Keep the lash adjuster free of dirt and foreign objects.
Only use clean engine oil.
Place the lash adjuster into a container filled with engine oil.
Insert the SST's (SST: 09276-75010) tip into the lash adjuster's plunger and use the tip to press down on the check ball inside the plunger.
Squeeze the SST and lash adjuster together to move the plunger up and down 5 to 6 times.
Check the movement of the plunger and bleed the air. OK: Plunger moves up and down.
When bleeding air from the high-pressure chamber, make sure that the tip of the SST is actually pressing the check ball as shown in the illustration. If the check ball is not pressed, air will not bleed.
After bleeding the air, remove the SST. Then, try to press the plunger quickly and firmly with a finger. OK: Plunger is very difficult to move. If the result is not as specified, replace the lash adjuster.
Install the lash adjusters.
Install the lash adjuster to the same place where it was removed from.
