Husky 372XP X-torq using a 268xp piston?

[revyfaller]

Hey there, seem to find myself having some different numbers here that don't make a ton of sense to me.. Feel like I may be missing something.

Just picked up a fresh 372xp and a 268xp piston to drop in it, when I measure my squish from with the stock piston i get .038 (which seems pretty good for a stock 372). 372 piston height from top of pin @ 0.9540 and the 268 from top of pin is 0.7235. The difference between the two being 0.22 , so when i toss my cylinder back on I'd have a massive amount of squish

I will be machining the base down to make a squish of 0.20 but seems like a fairly heft amount to remove and also adjust my ports for? Or maybe its totally fine.. Figured it is worth an ask. Will be keeping by base gasket.

Is the 268xp piston only meant for pre xtorq saws?

I’m by far no expert but why not buy a Meteor piston and ring combo for around $40 and put it in your saw? That 268 piston looks like it for the strato type cylinder, .22” is a lot of material!

It's common to convert x-torque 372 s back to the original addition (oe )

You would need an OE cylinder carb and manifold.
You can only use a 2 series 50mm with the OE cylinder with machine work.
I believe they have superseded up to only one part number
for all the 50mm Jonny & husky pistons.
It's the one I like anyway.
It's a single ring Looper. (Open skirt.)

Sorry..didn't read top of page

Look it up. Tons and tons of info on this piston swap.

 

[Westboastfaller]

Try the reg chainsaw sec next time,
The single ring piston looks like a light AM piston? If so, it won't take the heat in the big wood at all.
Anyways, You need the OE cylinder.

I have looked it up, hence me saying my numbers aren't making sense to me given some of the other threads I've read. And that is why this thread exists. If you dont have any information or suggestions why bother commenting.

Our local saw shop is struggling so trying to support local! But yeah for sure 0.22 sounds a bit large haha.

Search more. You’re not getting it. Don’t make me hold your hand

I don't think you're getting it, when you use the 268 piston you need to use the older non xtorq cylinder.

 

[Ronie]

If you tying to use that piston to do away with the xtorq feature it would be easier to just remove the divider in the boot and elbow and then the top ports would carry a fuel and air mix instead of just air. They run pretty good when you do that but drink the fuel. I tried it on this one plus tightened the squish and opened up the exhaust.

Maybe I can help

WTF goes on here?

Crayons for breakfast, then a nap, a different flavor of crayola for lunch, then we learn about Husky pistons.

Welp....I got me one of dem new fangled xtra torque chainsaws....but it needs a piston. Can I use one outta a 350 Chevy?

I'm sure (you) could with the correct cylinder and a few rod spacers. I would leave off the oil ring though to reduce friction.

Mmmm I like friction.
