Inline Engine Specification Example for Light Trucks: Drilled and Slotted
Inline Engine Specification Example for Light Trucks: Drilled and Slotted
This is a worked specification for inline engine in a drilled and slotted 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 drilled and slotted 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 a fitment that looked right on paper and failed on the bench.
Example specification
| Item | Inline Engine |
|---|---|
| Application | Light Trucks |
| Version | Drilled and Slotted |
| Base material | Anodised Aluminium |
| Controlled dimensions | 4 key dimensions, recorded per lot |

How the example is built up
- Start from the duty cycle, not from the catalogue photograph.
- Fix the base material in writing — Anodised Aluminium, 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
- gravity casting
- CNC machining
- electroplating
- robot welding
- assembly line testing
- powder coating
Where this example applies
Programmes that run drilled and slotted most often specify this build for light trucks. Related applications include city buses, courier fleets, utility trailers, emergency vehicles, assembly programmes.
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 7 working days, and each revision round adds about 3 days once you have seen the first piece.
What testing is included?
Standard lots ship with dimensional and hardness reports. E-mark documentation is issued with the shipment when your market requires it.
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.
What is the minimum order quantity?
The standard MOQ is 200 pieces per specification. Mixed sizes inside one shipment are accepted once the total reaches that figure.
