BMW N55 Valvetronic Eccentric Shaft Kit 11377589883
The BMW N55 Valvetronic eccentric shaft kit is a defined aftermarket supply package built around the 11377589883 eccentric shaft. It is intended for distributors, engine rebuilders and procurement teams that require the shaft, actuator and support bearings under one approved product code.
Each kit contains 1 eccentric shaft, 1 actuator motor and 6 needle bearings. The configuration provides a clear purchasing boundary for buyers who need a complete Valvetronic III eccentric-shaft assembly rather than a shaft-only order.
The related OE references are 11377589883, 11377603979, 11377599021, 11377615379, 11377500978 and 11370150710. Final application approval should be based on the original component number, N55 engine version, vehicle production information and the agreed kit contents.
The minimum order quantity is 5 kits. Neutral packing and buyer-specified labelling can be discussed for wholesale and private-label programmes.
BMW N55 Valvetronic III Eccentric Shaft Kit
This BMW N55 Valvetronic eccentric shaft kit is designed for professional buyers sourcing a defined shaft, actuator and support-bearing assembly under one product reference.
The page serves complete-kit procurement intent. Buyers who require only the shaft should refer to the BMW 11377589883 eccentric shaft product page.
Confirmed N55 Kit Specification
| Product | BMW N55 Valvetronic Eccentric Shaft Kit |
|---|---|
| System Type | Valvetronic III eccentric-shaft assembly with actuator and support bearings |
| Engine Platform | BMW N55 |
| Kit Contents | 1 × Eccentric Shaft, 1 × Actuator Motor, 6 × Needle Bearings |
| Minimum Order Quantity | 5 Kits |
Component Identification and OE References
| Component | OE Reference | Identification Note |
|---|---|---|
| N55 eccentric shaft | 11377589883 | Primary shaft reference and the main identifier for this product set. |
| Valvetronic actuator motor | 11377603979 / 11377599021 | Separate actuator references that must not be confused with the shaft number. |
| Needle bearings | 11377615379 / 11377500978 / 11370150710 | Support-bearing references supplied as six bearings within the confirmed kit. |
The 11377589883 number identifies the eccentric shaft. It is not the actuator-motor number. Keeping these references separate helps distributors reduce catalogue ambiguity, quotation errors and incorrect warehouse picking.
When the Complete N55 Kit Is the Right Purchasing Unit
This product is intended for buyers who require the complete shaft, actuator and bearing combination. It should not be confused with a universal workshop kit or an automatic recommendation to replace every Valvetronic component.
The complete-kit format is useful when:
- A distributor wants one approved stock code for the shaft, motor and six bearings
- An engine-repair programme specifies the full assembly
- A private-label buyer requires clearly defined kit contents
- A repeat order needs a stable packing list and label description
The professional repairer or buyer remains responsible for determining the required replacement scope after inspecting the existing components.
N55 Application and Repair-Scope Confirmation
BMW N55 identifies an engine family, not a complete purchasing specification. Before quotation, buyers should confirm:
- The original 11377589883 shaft reference or catalogue record
- The N55 engine version and vehicle production information
- The required actuator-motor reference
- The requirement for six needle bearings
- Whether any seals, bolts or installation parts are requested separately
- The final packaging and label scope
If the original number cannot be read, provide the VIN, catalogue screenshot, component photographs or a sample for comparison.
Interface and Completeness Checks
Because the shaft, actuator and bearings operate as related parts of the Valvetronic mechanism, the kit should be checked as a complete purchasing unit before dispatch. Relevant checkpoints include:
- Verification of the 11377589883 shaft reference
- Visual condition of the eccentric surfaces and geared drive area
- Actuator connector and mounting-interface inspection
- Needle-bearing identity and quantity check
- Comparison with the approved packing list
- Product-label and carton verification
Buyer-specific dimensional reports, batch records or inspection documents should be requested during quotation so their availability can be confirmed.
Distribution and Private-Label Considerations
For distributor catalogues, the product label should clearly state the N55 engine platform, the principal 11377589883 shaft reference and the actual contents of one shaft, one actuator motor and six needle bearings.
Neutral packing and buyer-specified labelling can be discussed according to order quantity and approved artwork. The minimum order quantity is five kits. Lead time, carton quantity, trade terms and documentation requirements are confirmed in the formal quotation.
Buyers consolidating BMW engine-parts purchasing can also review the BMW camshaft and Valvetronic product range.
