Stationary Hydraulic Lash Adjuster Replace
Remove
- Remove the rocker arms from the appropriate cylinder head. Refer to Rocker Arm Replace .
Important:
- Remove the stationary hydraulic lash adjuster (SHLA) from the cylinder head (2).
Inspect
- Inspect the stationary hydraulic lash adjuster (SHLA) in the following areas:
- Replace the SHLA as required.
Install
Important: Ensure each lash adjuster (1) is filled with clean engine oil and the adjuster does not tip over, plunger down, before the installation. The loss of oil in the adjuster lower pressure chamber, or the dry stroking/cycling of the adjuster plunger, will allow air to enter the high pressure chamber of the valve lifter. Air in the high pressure chamber of the adjuster may not be purged causing cavitation and extensive engine component damage.
- Fill the stationary hydraulic lash adjuster (SHLA) with clean engine oil. Take precautions to prevent scratching the pivot sphere area of the SHLA.
- Lubricate the SHLA bores in the cylinder head with clean engine oil.
- Install the SHLA in the cylinder head (2).
- Apply a liberal amount of commercially available camshaft/lifter prelube to the SHLA pivot spheres.
- Install the rocker arms. Refer to Rocker Arm Replace .
