Engine Starter System Specification Example for Passenger Cars: Off-Road Version
Engine Starter System Specification Example for Passenger Cars: Off-Road Version
This is a worked specification for engine starter system in a off-road 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 off-road version version exists because the duty cycle on passenger cars 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.
Example specification
| Item | Engine Starter System |
|---|---|
| Application | Passenger Cars |
| Version | Off-Road Version |
| Base material | Neoprene |
| Controlled dimensions | 5 key dimensions, recorded per lot |
| Tolerance band | ±0.2 mm |
| Finish | anodised |
| MOQ | 1,000 pieces per specification |
| Sampling | 10 working days, 3 days per revision |
| Compliance | SGS |
How the example is built up
- Start from the duty cycle, not from the catalogue photograph.
- Fix the base material in writing — Neoprene, 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
- assembly line testing
- rubber vulcanisation
- gravity casting
- ultrasonic cleaning
- surface grinding
- die casting
Where this example applies
Programmes that run off-road version most often specify this build for passenger cars. Related applications include export programmes, racing teams, rental motorcycles, assembly programmes, utility trailers.
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
How long does sampling take?
Samples leave the factory in 10 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. SGS 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.
Do you handle mixed containers?
Yes. Most programmes consolidate several part numbers into one container to keep freight sensible at 1000 pieces per line.
Send the specification you are working to and we will confirm what we can match, what we would change and why.
