Engine Oil Sump Specification Example for Dealership Service: Fixed Type
Engine Oil Sump Specification Example for Dealership Service: Fixed Type
This is a worked specification for engine oil sump in a fixed type 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 fixed type version exists because the duty cycle on dealership service is not the same as on a showroom vehicle. Where the two are specified identically, something fails later — usually warranty claims traced back to a single lot.

Example specification
| Item | Engine Oil Sump |
|---|---|
| Application | Dealership Service |
| Version | Fixed Type |
| Base material | EPDM Rubber |
| Controlled dimensions | 6 key dimensions, recorded per lot |
| Tolerance band | ±0.1 mm |
| Finish | powder coated |
| MOQ | 1,000 pieces per specification |
| Sampling | 14 working days, 5 days per revision |
| Compliance | TUV |
How the example is built up
- Start from the duty cycle, not from the catalogue photograph.
- Fix the base material in writing — EPDM Rubber, 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
- CNC machining
- powder coating
- ultrasonic cleaning
- assembly line testing
- surface grinding
- electroplating
Where this example applies
Programmes that run fixed type most often specify this build for dealership service. Related applications include camper conversions, municipal fleets, three-wheelers, light trucks, passenger cars.
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
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.
Do you handle mixed containers?
Yes. Most programmes consolidate several part numbers into one container to keep freight sensible at 1000 pieces per line.
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 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.
Share a sample or a drawing and we will quote against a written specification, not against a photograph.
