In regards to the piston ring set i recieved with my arias pistons.

looking for proper direction of piston ring in the cyl bore.
meaning... upside down, right side up.

heres what i found on hastings site...
http://www.hastingsmfg.com/Ser...n.htm

2nd compression ring:

Some people say dot facing up, other say bevel facing up.

iv spent time on the phone with arias, 2 diff people, 1 has one response, other has a diff respnse.

If hastings is in fact arias ring manufacture, then i belive i answered this question myself already...

What do u guys think ?
is it a general rule of thumb that the "dot" indication should face up ? or bevel face any one direction over the other ?

Top compression ring:

no markings, no bevel ?

so i assume either direction would work... there is no right or wrong way ?

 

i would sooner trust the "bevel" edge of the piston ring for direction over the dot.

there could have been a manufacturing error in regards to the dot but the bevelled edge is always supposed to face the proper direction.

 

Top ring: 1) Bevel up
2) Dot or numbers/letters up
3) Either direction if no bevel or number/letters

Second ring: 1) Bevel down
2) Dot or number/letters up

In twenty five years I have never run into rings that were number/lettered wrong(but your right it could happen)

 

yea i got it guys, thanks.

 

woops, i was on my buddy's computer. anyway.. figured it out.
