How to install a pilot bearing correctly
I have an NOS pilot bearing that has an open side with the ball bearings exposed. The other side is sealed. Which side goes into the crank? I'm thinking the bearings should show so that it can be greased at every clutch replacement. Or does it even matter? Must be a reason GM left one side open other than saving a few cents.

Seal out and put some grease in the hole.
Seal in would get clogged up and dried out with clutch dust in no time at all. Clay |

Sealed side goes OUT, towards the transmission
And then you can put a little hi-temp grease in the crank recess behind the bearing. It will migrate into the bearing as needed.
That's what Pontiac did originally. Not sure if it is in the service manual or not. The properly-lubed bearing will last indefinitely. Good luck! |

Not so much that the input shaft hydraulics and won't go in all the way.

Install the bearing FIRST, then jab some grease thru the hole into the recess.
Like hobbygto65 says, don't put so much grease in there that the bearing gets pushed out.
We normally put the bearing in, stake it lightly and then stick two or three globs of high-temp grease thru the hole before we install the transmission. The grease will move to where it needs to be when the engine is running. |

What these gents said about the open end facing the crank and getting good quality high temp grease. I installed mine in 1984 and all is still good. If I ever have to replace the clutch, the bearing will get replaced as well.
