STANDARD PROCEDURE
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.

(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

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).
