Calculation method
Calculation method
Candidates whose entire predicted interval lies in target, by valve
Use predicted clearance=measured+installed shim−candidate, and require predicted±uncertainty inside supplied target.
Candidates whose nominal predicted clearance lies in target
Apply the same direct-shim model at nominal measured clearance only.
Current nominal measured clearance inside supplied target
Compare nominal current measurement to supplied inclusive target interval.
Continuous candidate-thickness interval satisfying uncertainty bounds (mm)
[measured+uncertainty+installed−target max, measured−uncertainty+installed−target min]; report Empty if reversed.

Assumptions & limits
Assumptions & limits
- Arithmetic for an explicitly supplied direct shim-to-clearance minus-one relationship, not a universal valve-train model or installation instruction. Shim compatibility, target, uncertainty, mechanism and final physical verification are external; no part is selected or ordered.
