It is useful so you can oil the top shaft bearing (the fastest spinning and hardest working one in the grearbox) without taking the box apart, the other side can easliy be accessed when the slipper plate is off..

It also makes removing that bearing easier too which was its main purpose.......

It's also brilliant for the bearing to be able to ingest the maximum amount of dirt and crud when driving in dusty conditions.

A piece of tape over it gets rid of that problem...

Never thought about oiling the bearing...

Principal reason is EZ bearing removal. We use a rubber sealed bearing and running on all dusty U.SA. tracks have no issues.

Do you guys really have a problem with this? I've (obviously) used every variant of X6 transmission each of which has the hole and never had a single issue with a layshaft bearing. It's within the shell so there's surely not that much dust that gets about.

On grass or astroturf it isn't. It's when you drive on dusty clay-type stuff that dust works it's way into the transmission.

Not a major problem though as a piece of tape keeps everything out.
