So for the people on here that are more chainsaw savvy than me. My dad got a saw from a guy that blew the engine on a Husqvarna 575xp. It was in the garage when I went home this last weekend and I guess it is ours. My dad was thinking of parting it out but that probably wont happen and it will just sit in the garage so I told him I plan on rebuilding it.

It is a newer model from what I can tell that looks more like this:

Husqvarna 575xp

My main questions are will it be that difficult to rebuild (I am not much on a gear/engine head).

Is it worth the money to rebuild

My grandpa is great with small engines and has all the tools to fix them so his help is available.

So any help I can get will be great.

Thanks in advance

Casey
 
Re: Husqvarna 575xp Rebuild

I think you'll find that it's not as difficult as you may think. I recently rebuilt a Stihl MS 290 that I got the same way as your dad. It is what they call a "clam-shell" type design and supposed to be harder to work on than a pro model saw. I tore it down and put in a larger piston and cylinder and it runs like a champ now. Not that hard. The main thing I did was keep all my parts-screws, washers, etc. in one location all together so that it was all there when I put it back together. I'm not sure what a new 575 runs, but you can rebuild it for a fraction of buying a new one. If it was a lean seizure from having straight gas run through it, then put a new piston and cylinder on it and be done with it. You can look at Bailey's, ebay, local saw shops and compare prices. Being that saw is a pro model, you can probably get by without tearing it completely apart as well. Pay attention to what you're doing and put it back together just like you took it apart. I found that my experience was a great learning one, and have begun to play with a few other saws. Once I got my rebuild back together, I took it to the saw shop and had my gut tune the carb with a tach to make sure it was running right. Sorry for the long post, I hope it helps.
 
Re: Husqvarna 575xp Rebuild

No that helps a lot. I hope more people can chime in about the saw itself because from what I am gathering it was a 1 or 2 year saw
 
Re: Husqvarna 575xp Rebuild

I have a friend with the same saw that was also seized up and then freed. It runs, but not very well. If I remember correctly, the parts to rebuild the top end were somewhere in the $500 range. I think the saw is around $800 new. Hope this helps.
 
Re: Husqvarna 575xp Rebuild

Yea I have been finding mixed reviews on the saw. I will tear it apart none the less to see what the problem is first
 
Re: Husqvarna 575xp Rebuild

Here are a few piston and cylinder kits that I found just doing quick search. I'm not sure which if any is better than the other. I went as cheap as I could on my rebuild as it was mainly for a learning experience. Hopefully this will get ya in the right direction. Good luck and keep us posted.

What does a generator in a saw do?

So started to tear down the saw and realized that the piston and cylinder are not locked up. What actually happened was on the flywheel side of the saw on the inside of the flywheel there is a thing called a generator on the inside. What happened is that the screws that held down this generator came loose got up into the flywheel and eventually stopped the saw.

So my questions are what does this "generator" really do because I never seen this in a saw before?

Other saws that I have torn apart don't have this extra piece inside the flywheel so is it just for extra power?

Thanks in advance for the help.
 
Re: What does a generator in a saw do?

Ok cool thanks,

could you elaborate on how it does this for a saw that has one and one that doesn't?

I mean it has to do with magnets and such but does one with the generator produce a stronger spark or anything?

Sorry if these are stupid questions...i am not very mechanically smart
 
Re: What does a generator in a saw do?

Take pictures before you remove anything.

Get a piece of hard foam and a fiber tip marker. When you remove a component put all of the fasteners together is some sort of pattern or order. Use the foam to hold the pieces. Sometimes you'll need a knife or screwdriver to poke a hole first.

With some googling you might even find a line drawing of the exploded view.

If the magneto/coil moved the mounting screws may have stripped or been damage. Locktite makes all sorts of products to help you out there.

Old cupcake baking pans from the thrift store are a mechanics best friend. label the trays 1-12 with a marker. Put the removed parts in the cups in order and then reinstall them in reverse order. Saves an awful lot of head scratching.
 
Re: What does a generator in a saw do?

Casey,
One of the most important things in a repair or rebuild is to identify the cause of the failure and correct that so your efforts and expense are not in vein. for example if it was a lean condition siezure and you put a new cylinder and a piston and ring set in, lets say $500, and did not know the failure was due to worn crank seals or say a vacuum leak at the intake causing a lean condition the motor will fail again. Now you would have to spend $500 again-ouch! Had you identified the cause and replaced the worn crank seals after inspecting the crank for wear and so on... you might have spent $10-20 more up front but would have a good saw with a long usable life.
Hope that helps you in your approach to repairing your saw.

So why did the stator come loose? thats the question you want to ask and make sure it doesn't happen again.

Best

Bought a 390 XP off a guy who said it was blown up and Screw was caught in the flywheel stopping it from turning. Score!!
