HUSQVARNA HUSQVARNA THREAD

[Simondo]

I saw the parts number on partstree, but it's not always the last Husky part number, when parts become NLA in US they dont update, good example is 254 crank who is avaible in Norway with new part number.

If my memory is correct you can use closed port piston in open port cylinder, ie, 444 piston in 44 cylinder.
Wasnt there one 268 closed port version?

The XP was i believe ...some say it doesn't exist !

Be aware that at least some such sellers are listing the parts as available until they try to get it and find it NLA. They aren't really updated on what's NLA from their source. The good thing is of course that they may have stuff that is NLA from the brand in stock - but so may the brands own dealers...

Thanks for the link anyway!

Yes, while I have had this happen once, where something I ordered became NLA from a vendor they did later update it as such. Also purchased same part from a different vendor who still had old stock. Was surprised at how much old stuff the vendor I gave the link to before actually had in stock, even stuff for other brands from the 1970's. Overall, I must say that I've had good success when ordering genuine parts for older Husqvarna power saws. The piston in question here was listed as available from multiple vendors for what it is worth. Guess ya just have to order one to find out. One thing for sure, is absolutely 100% certain, none of this can be done with the ever elusive Stihl brand.

A bit about 133/234/238 vs 242/42/246
Many think they are build on the same plattform, but that is not how it is, both classes are unique.
While we can use lots of parts both ways there is a few main differences.

Crank is different, 133/234/238 crank is a tad smaller, but there is more, 133 con rod is 53,5mm long (center to center) while 242 con rod is 56,0mm long, that brings us over to c&p, you can't swap them over to the other plattform.

Crankcase difference, 133 on bottom, 242 on top, actually it's an 42 case.

A few other pictures for those who want to study the crankarea details.

thank you
Does everything else fit?

Yes, the 268xp and Spesial (same saw really) was closed port (with larger transfers than the 266) - and they used the same piston in the late production open port version (according to the IPLs).

The XP was i believe ...some say it doesn't exist !

The 268xp was made from 1987 to 1991. There even have been rumors of a 268SE, likely because the first XP ones said SE on the number tags and XP only on the covers (decales really - this was fairly common on early Husky XP saws). As I mentioned the same saw was made a little longer than to the point when it was replaced by the 272xp in 1991, but then was renamed 268 Special (at least some of them said XP on the number tags, possibly all). At the same time the open port 268 was introduced (it really replaced the 66, that had the same top end) as a less costly alternative to the new 272xp (that replaced the 268xp as the pro model).

Confused yet? To confuse further, both the 266xp and the 66 still remained in production for long after this, from some time (yet unknown to me, but likely around 1991-1993) at the TOMOS factory in Slovenia + there is the Brazilian production of the 268 and 272xp.....

you can swap most of the other parts around, crankcase, crank, top cover, muffler, p&c is unique on 133/234/238.

238 came with adjustable oil pump in 86.
234 second version came with same clutch as we find on those old 242's.
133 tank is very special, gone try to see if it's possible to swap over throttle&lock from 42, and if it fit propleby.

Ignition parts, flywheel, clutch parts, side covers, oil pumps, xpg parts can be swapped around.

Not confused at all Niko, your explanation is excellent .. the time line of all these changes isnt something i knew much about as iv not had many of that group ( if you have them you tend to look for more info ) of saws. The thing I knew about was the fact that the 268 came in open and closed...but that some will tell you they were only open.

I belive they make parts in Brazil, it's not long time ago since I bought one new 254 piston, made by Mahle, cartoon made by Brazil.
If those 268 pistons is made for closed port cylinders, and they have same port shape as 266 had, I belive it's why those part # is the same nowadays.

We all know that most pistons nowadays have one part #, AB pistons only, but in their time from KS and Mahle they had A B pistons, so I think they are willing to have a socalled allround system

I didn't know that Mahle has a factory in Brazil, but I know that KolbenSchmidt has, and make top ends at least for Brazilian made Husky models.

As I recall it, the cylinder/piston size lettering once went all the way up to E, but mostly has been about A, B and AB for some time now. I believe its roots are back when the cylinders weren't plated, and cylinder bore wear was more of a concern?

Maybe it is time to look up some Brazilian IPLs? I don't think they still make the 268 though, but they did until some years ago.

Edit; The Brazilian website doesn't list IPLs.

I wouldnt be surprise if Mahle also has a factory there, it's a bit odd they use cartoon labeled made in Brazil.

A bit more of 133 vs 242.
One thing we cant use without doing some heavy modds is the fuel tank to 133, but we can go the other way and use 42/242/246 fuel tank on any of the 133/234/238, trottle lock is the only thing to fix (or just do a carb swap)



This is one 242 fuel tank.


133 use 5xAV, instead of the 242's 4xAV
Thats why one of the lower ear for rubber AV is a bit different 133 vs 242

133 crankcase lower AV mount, mounted same way as the other 4 AV


242 lower AV mount, kinda same style as we use on 346 etc

@exSW , Just thought I'd let you know, I see HL Supply has Caber 266 rings on deal of the day, $9.99.

Found a 2016-07 268 IPL on the Mexican Husky website, and the piston assembly is 544 22 39-03, not the same as any of those listed for the Swedish made saws.

My somewhat educated guess is that this is a KS piston made in Brazil.

There also are 2016 272, 281 and 288 IPLs at that site, and likely more...

Enjoy it. Update us after you run it a bit.

 

[exSW]

Over here the last day or two I've ordered most of the parts for the 266. Piston kit,bearings,av's,Husky av wrenches,newer clutch cover. Still need seals,o rings,fuel line(does it take the curly),maybe an oil line. Carb kit's already here. Talked to the powder coat guy. Much as I have in it I'm going to own this saw forever.

 

[Stump Shot]

That saw will last you forever. Like to see your CC halves after powder coating. After seeing some white death recently, this would seem a prudent measure to me.

Done with the 545 G rebuild, saw and parts have cost me 100$.
Stole carb + coil from one 550 part saw, and a few missing G parts...
Left to do MM and cut some wood
