Re: 562 Xp auto tune

One of the viewers asked a question about clearance between the transfer caps and the cases when either cutting the cylinder bases or building w/o base gasket. On mine, the flywheel side rear most corner of the transfer cap just about hits the cases. I can just get a "leaf" from a feeler gage through. On another set of cases I have it actually appears there is a wear spot EVEN though it had a base gasket therefore would need to be relieved. Is this typical? And since this would most likely effect how the transfers case to cylinder intersect... is this a potential problem and a possible reason why some are lean???

The one I cut the other day had this problem.it had to be clearances a lot to sit down flat. The case was also A tiny bit off from each half. I don't think it would have sealed gasketless.

I got just damn lucky on the one I built, going to pull it apart and measure the clearances anyway. I used a torch tip cleaner to "saw" from the back side through to the front to make certain. Actually the clutch side was fine, just the fly wheel side really close. Goo gasket has held to this point...a tank of gas! But going to yank it apart anyway.

husqvarna 562 problems

Guy working on a 562 shared this at the chainsaw repair FB group I do too.

Said he has been working on saws for 20 years at the shop. Never seen this before.

Derf on 562 carbs etc =  There was some evidence of SOME saws having problems related to heat soak causing fuel vaporization and improper metering, mostly evidences as stumbling, and bogging, difficulty starting, especially after the saw was ran recently and is still hot.
Husqvarna upgraded the el44 carb to an el46 to address the problem, though there was still SOME continuing evidence that the problem persisted.
Then Husqvarna updated the top cover with a cutout (which your saw has) under warranty, and updated the carb again in 2016 to the el48. At that point most of the problems with the 562xp hot-start/bogging disappeared.
If you haven't experienced any of these symptoms, your saw is probably fine. Having an older carb doesn't mean it's a bad saw. But some buyers are choosy about what they buy.

Wow broke that rod clean and then jammed into the cylinder like that.   That is pretty wild.

At least nothing came out of the saw and into the operator. Really got into those 562's. More going on than typically see on line with clearances though. Have to laugh when I go back and read some of the postings and issues, especially those with mods & an air leak to the transfers. Building my "Ultimate Old Man Saw" with a 555/562 blend HTSS style along with the new narrow kerf concept & light weight bar from Oregon, a Sugi will fill in until the stuff I want shows up  :)

Does it have the upgraded top cover with the extra hole for cooling? I know my 2016 550 was the first year for that upgrade.
My 2012 562 is still running strong with no issues other then hot start problems in 90 heat.

This was a answer from Bob a 40 year plus retired NY jred husky dealer. On a question by a guy on  the plastic caged bearings given up the ghost on all the folks pulp wood 562's etc. .
Also when the 562 came out with dished pistons in mid 2022.   
=  Well a few insites. And the cages aren't the actual problem. Depends on  serial numbers, and are we talking fairly new saws or 4 to 5 year old  models. There were some bad seals in Apr 20 to Apr 21. I saw it more on  550M2"s. They've made a lot of changes to the bottom ends. Even dropped  the compression with a dished piston since mid 22. Apparently they  didn't ruin it like the 262/261 deal.  🙂
Other  than the run of bad seals, the lower end issues became fairly  infrequent over the last few years. The actual seal issue was a bad lip  that could simply drop the spring into the works. It was a vendor  problem. The POSSIBLE bad seals covered almost a year, but only a small  amount were actually bad. There was just no way to know where they went.  The 550's I had a problem with were all built the same week. If they  were gonna drop, it will happen quick. Saw them go between 7 and 20  hours. After the first 4, I went and replaced them on the rest before  sale, and none of them failed.
One "advantage" of the nylon  cage, and I know I'm going to get hammered and who's going to do the  hammering, is if it goes, it melts and ends up in the muffler screen.  Very obvious when you see it there. And it doesn't take out the top end.  On a serious note, I talked to my contact in Sweden about the nylon vs  steel thing and there are real advantages to the nylon cage and why  Husky and Stihl are both using them. Lab and field testing consistently  show this. They've changed an awful lot of stuff on these bottom ends at  great cost. They wouldn't leave the nylon bearings in there if they  were the problem.
My friend the professor will no doubt join us  with a post twice as boring and 3 times as long as this one to refute  what I'm saying here. If he was the professor on Gilligan's Island, they  would have swam for it.  ::)

Gary Buxton the dished piston part I figured you would like to know it started last year mid year he says.
