Replace any components severely damaged or worn.INSTALLATION:If either the gear wheel or pinion needs to be replaced, replace both. Timingmarks on the small pinion must be aligned with the keyway on the taperedshaft. The timing marks on the gear wheel must be aligned with the mark onthe small pinion. Failure to heed this caution can damage equipment.1Slide pinion (11) onto camshaft. Install new lock washer (10) and hexagon nut (9) and tighten securely.2Install disc (8) into timing cover housing with graphite side of disc (8) facing outward.3Lubricate dry bushing in timing cover housing with grease (Item 3, Appendix B).4Install gear wheel (6) into dry bushing and secure gear wheel (6) with stud (7).5Install oil seal (5) and needle shell (4) onto gear wheel (6).6Fill housing (2) with 3-1/2 ounces (110 g) of warm grease (Item 4, Appendix B).
