Hello,

I have a new Alpha Gen 1 and I discovered that one of the tabs is broken off of the main retainer nut at the input shaft. It appears that in shipping the u-joint yoke was not well supported and the yoke was pressed hard against a couple of the tabs and one broke off.

For one, it seems that the yoke shouldn't be able to break one of these off just in normal handling of the drive.

For two, can the drive still be used with an understanding that the tab that broke off does not encroach into the threads or sealing surface in any way.

I'll get pictures in a little but, but I would like any feedback I can get.

I see no problem running the drive with a broken tab... What I can't see is how the yoke was bent that far back. I would be inspecting that yoke VERY carefully...

Thanks for the response.

I was thinking the same thing on the yoke. I was really surprised that this was broken.

I attached some pictures. Any feedback would be greatly appreciated.

File a claim. That aint right. That drive is too expensive to receive damaged (even if it is "cosmetic" as it is here)

Yes, it will cause problems.

The large quad ring in the bellhousing will not seal there. When the drive is tightened, the gasket squeezes out of place and allows water into the bellows. Seen it happen a couple of times.

Believe me, I'll be filing a claim. I'm just wanting to know the consensus on how/why the tab was broken and whether or not the drive is useable.

We are already losing time on our very short boating season here. Very frustrated.

Thank you Don for the response.

That seal ring in the bell housing was my first concern. Your right, it won't work.

I suppose a little shorter season is better than rusted u-joints or sunk boat.
