Rebuilding a 576XP - for a rookie
« on: July 18, 2014, 08:48:21 pm »
Hi, folks.  One of your members invited me to this forum, and I'm glad he did.  There's obviously a wealth of info here, and I see an old friend, SawTroll, is hanging around!  Hi, Nikko!

A few years back I bought a 576XP from a member of another forum.  He had bought it to experiment on, I guess. He modded it (muffler & ports) and it never ran right.  At first, it would shut off after only about 10 minutes. The choke lever would pop out, it would shut down, and it made a sound like it was boiling.  I'd have to let it sit quite a while before firing it up again.

After a few tanks, it started running decently, and I've enjoyed using it.  A couple of weeks ago, I pushed it too hard on a dull chain (stupid stupid stupid!) and toasted it. 

Looking through the exhaust port I can see it's got smeared rings, and I don't know about the jug at this point.  The piston does still move okay, though.  My local Husky dealer first quoted me $475 to fix it, then said it was "unrepairable".  All that from looking in the exhaust port!

I've never rebuilt a saw before, but I want to tackle this. 

So, recommendations?  Is this something a rookie can handle?  I know I'll need a few special tools.  I've seen a decent Youtube video on rebuilding a 372.   Is this saw similar enough that I can use that as a guide?

At this point, even if the jug is okay, I want to replace it.  I want to get rid of the amateur porting job and return it to stock.  The muffler mod... I dunno, what do you think?  Leave that alone?  Or will it not play nicely with the stock ports?

Whatcha tink?

Welcome to the site.  I have never worked on the 576. But would rebuild one if in your situation. 

There is some tips on them and their intake issues etc here somewhere.

If the cylinder will clean up, big savings. Good cylinder how to clean up in another board.

Re-build it! (piston/cylinder) and don't monkey with the ports. Should be a relatively easy job swap a new top end.  Think about spending a few more dollars and replacing the crankshaft seals while it's apart, or pressure/vacuum test the lower end.  Adam

Rebuild it.   Just make sure to pay attention to detail when you take it apart.   I sometimes take pictures with my phone  so if need be I can reference back to them.   One example would be which direction the pin for the ring in the piston is facing.

+1 on what 3000FPS said. Pay attention to detail! On/off/choke linkage is frustrating if you just rip it apart. Get yourself the WM for the saw and have a close look at it. Seals are not expensive and are cheap insurance.

Your dealer may have been concerned about the labor factor in his 'unrepairable' comment as the 570/575/576 are sort of a PITA to work on.

Take your time and follow the manual and make sure you know if your saw is the AT version or the standard version. The muffler is an empty tin can, you could reuse it but a modified muffler requires that you adjust the tune for it, usually you will need to go a little richer on the tune. Run 32:1 mix.

Where are you, perhaps there is a member close to you that can help you along. OH, and follow what AClarke said and as Cut4Fun said do not mess with AM on the C/P get the OEM kit from HLS. The AM kits are OK but no where near the quality of OEM. Did a 576 for another member here a short while back, I used the OEM kit from HLS and was very pleased with the results.

I see folks doing this all the time with their firewood saws. Touch up the  chain or carry spares.  I just dont get why folks run dull chains and force them in the cuts.

Last one in for repairs was a guy forcing a dull chain in his final cuts for the day.  Well he didnt get  to finish them till he got out the other saw.

I don't understand it either Kevin! If you want to force steel through wood, buy an axe!

Just fininshed a topend on a real nice 266.  Cooked the piston leaning on a dull chain.  Customer said his son did it didn't want to stop and sharpen chain.
