Adapter mismatch before the tool is even fitted

Arm identifier matches. Adapter item label doesn't. The suffix is only on the seller's sticker. I've corrected the request so it focuses on the supplied adapter.

That should be easier for them to answer. Have they sent a drawing for the delivered adapter?

No drawing. Just a photo with 'same function' written underneath. We already have a fairly good view of the thing sitting here.

Which locating feature differs? A measured comparison against the approved drawing would let you ask about the actual interface rather than the photograph's appearance.

The shoulder that locates our tool plate. Toolroom is checking its dimensions against the drawing. We haven't modified or fitted either part.

Good. Don't make it fit while they're still answering.

Who owns the decision if they offer another adapter? I'd have the tooling designer involved before purchasing accepts a substitute and hands you a new drawing to make work.

Our stores descriptions once made two different inserts look interchangeable on the pick list; I'd ask them to confirm the actual adapter identifier in any replacement offer, not just 'correct part'.

Tooling designer reviews it with purchasing. Stores has the disputed item tagged separately. No more generic adapter description in the case notes.

Toolroom confirmed the shoulder differs from the approved drawing. Seller now offers to send the agreed adapter. We have asked them to identify it before dispatch.

Did the comparison include the resulting tool position, or only whether it bolts together? Both matter if anyone is still proposing to use the supplied adapter.

Both checked. Tooling rejected using the supplied item with our setup. We're pursuing the agreed replacement, not adapting this one.

Understood. That answers my concern.

Any actual replacement dispatch yet?

Not yet. We have the proposed replacement identifier and tooling is checking the supplied drawing. The bench stays waiting until the right item arrives and is checked.

Leave that last receiving check assigned to someone. After a long email exchange, a parcel arriving can feel like the finish even when its contents still need matching to the agreement.
