Clutch Master Cylinder for A courier company in Oceania
A courier company came to us with a clutch master cylinder programme for Oceania. The brief was ordinary and unforgiving at the same time: a fixed launch window, a landed cost that had to survive freight and duty, and a part that had to match an existing sample. This case records what was specified, what went wrong in sampling and how the bulk order landed.
The starting point
- A specification nobody had written down
- Warranty claims traced back to a single lot
- A supplier who changed material without saying so
What was specified
| Part | Clutch Master Cylinder |
|---|---|
| Client | A courier company |
| Market | Oceania |
| Volume | 5,000 pieces across 4 specifications |
| Base material | Anodised Aluminium |
| Sampling rounds | 4 |
| Delivery window | 8 weeks from PO to ex-factory |
| Compliance | ISO 9001 |
How it was resolved
- The specification was rebuilt around Anodised Aluminium and the tolerance locked before bulk.
- A pre-production sample was approved and kept as the golden reference.
- Production ran with in-line inspection and a mid-run photo report.
- Cartons were packed to the client's own barcode and ratio specification.
- Documentation shipped with the goods instead of after them.
Result
- 5,000 pieces delivered inside the 8-week window.
- Unit cost held within 2.0% of the original quotation.
- Inspection-related rejection stayed under 1.0%.
- The specification is on file, so reorders reproduce the approved sample.
What we would repeat
Fix the specification count early. Adding variants after production starts is the most expensive change a client can request.
