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.

2.Core Techni l Parameters

Distinctive Product Competitive Advantages

1. 100% OEM Dimensional Exact Match Only for T 245B Vintage Ex vator
   Part No.4E6528 is exclusive to T 245B bucket cylinder assembly. All connection dimensions fully repli te genuine original T components, seamlessly matching bucket linkages and factory hydraulic pipelines. Assembly dislo tion and subsequent premature seal aging, oil leakage risks used by forced installation are completely eliminated, perfectly adapting to the assembly structure of aged 245B machines.
2. Quarry-Focused Reinforced Anti-Impact Structure for Old Heavy Machines
   The cylinder barrel and integrated st lug plates adopt targeted thickness reinforcement, customized for harsh quarry working conditions of 245B old large ex vators, including long-term alternating heavy loads and frequent sharp rock collisions. Compared with ordinary thin-wall universal aftermarket cylinders, this model has greatly extended service life and stable performance under continuous heavy rock digging.
3. Two Independent Pre-Delivery Inspections Eliminate Hidden Failure Hazards
   Each finished cylinder undergoes two rigorous offline testing workflows. Full-stroke recipro ting fatigue testing simulates months of non-stop heavy rock ex vation to verify overall structural rigidity; extended high-pressure soaking airtight inspection s ns all internal and external vities to detect all oil leakage flaws. All unqualified units are fully filtered out before warehousing to avoid costly unplanned mine shutdown losses for end users.
4. Superior Cost Performance for Operators of Vintage Heavy Ex vator Fleets
   Genuine OEM spare parts for discontinued T 245B are s rce and high-priced. This aftermarket bucket cylinder reaches equivalent structural toughness, stable operation and service cycle at a much lower cost, greatly cutting long-term recurring maintenance expenses for mine repair workshops and rental companies with fleets of 245B ex vators.
5. Flexible Global Logistics Solutions Adapted to Diverse Client Delivery Needs
   All in-stock units n be dispatched within 3 working days upon payment confirmation. Air freight channels ter to emergency rush orders for sudden breakdowns in remote quarry zones; consolidated bulk sea rgo and full FCL container transport provide budget-friendly wholesale transport plans for machinery distributors covering mining markets across Afri , Southeast Asia, the Middle East and Latin Ameri .

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.
