I'll be honest with you, I don't see issues like this after pump builds. All the parts are reworked and inspected/measured. The pumps are built like a mathematical formula, always the same. Formula's are always the same, unless changed. Once we have the same formula, and measured values within specification, the end result is always the same. Only if the formula is changed or a measured value out of spec. is the end result different.
2+2=4, Always.
