Title: Jonsered 590
Post by: Cut4fun on February 27, 2011, 12:10:02 pm
Here is my start to a 590 project.

 Just so you can see what a 590 looks like inside.  I really like the set up on it.

Thanks (also for telling me about this site)!

Did you measure the bore of it?

This site looks really promising!   ;D

45mm bore and I think that makes it 50.7or8cc

45mm bore and I think that makes it 50.7or8cc

45mm fits with the info I have from before - but I believe it is 50.9cc, maybe 50.8 (seen both numbers), but not 50.7.

The exact cc is an "academic" question, I just wanted to get confirmation that it wasn't the same 46mm/53.2cc as the P5500.  ;D

Poulan 325 is 46mm and I got one.  The top end fits on the 490 590 5000 500 50 special to if one so desired a cheater saw.

Me either anymore and post wasnt about racing, but the term I used was. Sorry about that confusion.
But what I was referring to, is you could bolt a PP 325 top 53cc on the 490 5000 500 50 special and gain a great deal of torque in the cut for a firewood saw with the same weight of the 49cc saw.

Crappy cell phone pics.

so you would call the 590 a open port with a windowed piston? ???
Title: Re: Jonsered 590
Post by: Cut4fun . on March 12, 2011, 07:40:33 pm
590 is  a closed port cylinder and there is a bridge there your not seeing. 

Look at very first pic in thread you can see it. Click on 1st pic to enlarge it and look down cyl sides.

I've heard guys refer to that 590 style jug as "modified closed port", but I don't know if there is a universally accepted term. What do you guys call it?

That configuration, where the transfers are open at the bottom is why a Jonsered 930 is stronger than a 920, or a 372 is stronger than a 272.
Title: Re: Jonsered 590
Post by: Cut4fun on March 13, 2011, 12:10:57 pm
Closed port to me.

 My race 5000 copied after a Marcel Vincent 5000 alky cylinder and even went as far as to remove the bridge to make it open and my woods ported 5000 looked a lot like the 590 cylinder when all the grinding was done by 2 different builders on the cylinder area at the transfers.  Hope that long winded sentence made since.

What is the Mahle number of the 45mm 590 cylinder?

Couldn't tell you since 590 is longer in my possession.  ;)   Been having a fire sale of stuff I no longer want or need.

Started getting rid of 166's, 3120's, 084's and now my 5000's, 590, couple 372's and traded 1 of 3 066 so far.  Might get rid of my woods ported 066 and maybe stock MS660 next.

 Only problem I get rid of 1 and usually get 3-4 more the same week.   ;D

It is right now, getting tire of walking around them  :D  ::).

Found  a NOS jred 590 cylinder in the style that I really like. Only thing I am out of 590 45mm pistons.

This was the reason why I was wanting a look at that 535 45mm piston closer.  ;D
Title: Re: Jonsered 590
Post by: farmboy on October 31, 2012, 08:54:27 am
Good luck on finding a 535 piston.  I picked up a clean kooking 535 thought it just needed a ring.  Not so piston was almost paper thin on the intake skirt.  Husky 51 45mm fits with a little work.  Shortened skirts.  Only problem is the 535 con rod is (if I remember correctly) .010 narrower than the Husky 51 con rod.  I can get you some measurements if you need.

Just sharing some more pics.

Here is a used 590 45mm piston used  compared to the 325 5500 46mm piston new.

Used 590 top and the new 590 top with different views.  I didn't get a lot of used 590 before trading it off.

This one isnt windowed either and I would have no problems putting it in a work saw that was closed port.   ;)  I'm talking stock working work saws here. Not trying to squeeze every ounce of performance from a hot woods port or racesaw.  ::)

The running one, I remover the baffle inside the muffler, it ran good. I have plans to pull it down and clean up the exhaust port and ringland. It's pretty carboned up.
Title: Re: Jonsered 590
Post by: stihlbro on January 08, 2014, 11:53:10 am
I think the av mounts are kinda soft on these saws. I would like to find a dog to install. Removing the baffle made the saw just a bit loud for a working saw. Might add the baffle back and play with some hole sizes to tone it down a bit.

I have a idea to stiffen up the upper right av mount. Haven't tried it yet.

Those are 2 nice looking jonsered 590 you got there.   8)

I have a piece of copper used inside the top right AV mount that makes a ripped one usable.  I still need to get a pic for you.
I pretty sure I traded all my oem cylinder av away, but will look again to make sure.
I think they are around 9.50 new.

Did anyone yet confirm that the 353/2152 piston will work in the 590?

I agree that the non-windowed style ought to work fine in a jug with the transfers open to the case. That's the set up on the 2171/372 and we know there's no problem there.

Bumped this thread for some info.
I have a customers Jonsered 590 I did some work on to get it running again.
Pretty impressive 50cc saw from back in the day, gives my 261cm a run for its money.
I need a brake band for it before I give him his saw back, don't know him and worried about liability with no chain brake. The 503459701 band is no longer available so having a hard time finding one, even a used one.
I found a Poulan 505303836 is a cross reference to it. Is that right? Is the Poulan 325 a rebadged 590? Thanks.

Thanks again, new inventory for this brake band is so far impossible to find. Looking at used I have to buy the whole cover with brake lever and still not guaranteed if band is not broken.
Next time a old saw comes in with a broken brake I'll walk away.

I did the redneck fix on the customer's 590.
Brake band is still a full 360 but with half of its width burn't off .
I drilled a 3/32" hole in the rewind cover and hammered a spring pin in. Now with the brake activated the  band doesn't slip sideways off the clutch drum.
I wrote up a disclaimer on his invoice receipt for him to sign.
Should be good to go.
Here's 2 pics.
