ENGINE UNIT DISASSEMBLY

Note

When replacing the injectors (including shuffling the injectors between the cylinders), common rail or cylinder head, it is necessary to replace the injection pipes with new ones.
When replacing the fuel supply pump, common rail, cylinder block, cylinder head, cylinder head gasket or timing gear case, it is necessary to replace the fuel inlet pipe with a new one.
When replacing the fuel injector, check that the injection compensation codes of the fuel injector installed on each cylinder match the ones registered in the ECM. If they do not match, correct the registration details. Click here
