(b) Insert SST's tip into the valve lash adjuster
assembly's plunger and use the tip to press down
on the check ball inside the plunger.
SST 09276-75010
(c) Squeeze SST and valve lash adjuster assembly
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 air from the high-pressure
chamber, make sure that the tip of SST is
actually pressing the check ball as shown in the
illustration. If the check ball 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.
3. INSPECT CAMSHAFT
(a) Inspect the camshaft for runout.
(1) Place the camshaft on V-blocks.
(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.
HINT:
Check the oil clearance after replacing the
camshaft.
(b) Using a micrometer, measure the cam lobe height.
