The dreaded stihl 056 SEM ignition.

[Pcorbett81]

Hi everyone, I'm working on an old 056 super and the ignition failed. Well as you may know, there are 2 different types of ignition systems used on these. Bosch and sem. Mine is sem. The Bosch one is the one froggysail posted about fixing on arboristsite. I bought an unreturnable part from my local stealership which I'm guessing replaces the Bosch. I have scoured the internet and all I'm coming up with is incorrect. I believe the sem ignition came on the ts350 as TS360 concrete saws. Do any of you have any of them laying around for sale? Or know someone who might? What about changing the flywheel to the Bosch style? Do you think that is possible? Is that part available anywhere? Thanks in advance

I believe the ignition is still available from Stihl. Part number:1108 400 0800.

It’s is a bit pricey though. I put one in a 045 super A year or two ago. It has to have the sem flywheel. It will not work with the Bosch flywheel

 

[Pcorbett81]

That's the number that I bought for over $200. There's about an inch gap between the flywheel and that ignition module and it has no spark with that one installed

I don't have the Bosch flywheel I have an sem ignition

Pictures are helpful.

I've never seen one .However the IPL mentions the Bosch with it's flywheel but no drawing with it .If I find the time I might look it up in
the service manual up dates if I can find them

I will be happy to get some pictures and part numbers off my saw. Give me a couple days, as I am out of time for the holidays.

 

[Gaston]

Well looks like to coil part number is 1108 400 0804

 

[Gaston]

Hope this helps.

The whole idea seems strange to me .Hiding the solid state module under the flywheel where it doesn't get the fan blast to cool it .Makes you wonder how many of this model plus the iconic 2100 Husqvarna died on the vine because of failed spark .

What part did you get that you can't return?

Hello! New here, and have done lots of thread searching... This one seems to be the closest info... so it's getting bumped. Hoping that is ok!
Working on an 056 Super with SEM ignition and flywheel. The flywheel is the one piece shown above, but has a fin broken off. A few questions:
Is the TS350 flywheel 1108 400 1205 the same, and will it fit? Are the Proline 1108 400 0800 or the 1108 400 0804 the same/will they fit? I can post up some pictures if that will help?
Thanks!

R.

I think @Woodslasher was working on a bunch of these a while back maybe he has one?

No sir, all that stuff has long moved on to new homes.

Thanks for the replies so far! Could someone tell me on the later models of saw (newer) what ignitions were used, and if they were interchangeable? Is it possible that it may have a lobed crank, or did that end with the older saws? Thanks again!
