Steering systems on loader backhoes with Serial Numbers 235786 thru 235999 have two
steering cylinders. Loader backhoes with Serial Numbers 319995 thru 342573 have one
steering cylinder. Both steering systems operate the same way. Steering system for
loader backhoes with Serial Numbers 319995 thru 342573 is shown.
Allows operator to steer loader backhoe by direct mechanical link through steering shaft to steering valve.
Provides direct mechanical link between steering wheel and steering valve.
Consists of rotary spool and sleeve assembly in housing with gerotor gear set at one end.
Controlled by steering wheel by direct connection through steering shaft.
Directs flow of high pressure hydraulic fluid to one end of steering cylinder and routes return hydraulic fluid from
other end back to transmission case sump.
When high pressure hydraulic fluid is not available, such as when engine stalls, gerotor gear becomes hand-
operated pump, forcing hydraulic fluid through system to provide manual steering.
