STANDARD PROCEDURE - COMPRESSION
TESTING ENGINE
(1) Warm up engine to operating temperature
(approx. 80 ÉC, 176ÉF).
(2) Shut off engine.
(3) Remove engine cover (Refer to 9 - ENGINE -
REMOVAL).
(4) Remove glow plugs (Refer to 8 - ELECTRICAL/
IGNITION CONTROL/GLOW PLUG - REMOVAL).
(5) Crank engine several times with the starter to
eliminate combustion residues in the cylinders.
(6) Insert compression tester adapter #8927 (Refer
to 9 - ENGINE - SPECIAL TOOLS) with check valve
installed into glow plug hole of cylinder to be tested.
(7) Connect compression tester hose adapter #9295
to compression gauge and test compression pressure
by cranking engine with starter for at least 8 revolu-
tions.
(8) Carry out test procedure at the remaining cyl-
inders in the same way.
(9) Compare pressure readings obtained with the
specified pressures. If the pressure reading is below
the minimum compression pressure or if the permis-
sible difference between the individual cylinders is
exceeded. Refer to cylinder leak down test.
(10) Remove compression tester and adapter from
cylinder head.
(11) Install glow plugs (Refer to 8 - ELECTRICAL/
IGNITION CONTROL/GLOW PLUG - INSTALLA-
TION).(12) Install engine cover (Refer to 9 - ENGINE -
INSTALLATION).

Permissible Difference
Between Cylinders  3bar (  44 psi)
STANDARD PROCEDURE - CYLINDER LEAK
DOWN TEST
(1) Warm engine to operating temperature.
WARNING: DO NOT OPEN COOLING SYSTEM
UNLESS COOLANT TEMPERATURE IS BELOW 90C
(194ÉF). RISK OF INJURY TO SKIN AND EYES AS A
RESULT OF SCALDING WITH HOT COOLANT
WHICH SPLASHES OUT. RISK OF POISONING
FROM SWALLOWING COOLANT. OPEN CAP
SLOWLY AND RELEASE PRESSURE. STORE COOL-
ANT IN PROPER CONTAINERS ONLY. WEAR PRO-
TECTIVE GLOVES, CLOTHING AND EYE
PROTECTION.
NOTE: Turn cap carefully as far as first detent,
release pressure, then unscrew cap.
(2) Open cooling system cap at coolant recover
pressure container.
(3) Remove engine cover (Refer to 9 - ENGINE -
REMOVAL).
(4) Unscrew oil filler cap.
(5) Remove glow plugs (Refer to 8 - ELECTRICAL/
IGNITION CONTROL/GLOW PLUG - REMOVAL).
NOTE: Crank engine at crankshaft in direction of
rotation of the engine (clockwise).
(6) Position cylinder to be tested to ignition Top
Dead Center (DTC).
NOTE: Calibrate cylinder leak down tester and
remove check valve in screw-in fitting.
(7) Connect cylinder leak down tester and follow
INSPECTING Instruction.
INSPECTING
NOTE: If crankshaft rotates, install retaining lock for
crankshaft/ring gear.
(1) Pressurize cylinder with compressed air and
read off pressure loss at cylinder leak tester. If exces-
sive pressure loss exists, determine possible cause
(Refer to 9 - ENGINE - STANDARD PROCEDURE).

INSTALLATION
INSTALLATION - CYLINDER HEAD
WARNING: (Refer to 14 - FUEL SYSTEM - WARN-
ING)
NOTE: Thoroughly clean all mating surfaces with
appropriate solvents and blow out bolt holes, to
assure that no grease or oil is present during reas-
sembly. If piston or connecting rods have been
replaced, measure piston protrusion. Inspect all cyl-
inder head bolts for defects and stretching before
installation (Refer to 9 - ENGINE/CYLINDER HEAD -
