One more way for the 550 to die

[Stump Shot]

Had a 550xpg come back in locked up, seamed odd for the amount of use it saw.
Upon disassembly it was discovered that a tiny screw had found its way into the cylinder.
You can see it as I found it in this picture.


It took a little bit of detective work to find where it came from.


I believe that a drop of loctite will be standard procedure for these two screws in the future.

Somewhat fortunately, this cylinder is not badly damaged, a little bit of beveling, a new piston and screw and it will be back in business.
This is not to say that it could not have turned out worse and the cylinder could have been ruined, which is a much more costly proposition.

what piston options are out there for the 550 these days steve? the only time i bought one, it was actually $5 cheaper for the whole top end kit than it was for just the piston from husky

Meteor actually makes a nice replacement for the mark I atleast $35-40

Screws falling out of a Husqvarna, say it aint so...

well, technically it didnt fall out of the saw, it just moved to a more secure location...

I noticed that LilRedBarn have started to sell their branded popup piston for this. I have never used anything other than OEM in this series of saw.

What year is stamped on that 550?

quality control was pretty bad from what i understand and experienced during certain years.
I never did understand why a pro saw meant to replace the legendary 350 had the car made in china by zama...
Should have been the first red flag of many.
I know there are many 550 owners that have great unproblematic saws, however i was not one of them...

Fell out of position, that good? Can`t see what it is securing cept ruining a piston, oh the irony of it all...LOL

Prices on cylinders went up if that makes it any better.

I went with the Meteor.

I always use loctite for fasteners clamping on plastic/composites without a metal sleeve to take the load, if they aren’t often removed cover plastics anyway, i’m surprised more don’t fall out.

I do like to hear from more experienced saw builders to find out which models and what screws have a habit of coming loose.

Husky quality.

IMHO, they just can’t compare to the Ergonomics, QC and elegance of Stihl.

Sorry guys, Stihl just produces a superior product. After the “2” series, the Husky seemed to get cheaper and cheaper feeling.

Same for me, I just stopped all repair work on them by mid run of the 3 series. I dislike having returns for fasteners falling/rattling out. The 2 series saws seemed better built but even they lost fasteners unless Locktite was used.

No

Oh, now I see, its securing the piston. Must not allow that piston to move, that would be noisy.

Swing and a miss?

Don’t like loctite?

No, I was saying you teed it up for the Stihl honks.

They all have their issues, even Stihl, which can't seem to keep a simple bucking spike attached for example, do I need to go on here?

Point of this thread was to hopefully save someone ruining a cylinder, especially a ported one, because of the possibility of a simple fastener malfunction, as it was something new(to me at least) not fuel a fanboy frenzy.
