Finding a Clutch for a Ryobi RY10532 40cc 18” Chainsaw

[billygoat]

The chain is barely spinning on my RY10532 40cc 18” and while I know it’s not a high end saw, I’m trying to fix it because the engine still runs perfectly and starts on the first pull. I’m having a hard time finding a replacement clutch assembly since it’s discontinued though. Does anyone know of a part interchange number or compatible clutch I could use? I believe the original part was HM-308536001.

Redmax uses the same part number

The chinese 37cc clones use the same clutch. Blue Max , Earthquake and the like

Are the Earthquake clutch covers the same as the Blue Max. I need a chain adjuster.

The clutch spring has stretched. I have fixed quite a few clutches with this design by removing the spring and cutting off two or three coils and then refastening. Can't hurt to try.

Try Sears and see if they would have those parts available for the Craftsman Professional 40cc. I loked at mine and don't see a Sears number. The tag says engine family 8HQZS.0404FG

It's a copy of a gz400/4000 oem parts are getting hard to come by for them, and expensive to boot. The ryobi version had nearly everything china made, but the engines were typically still made by zenoah/ redmax. There are many knockoffs thats parts will interchange. Most 35-50 ish zenoah/redmax clones use the same clutch components. Easy to identify by the case design.
