Facing the same problem. I know this was a while back but how did you get on Bob?

I did a couple of them Bill, you will need to make a few bits.

 

Barrels are basically the same but the exhaust ports are a different shape and size.

 

 

The exhaust is Stihl no 11241400604, comes in two bits

 

 

 

You will need to get a couple of long m5 bolts in the two lower muffler holes which need to go on before you bolt the back part of the muffler onto the barrel, then make up two spacer tubes with two small tabs to pick up on the forward original exhaust muffler supports. Thats about it.

What brand of cylinder did you end up using Bob? Have they been ok?

Thanks for the thorough reply!

Did you consider drilling the cast type clip on muffler to fit bolts through? The cost of the non OEM cylinder and exhaust puts it only about 40/50 quid cheaper than getting a stihl cylinder- so but less tempting.

Have the non OEM cylinders been ok?

Yes they have been ok, once converted the barrel swap is easy.  I think the barrel killer is when they have a big bar fitted and are being used flat out to cut huge stumps really low to the ground, the vent side of the cooling is facing downwards and the heat cant get away because its so close to the ground.They never have a problem other than when cutting stumps so I have put it down to this.
