Air Auto Filter Specification Example for Rental Motorcycles: Standard Replacement
Air Auto Filter Specification Example for Rental Motorcycles: Standard Replacement
This is a worked specification for air auto filter in a standard replacement 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 standard replacement version exists because the duty cycle on rental motorcycles 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 | Air Auto Filter |
|---|---|
| Application | Rental Motorcycles |
| Version | Standard Replacement |
| Base material | Tempered Glass |
| Controlled dimensions | 4 key dimensions, recorded per lot |
| Tolerance band | ±0.2 mm |
| Finish | as machined |
| MOQ | 3,000 pieces per specification |
| Sampling | 14 working days, 3 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 — Tempered Glass, 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
- anodising
- shot blasting
- assembly line testing
- robot welding
- die casting
- CNC machining
Where this example applies
Programmes that run standard replacement most often specify this build for rental motorcycles. Related applications include trailer axles, camper conversions, assembly programmes, municipal fleets, 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
Can the specification be held on file?
Yes. Once approved, the specification is recorded against your part number so a reorder reproduces the SAE J431-compliant build instead of a fresh interpretation.
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 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 3000 pieces per line.
Send the specification you are working to and we will confirm what we can match, what we would change and why.
