INSPECTION
1. INSPECT VALVE LASH ADJUSTER ASSEMBLY
NOTICE:
• Keep the lash adjuster free from dirt and foreign
objects.

oil.
(b) Insert the SST's tip into the lash adjuster's plunger
and use the tip to press down on the checkball
inside the plunger.
SST 09276-75010
(c) Squeeze the SST and lash adjuster together to
move the plunger up and down 5 to 6 times.
(d) Check the movement of the plunger and bleed the
air.
OK:
Plunger moves up and down.
NOTICE:
When bleeding high-pressure air from the
compression chamber, make sure that the tip of
the SST is actually pressing the checkball as
shown in the illustration. If the checkball is not
pressed, air will not bleed.
(e) After bleeding the air, remove SST. Then try to
quickly and firmly press the plunger with a finger.
OK:
Plunger is very difficult to move.
If the result is not as specified, replace the lash
adjuster.

(2) Using a dial indicator, measure the circle runout
at the center journal.
Maximum circle runout:
0.04 mm (0.0016 in.)
If the circle runout is greater than the
maximum, replace the camshaft.

Check the oil clearance after replacing the
