Title: Cylinder help again
Post by: Miller-Thinner2 on December 29, 2013, 11:09:49 am
I have a 266xp and I have to replace the cylinder and a friend of mine gave me 2 cylinders and he "thinks"  1 was off a 266xp and the other off a 630 jred and possibly off an other model saw.

Can someone tell me what the cylinders are off of if i post pics and number? Or if they will work for me.

cylinder #1
50Z13  W6
V MAHLE

Cylinder #2

Your secret may be in matching the looks of the intake side of the cylinder?
Title: Re: Cylinder help again
Post by: HolmenTree on December 29, 2013, 11:26:32 am
Cylinder 1 with the rubber on the intake looks like a 630 cylinder with the closed port solid flange base.

In the past, SawTroll has been able to identify Mahle cylinders by the casting numbers. Perhaps he will be along to let us all know. I will snoop around and see if I can identify it.
Title: Re: Cylinder help again
Post by: HolmenTree on December 29, 2013, 12:36:08 pm
Both cylinders are closed port from seeing the solid flange base. #2 cylinder has the newer style high muffler which might make it a 268

Near as I can tell the '50ZN13 W6' is a 266 jug. I cannot find anything on the 'fk' jug at all!

Looks like both have bolted intake to me.
Rubber on the first looks like the seal.

First one Is Mahle think could be for 266, 50ZN13
Second is a Kolbenschmidt cylinder FK 948.

Should be different diameter on them 50mm on 266, 48mm on 630.

Remove the boot on the Mahle, they could be the same...

Title: Re: Cylinder help again
Post by: Miller-Thinner2 on December 29, 2013, 01:51:30 pm
should I post some more pics? 1 without the boot or inside of cylinder.
The guy I got it from just told me he is pretty sure 1 is off a 266. could I pull my cylinder off and just try it to see if it works. My cylinder has different casting numbers then both of these
Title: Re: Cylinder help again
Post by: KilliansRedLeo on December 29, 2013, 02:23:08 pm
I assume from the pictures that all you got was the cylinder, correct? Take your calipers and measure the diameter of the bore on #1 if it is a 266 it will be 50mm as Magnus stated.

Quote
Should be different diameter on them 50mm on 266, 48mm on 630.

What are the casting numbers of the cylinder on the saw now?

What makes you think your cylinder needs to be replaced?

If you have both the cylinder and piston, and it is 50mm your home free, otherwise you will have to pull your jug to be sure
Title: Re: Cylinder help again
Post by: Magnus on December 29, 2013, 03:16:23 pm
Number 1 is 50mm as Mahle has it numbered as 50ZN13

I just have the cylinders, My cylinder possibly can be fixed. But if 1 of them cylinders will work on my saw it would be easier just to swap cylinders.

Well that would be cool but again why do you think your cylinder needs to be replaced? Pistons usually suffer the most damage, so if the piston is damaged then it will cause damage to the cylinder which can sometimes be cleaned up. All of this is moot if the damage is external to the bore, like broken exhaust flange or cylinder fins.

Post by: Miller-Thinner2 on December 29, 2013, 04:36:22 pm
The previous owner stripped the muffler stud out and drilled it out very big and filled it with jb weld and drilled the muffler so they could put bigger studs in. It all come loose when I got it. so i cleaned the holes up and put more jb weld back in it then drilled it and tapped new threads but its all loose again,
I'd aluminum weld over it and drill and tap new threads if I had the equipment.
 
Id take suggestions on how to fix it. I just want it fixed right not the half ass job thats it has now lol
I think my easiest quickest fix would be to swap cylinders if I knew that 1 of them was a 266
Title: Re: Cylinder help again
Post by: KilliansRedLeo on December 29, 2013, 05:49:15 pm
Welding up the holes and retooling is the best way to fix the problem with the current cylinder.

Your theory of replacing is the cheapest way to go since you have no $ in a replacement. I think you can be fairly certain that #1 is a 266. Give it a shot, you have nothing to lose since you would have to remove the current jug to have it repaired anyway.

I have a 61 piston and ring and just to see I put it in cylinder #2 and it fit. It was to small for cylinder #1. So now im going to just go ahead and try it, if it works then great.
If it doesnt I'm gonna have to find some to weld it the holes so I can get it re threaded.
Title: Re: Cylinder help again
Post by: KilliansRedLeo on December 29, 2013, 09:14:12 pm
The 266 had a 50mm bore, the Jonsered 630 is 48mm as is the Husqvarna 61. IIRC the Husqvarna 61 and the Jonsered 630 are basically the same saw.

Good luck with the cylinder replacement. IIRC the torque specs state 8-9NM for the jug, and use a NEW base gasket! As well as a good amount of 2-stroke oil in the bore, you do not want to start the saw with the cylinder dry!
Title: Re: Cylinder help again
Post by: HolmenTree on December 29, 2013, 10:52:56 pm
Miller thinner what is the bore size of cylinder #2?
From looking at the newer style high top muffler I'm curious what model it might be from.

Yes, but the 630 used the closed port top end of the 162SE, not the open port one of the 61.

Yes, and people often overlook it, as it is quite discrete. KS actually made a lot of top ends for Husky and Stihl back then (1980s and early 1990s), but I don't know what happened to them later?
Title: Re: Cylinder help again
Post by: Magnus on December 30, 2013, 03:11:12 am
They are still doing good cylinders. http://www.kspg.com/en/divisions/hardparts/ks-kolbenschmidt/

Gilardoni, Mahle was more Popular on Jonsered/Husqvarna. Kolbenshmidt made cylinders for Stihl and after market ones for those built here, but I don't think I have seen it on Husqvarna saws from here from factory.
Jonsered and Partner had KS cylinders from time to time.

All the non-decomp 262xp cylinders I have seen or heard of have been KS, and a lot of 254xp cylinders from the early 1990s as well.  ;)

Their "logo" is real easy to not notise, as it is quite discrete....

At least halv a dozen (pictures on forums) + several statements, and my brothers early 262xp has a KS as well. Actually, I have never seen or heard of a non-decomp 262xp that didn't have a KS cylinder. Many consider those cylinders better than the later decomp Mahle ones, as they have a smaller combustion chamber.
What I doubt at this point, is the existense of 262 Gilardoni cylinders, as I have never seen a picture of one, or heard of one - but maybe you have one in your vast Collection?
Title: Re: Cylinder help again
Post by: Eccentric on December 30, 2013, 02:15:20 pm
Different Husqvarna saw series (although one from a similar time period)..................but all the earlier non-decomp 288XP cylinders that I've seen (those without a boss cast into them for the comp release valve) have been KS cylinders.  The KS cylinder that I used to build a 288XP last year was very high quality, and made for a very strong running 288XP.

The comp release 288XP cylinders (and those with bosses that haven't been machined) that I've seen have been Mahle.

This will be interesting. The last 5 i had here all were Mahle and with decomp.
I have two or three here in collection, I think they all have decomp too. I will check what they have.
I have more cylinders in the boxes I will try to find...

I know there was Gilardoni cylinders for 262, aftermarket ones. Not sure who sold them though, Likly not HVA...
I put on a couple of them and you could tell they were different from color and it caught my attension.

Magnus, my 262 KS cylinder is a darker grey than the other 262s I have. They all have Mahle. I have never seen a Gilardoni cylinder for a 262, although that does not mean there aren't any!

I put the cylinder #1 on this evening and it works great. The now has a muffler that is on tight.  Also I looked at that link that was posted in this thread and I could not find the #'s for the cylinder I removed.     Gilardoni  5034479

It is a great tool to have when you stumble on a box of cylinders you don't know what they are for.

closed. But I can not confirm it is a 266. It had a 266 starter side but no serial number# tag when I got the saw.  I dont have much knowledge on saws but the cylinder I put on it was off a 266 if that matters. From my understanding some cylinders are interchangeable so it prob doesnt mean anything

Dont know if you have room in the old muffler stud area but could you tap in an oversize thread rethread some aluminium rod screw it in with locktite the redrill and tap for standard muffler studs, long winded method but maybe cheaper than aluminium welding
Title: Re: Cylinder help again

Unless you have a lathe in your garage I would say the welding is MUCH cheaper.
