Racing Crankshaft Components Specification Example for Export Programmes: All-Weather Version
Racing Crankshaft Components Specification Example for Export Programmes: All-Weather Version
This is a worked specification for racing crankshaft components in a all-weather version programme. It is the document we would send a buyer who asks what exactly they are getting: the material, the dimensions that are actually controlled, the finish, and the checks that happen before anything is packed.
The all-weather version version exists because the duty cycle on export programmes is not the same as on a showroom vehicle. Where the two are specified identically, something fails later — usually inconsistent hardness between lots.

Example specification
| Item | Racing Crankshaft Components |
|---|---|
| Application | Export Programmes |
| Version | All-Weather Version |
| Base material | Anodised Aluminium |
| Controlled dimensions | 5 key dimensions, recorded per lot |
| Tolerance band | ±0.1 mm |
| Finish | as machined |
| MOQ | 2,000 pieces per specification |
| Sampling | 10 working days, 5 days per revision |
| Compliance | RoHS |
How the example is built up
- Start from the duty cycle, not from the catalogue photograph.
- Fix the base material in writing — Anodised Aluminium, in this example.
- List the dimensions that are actually controlled and the tolerance on each.
- Name the finish and what it has to survive.
- State the inspection level and who pays when a lot fails.

Processes involved
- injection moulding
- assembly line testing
- ultrasonic cleaning
- cold forging
- heat treatment
- electroplating
Where this example applies
Programmes that run all-weather version most often specify this build for export programmes. Related applications include aftermarket retail, racing teams, fleet maintenance, trailer axles, emergency vehicles.
Checks before packing
- Dimensional report against the approved drawing.
- AQL 4.0 sampling on the finished lot.
- Finish inspection under agreed lighting.
- Carton drop test on the first lot of a new packing specification.
Questions buyers ask
What happens if a lot fails inspection?
The lot is re-inspected against the golden sample, and replacement pieces ship on the next available booking at our cost.
How long does sampling take?
Samples leave the factory in 10 working days, and each revision round adds about 5 days once you have seen the first piece.
What testing is included?
Standard lots ship with dimensional and hardness reports. RoHS documentation is issued with the shipment when your market requires it.
Can you match an existing sample?
Send a sample and we will reverse-engineer the specification, then produce a counter sample for approval before any bulk starts.
Share a sample or a drawing and we will quote against a written specification, not against a photograph.
