| + | |||
| + | From 1994-later the Clutch Inspection Cover (AKA: Derby Cover) has had a sealing ring, often referred to as the Quad-Ring. It is circular, but its cross-section profile is not round like an o-ring, but rather four-sided flat. The quad-ring P/N is 25463-94A.\\ | ||

Impact-type sockets may be too thick to fit. Metric equivalents that my work are 28mm and 30mm sockets. |

| - | When lossening or tightening these nuts, you will need to **lock the hub & sprocket** - Do not wedge the chain. | + | To remove the Transmission Main Shaft Nut (in the Clutch Hub), you need to remove the Clutch Release Assembly while the Clutch is still assembled. This keeps the Hub locked to the basket. The primary locking tool is used to keep the basket from rotating and therefore the nut can be removed from the hub while the clutch plates prevent the hub from rotating. |

| A closed 4" BRASS hinge also works well to lock the sprockets and then you can use a pull bar and sockets / socket wrench. \\ | A closed 4" BRASS hinge also works well to lock the sprockets and then you can use a pull bar and sockets / socket wrench. \\ | ||
