550xp Here we go again.

[Andyshine77]

Well was running my 550xp last week, and boy I've had some bad luck with these new Husqvarna saws. She started fine, but soon started running totally erratic, wouldn't idle started running lean you name it. Well I knew I have a model with a serial number that had a run of bad transfer seals, so I figured that would be the problem. However I didn't get that far when I found this.

That's a nice ding from the factory.

 

[Big_Wood]

it was you!, you assembled it wrong! we know you strip it down to check for scoring after every run. look at those wires. can still tell what colour they are. **** that thing might have half a tank on it!

Totally incorrect you ass, it has two tanks run through it[emoji8]

Seriously though I have been afraid to run the stupid thing, wonder why? Lol.

One of the transfer seals doesn't look great, but I believe a little sealant will take care of it, the other seal looks acceptable.

Is the saw still under warranty Andre pretty grim if it is

Well right after I bought the saw I wasn't really able to do much cutting so she was sitting for some time, that and I have too many saws lol. Anyway it's out of warranty, but I'm not too worried I'm, sure something can be worked out, as this is obviously a factory defect.

I inserted the strato port back into the boot, it may or may not seal, as it's deformed. Looks like all I need is a new boot.

The quality of the cylinder is quite good, but I can't say the same about the transfer covers or seals themselves.

Andre, are the transfer seals just a piece of Oring (round cross section) cord cut and placed into a groove or is is something more fancy?.....By the looks of it there isn't even a groove to captivate it.

The covers have the groove to hold it in place. It's a molded seal, not sure if you could find a ring the exact size or not, I doubt that would work. Very cheesy design.

 

[Jeffkrib]

Someone needs to make an after market high temperature moulded silicone replacement seal for this disgrace.......
I may have to pull mine apart model it up, jump on the CNC and mould a batch of 1000 units myself.

 

[Andyshine77]

Make some quality transfer covers while you're at it. Check out the corner of this cover, is has a kink in it, and the corner of the seal is exposed to the screw. Again I don't think it's going to leak with some sealant. The cover was so deformed it bent when the screw was tightened.

No offense Andre, but I'm glad I sold my 550xp in favor of my 346XP NE, guess I'm just not a fan of the auto tune saws....

 

[Andyshine77]

No offense taken, the 346 is my favorite 50cc saw...

Keep in mind that it has nothing to do with AutoTune though - this is a basic quality control problem, along with a questionable design on that cover casting and seal. Then compounded by the stupid decision not to sell those cover seals.

 

[blsnelling]

Grrrr. Frustrating I'm sure. It's in good hands though

 

[Andyshine77]

A bit amusing actually.

Did you have fun funding the little plastic clip on the bottom of the carb?!

You know I found it pretty quick, and a little orange screwdriver did the trick. It took some force to bend that tube in like that, I really don't know how someone could do that without knowing something wasn't right.

To me it is clear the saw was never vacuum tested at the factory, it never could have passed a vac/pressure test.

Going to do any port work while your in there?

I figured I might as well.
