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.
(11) Install glow plugs (Refer to 8 - ELECTRICAL/
IGNITION CONTROL/GLOW PLUG - INSTALLA-
TION).(12) Install engine cover (Refer to 9 - ENGINE -
