Racing Crankshaft Components Specification Example for Assembly Programmes: Touring Version
Racing Crankshaft Components Specification Example for Assembly Programmes: Touring Version
This is a worked specification for racing crankshaft components in a touring 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 touring version version exists because the duty cycle on assembly programmes is not the same as on a showroom vehicle. Where the two are specified identically, something fails later — usually a specification nobody had written down.

How the example is built up
- Start from the duty cycle, not from the catalogue photograph.
- Fix the base material in writing — Nylon 66, 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
- surface grinding
- injection moulding
- ultrasonic cleaning
- robot welding
- gravity casting
- sintering
Where this example applies
Programmes that run touring version most often specify this build for assembly programmes. Related applications include construction equipment, delivery vans, export programmes, dealership service, city buses.
Checks before packing
- Dimensional report against the approved drawing.
- AQL 2.5 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.
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.
What is the minimum order quantity?
The standard MOQ is 1000 pieces per specification. Mixed sizes inside one shipment are accepted once the total reaches that figure.
What testing is included?
Standard lots ship with dimensional and hardness reports. TUV documentation is issued with the shipment when your market requires it.
