Jonsered Chainsaws

[Real1shepherd]

Also...yrs past some replacement point assemblies, while they worked fine, they didn't fit 100% in the points case properly. If you screwed down the top with them, they would actually bulge the top and not perfectly seal.

You have to look at the OE point set and see where you have to trim to make the top fit perfectly.

I went to the local bearing house today & wouldn't ya know it,they only had one seal in stock,Lol.The guy was putting in an order today & I should have them by the end of next week.I'm having them mailed to me,I can't have someone drive me there for $8.50 (cost of shipping).I also had a chat with the fella there & explained to him that I must have about 30 saws that need seals.I asked him if I called in the seal part # if they'd mail them to me on a regular basis & he said no problem.He said they could even look up the seal by the original part # (Jonsered,McCulloch,Homelite,etc.) The cost for each seal was $4.46.

I just love the mountains of knowledge you and cantdog share freely in this thread. You guys are great.

Hey guys,
Been a long time since I was active, but I want to get my old 90 running again. Parts seem to be much more sparse than they were a decade ago!

I had the saw running way back when, and a friend was running it to buck up a tree when it quit and wouldn't restart. It went under the bench and stayed there. So I'll be going over everything with it and seeing what I can do about a refresh.

My first question is, are rings available? I believe its a 54mm bore, so will any of the currently available 54mm rings work, even if they're not specifically listed for a 90? Nothing looks scored or burned but I figure if I'm tearing it apart, I'll do the rings if I can. Thanks for the help!

You're very kind.....I can't take it with me to the grave so I might as well share, right?

If I ever get my general repair shop going, be interesting to see what chainsaws find me....lol.

Yes, Cabers for one.

Only thing to fret about is the ring end gap of new rings. I've never had any issues, but I always check. 54mm = 2.12598.......2.12598 x .0045 = .0095 If you have more gap than that, I wouldn't worry about it....even .010. You'll just get blow by if the gap is too big. Certainly never smaller than .0095.

I would polish the jug lightly too as a matter of course.

I was just going through the condensers earlier & I'm almost positive I have one.Do the markings on the end have to be the same?

J'reds used similar points equipment on a wide range of saws. The 801/80/90 are completely interchangeable. Robin or Eric could tell you on the smaller saws if the condensers are the same.

If it looks the same, measures the same size and has the same side holding bracket.....you're probably good to go.

I got the 49SP all put back together today & it fired up within 6 pulls.Unfortunately the throttle trigger wouldn't move so I had to pull the filter & the tray that holds it off the saw along with the switch.Apparently someone had been there before me & the switch was already half broke.They had the wire routed over the top of the throttle linkage & it was getting entangled.When I pulled the switch wire off that was it for the switch.Of course I don't need a switch to run the saw.I've got one ordered on Feebay.I ordered one from my local saw shop about a month ago & they told me it'd be in i n about a week.Obviously someone dropped the ball there.Here are some pics of it.

PO's have a bad habit of rerouting things inside the airbox incorrectly.

I'm sure Robin, King of the 49sp's.....would be happy to post a correct pic of a factory-correct routed airbox.

Just went through all my pics of various 49 builds I've posted over the years but found none of the airbox compartment, but I can take one tomorrow soon as I get to the shop. It's pretty straight forward

Looks to be in pretty nice shape Ed!

Got pleasant surprise the other day. Picked up a 590 off ebay......dirty....missing the top cover and air filter cover. Basically bought it for parts for my other 490s and my one 590. Only paid $40 bux for the saw. It arrived safe and sound with the included bar. First thing I noticed was the bar was a D009 that the slot had been ground out to 10MM more or less to fit the older/bigger saws.....in fair condition but certainly not for this saw which needs a K095. "Meh" I says and continue my inspection of this rig. Under the grease and grim I find the saw in very good condition. When inspecting a wrecked saw I look for what might have happened to cause the saw to be retired. Some times you don't have to look far!!! But this saw seemed to very solid......tank was dry and nice and clean inside....compression was very strong too. Pulled the clutch cover off and saw the clutch was snapped in half. From what I can tell that was the tipping point on an otherwise good saw. Eventually someone stole the top cover, air filter cover and air filter. I have all the parts this saw needs in stock I believe, clutch, engine covers, B&C, air filter, crank seals, fuel lines, carb kit etc. I love a good running 590.....amazingly fast, light saws.

Thanks Kevin!

Yeah,when I saw the condition of the saw & a mere asking price of $75 I had to get it.When I found that it needed crank seals I knew I had to learn how to do them sooner or later,so I ordered the seals & popped 'em in.I have another 49SP that I picked up at my local saw shop for $25,that's where the bar & chain came from for this saw.I was going to replace the piston & rings on the other saw,but decided to use it for a parts saw.

 

[Real1shepherd]

Picking up rehab-able saws for less than $100.....always good stories and good endings!

Always wanted a 70e. Smallest J'reds I have is the 621. I have a source for a nice 70e @$200 plus shipping. But it's got the SEM's module under the flywheel....not busting down the door to get it.

I've been lookin' at that Echo 7310.....new, but made like a pro old school saw. Conventional carb, no autotune and 73.5 cc.

Robin, good snag!

Hope it wasn't a deal where the saw chain got stalled in wood and they ran it until the clutch snapped. I'd worry about the crank bearings being spun in the case. Hopefully, it's just the clutch!

Here are a few pics of the $40.00 "Dirty Bird" Just as it came to me. Has spark and good compression. This is a 1988 version, built in the 18th week, the 298 th unit.....89 was the last year of 490 and 590 production. 590 is basically a souped up 490 and only made from 86 to 89. A number of upgrades including the 45 MM P&C which is for all purposes, identical to the much sought after Husky 55 EPA P&C which was a pretty limited production saw. The 590 is a lot of power packed into a light weight, Partner designed 51 CC saw frame.........and much better handler than the Husky. Lot of grime but not from use but from sitting somewhere in a dirty environment........quite red under it all!!!

Doesn't look over heated.........I suspect someone tried to reinstall it with a hammer and punch rather than a wrench......noticed it's got a brand new rim drive on it.
A pic of the donor saw clutch. Off a Partner 500....a bit dirty from sitting here but other wise in good condition.

 

[Clyde85]

Hey cantdog I believe there is a 4 or 590 jreds and a partner 500 for sale on Kijiji Ontario. If interested.

 

[Real1shepherd]

We've talked about this before in here.....always baffled about people sending/selling dirty saws.

And it's not just saws....I collect vacuum cleaners and most of them are sent to me with dirt still in the bag....or worse.
