Set identification
Rotor/stator side, segment quantity, layout, rotation or refining direction.
Measurements should reconstruct the mounting and set definition. Worn surfaces require engineering judgment before they are treated as original geometry.
Rotor/stator side, segment quantity, layout, rotation or refining direction.
OD, ID, radial length, thickness and relevant seating surfaces.
Bolt circle, hole quantity/diameter, countersink/counterbore and locating features.
Bar/groove direction and measurable unworn reference areas where legally usable.
A worn sample can preserve mounting geometry while losing the original bar height, groove depth or edge condition. Reconstructed pattern geometry should be explicitly reviewed and approved.
Mark rotor/stator side, segment position and direction.
Establish repeatable mounting and seating datums.
Capture critical fit dimensions separately from worn refining features.
Compare sample measurements with any lawful drawing or historical record.
Freeze a buyer-approved manufacturing definition before tooling or production.
Indicate whether dimensions, a sample or a controlled drawing are available for later private review.
