322CL Hydraulic Bucket Cylinder for Excavator Spare Parts 174-8255 1748255

This heavy-duty bucket hydraulic cylinder is a direct bolt-on aftermarket spare exclusively produced for classic 322CL long track medium-heavy excavator, a discontinued C-series machine widely used in highway infrastructure, housing foundation excavation, medium quarry mining and bulk soil stockyard loading. As the terminal hydraulic actuator of front working attachments, it generates powerful bucket curl and dump breakout force to handle long-cycle heavy earthmoving jobs. It is a must-stock spare for second-hand equipment overhaul yards, medium-large excavation rental fleets and cross-border spare parts wholesalers focusing on vintage C-series excavators.

All manufacturing processes strictly follow original vintage OEM mining-grade drawings and precise assembly tolerances. Mount lug spacing, pin hole inner diameter, thick wear-resistant bronze bushing size and hydraulic port layout fully match interchangeable OEM part numbers 174-8255 and 1748255. No on-site cutting, grinding or welding modifiion needed during replacement installation, greatly lowering maintenance labor cost and avoiding long construction shutdown losses caused by scarce original cylinder spare parts for aging 322CL frames.

1. Exclusive Dual PN Matching Only for Discontinued 322CL C-Series Model

   Part numbers 174-8255 and 1748255 are interchangeable bucket cylinders custom-designed solely for 322CL, incompatible with 320C, 325C and other excavator series. All mounting geometric dimensions fully replie genuine vintage OEM components, seamlessly matching aged machine bucket linkages and original complete hydraulic piping layout. It thoroughly eliminates assembly offset issues that accelerate seal aging and cause persistent oil seepage from forced installation on slightly fatigued old heavy machine frames.

2. Vintage C-Series Heavy-Duty Targeted Reinforced Anti-Impact Upgrade

   Generic thin-wall universal aftermarket cylinders cannot sustain long-duration alternating medium-heavy loads of aging 322CL machines running quarry and large foundation projects. This model upgrades cylinder tube and cast lug wall thickness customized for the high-intensity working mode of discontinued C-series excavators, greatly extending service life and cutting frequent replacement costs for operators relying on second-hand heavy fleets.

3. Two Independent Pre-Shipment Offline Quality Screenings Eliminate Hidden Failure Hazards

   Each finished bucket cylinder undergoes two separate rigorous offline test sequences before exiting production workshops. Full-stroke reciproing fatigue testing simulates months of non-stop heavy earthmoving to verify integral structural bearing rigidity; extended high-pressure submerged airtight inspection detects every tiny internal and external oil leakage dead angle. All defective units are fully filtered out prior to warehousing to prevent costly unplanned construction shutdowns for contractors operating vintage heavy equipment.

4. Optimized Cost Performance for Owners of Discontinued C-Series Medium-Heavy Fleets

   Genuine OEM spare parts for long-discontinued 322CL are globally scarce with high retail prices and lengthy international supply lead times. This aftermarket bucket cylinder matches the structural load capacity, low-vibration stable operation and full service lifespan of authentic factory components at an economical unit price. It drastically reduces recurring long-term maintenance overhead for equipment overhaul hubs and rental enterprises managing batches of aging 322CL excavators.

5. Multi-Mode Global Shipping Solutions for All Overseas Construction & Mining Markets

   All ready-stock units can be dispatched within 3 working days upon payment confirmation. Air freight channels handle emergency rush shipments for sudden machine breakdowns at remote quarry and highway construction sites; consolidated bulk sea cargo and full FCL container transport deliver budget-friendly wholesale shipping packages for machinery distributors supplying construction & mining markets across Africa, Southeast Asia, the Middle East and Latin America.

Our production facility has over a decade of specialized R&D and mass manufacturing expertise focused on hydraulic cylinders for discontinued C-series medium-heavy excavators, with flagship 322CL as one of our core mature production lines. We operate a fully integrated closed-loop production workflow covering heavy precision forging, deep inner honing, integral heat treatment and automated thick chrome plating, paired with dedied medium-heavy load construction & quarry simulation test benches that replie real harsh jobsite environments to continuously optimize product shock resistance and long-term wear durability. Our heavy-duty vintage aftermarket hydraulic cylinder lineup is exported worldwide year-round, securing sustained long-term cooperative partnerships and consistent positive customer testimonials from global medium-heavy machinery spare parts distributors, thanks to precise discontinued C-series model compatibility and uniform strict stable quality control standards.
