Here's one reference. As I mentioned, if the ring is reversed it will not match the groove and will not meet its minimum engage measurement which was also missed during the assembly. The fact they are using Go-No Go gages to check that engagement measurement shows this point.

Perhaps they need to hire someone with drafting experience.
Keep in mind these are not engineering diagrams but maintenance work aids. The written note to orientate the ring takes precedent. If you look hard enough you'll find this issue to be a "feature" of many maintenance diagrams.
