Jonsered Chainsaws

[Real1shepherd]

Exactly Kevin.....really a tremendous amount of work to fix ugly....and the chain case was one place that helped determine my opinion of how this saw was originally treated....there is absolutely no evidence of it ever throwing a chain......(though I' sure it probably has) ....there are a couple of light scratches about a half inch long at the top front of the case from a little chain slap from a loose chain but other than that the whole chain case area is perfect. I'll try and get some pics tonight and post them up...LOL..."before pics"....
As far as the price went....I gave all I would have for this non-running saw...free shipping tipped the scale.....he only realized about $50.00 from the deal after shipping and had to bag and box it, get to the PO etc......I didn't have to do anything, didn't have to go look at it....just push the "Pay Now" button and it appeared on my doorstep...LOL!! As a collector I do go after the best looking examples and/or even the bits and pieces I acquire along the way......but not only from the collectors view point but also from the potential resale value of the finished product. Pretty is just plain worth more....even if ugly even runs better.....

Really, really tough to turn down a decent model J'red saw @$75 including shipping! If nothing else, its parts just get filed into bins/containers. I have no problem with saws bringing more with intact paint and OE plastic parts....it's the natural order of things...lol. What gets "ugly" is me with a rattle can.

Looking fwd to the 'before & 'after' pics!

Got to run and tune the 49sp today for a while. I bought this as a running saw a bit ago and it didn't have any teeth on it. The bar was also a beat Windsor that needed replaced.
I finally got some teeth, a nice Tsumani bar I had laying around and I warmed it up to adjust the carb and it's running much better now but not quite done, I didn't get to put it in any wood yet.

So while it was running, I noticed this thick black oil dripping from the back of the clutch cover. The tank looks like someone may have been using old motor oil to lube the chain.
I'll need to dump the oil tank and refresh . . . but it's weird because of where it's dripping from. However I was wondering how I check the oiler adjustment. A search on here revealed;

If it is a 49SP, the oiler is under the muffler on the left.
The adjuster screw is underneath the saw about halfway back on the clutch side.
To set it for normal operation, lightly seat the adjuster screw closed by turning it clockwise, then back it out 1 1/2 to 2 turns.

Since this info didn't come from this thread, thought I'd check with the experts. Is this accurate? Can you add anything else?
Kevin had some good advise a couple pages back about the quantity of oil used, which makes sense.
I'm assuming these types of oilers are all basically adjusted the same, just like the 621 et al.

I hate it when people use old crankcase oil in their saws. I work on the saws of a local family and they have an open barrel that they put any old oil they have in. Motor, transmission, hydraulic, etc goes in that drum along with anything else that falls in and it is nasty. They have spent more on repairs for oiler work than if they just bought bar and chain oil. I have even pulled leaves and baler twine out of the tanks on a few of their saws.

Well, that's just stupid...used motor/transmission/whatever oil not only doesn't have the adhesion factor of a good bar oil, but it's LOADED with contaminants and metal particulates. If you want to destroy the potential of a good oiler, then by all means use that crap....lol

Yep......but it's been done since the chainsaw was invented.....

Sounds like a good place to start to me....

Yeah and when I started they were tellin' me to use motor oil and thin it in the winter with diesel. Then I went to a bulk plant(this is 70's) and they had bar oil...the real stuff...pull it off the bar and it stuck with long strands like snot. So real bar oil has been around since at least the middle 70's. Except for the 'cheap' part of used oil, I see no excuse and runnin' expensive pro saws with used oil was a recipe for early oiler failure....I saw it happen. The metal particulates in the used oil weren't doing the B&C any good either.

1 1/2 turns out yes, is a good starting point. Make the oil run out just before the gas or at the same time...I prefer just before as I indicated earlier. But you gotta STOP using the saw when the oil runs out or you'll dull/overheat your chain.

I think the 45E and 451E share a piston and cylinder. I've never seen an IPL for the 45E, but the casting code is the same. It's a different design than any of the other Jonsereds of the time. The carb cover is part of the rear handle and the a/v mounts go between the cover and the case. The 451E was the updated version and has the more familiar Jonsereds rear handle set-up. As Robin said, the 450 shares the bore and stroke, but that's probably it.

Wow . . . . that's just crazy. Some people just can't visualize or care to think about what it takes for a piece of equipment to operate properly.
But, good news for you . . . . job security!!!

Funny you should mention that

Speak of the devil, they just dropped off another one that won't oil.

Cool! Now he has the ipl.

I sent him my 45e so he can maybe build one good saw from the two.

Do these people use their saws to make a living??!!?? If so, odd that they choose to treat them like this.

My grandfather used old motor oil in the first chainsaw we ever had, a Stihl 041. He stopped that practice after several oiler problems.
IMO There's much better uses for old oil. I knew one guy who hung a tank above the woodstove in his shop he'd then slightly open a valve and slowly drip the oil into the firebox via a copper tube.

Amazing how much oil you can get rid of with just a slow drip.

I have an uncle that used to burn waste oil that way.

I'm enjoying this thread. I bought a new 451E in late 1979 or early 1980. I used it a lot, took care of it and loved it. I sold it to a good friend in 2015 for $100. He later told me that he stole that saw. My brother got a hold of an 49SP that would not run well. I installed a carb kit and replaced the crank seals; runs like a watch now. I also replaced the well used bar and chain with basic Oregon stuff. Here are a couple of photos of the 49SP without the new Oregon bar and chain. This saw fills the void left by the 451E pretty darn well.

 

[beavis331]

Nice 49sp Joe

You just don't see the 45 or 451's

 

[MnSam]

Beautiful, man that looks nice Joe.

Y'all have probably already seen this....there's a seller on eBay, djfshop, who has parted out a Jonsered 930. He's listed quite a few parts, including the P&C with some photos, but didn't include any of the inside of the jug. I don't know if the prices are reasonable, but it's worth a look.
