installation torque.
NOTE: Adjustment of Bi--Directional Relief Valve (item
12) is NOT recommended.
NOTE: The CrossTrax
TM
AWD control manifold uses
several zero leak plugs. These plugs have a tapered
sealing surface on the plug head that is designed to re-
sist vibration induced plug loosening. The zero leak
plugs also have an O--ring to provide a secondary seal.
If zero leak plug removal is necessary, lightly rap the
plug head using a punch and hammer before using an
allen wrench to remove the plug: the impact will allow
plug removal with less chance of damage to the socket
head of the plug. When installing plugs into the control
manifold, torque plugs to the values identified in Figures
78.
