Operation Description

Heavy steering

(1) The oil supply to the gear oil pump is

insufficient, or the gear oil pump leaks inside

or the filter screen in the steering oil tank is

blocked. The steering is light at low speed

and heavy high at high speed

(2) Erratic steering cylinder movement when

the steering wheel is turned

(3) The oil level in the steering oil cylinder is

too low

(4) The spring tension in the relief valve has

weakened, or the steel ball is not seated

correctly. With a light load the steering is

light but the steering becomes heavier as the

load increases

(5) Oil viscosity is too thick

(6) Steel ball check valve in the valve body

has failed. The steering is heavy when

turning slowly or weak when turning sharply

(7) Oil leakage from the steering system, both

inside and outside

(8) Air in the steering system

(1) Check the gear oil pump.

Clean the filter screen

(2) Bleed the air from the system

and check whether there is air or

an air leak in the oil suction pipe

(3) Fill oil to specified height,

clean the relief valve and adjust

the spring pressure in the

relief valve

(4) Replace defective relief

valve components

(5) Drain oil and replace with the

specified oil

(6) Replace valve

(7) Troubleshoot to find the

location of the oil leak and repair

or replace leaking components

(8) Bleed air from steering system

Steering fails

(1) The king pin is broken or deformed

(2) Rotor and linkage shafts are improperly

mounted or misaligned

(3) Steering cylinder or piston seal ring

is damaged

(1) Replace the king pin

(2) Refit and realign

(3) Replace the piston or the

seal ring

Power steering fails

(1) The clearance between the rotor and the

stator on the pump is too large

(2) During power steering, the driver cannot

feel the endpoints of the extreme steering

positions. During manual steering, the

steering wheel turns but the steering cylinder

does not move

(1) Replace the pump

(2) Replace the seal ring on

the piston

Steering is slow to

respond or hard to turn

(1) The clearance between the valve core and

the valve housing is too large

(2) The clearance between the interlocking

shaft and the fork pin is too large

(3) The clearance between the interlocking

shaft and the rotor is too large

(4) The return spring is broken or too soft

(1) Replace

(2) Replace

(3) Replace

(4) Replace
