Lifter / Lash Adjuster: Testing and Inspection

Thoroughly clean all the parts in clean solvent and wipe them with a clean, lint-free cloth.

Use the following procedure for inspecting the Hydraulic Lash Adjusters (HLA):

1. Inspect the HLA friction surfaces for wear and damage. Replace the HLA if damaged.
2. Hold the body and press the plunger by hand. If the plunger moves, replace the HLA.





3. Measure the diameter of each HLA bore. The diameter of the HLA bore should be within 30.000-30.025 mm (1.1811-1.1821 inches).





4. Measure the diameter of each HLA. The diameter of the HLA should be within 29.959-29.975 mm (1.1795-1.1801 inches).
5. Calculate the clearance between the HLA and the related bore. The standard clearance should be within 0.025-0.066 mm (0.00098-0.00260 inch).

The maximum clearance between the HLA and the related bore is 0.180 mm (0.0071 inch).
