Recently I disassembled, cleaned and greased Nexus 7 hub. After riding I noticed that 1,2 gears not engaging, 3 sometimes works and 7 gear feels more like 5. Not sure what's wrong, I have suspicion about pawls in one part facing in two directions and actually gears on right side from coaster brake are not rotating, here's photo. I used graphite grease, can it's thickness be problem?
