Default Quick question! That plastic winged thing on the input shaft...

So while replacing my clutch slave, I somehow managed to lose the winged plastic X that screws into the back of the input shaft. Is it required to prevent the shaft from coming out of the pilot bearing during shifting? And could I just replace it with a nylon bolt of similar thickness?

From what I hear, that propeller is supposed to circulate oil around the pilot bearing, so I'd say it's important. From what Bentley says, the bearing could seize without that little plastic piece being in. Perhaps you could fashion one yourself?

Ah, in a moment like this, wouldn't it be a handy time to own one of those 3D printers that can make anything out of plastic?

Ah damn, I didn't even think of that.

I'll go pull one off a salvage car, I was just hoping to avoid the drive to Stockton because no one seems to have a saab locally.

Thanks.

The X that screws into the input shaft. I believe that is stop oil coming out the breather hole in the input shaft cover on the primary case. But you're right Bentley does say it's for the bearing. Not sure how it would lube the upper sprocket bearing.

I don't think it assists in lubricating the upper sprocket bearing but nutcase or peva would know.

As I understand it, it flings oil around, fmainly away from the breather hole. Some may end up on the upper sprocket bearing but I'd suspect not much.

I tend to agree with Nutcase. I know it says it helps to lubricate the bearing but I can't see it, but I reckon it keeps the majority of the oil away from the breather hole. I have a theory that sometimes statements are made in manuals because the manual author has to say something and not admit his ignorance. Mind you that's only a theory, but it won't be the only thing the Bentley is wrong on. . I have seen a few 900 transmissions without this flinger and they haven't failed. The EPC doesn't help either. It just calls it a screw.

Well, I got concerned enough to start digging through the trash, figuring my girlfriend probably swept it up and threw it away (something i would not have done if it was replaceable by a nylon bolt) and actually managed to find it. I suppose the peace of mind makes it worth it. Or at least, that's what I'll tell myself

And I'm one step closer to making this car an actual practical vehicle!

It's an oil slinger, it has nothing to do with lubricating any bearing. They do leak out of the breather without it.
