'92-96 Dash Register ( (F2TZ19893C, F3TZ19893H)) Repair
IF THE IMAGE IS TOO SMALL, click it.
1) This is a common problem with these registers - someone jams a finger between the 3rd fin & another, and the peg shears off leaving the master fin independent of the slave fins (which still move together). Normally, I salvage a master fin from another register with different damage, but I wanted to see how hard it is to repair one.
2) By gently bending the fin and pushing to one side, its pivot peg can be removed from the hole on the other side.
3) If necessary, extract the remains of the sheared peg.
4) I found that a 1/16" drill bit is too large, but I found this smaller carbide burr to be a good fit. I eyeballed it to make a ~1/8" deep hole in the damaged fin.
5) This soft wire is about the same size, so I bent it to make a handle with enough length to protect my fingers as I heated it with a torch & then inserted it in the plastic.
6) After it cooled, I cut the wire off flush with the fin's edge.
7) I inserted the repaired end into the 2 holes first, then set the vertical fins & slide to match each other, bent the master fin, and re-inserted its other pivot.
It's working smoothly so far.
