Hi Guys,
Yesterday I took the 260 for a long, long drive ending with the fan clutch ceasing.
I’ve dismantled the fan clutch, cleaned out the gunk with carb cleaner, got it turning freely although with a slight drag and filled with 20/50 oil (will get some silicone oil and do again if worth keeping this clutch) and reassembled.
I’m not sure of the best way to test if it’s working properly. I’ve done the newspaper test at idle and the fan slows down marginally, but doesn’t stop spinning. When spinning the blade by hand with the engine stopped and cold it spins one blade short of a full revolution.My understanding is that at XXXX? rpm the clutch should disengage and this can be heard by a change in sound, i.e. the blade slightly slowing. Can someone point me in the right direction please? I’m not sure on how many times it should spin freely with the engine stopped and the RPM at which the clutch disengages.
Many thanks
Tim
