SYMPTOM
8. Car pulls to one side or the other
9. Momentary increase in effort
when turning wheel quickly to
right or left
Heavy steering
POSSIBLE CAUSE
8. (a) Front end geometry misaligned
(b) Pump drive
belt@) slipping
(c) Flow control valve sticking
9. (a) Low fluid level in reservoir
(b) Pump drive
belt@) slipping
(c) Heavy internal fluid leak
10. (a) Incorrect tyre pressures
(b) Loose pump drive
belt(s)
(c) Low fluid level in reservoir
(d) Lack of lubricant in steering
joints
(e) Insufficient fluid pressure
(f) Faulty or obstructed flow con-
trol valve
(g) Incorrect front wheel alignment
I Q Excessive castor or toe-in
(i) Incorrect camber angle
(j) Rocking shaft gear too tightly
meshed
1
(k) Distorted flexible coupling or
defective universal joint
(1) Triangle levers misaligned
(m) Front sub-frame distorted
(n) Kinks in
hoses
(0) Obstruction in hose. Inner bore
of hose swollen,
caused by over-
heated or incorrect fluid
(p) Pressure loss in steering box
cylinder caused by worn ring or
I
scored bore
(q) Leakage at valve rings or valve
body to worm seal
ACTION
1
8. (a) Check steering geometry
(b) Correctly adjust steering pump
belt(s)
(c) Examine flow control valve. Re-
new valve if necessary
9. (a) Ch~k fluid level.
Top-up if
requued. Examine system for
leaks
Correctly
belt(s)
adjust
drive
(c) Check pump outlet pressure. If
pressure is low renew combined
flow control and relief valve. If
pressure remains low, check
system for internal leaks by
dismantling steering box
10. (a) ~h&k and correct tyre pressures
(b) Correctly adjust drive
belt@)
(c) Check level of fluid in reservoir.
Top-up if required. Examine
system for leaks.
(d) Examine all steering joints.
Grease with approved lubricant
if required
(e) If the preceding checks do not
reveal the cause of heavy steering
check pump pressure
(f
) Renew or replace if necessary
(g) Check and adjust if required
Q Adjust castor or toe-in to with-
in specified limits
(i) Correct camber angle to
within
specified limits
I (j) Disconnect track rods at steering
arm. Check steering for stiffness.
I Adjust gear mesh if required
1
(k) Examine flexible coupling. Re-
new if necessary. Examine uni-
versal joint in lower steering
column. Renew if necessary
(l) Check wheel castor and camber
(m) Check sub-frame for correct
alignment. required Correct or renew if
(n) Ensure correct run of hoses
(0) Renew hose
(p) Overhaul steering box
(q) Overhaul steering box
