Remove seven screw assemblies (Figure 3, Item 13), cut-away governor cover (Figure 3, Item 21), and gasket (Figure 3, Item 20) from top of governor. 8. On models 5063-5392, 5063-5393, and 5063-539L loosen locknut (Figure 3, Item 16) and screw starting aid screw (Figure 3, Item 15) into gap adjusting screw (Figure 3, Item 17). CAUTION When manually overriding governor, watch engine controls closely and do not allow engine to overspeed. Extended engine operation above speed limits can damage engine. 9. Start and run engine between 1100–1300 rpm by manual operation of differential lever (Figure 3, Item 14). 10. Check gap between low-speed spring cap (Figure 3, Item 18) and high-speed spring plunger (Figure 3, Item 19) with an injector rack gage. Gap should be 0.002–0.004 in. (0.05–0.10 mm). If necessary, set gap again with adjusting screw (Figure 3, Item 17). 11. On model 5063-5299, hold gap adjusting screw (Figure 3, Item 17) and tighten locknut (Figure 3, Item 16). 12. Check gap with engine running between 1100–1300 rpm, adjust gap if necessary. 13. Stop engine by moving differential lever (Figure 3, Item 14) to NO FUEL position. CAUTION Ensure governor stop lever moves injector racks freely to NO FUEL position before installing cut-away governor cover. Any binding of stop lever and injector racks could result in failure to stop a run-away engine. Extended engine operation above speed limits can damage engine. NOTE On models 5063-5392, 5063-5393, and 5063-539L, install cut-away governor cover after starting aid screw adjustment. 14. On model 5063-5299, install cut-away governor cover (Figure 3, Item 21), gasket (Figure 3, Item 20), and seven screw assemblies (Figure 3, Item 13) to governor. Tighten screws securely.
