I would not be horrified if I had a Meteor 10 in a saw, but if I were choosing, with the price of OEM being so close, picking the OEM would be a no brainer.

Wonder if there is a wider pin bearing that would fit the piston better ? the rod should center itself where its happy at .

I can now get OEM cheaper than meteor so I'm happy to use the right tool for the job.

Aren't the meteor pins in a different spot ? like the 12mm locations ? I was just thinking as an option to use a later 440 jug on a 10 mm saw

I'm not saying the OEM isn't a better choice which I think it is, but the price comparison isn't apples to apples is it?
Picking up a piston at a discount from a dealer who you have a great relationship with and ordering online and paying shipping and fees don't make that a fair comparison in my head.

I need a damn head-shrinker I am starting an argument with a guy I like over something I don't give a *s-word about.
carry on

Even at retail prices, both are about the same Dave.

Found this slop in a few different saws running the old HyWay pistons before they were updated some years back. Rebuilt one that had that Meteor piston and you lose 1/3 of the bearing surface contact area with that set up. I'd bet it's fine in a stock saw tuned correctly. This saw must have done a lot of felling because the edge of the bearing cage was sharp as a razor on the pto side. The piston had excessive wear on the inner boss area of the pin wall. The Meteor piston was wore out when removed. The HyWay had the same play as the Meteor.
It's definitely a manufactures attempt to use a universal piston in 10 or 12mm.

Has anyone checked this on other pistons like the newer HyWay or other brands?

I took pics of the pistons in the same order....
and the two rod ends...

I think Brian is referring to the ring locator pins, and I think he is correct.

 

[Chainsaw Jim]

I suppose someone will be determined enough to hack up the bosses on a blown 10mm piston to use as shims to keep the rod centered when using the meteor.

If you check to price of OEM, I don't think you will bother.

Zactly my point!!

Maybe I was referring to the hamfisters who have a different idea about how to work on saws.
Here's an example....

That some funny *s-word right there! Stupid but funny.

Would it be safe to say the 15mm is only for the 12mm pin. Therefore a 10mm piston can't go on a 12mm rod cause the bearing would be loose by a 1mm.?

 

[Adirondackstihl]

Zactly......
Hence the pin size
