I have found these new style bearings in only two of the trannies that I have rebuilt. The old style input shaft bearing at the intermediate plate has a fragile brass cage for the balls. This new style, of which I have never seen a failure (in the two that I have seen on high milage trannies) has a steel cage for the bearings. I was reacently able to order the new style from GPR so I figured I would take some pics for posterity.
First, the old style bearing cage and its common failure -disintegration. Notice the sharper peaks on the cage when comparred to the new/old style bearings in the next pic. The peaks could be due to wear, but I am not sure. Attached image(s)

These have been available, off and on, for years. They were far cheaper than "the real thing" when they were first available. The reason the numbers are "x"ed out is so you will have a tough time identifying them, or the OE supplier has an exclusivity agreement with Porsche, so they have to "lose' the identification in order to sell them on the aftermarket. $150 is about 10% off of list. I would sell them for that if 10 people wanted one and were willing to pop for them up front. The pinion bearings are the same price. The Cap'n |
