FEATURES: Quality steel bearing cage NOT A CHEAP plastic bearing cage that is becoming more common in the marketplace. Quantity required: 2 INSTRUCTIONS: Drain oil from compressor pump. Remove the belt cage. Remove the compressor belt, pulley and key. Avoid using a hammer to remove pulley. A pulley puller will help to insure you don't need to buy a replacement pulley. Most are made of cast iron. Remove the 4 retaing screws from the bearing cap. Remove head bolts, and separate cylinder head. Remove old bearings from crankshaft. Check that significant other isn't watching and saturate a cotton rag with water. Wrap new bearing in the wet cloth. Make sure entire bearing is 100% covered with wet cloth. Place cloth in microwave for 2 minutes. Cloth will be boiling temperature, carefully remove from microwave and install bearing on compressor shaft.
