Idler Pulley for A fleet operator in North America
A fleet operator came to us with a idler pulley programme for North America. 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
- Packing that arrived crushed at the port
- A supplier who changed material without saying so
- A fitment that looked right on paper and failed on the bench

What was specified
| Part | Idler Pulley |
|---|---|
| Client | A fleet operator |
| Market | North America |
| Volume | 5,000 pieces across 4 specifications |
| Base material | Reinforced Nylon |
| Sampling rounds | 2 |
| Delivery window | 5 weeks from PO to ex-factory |
| Compliance | SGS |
How it was resolved
- The specification was rebuilt around Reinforced Nylon 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 5-week window.
- Unit cost held within 3.0% 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
Keep one accountable owner on both sides. Most delays come from hand-offs, not from machines.
