RE: Cardin shaft replacement - 2

Thanks, Wessie. I did just return from the garage a minute ago. I looked again with a flashlight and - yes - there is a little rubber flap-like thingy right where it's supposed to be. When I looked before it didn't register that the little protrusion was made of rubber, and could be the plug. All good now.

Looking at the newer parts diagram, I see that there are two duckbill rubber valve thingy's. One is at the swingarm pivot and appears to be at the top of the driveshaft casing and pointing down into the casing. The other is where everyone mentions at the rear bevel drive unit at the bottom and also pointing down to the outside atmosphere. Seems to me that the two valves working together would have some sort of "pumping" effect as the air inside the casing heats up and cools down, or possibly as the rear drive unit pivots, thus expelling moisture. That's my theory anyway.

The rubber gaiters do not provide an airtight seal so l don’t think there’s anything more sinister than gravity at work here.

I looked hard for that 2nd duckbill thing, but if it's there it's well hidden.
