Racing Crankshaft Components Specification Example for Emergency Vehicles: 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 emergency vehicles is not the same as on a showroom vehicle. Where the two are specified identically, something fails later — usually warranty claims traced back to a single lot.

How the example is built up

  1. Start from the duty cycle, not from the catalogue photograph.
  2. Fix the base material in writing — Kevlar Composite, in this example.
  3. List the dimensions that are actually controlled and the tolerance on each.
  4. Name the finish and what it has to survive.
  5. State the inspection level and who pays when a lot fails.

Processes involved

  • rubber vulcanisation
  • ultrasonic cleaning
  • robot welding
  • CNC machining
  • cold forging
  • anodising

Where this example applies

Programmes that run all-weather version most often specify this build for emergency vehicles. Related applications include fleet maintenance, long-haul trucks, workshop replacements, city buses, courier fleets.

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 testing is included?

Standard lots ship with dimensional and hardness reports. ISO 9001 documentation is issued with the shipment when your market requires it.

Do you handle mixed containers?

Yes. Most programmes consolidate several part numbers into one container to keep freight sensible at 1000 pieces per line.

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 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.

Send the part number, the annual volume and the target market, and we will come back with a specification and a sampling plan.
