Most of the visitors to this website can identify this gasket.
At the 4 o'clock position you can see 2 smaller holes on either side of the stud hole.

1) What are these holes for?

2) What position do they go when installing?

Guys like Newk or other transaxle builders are asked to refrain from answering.

IIRC, those small holes indicate the gasket thickness. The gasket pictured should be a .2mm. As far as the position they're supposed to go, I have no clue but I'd guess you don't want them lined up with the holes in the preceding gasket.

Did I win? ;)

Still looking for an answer to this brain teaser. Who knows?, my information may be wrong. Wouldn't be the first time. If this one goes beyond the BOR weekend, I will post my "adopted" answer.

More will follow, and it will get more fun!

OK.....it's past BOR 62. This site has officially gone public and we still don't have an answer to the question about the axle tube gasket.
OK Trans builders now is your chance to share your knowledge with this audience.
If no one has the same answer as me, I will post what I believe to be the correct answer tomorrow.

I allways put the two smaller holes striaght up don't know why i just allways have. I also have never seen any other size as ETR states with differant holes i think they all have the 2 holes.

So far so good Jerry! Now......do you stagger them or do they always go in the same position?

ETR is correct, they indicate thickness. It's in the purple Haynes VW beetle & ghia 54'-79' manual, 1 hole is .004-inch and 2 holes are .008-inch. As far as position, I don't think it matters but positioning the holes up top would be my personal choice.

I have allways lined them up maybe they work as a vent or breather.
That is what I learned years ago. The smaller holes work like a breather for the axle boot. Holes go up and they are lined up.
I have never seen one of these gaskets with a single hole but there is 2 part numbers that indicate thickness: 111-501-131 and 111-501-133.
I have ordered both part numbers over the years and they have the same 2 holes. Maybe something has changed over the decades. Some parts houses have dropped the second number and use 111-501-131 exclusively. I have found whatever thickness they send you, is what they have in stock, just the luck of the draw.
Maybe Rick Sadler or one of our other industry leaders can shed a little more light on this.

I don't have a purple Haynes Manual, but I'm pretty impressed that they would identify a gasket to that extreme. None of my shop manuals make any reference to the gasket thickness. Thanks for the resource Lanky.

This particular brain teaser was a great exercise. Hope others learned something, I certainly did.
Remember....you saw it here on UltimateAirCooled.com

I guess we have a 3 way tie
