Can the pilot bearing be installed into the flywheel without a press. I do have a vise. Any good easy methods?

I just tapped it in with a hammer on everyone I have done. It doesnt take much so dont pound on it like you are driving a nail. Just tap it in.

In fact, I think I used a 1/2in deep socket on it. Works great. (IMG:style_emoticons/default/smash.gif)

Thanks Scott, that was my plan but I read or heard somewhere about using a press.

Just use a nut and bolt with some washers. Good as a press easy to keep it straight. Then graduate to a socket to get it recessed for the felt seal.

QUOTE Then graduate to a socket to get it recessed for the felt seal. When I took this fflywheel off there was no felt washer and the bearing was flush in the flywheel. If I recess it on the engine side of the flywheel, it will stick out on the other side of the flywheel. (IMG:style_emoticons/default/confused24.gif) |

From the factory manuals. 3.2 mm depth on the friction side.

Maybe someone that knows for sure will answer, but as I recall, the felt went on after the pilot bearing is tapped in - which puts it on the outside of the engine.

The pilot bearing goes in the flywheel, not in the crank.
The felt washer goes on the friction surface side of the flywheel, underneath the six hole "washer" plate. |

I used a block o' wood to tap it flush - then a socket to tap it in. Checked depth with a dail micrometer and tapped until it was there.

914 Wizard? No way. I got too much to learn. Group: Members Posts: 4,099 Joined: 21-April 03 From: Gig Harbor, WA Member No.: 598 |
The pilot bearing does sit in the flywheel. It should be 3.2mm recessed to leave space for the felt washer. There is a spacer in the end of the crankshaft that prevents the pilot bearing from being installed to deeply.
Miy spacer was missing in the new crank and the only one I could find new was from Porsche in a warehouse in Germany. I finally made one from some pipe I had around. I don't recall the dimensions. It just took some measuring and fitting. If I remember it was a pilot bearing installed in the crank instead of the flywheel that ate SirAndy's input shaft seal. Dave |

I said six holes because there's one in the center. (IMG:style_emoticons/default/ohmy.gif)

Because I was talking about the six hole "washer" plate that doesn't have a hole for the alignment dowel. (IMG:style_emoticons/default/rolleyes.gif)
Sheesh! (IMG:style_emoticons/default/lol2.gif) |
