1. When the right stabilizer control lever is pulled to the downward to set to the "EXTEND" position, the spool (5) of
the stabilizer
RH control valve (2) moves to the right, which forms oil passage between bridge passage (6) and A3
port, and between
83 port and T port_
2. The pressure-fed oil from the P port opens the load check valve (3), and flows to A3 port to extend the right
stabilizer cylinder.
3. Return oil from the right stabilizer cylinder returns to the transmission case through the 83 port, low pressure
passage and T port.
