GOVERNORSRepair & AdjustmentFig. 15. Vertical ShaftFig. 16. Large Aluminum EnginesRe-AssemblyOn horizontal crankshaft models, the governor rides on ashort stationary shaft and is retained by the governorshaft, with which it comes in contact after the crankcasecover is secured in place. Press governor cup againstcrankcase cover to seat retaining ring on shaft, prior toinstalling crankcase cover. It is suggested that theassembly of the crankcase cover be made with thecrankshaft in a horizontal position. The governor shaftshould hang straight down parallel to the cylinder axis.Fig. 17. If the governor shaft is clamped in an angularposition, pointing toward the crankcase cover, it ispossible for the end of the shaft to be jammed into theinside of the governor assembly, resulting in brokenparts when the engine is started. After the crankcasecover and gasket are in place, install cover screws. Besure that screw "A," Fig. 19, has nonhardening sealanton threads of screw. Complete installation of remaininggovernor linkages and carburetor and then adjustgovernor shaft and lever.Fig. 17. Showing Governor Shaft in Proper PositionOn vertical crankshaft models the governor is part of theoil slinger and is installed as shown in Fig. 18. Models100900 and 130900 use spring washer as shown in Fig.18. Before installing sump be sure that governor cup isin line with governor shaft paddle. Install sump coverand gasket being sure screw "A," Fig. 19 hasnonhardening sealant on threads.Fig. 18. Shows Spring on Camshaft after Governor isInstalled.
