Engine Assembly Specification Example for Delivery Vans: Load Rated Version

This is a worked specification for engine assembly in a load rated 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 load rated version version exists because the duty cycle on delivery vans 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 — Carbon 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.

Processes involved

  • shot blasting
  • ultrasonic cleaning
  • cold forging
  • injection moulding
  • assembly line testing
  • heat treatment

Where this example applies

Programmes that run load rated version most often specify this build for delivery vans. Related applications include racing teams, boat trailers, dealership service, emergency vehicles, off-road bikes.

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. TUV documentation is issued with the shipment when your market requires it.

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.

Can the specification be held on file?

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

What is the minimum order quantity?

The standard MOQ is 2000 pieces per specification. Mixed sizes inside one shipment are accepted once the total reaches that figure.

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