Cummins Engine Parts - New and Used

Cummins Components and Spare Parts

Where is the Cummins Engine Serial Number (ESN) located?

The ESN on Cummins engines is applied in several ways to allow reading even in difficult operating conditions:

Data Plate: This is the most reliable source of information. It is usually located on the side wall of the engine block or on the timing gear housing.

Upper Engine Components: In newer series (e.g., ISB, QSB), the data plate may be placed on the side of the valve cover or on the intake manifold.

Stamping on the Block: If the data plate is missing or illegible, the serial number is often stamped directly into the metal on the engine block, usually near the oil cooler or above the oil pan.

Machine Documentation: The engine identification number is always repeated on the main data plate of the construction machine (e.g., excavator, loader) in which the Cummins unit is installed, as well as in the service manual and warranty documents.

Proven Components for Cummins Engines

In the transport and construction industry, downtime is not just a cost; it represents real contractual losses. Buying Cummins engine parts from an unverified source is a risk not worth taking. Our history at Wibako didn't start at a sales desk, but in the workshop, during real major overhauls. Every day, our mechanics diagnose, disassemble, and remanufacture Cummins units – from the popular B and C series to the powerful QSX15 engines.

It is this years of workshop practice that has allowed us to select a range of parts that we vouch for with our own name. Over the years, we have tested dozens of suppliers. Today, in Wibako's range, you will only find components that have passed our internal load tests and lasted as long as factory-fitted components. The rule is simple: if a particular element has not proven itself in our service center, it will never reach your machine.
 

From Experience:

We received a Cummins QSB 6.7 engine that suffered turbocharger seizure after just 300 operating hours. The cause was a cheap, unbranded oil filter replacement that could not withstand the operating pressure and led to contamination of the lubrication system. This failure cost the owner over a dozen thousand PLN - many times more than the savings on the filter. This event confirmed our belief that at Wibako, we only offer components from proven OEM suppliers or originals. Rigorous quality verification is a standard at our company that protects your business from unplanned downtime.

Certified Supply Chain: Assurance of Premium Class Components

Why does the origin of Cummins parts matter?

The safety of Cummins engines depends on the supplier's reliability. We are an official and authorized partner of the Motorservice group and the Bosch brand, which guarantees access to certified components while bypassing intermediaries. Our status ensures direct distribution of parts from Kolbenschmidt and BF brands, which are factory-fitted in Cummins units. As a result, the pistons, bearings, and crankshaft elements we provide are 100% consistent with the manufacturer's technical documentation and meet rigorous material standards.

A key pillar of our offer is cooperation with Bosch in the field of advanced Common Rail fuel systems. We provide access to the precision injection equipment necessary to maintain Stage V emission standards and optimal engine performance. Choosing Wibako as a certified partner means certainty of the parts' origin, full engineering support from manufacturers, and elimination of risks associated with components from outside official trade. We focus on premium class components that guarantee the maximum lifespan of Cummins units after overhaul.
