| - | The initial engine feed on 86-90 models is directed straight out of the oil pump into the bottom of the cam cover. \\ | + | |
| - | On 91 and up engines, oil is routed from the oil pump into the oil filter pad and then into a horizontal feed galley in the top of the gearcase. \\ | + | |
| - | This removed the need for the oil to return to the pump from the filter as in 86-90 engines. \\ | + | |
| - | Therefore, the filter return port on the -91 pump was removed. It has only one feed fitting in the front routed to the filter pad. | + | |
| - | There is no gearshaft bushing used in the body or the cover. \\ | + | Oil is routed from the oil pump into the oil filter pad and then into a horizontal feed galley in the top of the gearcase. \\ |
| - | There is a recess inside the body for a gearshaft thrust washer. \\ | + | The oil pump has one feed fitting in the front routed to the filter pad. |
