Clutch issues
Yes, the keyway problem has been taken care of. But be sure not to over grease the clutch grease poits as we have had people putting to much grease into the bearing and you know what happens then.
Also, when checking your clutch torque, your suppose to check it right after start up(engine cold) and check while engine is running. There is a devation between engine static vs engine running as far as your clutch torque reading. Hopefully you have the remote clutch handle that allows you to engage clutch and check torque from the ground. A safety feature and very easy to check clutch torque. Never, never,disengage clutch while engine is hot and leaving it disengaged while engine cools. We've found that air gets between the twin discs and warps the clutch plates, driving your clutch torque sky high. Anything I can help you with let me know, spent alot time on 6000 series pavers.
