The timing mark (1) and part number (2) on the gear must be facing away from the crankshaft after the gear is installed. Engine damage can result if the gear is installed backwards. Remove the gear from the oven. Caution: Do not use water or oil to reduce the cooling time. The gear can crack. Allow the air to cool the gear.
