t it possible they could’ve used an M9 x 1.25 thread?

The threads on a D009 stud are 8 X 1.25- but where the bar sits it is not threaded and is stepped out to suit the bar tail slots.
An 8mm bolt is constant diameter- but I am not sure what you are screwing it into here? If you are threading a standard 8mm bolt into the stud hole of a Jonsered 820 case- then yes it is going to feel loose because they are not the correct match,.
The bolt was just an example of the thread I wanted on one side. I was going to take it to the machinist so he could understand what I’m asking him to do. I have two 10mm studs I can use as a general length/guide so he’ll understand what I want the machined studs to look like.
Are there any Husky 9mm studs that would work?
So, same as the Stihl 056 studs…?
or, what they sell now as an oversized for when the 8mm rips out.
