Racing Crankshaft Components Specification Example for Fleet Maintenance: Reinforced Build

This is a worked specification for racing crankshaft components in a reinforced build 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 reinforced build version exists because the duty cycle on fleet maintenance is not the same as on a showroom vehicle. Where the two are specified identically, something fails later — usually inconsistent hardness between lots.

How the example is built up

  1. Start from the duty cycle, not from the catalogue photograph.
  2. Fix the base material in writing — Aluminium Alloy, 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

  • heat treatment
  • anodising
  • electroplating
  • cold forging
  • shot blasting
  • precision stamping

Where this example applies

Programmes that run reinforced build most often specify this build for fleet maintenance. Related applications include dealership service, camper conversions, emergency vehicles, boat trailers, city buses.

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

How is packing specified?

Individual packing, inner box quantity and carton marking are confirmed at quotation stage so the cartons arrive ready for your warehouse.

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.

How long does sampling take?

Samples leave the factory in 10 working days, and each revision round adds about 3 days once you have seen the first piece.

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.

Tell us the model, the fitment and the quantity and we will hold a production slot for you.
