1. Install the upper inserts to the cylinder block (1).

Important: The upper insert has an engine oil groove. Install with the engine oil groove to the cylinder.

Notice: 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 locking compound or sealant are identified in the service procedure. 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 in order to avoid damage to parts and systems.

Important: Gradual and uniform tightening is important for main bearing bolts. After tightening the main bearing cap bolts, inspect in order to check that the crankshaft rolls smoothly when turned by hand.

2. Install the five main bearing caps (2) with the lower inserts and secure with the ten main bearing cap bolts in order 1, 2, 3, 4 and 5.

Each main bearing cap is embossed with an arrow mark and a number. When installing each bearing cap to the cylinder block, point the arrow mark toward the crankshaft timing pulley side.

Tighten the main bearing cap bolts to 54 N·m (40 lb ft).
