Our FR5 puck pickup now leans toward the fixed finger, another pickup edit made it look better for a while but the same lean returns; I have stopped the edits because nobody can explain why the old position stopped working.
Use the same identified puck for a few comparisons before buying parts. Or rather, keep both the puck and its tray pocket identified; changing both makes a very cheap test surprisingly expensive to interpret.
We chased a similar lean through the tray once. Worn contact on one finger, in our case. A photograph straight down made the part look seated because you couldn't see the little lift at the back.
The clips show three pockets and the lean is toward the fixed finger in all three; maintenance also found a loose pad screw during inspection, pad and contact face now being checked.
That still gives maintenance a useful direction to investigate. The edited setup will need reviewing with the pad repair, otherwise the adjustment made around the loose pad stays in the comparison.
