Performance Flywheel Specification Example for Workshop Replacements: All-Weather Version

This is a worked specification for performance flywheel 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 workshop replacements is not the same as on a showroom vehicle. Where the two are specified identically, something fails later — usually premature wear on the first batch.

How the example is built up

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

Where this example applies

Programmes that run all-weather version most often specify this build for workshop replacements. Related applications include racing teams, passenger cars, three-wheelers, fleet maintenance, long-haul trucks.

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

Do you handle mixed containers?

Yes. Most programmes consolidate several part numbers into one container to keep freight sensible at 500 pieces per line.

What is the minimum order quantity?

The standard MOQ is 500 pieces per specification. Mixed sizes inside one shipment are accepted once the total reaches that figure.

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 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.

Share a sample or a drawing and we will quote against a written specification, not against a photograph.
