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.

Adjustment of the rack sensor (-2320)
1. Rack limit adjustment
(1)After mounting the joint (B), select the shim (D) so that the rack position is in the rack limit position.
(2)Install the rod (e) to the block (c).
(3)At the rack limit, set the distance between the pump end face and the rod (E) to L1.
2. Rack sensor
(1)Screw in the bobbin (A) until it contacts the joint (B).
(2)Fix the speed control lever at the full side and set the pump speed at N1.
(3)Adjust the depth that the bobbin (A) is screwed in so that the control unit's rack sensor output voltage is VR+-0.01 (V), then tighten the nut (F). (If equipped with a boost compensator, perform with boost pressure applied.)
(4)Adjust the bobbin (a) so that the rack sensor output voltage becomes VR +-0.01(V).

This is a 1-hour job.
All Group 3 Affected Product
This is a .3-hour job. Submit a supplemental claim for Group 3 if a claim for Group 1 or 2 has already been submitted.
Parts Disposition
Handle the parts in accordance with your Warranty Bulletin on warranty parts handling.
Attach. (1-Rework Procedure)Rework Procedure
Refer to the following instructions and illustrations. Replace the existing fuel lines and their related parts with the new fuel line groups.
To insure correct clamp locations, install left and right fuel line groups as assembled. However, if clamps are removed, mark locations to insure correct positions when reassembling.
On the 992C Wheel Loader, it is necessary to remove the 6N8322 Air Outlet Tube Assembly to be able to install the right bank fuel line group.
Tighten the fuel line clamp screws to a torque of 2.25 N m (20 lb in). Do not over tighten. Use a 6V6069 Torque Screwdriver or similar tool to tighten the screws.
Group 1 Procedure
1. Clean and paint the new 6I0361 and 7E3539 Fuel Line Groups before proceeding to the job site.A) "Tape Off" the number 3, 5, and 6 fuel lines in the area of the tower clamp. (See Illustration 1 - Part 4 of 5, Section C-C)B) Install 5F2807 Plastic Caps and 2F2990 Plastic Plugs on the ends of the fuel lines.C) Clean and paint the fuel line groups.D) After drying completely, remove the tape. Do not remove the plastic caps and plugs until the fuel lines are ready to be installed on the engine. Transport the fuel line groups in their original boxes.2. Remove all mounting bolts from the fuel line brackets at the aftercooler housing. Except for the tower clamp assembly, new mounting bolts and washers will be used. Keep the washers. The washers may be needed later as spacers.3. A) Disassemble the tower clamp assembly behind the fuel injection pump. The 9Y3356 Clamp and 9Y3359 Clamp As. that form the tower clamp will be reused. (See Illustration 1 - Part 4 of 5, Section C-C)B) Disconnect the 2 line clamps from the 9Y3361 Bracket (Front V Bracket).C) Disconnect the 6 line clamps from the 7E5779 Bracket (Large V Bracket).4. Disconnect all the fuel lines at the fuel injection pump and at the adaptors in the valve cover bases.5. A) Remove the left and right side fuel line groups as separate assemblies.B) Remove the 9Y3361 Bracket (Front V Bracket). Replace it with a new 6I0347 Bracket.6. Remove the plastic caps and plugs from the fuel lines. Set the new 6I0361 Fuel Lines Group (left side) and the new 7E3539 Fuel Lines Group (right side) in place and hand tighten the fuel nuts. (See Illustration 1 - Part 1 of 5). If any of the ends of the individual fuel lines are not square with the bonnets in the fuel injection pump or with the adaptors in the valve cover bases, gently bend the lines by hand to align the
