Why this part
Running a generic washer or nothing at all concentrates clamping force on a small contact patch — enough to distort an insert bore or encourage movement over time. The Dart washer is dimensioned for the casting geometry it sits against. At $14.35, it costs less than the labour to pull the head back off.
