Item  Qty  Part  Specification Description 
Before installation of the unit injector, lubricate the O-ring seals (5) with a 50/50 mixture of clean engine oil and 8T-2998 Lubricant. 
Torque the locknut to 100 ± 10 N·m (74 ± 7 lb ft)
Use the following procedure to tighten the bolt: 
1. Tighten the bolt to 55 ± 10 N·m (41 ± 7 lb ft).
2. Loosen the bolt until the bolt is finger tight.
3. Again, tighten the bolt to 55 ± 10 N·m (41 ± 7 lb ft).
Adjust the unit injector height to 78.0 ± 0.2 mm (3.07 ± 0.01 inch)
