Deere 270LC
This heavy-duty boom hydraulic cylinder is a direct interchangeable aftermarket component tailor-made exclusively for Deere 270LC mid-large long-track excavator. Serving as the core load-bearing lifting actuator of front working attachments, it delivers steady lifting, lowering and load-locking power for highway subgrade compaction, large building foundation excavation, stone yard bulk stacking and river dredging projects. It is a must-stock spare part favored by medium & heavy equipment repair centers, large excavation rental fleets and cross-border parts dealers focusing on Deere LC long-frame series construction excavators.
All manufacturing procedures strictly follow Deere official OEM blueprint standards and assembly tolerances. Mount lug center spacing, pin hole bore, copper wear bushing inner diameter and hydraulic oil port orientation fully match unique OEM part number AT264217. Direct bolt-on installation without cutting, grinding or welding modification on construction sites, effectively cutting maintenance labor costs and minimizing construction halt losses caused by hydraulic cylinder breakdown.

Part number AT264217 is exclusively developed for the long-track chassis of 270LC excavator. All connection geometric sizes fully replicate genuine Deere OEM components, seamlessly matching factory boom linkages and supporting hydraulic pipelines. It thoroughly avoids assembly offset issues that trigger premature seal aging and sustained oil leakage due to forced installation on long-frame reinforced machine structures.
Compared with standard short-frame excavator cylinders, this boom cylinder optimizes the wall thickness of cylinder barrel and cast lugs according to the long arm and heavy-load working characteristics of 270LC. It can bear long-term alternating heavy loads and accidental hard object impacts, with far longer service life than ordinary thin-wall universal aftermarket cylinders lacking targeted reinforcement design.
Each finished boom cylinder undergoes two rigorous offline testing workflows before leaving the factory. Full-stroke reciprocating fatigue test simulates months of uninterrupted heavy earthmoving work to verify integral structural rigidity; long-duration high-pressure soaking airtight inspection comprehensively scans all internal and external leakage points. All unqualified products are fully screened out before warehousing to prevent unexpected construction shutdown losses for end users.
Original Deere OEM spare parts for 270LC have high selling prices and slow supply cycles. This aftermarket boom cylinder reaches equivalent structural toughness, stable low-noise operation and service life as authentic factory parts at a much more competitive price, greatly reducing long-term repeated maintenance expenditure for repair workshops and large rental companies equipped with batches of 270LC excavators.
All in-stock goods can be shipped within 3 working days after payment confirmation. Air express supports emergency rush orders for sudden machine breakdowns at remote mountain construction and river dredging sites; consolidated bulk sea cargo and full FCL container shipping provide cost-saving wholesale transport plans for machinery distributors covering construction markets across Africa, Southeast Asia, the Middle East and Latin America.
Our factory owns more than ten years of professional R&D and mass production experience in hydraulic cylinders for Deere LC long-frame medium-large excavators, with the mature 270LC model as one of our core production lines. We operate a complete integrated production chain covering heavy precision forging, deep inner honing, integral heat treatment and automatic chrome plating, equipped with professional heavy-load simulation test benches to restore real construction and dredging working environments and continuously upgrade product anti-shock durability. Our heavy-load aftermarket hydraulic cylinder product line is exported globally all year round, gaining stable long-term cooperative trust and consistent favorable feedback from worldwide heavy machinery spare parts distributors, relying on precise long-frame model matching and stable uniform quality output.
