NOTICE:
Check the drive belt deflection at the specified point.
When installing a new belt, set its tension value as
specified.
When inspecting the belt which is used over 5 min-
utes, apply the specifications of ºUsed Belt.º
When reinstalling the belt which is used over 5 min-
utes, adjust its deflection and tension to the medium
value in each specification of ºUsed Belt.º
V±ribbed belt tension and deflection should be
checked after 2 revolutions of engine cranking.
When using a belt tension gauge, confirm the accura-
cy by using a master gauge first.
(b) Inspect generator V belt. (1) Check that the tension indicator is within range A onthe auto tensioner scale.
If the tension is not within the A range, replace the belt with a
new one.
HINT:
When replacing the drive belt with a new one, the belt tension
should be within the B range.

6.INSPECT ENGINE IDLE SPEED
(a)Using SST, connect a tachometer test prove to terminal
9 (TAC) of DLC3.
SST09843±18040
(b)Check the idle speed. Idle speed: 750 to 850 rpm
NOTICE:
Check the idle speed with the cooling fan OFF.
Switch off all accessories and air conditioning before
connecting the test prove to the terminal.
7.INSPECT MAXIMUM SPEED
(a)Start the engine.
(b)Depress the accelerator pedal to the limit.
(c)Check the maximum speed. Maximum speed: 5,100 to 5,250 rpm
8.INSPECT COMPRESSION
(a)Warm up the engine to normal operating temperature,and stop the engine.
(b)Remove the glow plugs. (See page 19±33)
(c) Disconnect the injector connectors.
(d) Inspect cylinder compression pressure.
(1) Install SST (attachment) to the glow plug hole.

(2) Connect SST (compression gauge) to the SST (at-
tachment).
SST 09992±00025 (09992±00211)
(3) Fully open the throttle valve, and start the engine.
(4) While cranking the engine, measure the compres-
sion pressure.
NOTICE:
Always use a fully charged battery to obtain engine
speed of 250 rpm or more.
Check other cylinder compression pressure in the
same way.
This measurement must be done in as short a time as
possible.
Compression pressure:
2,628 kPa (26.8 kgf/cm
2, 381 psi) or more
Minimum pressure:
2,157 kPa (22.0 kgf/cm
2, 312 psi) or more
Difference between each cylinder:
490 kPa (5.0 kgf/cm
2, 71 psi) or less
(5) If the cylinder compression is low, pour a small
amount of engine oil into the cylinder through the
glow plug hole and inspect again.
HINT:
If adding oil raises the compression, there are chances of
the piston rings and/or cylinder bore wear or damage.
If pressure stays low, a valve may be sticking or seating
improperly, or there may be leakage past the gasket.
