Bottom of the 661 line.

How ‘bout that?

Ok fellers , I ran one tank thru the 500i yesterday using this converted light bar and a Stihl 10 tooth .404 tip identical to @ferris setup and got the same results. For some reason the sprocket doesn’t support the chain Long Enough. View attachment 357835
Or maybe the tip is made a little wide/tall at that point for some reason.

I think the Tip is too narrow, the 3002 version is wider. Also the old 3003 bars are wider. So I think it is normal

@Brewz @deye223
What are ur results with 3003 404 bars?

That's a design stuff up on Stihl out of the box probably a recall if they knew about it. Most likely the guy putting pins in oil pumps has been moved onto designing bar tips lol

That’s funny

From tip, to bar mount. Defective heat treating and inferior/soft metal in recent stihl-born .404 bars.

Stihl is the mechanical equivalent of AIDS, it left the factory with HIV.

I've been having better luck with tsumura and GB bars in the millers:

Smiling. Gawd I enjoy all-original, stihl-jokes.

Stihl ruined their hard nose bars as well the radius is all wrong on the new bars.


This is one of the good old school Stihl hard nose bars.

That rascal’s got some meat left on it. Hardly looks used.

I didn’t realize the Stihl and Echo shared the same mount. I will look more closely at mine. I don’t know exactly why, but I’d have a problem leaving my 1201 outside long enough to accumulate that much snow. Lol.

The older milled bars are by far the toughest steel that ever was ,but Gawd awful heavy.

 

[rogue60]

I think we've have talked about them before they are the newer reduced kickback hardnose bars they are crap.
This is them



Oregon still make a good hardnose bar

what are you cutting? do you do a lot of limbing and just smack the tip into the limbs. i have seen bar with wear like that from limbing all day and continuious pounding in the same spot production limbing as a chaser

The cuts I was making were just cookies thru about 20” maple. Very smooth deliberate cuts, start to finish w/o interruption.
I have some real old bars that I’ve used the heck out of (.404) that do not display this wear. They all have a much larger tip radius and the small radius along with maybe trying to save $ on materials I think could be responsible for this .

 

[pbillyi69]

odd for sure.

 

[av8or3]

Here’s an odd one. This bar came with another saw and I never forsaw a use for it until tonight. It’s stamped .404 and the groove is .050. Well, Jimbo just happens to have some .404 in .050 gage. Can’t wait to try it out. The tip on this bar looks like 3/8” was run on it at some time.

 

[av8or3]

Here’s a pic of the nose on this GB bar. The links don’t even touch the rails. The rails were over heated when someone ran 3/8” on it, I think. The drive links in 3/8 won’t reach the roller under there so it had to ride the rails and they are not Stelite. Anyway, looks like the .404 rides the roller fine. It’s a smooth roller, no teeth, that could be why folks think it’s ok to run any gage. But the bar is stamped .404 because the roller location and nose profile.
But you gotta admit, it’s weird to find a Modern bar manufactured for .050 .404.
Maybe it’s not so scarce down under.
