What is the function of the oil slinger?How should it be turned? Outer recess In or out?
Why does not main shaft SKF bearing include a seal on the outside? One dollar more in price? Omly seal in front of SKF bering is a felt seal, does it work? |

Sten,
Are you asking about the oil collector and front bearing on the T90? |

I think he may be asking about the front bearing washer (#7 in the service manual diagram)on the input shaft ....
But I can't remember which way it went...sorry....

I am talking about the saucer shaped steel part that is on the main shaft behind the roller bearing. Part nr 61.

Sten,
I'm confused too. I don't see a PN 61 in the transmission listing. Are we looking at two different listings?  |

Is this what you mean? This is the mainshaft or do you mean the main drive gear? Pick a number from the illustration above so we're all on the same page.

That's a T84 shaft, this might confuse matters.

Part #7 is not on the mainshaft, it's on the input gear, and the bearing next to it is not a roller bearing but a ball bearing. And I believe, if you put it against the bearing, not on the shaft, you'll find that if placed one way it will rub on the bearing outer race. It goes the other way. BW

That's why I asked for a number from the illustration. People have a tendency to call something off the top of their head and all it does is confuse the issue.
Not really, it was used to illustrate a mainshaft which I figured might prompt the OP to identify the actual part he was asking about. |

The felt seal was a dead give away in his first post.

Well....no body has answered the orignal questions and I would be keen to know as well...
Sten, the original bearing allows for oil to flow through it and then return via a drilled hole in the front of the casing. So that's why it has no seals. Its very important to refit the nose cone gasket correctly so you don't block off the return oil hole. Re: The felt seal, I have just ordered a new one from Novaks, original has been there 60 plus years and still seems quite intact, but its cheap and it will get replaced anyway... Hope this helps a bit.. Adrian

It's better not to make assumptions though and the assumption there was that whatever shaft it was was being, or had been, assembled correctly to begin with and that the felt seal was being ID'd correctly. |

Adrian, Bruce W answered it. It goes on where the dished in area goes against the inner race of the bearing or like he said it will rub on the outer race.

Thank you Adrian and all others,
Sorry, I used the incorrect word for part nr 8 , I used main shaft , should be main drive gear 640428. I also used the wrong part number 61 for washer ( that was from the previous illustration/drawing of transmission) but same part anyway, 640893. Still confused with the bearing 640781 (SKF 6208) , why does it not have a seal built in on its outside ( front side)? Is the felt seal a good solution? Just trying to avoid making the same mistake twice. Today I got a shipment from Walcks with the 640781 bearing in question and it is not sealed, the shipment also include a felt washer. I do not blame the supplier, they must have a good reason, but my first rebuild failed... oil on my garage floor. Has anyone a success story in this area? Sten |

Sten,
There was no such thing as a sealed bearing back in the 1930's & 40's when these transmissions were built. Lots of folks, including me, have opted to go with a sealed bearing on the front and plug up the return drain hole. There have been several discussions on this. The part number for the sealed bearing is SKF 6208 2RSNRJEM

I just heard back from Novak and they said they can't supply the felt seal, so I too am going to change to a sealed bearing...just pop the inner seal out and let the oil do the job from one side.
Sten, the sealed version of the bearing is available, you just need to ask when you order it, I have an open NSK one now on the shelf and the sealed version in the post. Sorry if I missed the comment on the oil spinner......need to put the glasses back on, still in denial that my eyes are not what they used to be  .Adrian
