Rear Cover
WARNING: This page does not describe the selected car, but rather 6 other vehicles, including the 2007 MINI Cooper, 2006 MINI Cooper, 2005 MINI Cooper, 2004 MINI Cooper, and 2003 MINI Cooper. However, it is still accessible from the selected car via links, so may be relevant.
The rear cover is an extension to the main housing providing a housing for 5th gear, 5th gear synchromesh hub and the selector fork. The rear cover also houses an oil trap and guide to supply oil to the hole inside the output shaft. Cross drilled holes in the shaft provide lubrication for the gears. See Fig 1 and Fig 2 .
