Vehicle Speedometer Tachometer Specification Example for Fleet Maintenance: Budget Line

This is a worked specification for vehicle speedometer tachometer in a budget line 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 budget line 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 reorders that did not match the approved sample.

How the example is built up

  1. Start from the duty cycle, not from the catalogue photograph.
  2. Fix the base material in writing — Polypropylene, 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
  • CNC machining
  • shot blasting

Where this example applies

Programmes that run budget line most often specify this build for fleet maintenance. Related applications include racing teams, city buses, camper conversions, export programmes, long-haul trucks.

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

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 is the minimum order quantity?

The standard MOQ is 3000 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. SAE J431 documentation is issued with the shipment when your market requires it.

Can the specification be held on file?

Yes. Once approved, the specification is recorded against your part number so a reorder reproduces the SAE J431-compliant build instead of a fresh interpretation.

Send the specification you are working to and we will confirm what we can match, what we would change and why.
