there's a thru hole in the input shaft directly into the innards of the pumpkin. If you pull your final drive and place it with the pinion angled down, the oil will all run out. DAMHIK.
Here's how I found all this - the voyager uses the same setup. they are also known for leaking final drive oil out at the front of the swingarm, by the bevel drive. For years the "fix" was to lower the oil level in the final drives, but that doesn't sound like to good of an idea to me, so when I had one apart I really studied the design, and found the real source of the leak that nobody seemed to know existed. It was because of the pinion oring being broken. On the voyafer, the swingarm is angled down toward the engine, so the oil runs out the swingarm forward.
On connies, the swingarm is more level or angled down towards the final drive. The orings break on connies also, but then the oil usually stays in the back of the swingarm or seeps out and makes a messy bottom on the final drive.
Next time you have a final drive aprt, look way back on the pinion shaft, just ahead of the pinion seal. You'll either see the oring, or the groove it's supposed to be in. there's a corresponding oring sandwitched at the front of the driveshaft spline section, where it's mounted to the driveshaft. Look on the pinion spline area, you'll see the weephole.
This also raises the point that whenever the final drive is removed, the oring on the pinion shaft needs to be inspected. they get pinched and break pretty easily during installation or removal apparently, I've found a few busted already. I posted this all up a couple years ago... Steve
