Exhaust Camshaft Installation
WARNING: This page is about a different variant/trim than selected.
- Install the camshaft bearing lower front cap (1).
- Lubricate and install the hydraulic valve lash adjusters (1) into their bores in the cylinder head. Refer to Adhesives, Fluids, Lubricants and Sealers .
NOTE: Pre-fill the low pressure chamber with engine oil. Maintain a vertical orientation of the assembly to retain the oil in the reservoir and high pressure chamber. Do not install the lash adjusters without pre-filling the low pressure chamber. Apply engine oil to the outer diameter surface of all adjusters.
- Lubricate the valve tips. Refer to Adhesives, Fluids, Lubricants and Sealers .
- Lubricate the roller bearings with valve rocker arm lubricant. Refer to Adhesives, Fluids, Lubricants and Sealers .
NOTE: Used rocker arms must be returned to the original position on the camshaft. If the camshaft is being replaced, the rocker arms actuated by the camshaft must also be replaced.NOTE: Pre-oil roller bearings before installation.
- Position the valve rocker arm (1) on the tip of the valve stem and on the lash adjuster and lubricate. Refer to Adhesives, Fluids, Lubricants and Sealers .
- Lubricate the exhaust camshaft lobes and journals with camshaft lubricant. Refer to Adhesives, Fluids, Lubricants and Sealers .
NOTE: Apply lubricant to all lobes and journals prior to installing the camshafts.
- Set the exhaust camshaft (1) on top of the rocker arms in the camshaft bearing journals with the actuator timing mark at approximately the 1 O'clock position.
- Install the camshaft cap bolts (3) into the camshaft caps (2).NOTE:
- Do not apply final torque at this time. Camshaft cap final torque is applied in sequence when all caps are installed on both intake and exhaust camshafts.
- To properly position the camshaft caps, install the camshaft cap bolts into the camshaft caps prior to installing the camshaft caps on the camshafts.
- Install the camshaft caps (2) and hand start the camshaft cap bolts (3).
