Water pump - Just put it against the shaft with a bit of grease and slide the impleller over it.<br /><br />Ignition key - Push it back into the switch and turn it.<br /><br />Flywheel key - Put it back in the slot on the top of the crankshaft.<br /><br />I think you get the message. We need a bit more than 'drive key'. Let's start with engine horsepower and serial number. Then a bit more info about what you were doing when the 'drive key' fell out.<br /><br />Chris..................
