Specification for 384-4705 Fuel Injection Pump Gp 
Item  Qty  Part  Specification Description 
Prior to installation of the fuel injector group, lubricate the bore in the cylinder head with 1P-0808 Multipurpose Grease. Use injector clamp (3) to press the injector into the bore. Do not tap on the top surface of the injector. 
361-9354 Fuel Injection Valve Assembly  Use the following procedure in order to tighten the fuel injection valve assembly:
Before assembly, lubricate the bore and the threads with 1P-0808 Multipurpose Grease.
1. Tighten the valve assembly to 35 N·m (26 lb ft).
2. Turn to reach the final turn angle of 19 ± 1 degrees.
3. Again, tighten to 115 to 290 N·m (85 to 214 lb ft)
7F-8698 Bolt  Torque to 65 ± 7 N·m (48 ± 5 lb ft)
Timing dimension is 64.34 ± 0.20 mm (2.533 ± 0.008 inch) 
230-9456 Unit Injector Nozzle  Use the following procedure in order to tighten the unit injector nozzle:
1. Tighten the unit injector nozzle to 30 N·m (266 lb in).
2. Turn to reach the final turn angle of 58 ± 2 degrees.
3. Again, tighten to 180 to 340 N·m (133 to 251 lb ft)
