1. When the right stabilizer control lever is pushed to the forward to set to the "SHRINK" position. the spool (5) of the
stabilizer LH control valve (2) moves to the left, which forms oil passage between bridge passage (3) and
84 port,
and between
A4 port and T port.
2. The pressure-fed oil from the P port opens the load check valve (4), and flows to 84 port to retract the left stabilizer
cylinder.
3. Return oil from the left stabilizer cylinder returns to the transmission case through the
A4 port, low pressure
passage and T port.
