Engine Oil Sump Specification Example for Export Programmes: Quick Fit Version
Engine Oil Sump Specification Example for Export Programmes: Quick Fit Version
This is a worked specification for engine oil sump in a quick fit 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 quick fit version version exists because the duty cycle on export programmes is not the same as on a showroom vehicle. Where the two are specified identically, something fails later — usually inconsistent hardness between lots.

Example specification
| Item | Engine Oil Sump |
|---|---|
| Application | Export Programmes |
| Version | Quick Fit Version |
| Base material | Carbon Fibre Composite |
| Controlled dimensions | 6 key dimensions, recorded per lot |

| Sampling | 14 working days, 5 days per revision |
| Compliance | SAE J431 |
How the example is built up
- Start from the duty cycle, not from the catalogue photograph.
- Fix the base material in writing — Carbon Fibre Composite, in this example.
- List the dimensions that are actually controlled and the tolerance on each.
- Name the finish and what it has to survive.
- State the inspection level and who pays when a lot fails.

Processes involved
- injection moulding
- cold forging
- robot welding
- shot blasting
- powder coating
- sintering
Where this example applies
Programmes that run quick fit version most often specify this build for export programmes. Related applications include emergency vehicles, long-haul trucks, boat trailers, fleet maintenance, rental motorcycles.
Checks before packing
- Dimensional report against the approved drawing.
- AQL 1.5 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 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.
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 is the minimum order quantity?
The standard MOQ is 1000 pieces per specification. Mixed sizes inside one shipment are accepted once the total reaches that figure.
How long does sampling take?
Samples leave the factory in 14 working days, and each revision round adds about 5 days once you have seen the first piece.
Share a sample or a drawing and we will quote against a written specification, not against a photograph.
