FOR ALL OF VEHICLES
PRECAUTION
1. FOR VEHICLES EQUIPPED WITH SRS AIRBAG
(a) The TOYOTA T100 is equipped with an SRS (Supple-
mental Restraint System), such as the driver airbag.
Failure to carry out service operations in the correct se-
quence could cause the supplemental restraint system to
unexpectedly deploy during servicing, possibly leading to
a serious accident.
Further, if a mistake is made in servicing the supplemental
restraint system, it is possible the SRS may fail to operate
when required. Before servicing (including removal or
installation of parts, inspection or replacement), be sure
to read the following items carefully, then follow the cor-
rect procedure described in this manual.
(b) GENERAL NOTICE
(1) Malfunction symptoms of the supplemental re-
straint system are difficult to confirm, so the diag-
nostic trouble codes become the most important
source of information when troubleshooting. When
troubleshooting the supplemental restraint system,
always inspect the diagnostic trouble codes before
disconnecting the battery (See page DI−365).
(2) Work must be started after 90 seconds from the
time the ignition switch is turned to the ”LOCK” posi-
tion and the negative (−) terminal cable is discon-
nected from the battery.
(The supplemental restraint system is equipped
with a back−up power source so that if work is
started within 90 seconds of disconnecting the neg-
ative (−) terminal cable from the battery, the SRS
may deploy.)
When the negative (−) terminal cable is discon-
nected from the battery, memory of the clock and
audio systems will be cancelled. So before starting
work, make a record of the contents memorized by
the each memory system. Then when work is fin-
ished, reset the clock and audio systems as before.
To avoid erasing the memory of each memory sys-
tem, never use a back−up power supply from out-
side the vehicle.
(3) Even in cases of a minor collision where the SRS
does not deploy, the steering wheel pad should be
inspected (See page RS−9).

in a vise.
NOTICE:
Be careful not to damage the camshaft.
(b) Install these parts:
(1) Camshaft gear spring
(2) Camshaft sub−gear
(3) Wave washer
HINT:

4. INSTALL CAMSHAFTS
NOTICE:
Since the thrust clearance of the camshaft is small, the
camshaft must be kept level while it is being installed. If the
camshaft is not kept level, the portion of the cylinder head
receiving the shaft thrust may crack or be damaged, caus-
ing the camshaft to seize or break. To avoid this, these
steps should be carried out.

8. SET CHAIN TENSIONER
Turn the crankshaft to the left so that the hook of the chain ten-
sioner is released from the pin of the plunger, causing the plung-
er to spring out and the slipper to be pushed into the chain.
HINT:
If the plunger does not spring out, press the slipper into the
chain tensioner with a screwdriver or your finger so that the
hook is released and the plunger springs out.
9. CHECK VALVE TIMING
(a) Turn the crankshaft pulley, and align its groove with the
timing mark ”0” of the timing chain cover.
NOTICE:
Always turn the crankshaft clockwise.
(b) Check that the timing marks (1 and 2 dots) of the camshaft
drive and driven gears are in straight line on the cylinder
head surface as shown in the illustration.
If not, turn the crankshaft 1 revolution (360°) and align the
marks as above.
