Power train manufacturing data for AI build and ratio records
The Census category covers vehicle transmission and power train parts.
NAICS 336350 · Motor Vehicle Transmission and Power Train Parts Manufacturing
The Census category covers vehicle transmission and power train parts. An original task can preserve the distinction between the ratio described in a design register and the configuration recorded for an assembled gearset. Census power-train scope
Create fictional gearset identifiers, an issued component list and a completed build record. State an original exercise rule for relating component identifiers to a ratio label. Ask which label is supported for the selected build. Include a planned component substitution and a report for a different gearset with the same housing reference. The key should follow executed components.
Annotate assembly, component set, ratio label, rule version, build event and document status. Reserve a new component naming scheme for evaluation. Score planned parts treated as used, common housing mistaken for identical internals and an old mapping rule applied independently. Supply a complete case whose ratio label can be reproduced from its cited inputs.
Use invented documents without production geometry, operating parameters or mechanical testing. Customer designs, licensed transmission software, supplier terms and outside reports require appropriate authority. Describe the configuration-to-label task and specialist-reviewed key in the licensing brief. Confirm buyer scope before preparing historical records or new capture. No actual fitment or power train performance determination follows from the exercise.

Original Fiund exercise
A planned ratio and an observed ratio must keep their basis
Invented gearset cards use symbolic configuration and toy turn counts. There is no real powertrain design or setup.
| Record | Source | What it records |
|---|---|---|
| 1 | Issued list | Build U5 planned gearset A; record ratio as input turns per output turn. |
| 2 | Completed record | U5 logged with gearset B. |
| 3 | Toy observation | U5 input 15 turns and output 5 turns in the same interval. |
Question for the model
What can the record say about the completed ratio and variant?
Show the reference answer and checks
U5 has a recorded gearset B, differing from the issued A. The paired counts in record 3 give 3 input turns per output turn under record 1's convention. Keep the measured ratio with the completed build; do not use it to infer A's behavior.
- Attaching the observed ratio to the planned gearset
- Reporting the reciprocal without naming its basis
Fields to preserve
- issued_gearset
- Represents plan
- completed_gearset
- Identifies the observed build context
- ratio_basis
- Preserves input and output roles
Test another case
Provide a measurement captured before a documented replacement; associate it with the gearset installed at the time.
No actual gear designs, ratios for real vehicles, service instructions or performance claims.

Describe the sources you control, the task they could support and what has already been checked. Use the existing-data assessment for an archive or the collection brief for a new recording project. The contributor agreement defines Fiund’s licensing authority and compensation. A guide or fictional exercise does not establish an accepted collection or a sale.
