A reputable engine builder in my area recently told me that the "Made in Germany" Glycos are ok.
Is there any basis to this? Are the 3.2 glycos made elsewhere now? |
|
Sorry for the slight off-topic, I wish to ask a question about main bearings (as opposed to rod bearings). Why was the part number for the main bearing shells changed in 1976 for all models (911, 911S, 911/83, Carrera 3.0 and Turbo 3.0) if the they remained the same size?
|
The nose of the bearing is on the other side...
|
Did you mean notch?
|
Yes notch, sorry
|
I wonder if this has anything to do with the fact that the Vertex advertising now includes text that says "Glycos, Made in Germany"? Or I could be a little too much of a conspiracy theorist...
|
MaRu,
Thank you so much. |
I have a new set of 2.4 Glyco's rod bearings. The box reads "made in Poland"
|
This is where you can check for markings to make sure they are authentic.

I am a Porsche tech and i just checked our parts catalog. The part number for 3.0 engine crank bearings and GT3 crank bearings are the SAME. When you go to the bearings for a 3.0 engine it supercedes to the 996 GT3 bearing part number 96410190100. List price is $840!! I also don't know what to do as i am afraid of using the glyco ones in my 3.0..

Well don't pay $840 for them. Discounted dealers have them for ~$660. That part number includes the #8 main bearing insert. You can typically reuse the old #8 bearing so you may want to consider re-selling the new #8 that is included with 96410190100 for around $200.

Bump -- anyone know the part number/source? I'm looking for them as well. Seems rather pricey at ~$450/set. What bearings are they mating these up as? thanks, Mike |
Ask Pelican if they can share some more specifics on the Clevite 77 bearings. They now show them in their catalog for 2.7L and lower engines

Just purchased a set of Clevite rod bearings. They are a "HX" series bearing developed for NASCAR racing with a dry film lube. Check out the Clevite web site for a detailed description. They fit the rod perfectly.

What's the part number?

I do find it ironic that the mahle/clevite pdf has vehicles(probably tractors) I've never head of, yet do not list Porsches. They also have Yugos -- who the hecks rebuilding those :-) Mike |
I emailed Steve a few weeks ago, and he said he had his replacement bearings in stock. They supposedly require a new notch cut in the rod. I asked about price but didn't hear back.
I'm proceeding with Glycos, since mine were made in Germany in Feb. 2010. |
