PHASING PROBLEMS
Creeping
Air in the hydraulic system
A. Hose vibrating/squealing
B. Control valve shuddering
C. Lag in cylinder movement
D. Creeping when load is applied
By-passing of the piston
A. Both cylinder move together until Master
is on depth stop then Slave stops
Check valve or Tractor valve leaking
B. Both cylinders creep, Master cylinder stops
when it hits the depth stop but the slave continues
Master cylinder piston by-passing (1)
C. Master cylinder retracts but the slave extends
slightly
Master cylinder piston by-passing (2)
D. Master cylinder stationary but not on depth
stop, Slave creeps in
Slave cylinder piston by-passing
Cylinder moving at different rates
Cylinders connected the
wrong way around
They should be connected in series so that the rod end of the larger cylinder is connected to the base of the
smaller cylinder
