That's 46mm, our 55 closed port rancher was a 45mm.Here is a new closed port piston, http://www.hlsproparts.com/Husqvarna-55-55-Rancher-windowed-piston-kit-p/h31055-w.htm. .

I thought the 45mm piston was for a 51. I have a 98 model I used the 46mm piston in. I think I still have the old piston, if I find it I will measure.That's 46mm, our 55 closed port rancher was a 45mm.
Converting a closed port 55 to open port seems like a step in the wrong direction. I would try the lil red barn piston before I went to an open port saw.Could always go 46mm but i havnt really found how well these kits work on our saws. If they had good fit and acceptable squish i might consider one.
That very well could be. I acquired it by way of another member (on here) who picked up a "roached" saw for me because we needed a tank. After purchasing, he realized it was a closed port cyl. It was a 55 rancher but I have no idea if the cyl was original to the saw, we assumed it was.I thought the 45mm piston was for a 51. I have a 98 model I used the 46mm piston in..
The hijack is fine by me, you guys posting some interesting stuff. And the hyway kit i found was a 46mm closed port. But im planning on cleaning my pistion up and reusing it and just slap a new ring on and getting the cylinder cleaned up also of course.Converting a closed port 55 to open port seems like a step in the wrong direction.

Now that we have effectively hijacked the OPs thread....I apologize and how is your 55 closed port coming along ? I hope the info so far has been helpful in your rebuild.
No need for a decomp and they are known to fail causing a lean condition, I'd plug it.I thought the ranchers were all open port saws? Is there a definitive way to tell, without pulling the jug?
Also I recently put a Hutzl/Farmertec 46mm kit on my grandpas old model 50. Got all the gaskets, seals and ordered a new oil pump and muffler too......all seemed to be good quality. Definitely far better quality than I expected for the approximately $40 I had in the whole thing. Jug was even tapped for a de-comp so I added that too. I did a little porting and deleted the gasket......seemed to run good.
Best way to measure piston fit is put it in the cylinder without rings and measure the clearance between the cylinder and skirt of the piston. If memory serves it should be around .003 ", maybe a little more. Someone with more experience will chime in I'm sure.View attachment 552575 View attachment 552576 dont know why the one of the piston is upside down. Im sure there is a better way to measure the cylinder but i dont have a bore guage.
Me too, for the 50, 51, 55 and 61 ranchers at least.I thought the ranchers were all open port saws?
