Steel Piston Pin Specification Example for Camper Conversions: Quick Fit Version
Steel Piston Pin Specification Example for Camper Conversions: Quick Fit Version
This is a worked specification for steel piston pin 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 camper conversions is not the same as on a showroom vehicle. Where the two are specified identically, something fails later — usually lead time that slipped twice before bulk started.

How the example is built up
- Start from the duty cycle, not from the catalogue photograph.
- Fix the base material in writing — Aluminium Alloy, 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
- sintering
- shot blasting
- precision stamping
- laser cutting
- heat treatment
- injection moulding
Where this example applies
Programmes that run quick fit version most often specify this build for camper conversions. Related applications include city buses, construction equipment, off-road bikes, three-wheelers, assembly programmes.
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 500 pieces per specification. Mixed sizes inside one shipment are accepted once the total reaches that figure.
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.
Send the specification you are working to and we will confirm what we can match, what we would change and why.
