290 kPa {3.0 kgf/cm', ,[2 psi]
NOTE: lf the synchronizing piston ooes not move
after applying air pressure; move the primary or
secondary rocker arm up and down manually by
rotating the crankshaft clockwise.
1'1. With the specified air pressure applied, move the
intake primary rocker arm (A) for the No. j cylinder.
The primary rocker arm and secondary rocker arm
(B) should move together.
. lfthe intake secondary rocker arm does
not move.
remove the primary and secondary rocker arms
