Adjustment (Cont'd)

6. Move rackover itsentire stroke several times.
7. Measure pinionrotating torquewithintherange of180° from
neutral position.
Stop thegear atthe point ofmaximum torque.
8. Loosen adjusting screw,thenretighten itto 4.9 N'm (50
kg-em, 43in-Ib).
9. Loosen adjusting screwby70° to110°.

10.Prevent adjusting screwfromturning, andtighten locknut
to specified torque.

Check racksliding forceonvehicle asfollows:
a. Install steering gearontovehicle, butdonot connect tie-rod
to knuckle arm.
b. Connect allpiping andfillwith steering fluid.
c. Start engine andbleed aircompletely.
d. Disconnect steeringcolumnlowerjointfrom thegear.
e. Keep engine atidle and make suresteering fluidhas
reached normaloperating temperature.
f. Pull tie-rod slowlytomove itfrom neutral position to
:l:
11.5
mm
(:l:
0.453 in)atspeed of3.5 mm (0.138 in)/s.Check that
rack sliding forceiswithin specification.

Average racksliding force:
152.0 -240.3 N(15.5 .24.5 kg,34.2.54.0 Ib)
Maximum forcedeviation:
98 N(10 kg,22Ib)

g. Check sliding forceoutside aboverangeatrack speed of40
mm (1.57 in)/s.

Maximum racksliding force:
294 N(30 kg, 66Ib)
Maximum forcedeviation:

147 N(15 kg, 33Ib)

• Ifrack sliding forceisnot within specification, readjustby
repeating adjustment procedurefromthebeginning.

• If
rack sliding forceisstill outofspecification after
readjustment, gearassembly needstobe replaced.
