Main Bearing Torque Sequence

At this time the manufacturer does not provide main bearing tightening sequence procedures for this component.

Use the correct fastener in the correct location. Replacement fasteners must be the correct part number for that application. Fasteners requiring replacement or fasteners requiring the use of thread sealer are identified. Do not use paints, lubricants or corrosion inhibitors on fasteners or fastener joint surfaces unless specified. These coatings affect fastener torque and joint clamping force and may damage the fastener. Use the correct tightening sequence and specifications when installing fasteners.

Be sure to coat bearings with clean engine oil prior to installation. Be sure that the cap directional arrows points toward the front of the engine block and the cap is in its original position.
