3.22  Stationary Hydraulic Lash Adjuster 

Remove 

1 

Remove the rocker arms from the appropriate 
cylinder head, refer to 

3.20  Rocker Arm

. 

2 

Remove the stationary hydraulic lash adjuster (SHLA) 
from the cylinder head (2). 

 

 

CAUTION

 

•  Do not stroke/cycle the stationary 

hydraulic lash adjuster (1) plunger 
without oil in the lower pressure 
chamber. 

•  Do not allow the stationary hydraulic lash 

adjuster to tip over, plunger down, after 
the oil fill. 

 

 

 

Figure 6A1 – 362 

Clean and Inspect 

1 

Inspect the stationary hydraulic lash adjuster (SHLA) 
in the following areas: 
• 

a plugged oil passage (1), 

• 

a scored or worn camshaft follower pivot 
area (2), 

• 

a damaged or broken retainer (3), and 

• 

a severely scuffed or worn SHLA body (4). 

2 

Replace the SHLA as required.

Reinstall 

1 

Fill the stationary hydraulic lash adjuster (SHLA) with 
clean engine oil. Take precautions to prevent 
scratching the pivot sphere area of the SHLA. 

2 

Lubricate the SHLA bores in the cylinder head with 
clean engine oil. 

3 

Install the SHLA in the cylinder head (2). 

4 

Apply a liberal amount of commercially available 
camshaft/lifter prelube to the SHLA pivot spheres. 

5 

Install the rocker arms, refer to 

3.20  Rocker Arm

. 

 

 

CAUTION

 

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.
