I've had some time to study these saws in the last couple days. Yesterday a couple of us got together to run my old 555 against the 562 in some hard wood. Got some video and noted some differences.
Include but not limited to....
Rear antivibe has a nylon limiting strap
top cover obviously has more clearance for the larger filter (both are interchangeable between saws)
562 clutch cover is "taller" to accomodate the large mount bar
Cylinder casting and part number are the same but the transfer caps on the 562 cylinder are visibly deeper
562 has crank stuffer
Ignition part number is different but I have my suspicions the the flashed software is the only difference....(hopefully the diagnostics tool is capable of flashing)
The 562 holds near 1k more rpm in the cut with similar pressure applied.
This may or may not be everything but a good start.

O ya and the paint LOL
-
The transfer covers are not available separately
-
Nope but I don't think it would be difficult to replicate. Mdavelee has some ideas
-
Here's a couple pictures of the transfer cover. That would be a lot of mill work?

Was thinking about adding material then grinding a bit???
I'm terribly unskilled so I'll probably just grab every straight gasses cylinder the local shops get ;D Or just lazy
-
Yes,
I had to go do a chore but was thinking one could take a 555 transfer cover and make it deeper by cutting a grove in it and attaching a new cover piece over the original 555 transfer.
If there is too much zinc in the metal to weld, and you may not be able to weld it anyway for the new part would be a different aluminum alloy, the new cap would have to be JBweld attached? There is not a tremendous amount of heat there
-
Nice mweba.
Just so we could save them from the ebay ad. We have a thread here some where with the 562 stripped all the way down.

I was thinking of doing it by hand and then having it finished at a machine shop. I would imagine it could be done it a few hours with basic air or electric grinders. Getting the mating surface perfectly flat and the groove put in it for sealing would be the parts I would have to farm out.
-
IMHO the difference between the 555 and the 562 is the depth of the transfer cover if the cylinders have the same casting number.
It would be more simple to hand grind a hole down through the top of the 555 cover and JBWeld or aluminum solder a new piece of aluminum on top of the 555 transfer cover to make it deeper by the thickness of the metal in the cover. It could all be done by hand and not require any machine shop work?
It is such an irregular shape that even the machine shop would have to do much of it by hand.
The cover will have so much zinc in the metal that it will be impossible to actually weld on it?
When there is a lot of zinc in an aluminum die casting such as these covers and you try to weld it, as it gets up to temperature for the metal to join, the whole part will suddenly disappear into a puddle of molten metal.
If you get into making those groves for the gasket when making a entirely new part, it would be an impossible task.
One might could utilize old covers from a trashed 562 cylinder on a new 555 cylinder?
-
Did you guys notice the rev boost on the 562 compared to the 555 not having that feature?
-
I went back and listened several times and it happens pretty quick. Almost like an old analog tachometer needle over running the actual rpm. It doesn't stay up there at the highest rpm but a second.
-
The 555 does not rev as high or fast. That is all I can say for a fact. I need to get the diagnostic tool on order.

Pictures of 562XP cylinder/piston on the left and 555 cylinder/piston on the right. Notice the difference in the height of the Transfer covers.

While it has been discussed elsewhere that it is not cost effective to buy a new 555 and convert it into a 562XP . . . .
It is cost effective if you have a used 555 that has to have the bearings replaced and the case has to be split anyway. Then you may as well add the full circle crank pieces and transfers from a trashed 562 cylinder.

It is not cost effective on new saws - looks like there are more differences than what was known earlier. It has happened before that the replaccement parts show in the IPLs are the same, while the originals are different! ;)

The 562xp sure mods well. I can't believe how well the autotune compensates.

You got anything to add to this thread? http://chainsawrepair.createaforum.com/husqvarna/560xp562xp-have-a-outboard-clutch/90/

Well, i pulled the trigger on one today. Quite anxious to see how she compares to the 555 I had. I believe she will outshine her. As she should. As advertised. 8)

I just finished welding the muffler back together on another one. These saws are hot right now. I wish I had ten sitting on the shelf. :)
-
If I were a betting man, I would bet we aint seen nothin yet. As far as Husqvarna is concerened........ ;D
-
They really are hot right now Randy. I just couldnt help myself. So many good things said about them, its really hard not to get one.
-
Ok guys, I got my 562xp last night. i will run her some Monday. Cant wait. Im sure the difference between her and the 555 will be somewhat noticeable. How much? I cant wait to find out. btw, I also scored a great lookin 562xp tee shirt as well! 8)
-
Only thing I have been told is run the crap out of her right off the start which I did mine and I'm very happy with the 562 , never ran a 555 but I'm sure they are a great saw as well
-
Thank you sir. Thats exactly what I plan to do.
-
Dang Mitch put a 36" on here.

Well.....it was hangin on the wall and I was like....I should try that LOL. Being a 36 has NO place on a 60cc saw, it did ok IMO.
I can't say enough about this saw. From the build quality to the thought out design, they just nailed it. What I'm curious about, will the throttle response of the 346 replacement slow our planetary rotation! I mean these 562's rev like a 346 and pull like a well broke in 365.

How did the oiler do on the 36''er?
-
I think it was falling behind but I didn't run it much more than in the video. A 32 would be fine with good oil.
-
LOL, thats incredible. A 32" would be fine on a 562xp. Damn glad I got one. Yee haa! ;D
-
Never thought I'd see a 60cc saw pulling a 36" bar pretty easily it looked like.
