1. When installing the pre-stroke actuator on the pump, first tighten the installation bolts loosely, then move the actuator fully counterclockwise (viewed from the drive side).
Temporary tightening torque: 1 - 1.5 N.m (0.1 - 0.15 kgf.m)
2. Move the actuator in the clockwise direction when viewed from the drive side, and adjust so that it becomes the adjustment point of the adjustment value. Then tighten it.
Tightening torque: 7^9 N.m (0.7^0.9 kgf.m)
3. After prestroke actuator installation adjustment, simultaneously stamp both the actuator side and housing side.

Introduction
1. Type 2 fuel injector. 2. Two piece follower. 3. Nose cone. 4. Nozzle assembly.Tools are now available for the removal and installation of nose cone (3), on type 2 fuel injectors (1), when it is necessary to replace a nozzle assembly (4). Type 2 fuel injectors can be identified by the two piece follower (2).
5. 1U9395 Plate. 6. 1U8701 Socket.Use 1U9395 Plate (5) with the 6V4830 Fixture Group (not shown) and the procedure given in this instruction, for the removal and installation of nozzle assembly (4).Earlier type 2 injectors have a nose cone that has serrations on its exterior. These serrations will be damaged when the nose cone is removed. A damaged nose cone is not to be used again. A 7C9795 Nose Cone is available for use as a replacement for the original nose cone.The 7C9795 Nose Cone has a hexagon shape on its exterior. This nose cone can be installed and tightened using 1U8701 Socket (6). When the 7C9795 Nose Cone is installed, be sure to tighten it according to the procedure given in this instruction.Removal and Installation of Nose Cone and Nozzle Assembly
1. Remove the original plate from the 6V4830 Fixture Group and install 1U9395 Plate (1).2. Put injector (2) in position on the fixture group. If the exterior of the injector nose cone is a hexagon shape as shown at location (A), use the 1U8701 Socket for nose cone removal. 3. If the exterior of the nose cone has serrations as shown at location (B), use a pipe wrench, as shown, to remove the nose cone. Anytime a pipe wrench is used to remove a nose cone, the nose cone will be damaged. Never use or install a damaged nose cone on an injector. Always install a new 7C9795 Nose Cone as a replacement. 4. After the nose cone has been loosened, use a hammer and 6V4822 Tip Driver (3) to tap the nozzle assembly as shown. This is done to break the connection between the nozzle assembly and the nose cone. Be sure to use only the 6V4822 Tip Driver in this procedure, because use of a standard punch, or any other similar tool will cause damage to the nozzle tip.5. Remove the nose cone and nozzle assembly. 6. Inspect surface (C) in the injector. This is the sealing surface for the nozzle assembly. This surface must be clean and free of any scratches, nicks or burrs. Even a piece of lint from a shop towel can cause a leak and destroy nozzle performance. 7. Remove original O-ring seal (4). Install a new O-ring seal, refer to the Parts Book for the correct part number. Make sure the O-ring seal is not damaged during installation.Use a generous amount of 1P0808 Grease, or a good grade of multi-purpose lubricant, to lubricate the O-ring seal before the nose cone is installed.8. Install new nozzle assembly (5) on the injector. 9. Install and finger tighten the new 7C9795 Nose Cone on the injector. Using a
