316FL Hydraulic Bucket Cylinder for Excavator Spare Parts 385-2917 3852917

This heavy-duty bucket hydraulic cylinder is a fully interchangeable aftermarket component tailor-made for 316FL mid-size excavator. Serving as the core power actuator of digging attachments, it delivers stable bucket curling and dumping power for residential foundation works, road overhaul, pipeline excavation, landscaping and small aggregate yard loading. It ranks as a must-stock spare part for urban equipment repair garages, mid-volume compact digger rental fleets and cross-border spare parts vendors focusing on FL new-generation medium excavators.

All manufacturing standards strictly follow official OEM technical blueprints. Mount lug pitch, pin hole bore, bushing inner diameter and hydraulic hose port angle are fully consistent with dual part codes 385-2917 and 3852917. Zero cutting, grinding or welding rework is needed during field fitting, which greatly cuts maintenance labor cost and minimizes costly construction idle time effectively.

1. Dual OEM Number Interchangeable Design Exact OEM Geometry for 316FL Medium Digger

   385-2917 and 3852917 are two coding formats referring to this identical bucket cylinder assembly. Every connection dimension fully repli es genuine factory components, seamlessly mating factory bucket linkages and matched hydraulic hoses. Assembly dislo ion and the subsequent premature seal aging, oil dripping risks brought by forced installation are thoroughly eliminated.

2. FL New-Generation Optimized Wear-Resistant Reinforced Frame

   Cylinder barrel and integrated cast lug plates adopt targeted thickness reinforcement customized for the high-frequency working mode of 316FL modern medium excavators. The upgraded structure withstands long-term medium cyclic loads and accidental collisions with concrete blocks, gravel and tree roots, achieving far longer service life than ordinary thin-wall generic aftermarket cylinders with simplified structures.

3. Two Independent Pre-Delivery Screening Blocks Hidden Failure Hazards

   Every finished cylinder undergoes two rigorous offline inspection workflows. Full-stroke recipro ing fatigue testing simulates all-day continuous digging operations to verify overall structural rigidity; extended high-pressure soaking airtight inspection scans all internal and external cavities to detect oil leakage flaws. All unqualified units are fully filtered out before warehousing to avoid unexpected construction shutdown losses for end users.

4. Outstanding Cost Efficiency for Mid-Scale Excavator Fleet Owners

   This aftermarket bucket cylinder reaches the same structural toughness, operating smoothness and service cycle as authentic OEM spare parts at a remarkably lower unit price. It drastically cuts long-term recurring maintenance costs for independent repair garages and rental companies operating multiple 316FL fleets.

5. Flexible Global Logistics Solutions Adapted to Varied Client Delivery Needs

   All ready-stock goods can be shipped out within 3 working days upon payment confirmation. Air express channels er to emergency rush orders for sudden site breakdown repairs; consolidated bulk sea cargo and full FCL container transport provide budget-friendly wholesale transport plans for machinery distributors covering Africa, Southeast Asia and Middle Eastern municipal construction markets.

Our factory holds more than a decade of dedi ed R&D and mass production experience in hydraulic cylinders for FL series new medium excavators, including the mainstream 316FL model. We operate a complete integrated production chain covering heavy precision forging, deep inner honing, integral heat treatment and automatic chrome plating, equipped with professional load simulation test benches to repli e real construction working conditions and continuously optimize product anti-impact durability. Our aftermarket hydraulic cylinder lineup is exported globally all year round, gaining consistent positive evaluations and stable long-term cooperative relations with worldwide construction machinery spare parts distributors, thanks to precise model matching and steady uniform quality output.

A: Cross-model installation is not supported. Different excavator generations and models carry exclusive OEM part numbers and unique lug mounting geometry without interchangeability. Always double-check your full machine model before submitting orders.

A: Standard packaging only contains the complete bucket cylinder assembly. The dedi ed 385-2917K seal kit needs separate purchase, and we provide discounted bundled quotations for customers ordering cylinder and seal kit together.

A: Anti-rust hydraulic fluid is fully injected into front and rear cylinder chambers to prevent internal corrosion; thick anti-rust grease is evenly coated across the entire exposed piston rod surface. The whole cylinder unit is wrapped in multi-layer heavy-duty waterproof PE film and secured inside reinforced thick plywood export crates to prevent scratches, impact deformation and moisture erosion during lengthy cross-ocean transit.

A: Yes. Orders for complete front working device cylinder sets qualify for progressive bulk preferential pricing. Consolidated full-container sea shipping service is also available to lower overall international logistics expenses for large batch purchases.

A: Kindly supply clear photos showing the exact leakage position plus your excavator serial number for verifi ion. We will deliver free replacement seal components and detailed step-by-step remote maintenance guidance promptly to resolve leakage faults without delaying construction schedules.
