Crankshaft Peugeot Wholesale: Buyer Specs and Supply Terms
For buyers sourcing Peugeot crankshaft programmes, the main risk is not the first sample. It is variation across batches, unclear engine-code mapping, and inspection data that does not support incoming quality checks. A wholesale supply decision should be based on dimensional repeatability, material traceability, balancing control, packing quality, and the ability to hold the same specification over time. Driventus is an independent aftermarket manufacturer; brand names are referenced for fitment only. If you are building a replenishment programme, you should verify engine family, journal sizes, runout limits, heat-treatment route, and the documents that ship with each lot. That is the difference between a one-off purchase and a supply line that can support distributors, repair networks, and OEM or Tier-1 sourcing teams.
What wholesale buyers should verify first
A crankshaft purchase is only secure when the source can hold the same geometry, hardness, and balance across repeat orders. For Peugeot applications, buyers usually start with engine code, bearing grade, journal count, and the required counterweight layout. The goal is not a generic listing. It is a part that matches the build specification and can be inspected at receipt without guesswork.
Review our catalog to see the wider engine range, and use the quality system page to check how incoming material, in-process inspection, and final release are controlled. If the part is not covered by a standard programme, custom manufacturing can support drawing review, sample approval, and documentation planning.
For buyers comparing suppliers, the first pass should answer four questions:
- Does the part match the engine code and bearing specification?
- Can the supplier show lot traceability from raw material to packed cartons?
- Are balance, runout, and hardness recorded for each production batch?
- Is the packaging suitable for export, warehousing, and repeated handling?
Key dimensions and inspection points
The most common sourcing failures come from assuming that one crankshaft dimension tells the whole story. Journal diameter, runout, fillet radius, and oil passage alignment all affect fit and service life. Buyers should ask for a measurement pack, not a verbal confirmation.
| Check | Why it matters | Buyer should confirm |
|---|---|---|
| Main and rod journal diameter | Sets bearing clearance and oil film performance | Match the drawing and bearing grade |
| Runout and straightness | Affects vibration and secondary wear | Require recorded measurement on a calibrated fixture |
| Fillet radius and surface finish | Influences fatigue resistance | Confirm process control and inspection result |
| Balance and counterweight mass | Controls NVH and long-term durability | Ask for final balance data |
| Oil holes, chamfers, and threads | Protect lubrication and assembly quality | Verify location, edge finish, and thread form |
| Heat-treatment condition | Impacts wear and crack resistance | Request hardness records and process route |
