ADJUSTMENT NOTE Letter “R" or “L" indicates injector location, right or left side, as viewed from rear of engine. Cylinder numbers start at front of each side. Adjust No. 3L or 3R injector control lever first to establish a guide for adjusting remaining injector control levers. Ensure idle speed adjusting screw is backed out or a false fuel injector rack setting will result. Adjust injector control tubes with the same governor cover used on governor to ensure proper injector control tube adjustment. 3. Loosen idle speed locknut (Figure 6, Item 21). Hold locknut and turn idle speed adjusting screw (Figure 6, Item 22) until 1/2 inch of threads project from locknut. CAUTION Cover oil drain hole in cylinder head with clean rag to prevent cotter pin and clevis pin from falling into engine. 4. Loosen six adjustment screw locknuts (Figure 6, Item 29) and back out six adjusting screws (Figure 6, Item 20). All six injector control levers (Figure 6, Item 28) should be loose on control tubes (Figure 6, Item 18). 5. Move linkage (Figure 6, Item 23) connecting governor to control tubes. Linkage must not bind. 6. Rotate clevis pins (Figure 6, Item 24) in right and left control tube levers (Figure 6, Item 25). Pins must rotate freely. 7. Check for slight movement of each control tube (Figure 6, Item 14) between its two brackets (Figure 6, Item 26) to ensure there is no binding. 20 2 21 23 24 25 26 27 28 29 22 14 MAINT_219 Figure 6.
