Husqvarna 576 Repair Thread.

@RI Chevy
Joe, I was just "searching" your threads looking for a 550xp one so I could "motivate" me to attempt muh fust Husky redo.
I think this might be just good enough to get me started. (Have I mentioned the "search" function here is befuddling ? Cumbersome ? only slightly effective...but that's another subject.)

I did do a few husky 455's a few weeks ago and NOW I think I am starting to "speak" husky repair. So far the toughest thing for me to "handle" was...the "handle"...almost every repair requires the handle removed...but that is so easy even a "Stihl" guy can do it. I almost never remove the tank/handle on a Stihl because its a Biatch....Not so on a husky....

SO....im a gonna try me a few Husky redos ( wish me luck) ....I been refusing to speak "husky" for years....but im opening up to new things as I get older and the stubbornness seems to fade.

Just don't tell Jeff @RI Chevy

Now for the most important stuff.... Check yer phone...I texted you a few days ago....

Don't go to the dark side! Lol

Now onto the intake, as previously stated this is a Strato saw so there are two throttle butterflies, one for the charge and one for the clean air that purges the exhaust. That being said it is really no more complicated than an ordinary saw.

A look down the barrel.

To disconnect the throttle start by depressing the trigger.

The throttle arm will pull back like so.

Hold it open and release the trigger.

The carb box will coax a few swear words the first time you do it on husky autotune, but once you do it once it’s actually pretty easy. Order of assembly is key. Walt has a good video series I learned from (562 is just the big brother to 550).

Joe, how long does a repair like this take you? Just out of curiosity. Not counting all the picture taking, obviously. Great thread, by the way.

Four hours start to finish but only two are billable, the other two are cleaning.

This thread isn't even half finished at this point, I still have the entire re-assembly. Just ran out if time yesterday because I was hosting a Fourth of July party and I got busy in the kitchen. More to come, stay tuned.

One thing I would suggest before starting a AT Husky. Is get the Vac/pressure test block off kit for them. It make life so much simpler to check them before and afterwards.
Case splitter and crank tools are very handy but not completely needed........but the price on all of that stuff has come down so much its kinda a nobrainer now for me.

There have only been two saws I've sold that I regret selling, a 7910 and a uber mint 576 AT...grrr

 

[1Pitbullman]

What bearings did you use? What caused Saw to fail?

 

[Onan18]

What bearings did you use? What caused Saw to fail?

Husqvarna OEM bearings, pretty much the only option as they are proprietary. Saw died due to age and neglect, there were several things that could have caused it so a full rebuild was the safest option.

Thanks . I have a 570. Was going to rebearing and go through it.

 

[1Pitbullman]

Do you mind listing part numbers for items you used?

 

[1Pitbullman]

By the way, Awesome thread!!! I like your photos and descriptions!

 

[Onan18]

Alright, back to reassembly, as previously stated the @Mattyo crank took kit does an excellent job.


Well, it is a Husky...


Run the case screws in and tighten them down in a cross pattern.


Seat the crank seal in, the PTO side seal is made into the bearing.


Next set the carb floor in.


And install the screws.

 

[RI Chevy]

I like the thread locker! LOL

 

[Onan18]

Now drop the oil lines back in and set the oiler back in place.


The screws that hold the oil pump on need sealant on the threads as the holes go all the way through into the crankcase.


Lay the wires back into place.


Drop the flywheel back on and seat it on the taper.


And tighten the nut down.

 

[Onan18]

New parts.


For reference.


Oil up the piston pin bearing and slip it into the rod. Now is also a good time to lay the base gasket in place.


Set the piston on and push the piston pin through.


And seat the circlip.

 

[Onan18]

Let's start prepping the cylinder...


First things first, no factory air leak.


Next screw the A/V mount on.


Here is how the intake side of the cylinder looks. Like most newer model Husqvarna saws the boot bolts on with a flange, in this case with three screws.
