Engine Oil Sump Specification Example for Light Trucks: Racing Spec

This is a worked specification for engine oil sump in a racing spec 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 racing spec version exists because the duty cycle on light trucks 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 — Bronze, 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

  • sintering
  • surface grinding
  • anodising
  • die casting
  • heat treatment
  • precision stamping

Where this example applies

Programmes that run racing spec most often specify this build for light trucks. Related applications include emergency vehicles, scooter fleets, city buses, aftermarket retail, agricultural trailers.

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

Do you handle mixed containers?

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

What testing is included?

Standard lots ship with dimensional and hardness reports. SGS 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 SGS-compliant build instead of a fresh interpretation.

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.
