| + | ====== Rear Pivot Shaft ====== | ||
| + | |||
| + | The shoulder on the shaft sits flush with the outside edge of the engine. \\ | ||
| + | The pivot shaft is not a press fit into the bore but there is some tolerances involved. \\ | ||
| + | One the backing plate is removed, the shaft may not easily be pulled out. \\ | ||
| + | You should be able to remove it by simply hitting the opposite end with your hand or rubber mallet (after wiping any rust /debris off the shaft). \\ | ||
| + | The shaft should turn freely once the retainer plate is removed but there is no "play" as the tolerance is close to an interference fit condition. \\ | ||
| + | The shaft is not tapered but there is a shoulder on the shaft and there is a recessed shoulder on the engine itself. \\ | ||
| + | Below is a picture of the clutch side of the rear engine mount and you can see the machined shoulder on the inside. \\ | ||
| + | There is no bushing in the hole, it is just machined through. | ||

| + | On the shoulder of the shaft there are two "flat" spots 180° from each other. The retainer plate has two small tabs that fit into the flat spots. \\ | ||
| + | The shaft can still rotate a small amount until the shoulder on the shaft comes into contact with the tab. \\ | ||
| + | The backing plate has two tabs that engage those flat spots on the pivot shaft and that connection locks the shaft from rotating once installed. \\ | ||
