316FL Excavator Boom Hydraulic Cylinder 385-2913 3852913 Aftermarket 118mm Bore 1280mm Stroke

316FL Boom Hydraulic Cylinder | PN:385-2913 / 3852913 | Mid-Size Construction Aftermarket Replacement

Product Introduction

This heavy-duty boom hydraulic cylinder serves as a direct drop-in aftermarket component tailor-made exclusively for 316FL mid-sized excavator. As the core load-bearing lifting assembly of front working equipment, it delivers stable boom lifting, lowering and load retention power for urban foundation excavation, highway overhaul, pipeline construction and small aggregate stockyard stacking. It is a core stocked spare part favored by municipal machinery service shops, medium-scale compact digger rental fleets and cross-border parts suppliers specializing in FL latest generation medium excavators.

All production procedures are executed in strict accordance with ’s original OEM industrial design specifi ions. Mount lug center distances, pin bore diameters, bushing inner dimensions and hydraulic port routing fully correspond to dual interchangeable part codes 385-2913 and 3852913. No cutting, grinding or welding modifi ion is needed during on-site replacement, cutting maintenance labor overhead and minimizing costly construction downtime effectively.

Basic Product Information Sheet

Core Engineering Technical Parameters

Unique Product Competitive Advantages

1. Dual OEM Code Universal Matching Exact Fit for 316FL Chassis Layout

   385-2913 and 3852913 represent the identical boom cylinder assembly, fully compatible with all original mounting accessories of 316FL. Every connecting geometric size dupli es genuine factory components completely, seamlessly docking factory boom linkages and matched hydraulic pipelines. It thoroughly eliminates assembly misalignment issues that cause premature seal deterioration and persistent oil seepage triggered by forced installation.

2. FL New Generation Optimized Reinforced Anti-Impact Construction

   Cylinder barrel and integrated cast lug plates adopt targeted wall thickness reinforcement customized for the high-frequency working mode of FL series mid-size excavators. It withstands long-term alternating medium loads and accidental collisions with concrete curbs, gravel piles and tree roots, delivering much longer service life than thin-wall generic aftermarket cylinders without structural reinforcement.

3. Two Independent Pre-Shipment Offline Screening Eliminates Hidden Failure Risks

   Each finished cylinder undergoes two separate rigorous testing workflows before leaving the factory. Full-stroke recipro ing fatigue testing simulates months of non-stop urban digging work to verify overall structural rigidity; extended high-pressure soaking airtight inspection scans all internal and external cavities to detect all potential oil leakage points. All substandard units are fully filtered out before warehousing to avoid unexpected construction shutdown losses for end customers.

4. Balanced Cost & Durability for Medium-Scale Excavator Fleet Operators

   This aftermarket boom cylinder reaches the same structural toughness, operation smoothness and service cycle as authentic OEM spare parts at a far more competitive unit price. It drastically cuts long-term recurring maintenance expenditure for independent repair garages and rental enterprises managing multiple 316FL excavator fleets.

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

   All ready-stock units can be dispatched within 3 working days upon payment confirmation. Air freight channels er to emergency rush orders for sudden equipment breakdowns on construction sites; consolidated bulk sea cargo and full FCL container transport provide budget-friendly wholesale transport plans for machinery distributors serving municipal construction markets across Africa, Southeast Asia and the Middle East.
