Bunch of big stihl clutch drums, OEM or Aftermarket?

[Nate.]

So I acquired a bunch of stihl drums from a closing dealership. All these sprockets where mixed in with a bunch of marked OEM sprockets. I'm wondering did stihl make sprockets that didn't have part numbers on them? Or could they be old Oregon sprockets? Everything else I got is OEM down too the smallest pieces. The second picture is for size comparison, The middle drum is for a 066.

I dont know much about stihl but old jonsered"s" part almost never had numbers on them. If the part was big enough it got a letter. Certain letters went to certain models. U have to have the secret decoder ring to figure it out!

The circled drum reminds me of a 2 series husky drum.

Thanks for the reply. I haven't noticed any numbers on these they just say Stihl and the pitch. I would just assume they where aftermarket if it wasn't that everything else from the dealer is OEM. I believe the drum you circled is a 045/056 drum. I've attached a image of that drum next too a 1115-160-2905 drum. As best I can tell They are identical.

Those with the washer look like a 056 clutch drum maybe. 1115 is 045/056 series I believe too if I’m not mistaken.

Yes your correct the 1115 is 045/056 series. I agree i think it's an 045 or 056 drum. What I'm not sure of is if the ones without part numbers are aftermarket or OEM.

Anyone interested in buying all 12 of these drums? I can probably find out what most of them go too by matching them too drums with part numbers.

Thanks.

No stamp = not Stihl

I might be interested Nate.
PM me but you have to run them down. I don't have time. Can show you how to do it.
They could also all be knockoffs.

99% of the time Stihl uses there logo in some way.
They should all have Stihl stamped in part numbers to be OEM

Looks very close for markings somewhere

I’ve looked them over and they don’t have the S stamped in or a part number. So I’m going too assume that they are aftermarket.

Thanks, Nathan.
