I need three .30mm shims for the end play. The three that I have are .31 and gives me almost 0 end play. I see them at Auto Atlanta but they want almost 20.00 for each of them. Seems like a lot when the type one shims are only 3.00 so if someone has a better source for them please let me know.

Try Retro Automotive in Clairmont, New Hampshire. A huge warehouse full of used Porsche parts.

Mark, Have there been any reports of issues with the shim material hardness like we are now seeing on 616 motors (356/912). Reputable shops (Cranky Jack for one) and DIY folks are seeing some cases where these wear, causing drastic changes in end play in short periods of time, and damaging the engine. Just curious... |

Any chance you could find a single .28mm shim?
Hmm, maybe not. However, AA lists a .24mm shim, but that might be too much endplay. |

I haven't seen or heard anything bad yet. (IMG:style_emoticons/default/confused24.gif) Just wanted to share, since this has been an issue for the 356/912 community. Here are a couple threads from the 912BBS if anyone is curious. http://www.912bbs.org/vb/showthread.php?50...t=shim+hardness http://www.912bbs.org/vb/showthread.php?45...light=blanching I know these are different parts, but probably similar sources and processes. |

How exactly would a shim "wear" ??? (IMG:style_emoticons/default/confused24.gif) There's details in the threads I posted. I am not a SME, just a messenger here sharing information. Could it be soft material compressing over time due to pressure and the ongoing end play shift working on it also? All I know is that folks that do this for a living are spreading caution, so wanted to give a little PSA here. |

The flywheel shims aren't just shims. They are sandwiched between the flywheel (rotating) and the main bearing (stationary). That's the reason three shims are specified. With three shims there should be enough lubrication to minimize friction between the Bearing-Shim-Shim-Shim-Flywheel assembly.
But a certain level of hardness is necessary for the shims. Too soft and even with proper lubrication they can wear away to nothing. Even high mileage original shims show wear. I stopped reusing shims awhile ago just for this reason -- no guarantee they're still flat and consistently thick. |
