307SSR Hydraulic Bucket Cylinder for Excavator Spare Parts 105-6459 1056459

This reliable aftermarket hydraulic bucket cylinder is custom manufactured as a direct interchangeable replacement for 307SSR mini excavators. As the key hydraulic execution component of the front working attachment, it drives the bucket to complete digging, material grabbing and dumping operations efficiently. It is widely applied in urban municipal renovation, landscaping, pipeline laying, small foundation construction and light earthmoving projects.

All products are strictly produced according to CAT original OEM technical standards, with fully consistent installation dimensions, pin hole spacing and hydraulic port layout. Direct bolt-on installation can be finished on site without cutting, welding or any secondary modification work.

1. Dual Part Number Interchangeable Fitment: 105-6459 and 1056459 represent the identical cylinder part, fully matching original assembly dimensions, seamlessly connected with bucket linkages and hydraulic pipelines to guarantee stable long-time continuous operation.
2. Optimized Light-Medium Load Reinforced Structure: Thickened cylinder barrel and connecting lugs are tailored for mini excavator frequent working scenarios, resisting periodic loads and minor collisions on construction sites and extending service life effectively.
3. Multi-Round Strict Pre-Delivery Inspection: Each finished cylinder undergoes repeated full-stroke cycle tests and high-pressure airtight leak detection, completely eliminating hidden risks of internal and external oil leakage.
4. Outstanding Cost Performance: Delivers the same stability and durability as genuine CAT spare parts, greatly lowering repeated procurement costs for repair shops and spare parts distributors.
5. Flexible Global Logistics Support: In-stock goods can be dispatched within 3 working days. Air freight meets urgent delivery demands, while sea freight is the most economical option for bulk wholesale orders.
