Running a Toro 30498, 48" w/b. My clutch started screeching today. Hesitant to grab, then screeches while engaged, and doesn't properly disengage. Clutch is a GT1-TR01, 070426 by Ogura. I'll gap the thing, but I don't see how a loose gap would lead to screeching and failure to disengage. Can this thing be disassembled and cleaned up? I'm wondering if oil or hydro fluid might be in it... If it's toast, I can't find this exact model clutch and am searching for a different model # that is a proper replacement. Thanks.
