Test conditions: A)
1380 +35 kPa applied to control port M
B)
56 to 76 L/min applied lube port L
3.4.18 Reverse operation. The steer unit shall meet the following requirements when the
input shaft is rotated in the reverse direction (CCW rotation as seen when looking at the end of
the shaft).
3.4.18.1 Clutch engagement (reverse rotation). Output shaft speeds shall be as specified
in table III (see 4.6.3.6).
3.4.18.2 Clutch pressures verses steer lever positions (reverse rotation). The relationship
between clutch pressures and steer lever positions shall be as specified in table IV for geared steer
operations, and as specified in table V for clutch brake operations (see 4.6.3.7).
3.4.18.3 Lube pressures versus steer lever positions (reverse rotation). The pressure at
lube port L shall not be less than that specified in table IV for geared steer operations, or that
specified in table V for clutch brake operations (see 4.6.3.7).
