1. Adjustment of the control lever
(1)Perform idling with the speed lever (a) contacting the pushrod (b) At this time, confirm that the spring (c) is not compressed by speed lever (a)'s operating torque.
(2)To set the stop position, compress spring (c) using the speed lever (a) and adjust the rack so that it contacts the guide screw at position L1. Then, set and fix using the lock nut (e).
Adjust rack position at this time using shim (f).
(3)After pulling the speed lever (a) in the stop direction and releasing it, confirm that it returns to the idle position.

Information:
Start By:a. remove valve covers 1. Use tooling (A), and disconnect fuel line (1) at each end. Remove the fuel line from the engine. 2. Use tool (B), and remove retainer (2) from the adapter.3. Remove the fuel injection nozzles with tooling (C) as follows:a. Install the 6V6983 Adapter and the 8T3199 Screw into nozzle assembly (3).b. Install the 8T3198 Tube over the 8T3199 Screw.c. Use the 1B4206 Nut on the 8T3199 Screw.d. Use the 1B4206 Nut on the 8T3199 Screw to pull the fuel injection nozzle from the adapter.4. Remove compression seal (4) and carbon dam seal (8) from fuel injection nozzle (3).5. Use tool (D), and remove adapter (6) from the cylinder head.6. Remove gasket (7) and seal (5) from adapter (6). The following steps are for installation of the fuel injection nozzles and adapters.7. Use tool (E) to clean the bore in adapter (6). Use an open end wrench or tap driver to turn tool (E).8. Inspect seal (5) for damage or wear. Replace the seal if necessary.9. Put washer (7) and seal (5) in position on adapter (6).10. Put liquid soap in the bores of the cylinder head and on seals (5) in the adapters.11. Put 5P3931 Anti-Seize Compound on the threads of adapter (6), and install the adapter in the cylinder head assembly.12. Use tool (D), and tighten the adapter to a torque of 205 14 N m (150 10 lb.ft.).
Make sure the correct compression seal washer (4) is used when the nozzle assembly is installed in the adapter. Only copper washers are to be used with this adapter.
13. Install compression seal washer (4), and use tool (F) to install carbon dam seal (8) on the fuel injection nozzle.14. Put fuel injection nozzle (3) in position in the adapter, and install retainer (2).15. Use tool (B) to tighten retainer (2) to a torque of 48 7 N m (35 5 lb.ft.).16. Install fuel line (1). Tighten the nuts on the fuel line with tooling (A) to a torque of 40 7 N m (30 5 lb.ft.).End By:a. install valve covers
