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

Make sure that the primary and secondary rockerarms are mechanically connected by the pistonsand that the mid rocker arms do no. move wnenpushed manually.
SECONDARYROCKER ARM
. lf any mid rocker arm moves independently ofthe primary and secondary rocker arms, replacethe rocker arms as a set.
Remove the tools.
Check the operation of the lost motion assembly bypushing on the mid rocker arm. The lost motionassembly should compress fully and operatesmoothly through its full stroke. Replace the assem_bly if it does not work smoothly.
