Was trying to find some extra poulan 9/16 bar nuts with what seems like coarse threads today. Anyone got a lead on them or part number? I'm coming up with this 530015251 but want to make sure they are the right ones.
I always just used a 9/16" ratchet, never seen a swrench in the 9/16 or maybe I am just not paying attention. 530031146

You try flange nuts from the hardware?

Duh on me. Thanks for the idea. Local Hockler has a great selection and I can usually match up anything in the past. Totally slipped my mind.

Make sure you get the smooth faced flange nuts. Most hardware store flange nuts are serrated. They chew the hell out of a magnesium clutch cover. The Poulan (and some medium sized Homelite) nuts are 5/16-18, with a 9/16" hex. You'll probably find that most 5/16-18 flange nuts have a 1/2" hex.
As for a 9/16" scrench.......................Oregon still makes/sells them. They're labeled as being suitable for Echo and Poulan. 19mmx14mm. Part # 57-006. They're also the ticket for large frame McCulloch chainsaws, as those also used 9/16" bar nuts (but fine thread 3/8). Large frame McCullochs use 3/8-24 nuts with a 9/16" hex.

These would work fine on a Poulan...................but I think they have a 1/2" hex. That combination (5/16-18 with a 1/2" hex) was used on many medium sized Homelites.

Very Cool. Thanks for all the info.
I have a super heavy duty swrench that Al Smith made me for dolmar 166 bar nuts if anyone of you have a use for it. I have a stock one now and dont need 2. Thinking 17mm maybe?
I may have that one already. :P :P :P http://www.ebay.com/itm/Oregon-57-006-19-by-14-mm-Chain-Saw-Scrench-/321186288921?pt=LH_DefaultDomain_0&hash=item4ac831d519

Kevin, the flange nuts I bought for my 372's at the hardware above my house towards town were smooth. Couldn't tell them from Husqvarna.

I was able to take a sec and check the one I bought for the 166. It was 17mm and 19mm. So thanks for the link on the 14mm swrenches.

I change mine to 1/2....

Glenn's has a big assortment of screnches

I tried that, but the new husky bar nuts wouldnt go on the poulan bar stud threads. ??? I didnt check the thread difference of the studs, but figured something was up with that.
I just said freak it and put the 9/16 back on.

The metric thread Husky nuts won't work on the Poulan studs, despite being 1/2" hex (actually 13mm..............but that's close enough to the 12.7mm that 1/2" actually is to work with a 1/2" or 13mm scrench).
The Poulan studs are 5/16"-18.......same as Homelite E-Z/Super E-Z and XL-101 series saws. The Poulans have a 9/16" hex, while the Homelites have either a 5/8" or 1/2" hex.
5/16-18 nuts flanged (with a 1/2" hex) are relatively easy to find, although they're usually serrated. Smooth faced nuts are the way to go. Be careful to not buy locknuts. Do you have a Fastenal near you? They'll have the nuts you need.
Here's an ebay listing for the right nuts. They'll have a 1/2" hex. Most 5/16-18 flange nuts found in an ebay search are either serrated, locknuts (either stover or nylock type), extremely expensive, or a combination thereof...

McCulloch 10-series saw studs are 5/16"-24 with a 1/2" hex. They won't work on a Poulan or small stud Homelite because of the thread pitch difference.

You the man, Aaron. Thanks for the explaining. Coarse thread 18. I thought so.

This is the 3400 that I put and 'S' stud spacer, bar plates (slightly modified), and 5/16"-18 (5/8" hex) bar nuts from an early Homelite Super XL-12 onto. It's also wearing a chainbrake clutch cover that came all the way from a friend in Australia to me. Sold the saw on ebay (wish I'd kept it, but the $$$ helped last Christmas). I kept the chainbrake cover (now on my 4000), 'S' spacer, and Homelite bar nuts. Discovered that 1/2" or 9/16" hex nuts work better on the 3400-4000 Poulans as there's not much clearance between the larger 5/8" hex and the clutch cover (on the rear stud).

Same saw after being stripped of the 'keeper' stuff. The MMMM (ModifiedMark Muffler Mod) visible here. Interesting that the Homelite bar plates work fine with the addition of a slot (on the outer plate) for the adjuster peg. The Homelite has the adjuster in the bar pad, while the 3400-4000 Poulan has it in the clutch cover. A 306/245 or 361-451 Poulan could probably use the Homelite bar plates (early 5/16" stud versions that is) as-is, as their adjuster is in the bar pad. Going off on a tangent here......

You tell me the exact size I'll find some at work. 9/16" head would normally be 3/8" 16 or 24 depending on the thread pitch .

If they're Poulan bar nuts with a 9/16" hex, then they'll be 5/16"-18. Weird, but that's what Poulan did....
Kevin could of course use 5/16-18 nuts with a 1/2" hex instead.
The larger Homelite XL series studs are 3/8-16. Large frame McCulloch studs are 3/8-24.

I'm sure somebody sells those"mogul " nuts .Maybe MacMaster -Carr .We've got odd ball metric nuts hither and yon at work .Some with great big flanges for what ever reason .
Now I've made odd ball nuts and wierd bolts on the lathe and Bridgeport mill but it's a pain in the butt .An hour and a half for a 15 -25 cent nut is not my idea of a good time .Some times though ya gotta do what you gotta do .
