(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 (7) Connect compression tester hose adapter #9295 to compression gauge and test compression pressure (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 (10) Remove compression tester and adapter from cylinder head. (11) Install glow plugs (Refer to 8 - ELECTRICAL/ IGNITION CONTROL/GLOW PLUG - INSTALLA- (12) Install engine cover (Refer to 9 - ENGINE - INSTALLATION). COMPRESSION SPECIFICATIONS Maximum Compression 29-35 bar (420-507 psi) Minimum Compression 18bar (261 psi) Permissible Difference ± 3bar (± 44 psi) STANDARD PROCEDURE - CYLINDER LEAK (1) Warm engine to operating temperature.
