Spare part 4011502 Single head gasket set (Cummins)
The Cummins Single Head Gasket Set 4011502 4012662 is a genuine OEM replacement designed for optimal performance and reliability in Cummins engines. This gasket set is an essential sealing component for the cylinder head, ensuring a secure and leak-free connection between the engine block and cylinder head. Crafted from high-quality materials, it is built to withstand extreme pressures and temperatures encountered in heavy-duty engine applications.
The Cummins Single Head Gasket Set 4011502 4012662 is engineered to meet strict OEM specifications, guaranteeing perfect fitment and compatibility. It helps maintain proper compression and prevents the leakage of coolant, oil, and combustion gases. This precision-made gasket set minimizes the risk of engine overheating, poor performance, and costly repairs, making it a vital maintenance part for long-term engine health.
This model, originally supplied under part number 4011502, has been superseded by part number 4012662. The updated version offers the same exceptional quality with possible improvements in durability and material composition. The gasket set is specifically designed for use in Cummins engines and is a key component when performing cylinder head repairs, rebuilds, or overhauls.
Weighing just 0.001 kg and measuring 2.5 × 2.5 × 2.5 cm, the kit is compact yet essential. It comes as a complete kit for the cylinder head, ensuring you have the required sealing components for the job. This part is most commonly used in maintenance schedules or during major engine repair work, where precise sealing and performance reliability are critical.
Choosing genuine Cummins parts like the Cummins Single Head Gasket Set 4011502 4012662 ensures your engine operates at peak efficiency. Aftermarket alternatives may compromise on fit or material quality, potentially leading to early failure or reduced performance. With this OEM gasket set, you can maintain the integrity of your engine’s design and performance standards.
We offer competitive pricing, fast delivery, and a global distribution network for Cummins spare parts. Whether you are a maintenance engineer, fleet operator, or engine rebuilder, this gasket set delivers the dependability and precision you need for your Cummins-powered machinery.
Why Cylinder Head Gasket Sets Fail
Cylinder head gaskets are subjected to repeated thermal cycling, high combustion pressures, and constant exposure to coolant and oil, so even a genuine OEM gasket set has a finite service life and is routinely replaced during scheduled cylinder head repairs, overhauls, or when a compression or coolant-leak fault is diagnosed. Common failure indicators that call for gasket replacement include visible coolant or oil weeping at the head-to-block joint, a persistent drop in compression on one or more cylinders, white exhaust smoke suggesting coolant intrusion into the combustion chamber, or coolant contamination visible in the engine oil. Replacing the full gasket set — rather than a single gasket in isolation — ensures every sealing surface disturbed during a head removal is renewed at the same time, avoiding a repeat teardown shortly after the first repair.
Installation Guidance
Correct installation of a cylinder head gasket set depends on clean, properly resurfaced mating faces on both the block and the cylinder head, correct torque sequence and torque values applied in the stages specified by Cummins’ service literature for the specific engine model, and use of the exact gasket set matched to that engine’s block and head configuration. Reusing an old gasket, substituting a generic aftermarket part not matched to the OEM specification, or skipping the correct torque sequence are the most common causes of early repeat failure after a head gasket job, which is why genuine, correctly identified OEM part numbers matter as much as the installation workmanship itself.
Why Genuine Cummins Parts
A genuine Cummins gasket set is manufactured to the exact material specification, thickness, and sealing-bead design validated for the engine platform it was designed for, which affects both the initial seal quality and how the gasket behaves under repeated heat-up and cool-down cycles over the engine’s working life. Because superseded and re-numbered part references are common across the Cummins parts catalog as designs are updated, confirming the correct current part number against the engine’s serial number and existing parts history is an important step before ordering, and Seven Star LLC can assist with that cross-reference as part of the quotation process.
Typical Applications
This gasket set is used wherever a Cummins engine of the corresponding platform undergoes cylinder head service — commonly on generator sets, marine and industrial power units, construction and material-handling equipment, and heavy-duty on-highway or off-highway vehicles running Cummins power. In Oman and across the GCC, where diesel gensets and heavy equipment operate for extended hours in high-ambient-temperature conditions, timely and correctly executed head gasket service is an important part of avoiding unplanned downtime, since cooling-system stress is generally higher in these operating conditions than in temperate climates, and gasket materials are worked harder across each thermal cycle.
Ordering Notes
Because this part has been superseded from 4011502 to 4012662, Seven Star LLC confirms the applicable part number against the customer’s engine serial number and any parts-list documentation before shipment, to avoid a mismatch between an older reference the customer may be using internally and the current genuine Cummins part actually required for their engine.
