wrist pin snap rings

when installing wrist pin snap rings does it really matter where the open end faces? Are the snap rings as good as the spiral rings? I always face the opening up or down but if it faces sideways will they come out?

Some people claim they can and do sometimes chafe the groove badly.
Personally, I have never seen them come out in any orientation; and that includes motorcycles and snowmobiles.

The guy that did my machine work looked at me like I was stupid when I asked him about using spirolox instead of the snap rings,"why would you want to do that he said". As far as positioning he said one up,one down and the square side of the clip to the outside(rounded sides should be touching each other).

As far as positioning as mudtrucker said the sqaure side should be againt the outside of the part it is holding and the rounded side againt the part the square part is to help it hold in the groove as the part sometimes try to push the clip out, as the rounded part against the part help when stalling them. Some times it is hard to tell the square side from the rounded side I take the ring and pull it across my pom to find the the square side as it will drag aliitle more than the rounded side.

im gonna have to remove a c clip, i didnt see a flat side when i put them in. they came with my MAHLE pistons

I've seen both snap rings ans spiral locks come out.

In their defense, they were never in there right to begin with...

Germans do strange things..which, oddly enough, is the same thing they say about us.
