Best chain and bar setup for Jonsered 70e.

[Sammydub50]

Hey guys, my Jonsered 70e has a 28" chain and windsor speed tip bar. Chain is on its last leg. I saw a 20" carlton bar and chain combo on Ebay for $29.99. Is this a good setup? What would you guys recommend as the optimal setup for this saw as far as power, speed and torque that this saw has? I read some recommend 18" while others like 28". I'm trying to decide if I should get a replacement chain or get a whole new combo. The price is about the same for the combo or just the 28" chain. My 28" makes my saw tilt to the dirt while idling which is kind of a pain. Anyway, any help is appreciated.

thanks
Sam

The Carlton bars are good enough bars...made in Germany...I have 3 or 4 and the wear well..perhaps a tad heavy but all mine are 20". That said ...the problem you have is they don't come in the old style Jonsereds large mount to fit your 70E. Winsor always was a good choice but I don't think they still make that mount either. The best bet, and best bar for your saw is still available from Tilton's through any Jonsered dealer. These bars are of the finest quality...made in Japan by Tsmura. They are kinda spendy but wicked nice!!! I bought two 20" on Ebay with ful chisel Oregon chain combos for $55.00 each a couple yrs ago...

So this one won't fit my 70E?

Your bar looks awesome! I found one identical on ebay but its a 24" and 79.99 plus shipping. I may try one. So 70 and 70e bars are different?
Finally, my muffler looks like the ones your 49's have and not like your 70e muffler (I read your rebuild thread...its a masterpiece). Is your 70e muffler modified? Thanks cantdog!

Hard to say what it really will fit, as the bar mount pattern is unknown to me. The saw brands mentioned doen't help much.....

Edit; Looked a bit harder, and found out it likely is a "small Husky" mount bar, that surely won't fit on the 70E.

I think 28" is too much for a 70E. The longest I run is 24" but prefer 20". I was fortunate and got some when Baileys had a closeout on them and if you keep your eyes open they periodically will come up on ebay or elsewhere. And for what it's worth , run a 7 tooth sprocket. I recently am using a Stihl bar on one of my "big stud" jonsereds. I ground out the adjuster hole, wrapped a piece of tig weld wire around the studs , about 3 times on each stud , and it worked. When you wrap the wire it should look like a long "s" with circles on the end . I use a vicegrip to keep it snug on the studs when wrapping. Can't remember what size wire I used but subtract the stud diameter from the bar mount groove and divide by 2

No that bar won't fit the older Jonsereds bar mount...besides that's not that great a bar....laminated bars are not very good as a rule. The 62/621, 66E, 70/70E, 80 and 90 and other large pro series Jonsereds of the same era take the same mount...and as I said those are getting very hard to come by unless you go through a Jonsered dealer and buy a Total. The Carlton I thought you were speaking of was this style but it won't fit the olsder Jonsereds either...Sorry these are the only pics I have of any of my Carlton bars and don't show the entire bar...but these don't fit the 70E either..

That muffler is the late, early spark arresting muffler and is stock except the interior baffle holes have been enlarged a tad..and thank you for the kind words on the 49sp& 70E build...it was fun...

I'm gonna throw in a couple other pics of the bars that will fit this mount also....

Your 70 has 10mm bar studs not 8mm like the later jonsered huskys.The mount is the same the bar stud is the difference. The 10mm bars are getting harder to find. 20" or 24" bar will be fine.

 

[VTWoodchuck]

That 70e is a TANK! My Dad still has his from early 80s and uses it regularly. We used to sell firewood and it was the only saw he had. Bet that sucker has cut thousands of cords of wood. He laughs at me for having a 'limbing' saw.
Good luck with your bar search.

The "large Husky" mount is 9mm, and will fit if the stud slot is widened slightly - the "small Husky" is 8.2mm in the slot, but the oiler holes won't fit even if you widen it.

Hey guys, thanks for all of the help. I think I'm gonna splurge and get a 20" or 24" Total (super bar). Man, those things are price-$79.99+shipping on ebay with chain. But, everyone says its worth it. I suppose I'll have to wait for Bday or Christmas tho ;-)

 

[fearofpavement]

So what do you cut? ie, what size bar would suit your needs? Make you bar buying decisions based on your needs, not necessarily what the saw can handle. I think that if your longer bar is in decent shape, it would warrant a new chain. and then maybe get a 20" for it as well. Then you can pretty much cut anything you need to.

Get several chains, and make sure they are good ones! Also check that the drive sprocket is in good shape, before you run the new attachment on the saw. :msp_wink:

Honestly, the only thing I have to cut is my own trees on about an acre-probably 9 at the most. I'm not sure if I really even plan on felling them or milling. (I know-I know) most of you guys probably do your cutting for a living or live on incredible spreads. I'm just a lover of all things mechanical and I love to tinker and have things with the most power within my budget. I started out with a crappy homelite 240 (always runs good though). Next, I bought a stihl 039 with a muffler mod and a badly cracked crankcase that had been run in the dirt that I stumbled across on craigs for $45. I found this after I had already bought my Jonsered 70e on ebay. After I rebuild my impressive Stihl, I ran into Cantdog on here who helped my figure out why my 70e was bogging down (wrong intake gasket in carb rebuild kit). Now, I have one crappy little limber saw and two beasts of saws and I'm hooked. I planned on selling one of the saws but I like them all for their different characteristics, sound, history, etc. All I have left to do is buy a good bar and chain or just a chain for my jonsered 70e. I think for what I have to do, which isn't more than a few weekends of cutting wood a year, I'll just keep the 28' windsor speed tip and get a new chain for it. Any of you know if this chain will work? It seems that it will. Same drive lengths et al. Thanks as always.

18"

My 70e came with an 18" Stihl (sorry) Rollomatic E bar, I've put a new carlton A3LM-BL-66E chain on it. It runs great!

I hope you use adapters on the studs, as the slot in the Stihl bar is much too wide for the studs.

I don't think so. I just looked at some Sugi Hara bars (24") for the 70e, and there they also mentionnned something about blue plastic stud spacers........

What sort of adapters should I use for the Stihl bar?

The easiest is to make two metal "rings", that fit snugly on the bar bolts and fill out the slot in the bar as exactly as possible - or you can adapt the large Husky mount made to fit a Stihl bar on Husky saws (Baileys sell them) by opening them where they fit over the studs.

Using the Stihl bar without suitable adapter will create several issues.
