Title: 45mm Piston for closed port cyl
Post by: farmboy on January 04, 2015, 05:01:59 pm

Thats one of the ones I ask about in other thread. Nobody tried it or just dont know.  You feeling guinea? 

I am thinking I ask a seller and maybe it was wrong pin size or something. Dont remember try asking them first.

Likely a spare for the really crappy Chinese "5200" saws - so likely not a high quality part?

I PM'd him 2 times he won't tell me the pin size.  Not buying it to find out

Would you trust the clips and the ring in that kit?

Never had one of those so couldnt tell yea.  For one I wouldnt use double ear aftermarket clips.  Only OEM ones

I am testing some now no name aftermarket. So far so good in my own saws single ear clips. But IMO saw your care about get caber rings and if oem circlips fit good use them. If wont fit right circlips trim the tails off to be safe.

Is the pin size the same as the husky? I couldnt find any specs on the lilredbarn piston.

Thanks for the specs. Thats half the battle. My 55 CP box o saw that is on its way to me has no piston with it to measure for comparison :-\

If you had a complete saw minus the piston . . .

You might surprise yourself on your ability to develop the dimensions of the piston needed as to bore, compression height, skirt length, skirt width, piston pin boss width, and pin diameter? Most of this you can see as imprinted wear patterns on the used cylinder and a quick measurement of the rod? Most of this can be achieved with the wife's cloth dress measuring tape.

Was husky marking the top of oem cylinders on these like other cylinders?

You need to measure your bore to see what you have?  You say closed port? Your sure CP and 45mm then?  If so you might be able to just clean up cylinder and use that jonsered 535 45mm  piston.


That 46mm piston in those kits are.


Bore 45.93mm
Height 37mm
Head Type Flat
Piston Pin 10mm x 34mm x 6mm
Ring 46mm x 1.5mm Caber
Compression/Pin Top to top of Piston 14mm
Compression/Pin Center to top of Piston 19mm

It hasnt made it to me yet. Hopefully it will make it here in time for the Blizzard.  :o The previous owner send me photos of it including some of the cylinder. First thing I will do is measure it. It sure looks like the CP version. I am hoping that maybe I can clean up the cylinder and use the 535 piston. I was just hoping to get the actual dimensions of the CP 55 piston to compare against the 535 piston. THey sure look the same but I havent seen anyone confirm that the the critical dimensions like the overall height and dimension from the pin to top is the same as the 535. Maybe I missed it. It is putting me at a disadvantage having the previous owner already toss the piston. What does this cylinder look like to you all?

I'm sure the 55 590 piston 45mm specs are here somewhere.

I know mweba has said he used the jonsered 535 piston even in the 45mm husky 353 etc.
Title: Re: 45mm Piston for closed port cyl
Post by: Cut4fun . on January 25, 2015, 07:35:05 pm
jonsered 590 also 55 CP used piston I had but never measured and entered specs as far as I can tell.

Anyone got specs on a stock 590 55CP piston?   We got Mitch's 535 piston specs already.

I've been searching the net but cant find anything for specs. They sure do look similar.

Copied from other places:
Jonsered 535 piston specs:

35.4mm tall
 pin height 13.8
 skirt 29.66
 wrist width 10.52
 pin 10mm

Husqvarna 55 closed port piston specs:

Compression Height = 19mm
 Total Height = 37mm
 Width between pin bosses -=14.75mm
 Pin Diameter = 10mm

Doesn't look close enough for a direct out of the box replacement.

That was my observation looking at the Meteor 45mm piston dimensions.

Now I wonder what the specs are on the aftermarket jred 535 piston. ;)

Finally found where a few of us talked about these last year or 2.  11mm pin for the chinese 5200 piston

I havent figured you out yet, Cut4fun. I keep getting the feeling you are ten steps ahead of me when you give the wink.  ;)    ;D

Post by: Cut4fun . on January 26, 2015, 08:30:50 pm
Nope just wondering.   ;)

I got out of these model saws long ago.  5000, 5000+, 500, 500 45mm one too, 490, 590, 55, 325 etc.
