Re: Heavy Duty Fan Clutch vs Standard Fan Clutch
You have to make sure the fan speed is rated for the clutch and max engine speed.
Standard duty clutch spins fan about 60% of engine speed.
Heavy duty clutch spins fan about 80% or more of engine speed.
Standard duty fan is usually rated for about 4000 RPM or so which would be good to about 6500 engine RPM but could come apart at high speed with a heavy duty clutch.
