| 7 | Remove fuel injectors (Y76/14, Y76/15, Y76/16, Y76/17). | The fuel injectors (Y76/14, Y76/15, Y76/16, Y76/17) must be stored vertically (connections upward) and must not be laid on their side. This prevents air entering the fuel injectors (Y76/14, Y76/15, Y76/16, Y76/17), which could cause engine starting or running problems when they are reinstalled. Install new sealing rings and coat injector shafts with special grease. Special grease |
