AGITATORSHAFTGEARFORKAGITATORGEARThe illustration above shows the gearcase assemblyafter the pulley has been removed and the coverraised prior to complete disassembly.SECTORGEARSince the sector gear meshes with the agitator gear,this gear will turn first in one direction and then inthe other.The main drive pinion meshes with the main drivegear, which is mounted on a one-inch diameter stud.CONNECTINGRODMAIN DRIVEGEARSECTORGEARThe main drive gear is coupled to the sector gear (thesection of a total gear), by means of a heavy steelconnecting rod. Therefore, as the main drive gearrotates the sector gear oscillates.To begin agitation, the agitator gear fork will movedownward, causing two of the slots in the bottom ofthe agitator gear to engage the drive pin in theagitator shaft. Thus, the agitator shaft will oscillateas the sector gear moves the agitator gear, providingthe washing action (or agitation).Both the agitator shaft and the gear-fork shaft areequipped with compression springs which constantlyexert a downward pressure. The agitator gear fork israised by means of the agitate cam bar. This actiondisengages the agitator gear from the drive pin inthe shaft, stopping the action.The agitate cam bar is mounted on top of the gearcaseand is controlled by the plunger which moves up anddown in the agitator solenoid.4
