DRIVE BELTS
4. Remove drive belt.
 Turn drive belt auto-tensioner adjusting bolt clockwise to
release drive belt tension.
INSTALLATION
1. Install the drive belt.
CAUTION:
 Make sure drive belt is correctly engaged with the pulley
groove.
 Check for oil and coolant on drive belt and each pulley
groove.
 Certain drive belts have five teeth whereas the air condi-
tioning compressor pulley, power-assisted steering pump
pulley, and generator pulley all have six teeth.In this case,
it is essential to check that inner tooth (O) of the pulleys
remains free when fitting the drive belt.
Never turn the engine in the opposite direction to its nor-
mal operating direction.
Use a brush to remove any deposits from the crankshaft
pulley V grooves.
2. Release drive belt auto-tensioner, and apply tension to drive belt.
3. Turn crankshaft pulley clockwise several times to equalize tension between each pulley.

CAMSHAFT VALVE CLEARANCE
CAMSHAFT VALVE CLEARANCE
Inspection and AdjustmentINFOID:0000000001381465
INSPECTION
1. Place the valves of the cylinder concerned at the “end of
exhaust - beginning of intake” position and inspect the clearance
(X).
NOTE:
Dimension (Y) corresponds to the tappet thickness sizes (there
are 25 sizes available).
2. Compare the values recorded with the values specified, then
replace the tappets which are not within tolerance.
ADJUSTMENT
1. The camshaft must be removed to replace the tappets after
determining dimension (Y).
2. Set up the following assembly using dial gauge stand
[KV113B0050 (Mot. 252-01) (commercial service tool) or equiva-
lent tool] and dial gauge, then calibrate the gauge.
3. Raise the gauge extension (without modifying the position of the
magnetic support/gauge assembly), then slide in the tappet to
be measured.
Note dimension (Y) and repeat the operation for the tappets
where the valve clearance is not within tolerance.
Select the various thicknesses of the tappet(s). 25 sizes of sin-
gle-piece tappets are available. Refer to EM-333, "
Camshaft". Clearance when the
engine is cold: Refer to EM-333, "
Cam-
shaft".MBIB0333E

COMPRESSION PRESSURE
InspectionINFOID:0000000001381466
1. Warm up engine thoroughly. Then stop.
2. Remove glow plug.
3. Disconnect high-pressure supply pump harness connector to avoid fuel injection during measurement.
4. Connect compression gauge attachment hose [SST:
KV113B0400 (Mot. 1592)] (A) to the hole for glow plug.
5. Connect compression gauge (B) to attachment hose (A).
6. Turn ignition switch to START for cranking and check compres-
sion gauge.
7. Perform the same procedure for the other cylinders.
 If compression pressure is below minimum value, check valve
clearances and parts associated with combustion chamber (valve, valve seat, piston, piston ring, cylin-
der bore, cylinder head, cylinder head gasket). After checking, measure compression pressure again.
 If any cylinder has low compression pressure, pour a small amount of engine oil into the glow plug hole
of the cylinder to re-check it for compression.
- If the added engine oil improves the compression, piston rings may be worn out or damaged. Check pis-
ton rings and replace if necessary.
- If the compression pressure remains at low level despite the addition of engine oil, valves may be mal-
functioning. Check valves for damage. Replace valve or valve seat accordingly.
 If two adjacent cylinders have respectively low compression pressure and their compression remains
low even after the addition of engine oil, cylinder head gaskets are leaking. In this case, replace cylinder
head gaskets.
8. Disconnect compression gauge (B) and attachment hose (A).
9. After inspection is completed, install removed parts.
10. Start the engine, and make sure that the engine runs smoothly.
11. Perform trouble diagnosis. If DTC appears, erase it. Refer to EC-1043, "
BASIC INSPECTION : Descrip-
tion". Compres-
sion pres-
sure: Refer to EM-333,
"GeneralSpecification".
