245B Bucket Hydraulic Cylinder | PN:4E6528 | Heavy-Duty Aftermarket Replacement
1.Product Overview
This heavy-duty bucket hydraulic cylinder is a professional aftermarket direct replacement exclusively designed for classic 245B large ex vator. As the core hydraulic executive component of digging attachment, it provides powerful bucket curl and dump force for quarry rock grabbing, large-s le earthmoving, bulk material loading and heavy infrastructure construction. It is a key stocked spare part for heavy equipment overhaul shops, second-hand large ex vator rental fleets and cross-border spare parts suppliers specializing in old T B series heavy machinery.
All manufacturing procedures strictly follow original vintage OEM drawings and dimensional standards. Mount lug spacing, pin hole diameter, bushing inner size and hydraulic port layout fully match part number 4E6528. Plug-and-play installation without cutting, grinding or welding modifi tion on site, effectively reducing maintenance labor cost and avoiding long construction downtime used by machine failure.

Common Customer FAQ
Q1: n this bucket cylinder fit T 245D or other B-series ex vators?
A: Cross-model installation is not supported. Different T ex vator generations and models adopt exclusive OEM part numbers and unique lug mounting geometry without interchangeability. Always double-check your full machine model before submitting orders.
Q2: Does standard shipping package include the matching seal repair kit?
A: Standard packaging only contains the complete bucket cylinder assembly. The dedi ted 4E6528-KIT seal kit must be purchased separately, and we offer a discounted bundled quotation for clients ordering cylinder and seal kit together.
Q3: What anti-rust and anti-collision protective measures are adopted for long-distance ocean transportation?
A: Anti-rust hydraulic fluid is fully injected into both front and rear cylinder chambers to block 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.
Q4: Are tiered volume discounts available when purchasing a full boom, arm, bucket cylinder set for T 245B?
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 minimize overall international logistics expenses for large batch purchases.
Q5: What after-sales techni l support n I receive if oil leakage develops within the 12-month warranty period?
A: Kindly supply clear photos showing the exact leakage position plus your ex vator serial number for verifi tion. We will deliver free replacement seal components and detailed step-by-step remote maintenance guidance promptly to resolve leakage faults without halting quarry production schedules.
