Trouble, External Symptoms
Remedy
Enhanced Instability of Front Wheels
Warm tightening nut slackened.
Tighten up the nut to 2 kgf•m, back it off 1/6 turn, and
secure with a cotter-pin.
Increased play in front wheel bevel bearings or
steering rod joints.
Adjust, as required.
Slackened nuts attaching the pitman arm, sector,
and steering knuckle tie-rods.
Tighten up the nuts.
Increased axial displacement of the turn shaft
Adjust the fault.
Enhanced Play of the Steering Wheel
Enhanced clearance in the «worm-sector» mesh-
ing.
Adjust, as required.
Enhanced play in universal-joint connections in
the steering wheel drive.
Replace worn-out parts.
Worm nut slackened
Tighten up the nut.
10.3.1. HYDROSTATIC STEERING CONTROL
Enhanced Steering Wheel Effort
Lack of, or insufficient, oil pressure in the steering
wheel hydraulic system. Delivery pump faulty.
Have it repaired or replace the pump.
Insufficient oil level in the oil tank.
Fill up the tank to the required level.
Wedging-up of the steering-wheel cardan splined
tail-piece in the metering pump driving shaft
Locate wedging-up and remove.
Substantial friction in mechanical components of
the steering column or FDA reduction gear.
Remove friction.
Steering Wheel Rotates Without Stop
Lack of oil in oil tank.
Fill up the tank to the required level and pump the
system through.
Worn-out seals of the turn cylinder.
Replace with new ones.
Steering Wheel Spontaneous Rotation 2
(«Motoring») With Operator’s Hands Removed
Metering pump spool would not return to
«Neutral» position:
(a) Wedging-up of the steering-wheel cardan
splined tail-piece in the metering pump driv-
ing shaft.
Locate wedging-up and remove.
(b) Substantial friction in mechanical compo-
nents of the steering column.
Remove the cause.
Conflict Between the Steering Wheel Turning Direction and That of Wheels
Incorrect connections of metering pump cylinder
outlets to the turn cylinder.
Change over connections, as appropriate.
