I ordered a corvette servo for my car and in teh instructions on sethirdgen.org says to seperatly order a servo housing O ring and the cover O ring. I called auto supermarket, pep boys and advanced and none of them have a listing on it. Is this a dealer only item?

 

gm parts, probuilt, anyone that makes a rebuild kit

 

i ordered a servo from Ebay.

all stuff was there ,including the rings.

Tolm

 

I got some at O'Rileys.

 

If you want the latest "D" sealing rings, I carry these with my Corvette servos.

 

D rings versus O rings ??? WTF..lol. Talk to me ?

 

The D part is the cross section. The stock servo O rings have a square cross section with a scarf cut overlap. The D rings are not cut (solid) with the round portion of the D against the servo bore.

Al.

 

Ok, I understand but is there a need for this new type of seal, some sort of a problem with regular o rings on the servos ?
Basically I am asking why would I want them ? Thx

 

Thay seal much better, than the teflon scarf cut rings, that is why I use them.
