Camshaft Installation - Right Side



1. Ensure that the camshaft sealing rings (1) are in place in the camshaft grooves. Camshaft sealing rings must be in place below the surface of the camshaft journal in order to avoid being pinched between the cylinder head and the camshaft caps.


2. Apply a liberal amount of lubricant to the camshaft journals and the cylinder head camshaft carriers. Refer to Adhesives, Fluids, Lubricants, and Sealers for the recommended lubricant.


3. Place the intake and exhaust camshafts bank 1 in position in the cylinder head bank 1.


4. Position the camshaft lobes in a neutral position with the flats on the back of the camshafts up and parallel (1) with the cylinder head camshaft cover rail.


5. Observe the markings on the camshaft bearing caps. Each camshaft bearing cap is marked in order to identify its location. The markings have the following meanings:


• The raised feature must always be oriented toward the center of the cylinder head

• The I indicates the intake camshaft.

• The E indicates the exhaust camshaft.

• The number indicates the journal position from the front of the engine.

6. Apply a liberal amount of lubricant to the camshaft bearing caps. Refer to Adhesives, Fluids, Lubricants, and Sealers for the recommended lubricant.

7. Install the camshaft bearing caps in the first journal of the cylinder head bank 1.


8. Install the remaining camshaft bearing caps with their orientation mark toward the center of the cylinder head.

9. Hand start all the camshaft bearing cap bolts.

Warning

Use the correct fastener in the correct location. Replacement fasteners must be the correct part number for that application. 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. When using fasteners that are threaded directly into plastic, use extreme care not to strip the mating plastic part(s). Use hand tools only, and do not use any kind of impact or power tools. Fastener should be hand tightened, fully seated, and not stripped.


Refer to Fastener Caution .

Tighten the camshaft bearing cap bolts in sequence as shown to 10 Nm (89 lb in) .


11. Loosen the center intake camshaft bearing cap bolts (1, 2) and the center exhaust camshaft bearing cap bolts (3, 4).

12. Retighten the center camshaft bearing cap bolts (1, 2, 3, 4) to 10 Nm (89 lb in) .
