5. With the specified air pressure appli€d, push up the
timing plate; the synchronizing piston will pop out
and engage the intake secondary rocker arm.
Visually check the engagement of the synchronizing
prston.
NOTE;
The synchronizing piston can be seen in the gap
between the secondary and primary rocker arms,
With the timing plate engaged in the groove on
the timing piston, the piston is locked in the

original position.
Visually check the disengagement of the synchro-
nizing pistons.
NOTE:
. When the timing plate is pushed up, it releases
the timing piston, letting the return spring move
the synchronizing piston to its original position.
7. Replace the intake rocker arms as an assembly if
either does not work correctly,

Replacement (Cylinder head removal not requiredl
NOTE: Cylinder head removal is not required in thisprocedure.
The procedure shown below applies when using the in-
car valve spring compressor (Snap-on YA884S withY48845 - 2 A7/8" attachment).
!@@ Alway wear approved eye protection whenusing ihe in-cai valve spring compressor.
1. Turn the crankshaft so that the No. I and the No. 4pistons are at top dead center (TDC).
2. Remove the cylinder head cover and the rocker arm
assembly.
NOTE:
. Refer to page 6-30 for rocker arm assembly
removat.
. When removing or installing the rocker armassembly, do not remove the camshaft holder
bolts. The bolts will keep the holders, springs
and rocker arms on the shaft.
. Refer to page 6-46 when installing the cylinder
head cover.
Remove the fuel injectors and the wire harness.
Using the 8 mm bolts supplied with the tool. mount
the two uprights to the cylinder head at the end
camshaft holders. The uprights fit over the cam-
shaft as shown.
lnsert the cross shaft through the top hole of thetwo uprights.

6. Select the 7/8 in diameter short compressor attach-ment, and fasten the attachment to the No. 4 hole of
the leve. arm with the speed pin supplied.
8.
7.lnsert an air adapto. into the spark plug hole. pump
air into the cylinder to keep the valve closed whilecompressing springs and removing the valve keepers.
Put shop towels over the oil passages to prevent
the valve keepers from falling into the cylinder
neao.
OIL PASSAGES
Position the lever arm under the cross shaft so thelever is perpendicular to the shaft and the compres-
sor attachment rests on top of the retainer for thespring being compressed. Use the front position
slot on the lever as shown.
