Komatsu PC270LLC-6 Log Loader Boom Hydraulic Cylinder | PN:317-002-612 / 317-002-613 | Premium Aftermarket Replacement

1.Product Overview

This heavy-duty boom hydraulic cylinder is custom-engineered aftermarket replacement exclusively built for Komatsu PC270LLC-6 log loader excavator, a specialized machine designed for forest logging, timber hauling and wood stockyard operations. Serving as the primary lifting power assembly of the front logging attachment, it bears sustained heavy timber lifting loads, withstands frequent impact from tree trunks and uneven woodland terrain, and delivers stable boom hoisting and lowering performance. It is widely stocked by forestry equipment repair centers, logging fleet operators and cross-border spare parts suppliers focused on Komatsu log loader series machinery.

All manufacturing procedures strictly follow original Komatsu professional design blueprints for logging equipment. Mounting lug spacing, pin hole diameters, hydraulic port orientation and bushing matching dimensions are fully consistent with dual interchangeable part numbers 317-002-612 and 317-002-613. Direct bolt-on replacement is achievable on site without cutting, grinding or welding rework, greatly minimizing equipment downtime during forest operation maintenance.

Basic Product Information Sheet

2.Core Engineering Technical Parameters

Unique Product Competitive Advantages

1. Dual OEM Part Number Interchangeable Design for PC270LLC-6 Log Loader

   317-002-612 and 317-002-613 are two interchangeable factory codes for this identical boom cylinder assembly. Every connection dimension perfectly matches original Komatsu logging equipment components, seamlessly docking factory boom linkages and hydraulic pipelines. It eliminates assembly dislocation risks that trigger premature seal failure and persistent oil leaks caused by forced installation under heavy logging loads.

2. Forestry Custom Reinforced Structure Adapted to Harsh Logging Scenarios

   Different from standard construction excavator cylinders, this model adds extra thickness to barrel and lug plates targeting unique woodland working conditions: frequent heavy log lifting, repeated trunk collision and uneven ground vibration. The reinforced structure effectively resists long-duration cyclic heavy loads and irregular impact, achieving far longer service life than general aftermarket hydraulic cylinders for ordinary earthmoving machines.

3. Dual Independent Pre-Shipment Testing Eliminates Hidden Failure Hazards

   Each finished cylinder completes two rounds of strict offline inspection. First, full-stroke reciprocating fatigue testing simulates continuous all-day timber lifting work to verify structural rigidity. Second, extended high-pressure soaking airtight testing detects all internal and external oil leakage defects. All unqualified products are fully eliminated before warehousing to avoid costly work stoppages in remote forest zones.

4. High Cost Efficiency for Professional Logging Fleet Owners

   This aftermarket cylinder matches the structural toughness, operation smoothness and service cycle of genuine Komatsu OEM log loader spare parts at a much more competitive unit price. It drastically cuts long-term recurring maintenance costs for forest machinery repair yards and large logging companies operating fleets of PC270LLC-6 loaders.

5. Flexible Global Logistics Solutions for Remote Forest Equipment Clients

   All in-stock units can be dispatched within 3 working days upon payment confirmation. Air freight channels support emergency rush orders for sudden breakdowns in isolated logging areas; consolidated bulk sea shipping and full FCL container transport provide budget-friendly wholesale pricing for machinery distributors supplying forestry markets across Africa, Southeast Asia, North America and South America.

Common Customer FAQ

Q1: Can this boom cylinder fit regular PC270-6 construction excavators or other log loader models?

A: Cross-model installation is unavailable. PC270LLC-6 is a special timber loader with unique lug structure and stroke parameters different from standard PC270-6 earthmoving machines; other log loader models also adopt exclusive part numbers and dimensional designs without interchangeability. Always confirm your full machine model before placing orders.

Q2: Does the standard shipping package include the matching seal repair kit?

A: Standard packaging only contains the complete boom cylinder assembly. The dedicated 317-002-612-KIT seal kit needs separate purchase, and we offer a discounted combined quotation for clients ordering cylinder and seal kit together.

Q3: What anti-rust and anti-impact protection measures are used for long-distance ocean transportation?

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

Q4: Are tiered volume discounts available when purchasing a full boom, arm, bucket cylinder set for PC270LLC-6?

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

Q5: What after-sales technical support can I obtain if oil leakage occurs within the 12-month warranty period?

A: Kindly provide clear photos showing the exact leakage position plus your excavator serial number for verification. We will supply free replacement sealing components and detailed step-by-step remote maintenance guidance promptly to resolve leakage faults without delaying logging progress.
