Trans Bearings

[joes]

Where can I get some reasonably priced bearings, more than $130 per is too much for a bearing worth about $20. Anyone have different numbers or anything?

I took an intermediate bearing to a bearing place once - they said they were not able to cross it and it was a specialty bearing only available through the automotive channels.

me too. Same story. I did find a bearing which would fit, but it does not have the lip to hold it to the intermediate plate. It was $25

Here's a paragraph from the February 2003 issue of GRM where they rebuilt the tranny from their 1973 project 914:

Once you get it apart, you can begin to look your transmission over for damage. The first problem most of these gear boxes will have is wear on the dog teeth (or what Porsche refers to as the synchro hub), which are pressed onto the gears. Naturally, first and second experience the most problems. At the same time you will want to look your synchros over carefully. What you are looking for is shiny areas on parts that contact each other. Shiny means wear, and wear is bad.
Generally, the most common synchro problems occur with second gear. Although our gear box was in pretty good shape, with only first and second gears needing attention, we still needed about $600 worth of parts. Normally the bearings stay good except for the intermediate plate bearings, which cost roughly $300 to replace. Ours were fine.

Elsewhere in the article they mention that it takes about six hours to rebuild the tranny for about $300 in labor. Is this cost typical? $900 is a lot of money but it's much better than the $3000 figure that I've seen thrown around ...

The double row bearing in the intermediate plate is not a $20 bearing. You will instantly know that by looking at the new one you should purchase. The brass cage is the usual wear item and will fall out in pieces. If not now, it will soon. So, if you are in there that far, do yourself a favor and replace it with a brand new part.

As far as cost, once you price all the parts that you will need for a PROPER rebuild, $1500~2000 for parts and labor is more like it. For example, just replacing the dogteeth and the synchro and not the slider ($$$) is a gamble. I reused the 1st gear slider and I am regretting it on every shift into the 1st gear. That is a lot of sorrow for a daily driver.

Good luck.

If you are replacing 1st/2nd gear syncros, first/second gear dog teeth and slider the money starts to add up.
A tranny that has run dry will need the bearings replaced,
About to the $900 in parts already.

[red-beard]

The "worst case" is $2400 in parts and $500 in labor, which replaces every normal internal wear parts.

I've heard that Porsche has crate trannies back in the Fatherland. I wonder what a NOS tranny would cost...

You are going to LYAO James.

As of 1991, a crate 914 transaxle was $16,800 from a Porsche dealer in Ft. Lauderdale.

AFJuvat said they are listed for MUCH less, but that was my quote.
