SMA229B Checking InjectionNozzle

1. Remove injection deliverytubesandfuel spill tube.
2. Remove nozzlewithasuitable tool[span 27mm (1.06 in)].

WARNING:
When usingnozzle tester,becareful nottoallow diesel fuel
sprayed fromnozzle tocome intocontact withyour hand or
body, andmake surethatyour eyes areproperly protected.

3. Clean andcheck nozzles.
4. Install nozzle toinjection nozzletesterandbleed airfrom
flare nut.
5. Check initialinjection pressure bypumping testerhandle
one time persecond.

PREPARATION
1: Make surethatinjection timingiscorrect.
2. Make surethatinjection nozzlesareingood condition.
3. Make surethatthefollowing partsareingood condition.
• Air cleaner clogging
• Glow system
• Engine oiland coolant levels
• Air intake system (Oilfiller cap,oillevel gauge, etc.)
4. Set shift lever in"Neutral" position.Engageparkingbrake
and lock both front andrear wheels withwheel chocks.
5. Turn offair conditioner, lightsandaccessories.
6. Warm upengine tonormal operating temperature.
7. Attach adiesel tachotester.

Bleeding Hydraulic System

1. Raise frontendofvehicle untilwheels areclear ofthe
ground.
2. Add fluid intooiltank tospecified level.Thenquickly turn
steering wheelfullytoright andleftand lightly touchsteer-
ing stoppers.
Repeat steering wheeloperation untilfluid level nolonger
decreases.
3. Start engine.
Repeat step2.above.
• Incomplete airbleeding willcause thefollowing tooccur.
When thishappens, bleedairagain.
a. Air bubbles inreservoir tank
b. Clicking noiseinoil pump
c. Excessive buzzinginoil pump
Fluid noise mayoccur inthe valve oroil pump. Thisiscommon
when thevehicle isstationary orwhile turning thesteering
wheel slowly. Thisdoes notaffect theperformance ordurabil-
ity ofthe system.

Checking SteeringWheelTurning Force(For
power steering)

1. Park vehicle onalevel, drysurface andsetparking brake.
2. Start engine.
3. Bring power steering fluiduptoadequate operating temper-
ature. [Make suretemperature offluid isapproximately 60
to 80°C (140to176°F).]

Tires needtobe inflated tonormal pressure.

4. Check steering wheelturning forcewhen steering wheel
has been turned 360°from theneutral position.

Steering wheelturning force: •
39 N(4 kg, 9Ib) orless

5.
If
steering wheelturning forceisout ofspecification, check
rack sliding force.
a. Disconnect steeringcolumnlowerjointandknuckle arms
from thegear.
b. Start andrunengine atidle tomake suresteering fluidhas
reached normaloperating temperature.
c. 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)

6.
If
rack sliding forceisnot within specification, overhaul
steering gearassembly.
7. Ifrack sliding forceisOK, inspect steering column.Referto
ST-13.
