I found another oil ring for my tra12-d and have a question about the scraper ring. It has a profile on it and I'm not sure if it goes up or down, it also has a expander and a steel rail. no info in the instruction as to how to install them. The oil ring is self explanatory and the compression ring has a mark that says top. So if anyone can tell me the way they go on ie. profile direction,steel rail(top or bottom)Thanks.
