INSTALLATION SERVICE POINTS
 
 
>>A<< O-RING INSTALLATION
1. Apply a small amount of new engine oil to the O-ring.
2. While turning the fuel injector to right and left, install the O-ring to the fuel injector with care to avoid damage to the O-ring.
 

 
 
>>B<< O-RING INSTALLATION
1. Apply a small amount of new engine oil to the O-ring.
2. Using special tool MB992106, install the fuel injector paying attention to avoid damage to the O-ring.
 

 
 
>>C<< FUEL INJECTOR ASSEMBLY INSTALLATION
1. Apply a small amount of new engine oil to the O-ring.
2. Turning the fuel injector assembly to right and left, install it to the fuel rail with care not to damage the O-ring. After the installation, check for its smooth rotation. At this time, check that the projection part of the fuel injector assembly is in the center.
3. If the rotation is not smooth, the O-ring may be caught. Remove the fuel injector assembly and check the O-ring for damage. After this, re-insert it to the fuel rail and check for its smooth rotation.
 

 
 
>>D<< FUEL INJECTOR SUPPORT INSTALLATION
Install the fuel injector support to the fuel injector groove and fuel rail brim, and fix the fuel injector assembly and fuel rail.
 

 
 
>>E<< FUEL RAIL AND FUEL INJECTOR ASSEMBLY INSTALLATION
1. Apply a small amount of new engine oil to the O-ring at the end of fuel injector assembly.
2.
cautionWhen installing the fuel rail and fuel injector assembly to the cylinder head, take care not to damage the O-ring at the tip of the fuel injector assembly.
Install the fuel rail and fuel injector assembly to the cylinder head. Be careful not to damage the O-ring.
3. Tighten the fuel rail mounting bolts to the specified torque.
Tightening torque: 14 ± 3 N·m (124 ± 26 in-lb)
