O-rings for thermostat housing

[bernie g]

Does any one know which way the o-rings go for the thermostat housing, they are oval shaped but larger on one side than the other. I would like to know if the larger side goes towards the front or the back or the bike.

Thank you

Bernie G.

I'm not sure what you mean by oval. Does the "O" form an oval or if you cut the o-ring with a knife is the cross-section oval ?

[Ricky-D]

Those O-rings should have a round cross section, that's how they are cast!

If they are deformed it's prolly cause stuff was sitting on top of them while on the shelf.

Get new un's that are correct.

You would hate to use them, only to have them leak down the road!

Ricky.....thats just wrong!  I bought a set of all the 0-Rings needed to reseal the coolant system and the ones that fit the thermostat housing have a "double ridge" profile...like bernie said, they are bigger on one side.  

To answer your question Bernie on which way they go it will be obvious by looking at the ones you take out.  I dont trust micro fish pictures, they get stuff flipped backwards all the time.  I put new 0-Rings in the head pipes of a friends bike and its obvious once youre in there

An 'O'-ring is a torus.

If it is not a torus, then it is something else. But not an 'O'-ring!

Well whatever you want to call it.  Its a ring shaped seal that is like an "O" looking at it square but in cross section it would be "double beaded" or larger on one side than the other.

Its a shame that instead of understanding the question you "trap" the answer in a strict technicality and end up telling someone to send back a part that is probably the perfect part just because EVERYONE calls it an O-ring. 

I think you have some sort of need to be a PITA and also to prove to yourself how smart you are

In geometry, a torus (pl. tori) is a surface of revolution generated by revolving a circle in three dimensional space about an axis coplanar with the circle. In most contexts it is assumed that the axis does not touch the circle (in this case the surface has a ring shape and is called a ring torus or simply torus if the ring shape is implicit). Other types of torus include the horn torus, which is generated when the axis is tangent to the circle, and the spindle torus, which is generated when the axis is a chord of the circle. A degenerate case is when the axis is a diameter of the circle and surface is a sphere. The ring torus bounds a solid known as a toroid. The adjective toroidal can be applied to tori, toroids or, more generally, any ring shape as in toroidal inductors and transformers. Real world examples of (approximately) toroidal objects include doughnuts, inner tubes, many lifebuoys, O-rings and vortex rings.

Please notice the fourth from the last words "O-rings" !!

Well, OK......with that said......Im sure we all know what TO call and what NOT to call an O-ring from now on......degenerate or not.  Ya, think?!

He lost me at geometry!

WOW!!

HE SUNK MY BATTLESHIP!!   lol

Well I'm glad we finally got that strightened out.

Its a FN GASKET

[fat6man]

Bernie... Sorry ya asked????               

[RLD]

So, does anyone have an answer here? Seems like the message got lost.

I put them in the way the microfiche showed (number 16 in Shop Talk), wide end away from the coolant pipes.

[Bone]

Think you meant #19 in Shop Talk. Yes he looked at it again and realized the correct placement of the gasket.

[Jeff K]

I've never paid any attention to it and never had one leak.
I know that's not the answer you were looking for, but that's all I have.
