I am putting a Sifton oil pump on a 1983 FLT. When I took it out of the box, the gears fell out of it. I'm not sure which way they face in the pump. They each have a mark on them. A dot indented. I thought when I first looked at it, one was facing each way, but I'm not sure. I was hoping someone from this forum would know. Thanks in advance for any information.
