Deep water wading with the NAS clutch cover

I was replacing the clutch over the other day and I noticed that it doesn't seem to be watertight. For example, there is not very much pressure on the top edge of the clutch plate.

Nothing is holding it vertically, so my slipped down a fraction of an inch during installation, creating what seems to be a very small crack between the top of the clutch plate and bell housing.

Has anyone had this problem before? I was thinking about applying some RTV sealant (avoiding the small drain hole of course) and re-seating the thing.

Hard to follow what you are asking. The "clutch plate" is the friction disc. Are you refering to the bell housing to block fitment, or the small access cover ? It is not meant to be water tight. Given the signifigant swings of temp inside the bellhousing an air tight seal would be a bad idea. The bell housing has a removable "wading plug @ the bottom. This is to be removed after a deep wading to release water that has managed its way in.

Sorry, yes not the clutch plate but the clutch cover (that attaches to the bell housing). Brain fart.

It seems like a significant amount of water, sand, and mud could get in there during water crossings. Mine doesn't have a removable plug (just a very small hole at the bottom).

So, I just shouldn't worry about mud/sand getting into this thing? It seems like RTV sealant around the clutch cover would prevent most ingress while at the same time the drain hole would allow for breathability during temp changes.

One of the reasons I ask is because the clutch plate recently failed (at the Pismo Sand Dunes no less) and I'm wondering if this might have been the cause...

On Series Rovers the wading plug (a 1/4" pipe plug) is installed before wading, then removed after, to help keep water out. The wading plug came from the factory screwed in to an 'L' shaped bracket attached by one of the bell housing bolts.
Provided you keep it removed during normal operation I can't think of any reason it would be bad to seal the bell housing.
If you do that, it's good practice to do the typical Series "modification" and move the bracket to the dash so there's never any question in your mind if the plug is in the flywheel housing or not.
