Who made this cylinder?

[PB]

This cylinder came off my Jonsered 625 but have never seen this casting before. I know Mahle, Gilardoni, and Husqvarna cylinders but have never run across this before. I don't believe it is aftermarket; there is a thread here discussing this cylinder marking on 2 other 625's. The marking is also on the inside of the piston.

Does anyone know the manufacturer?

I know this doesnt help much, but it is certainly factory. I bought a 61 husky off the original owner, cylinder has the same stamping. 85 model.

 

[husq2100]

see the stamp on the base that is a "K" over the top of an "S", that is the manufacture. Im not sure of their name, but they did alot of OEM stuff for husky's. I personally have an old 288 and some 2100 OEM stuff that is made by them.

I have seen that mark before on Husqvarna cylinders but I have never tried to find out who made them. I believe I remember a thread from quite some time ago that explained this marking, but again I did not care enough to actually read it.

I believe those were Kolbenschmidt brand (but not completely sure.)

I know they did make two-stroke top ends for a few years for quite a few applications.
The one dealership I worked at had two new Stihl 026 piston kits NIB on the shelf that
were Kolbenschmidt and they had the same "KS" marking on the inside of the pistons.

Thanks!! It has been perplexing me for the past few days.

Was wondering the same; found that marking not long ago in a piston in a 272. "Kolbenschmidt", eh? First time I've heard of 'em.

They're a high-quality brand. They make cylinder sleeves for Mercedes Diesels among others.

The word "Kolbenschmidt" means piston-smith in English.

Kolbenschmidt have done a lot for Stihl in the past 024,026,075/076 P+C to name a few. In recent years they have made a reappearance with often the smaller saws with Mahle cylinders containing KS pistons. I think they are now again doing several P+C kits for Stihl, some MS660s have them;

Some other examples in a thread I started. I believe a lot of people are mistakingly calling KS pistons and cylinders Stihl branded ones;

Sure - it is Kolbenschmidt from Germany

It started as KarlSchmdt but changed name when the business changed hands.

Everyone that is a K & S from early production seen them on a lot of Stihl chainsaws like mahale both are factory cylinders and sale for a pretty penny on ebay if in real good shape comes from Germany.
