225-4625 Hydraulic Cylinder Seal Kit for Caterpillar Excavators E-330D 336D Bucket Repair
As a specialized manufacturer of excavator hydraulic seal kits, we provide high-precision, factory-grade replacements for critical Caterpillar machinery. The Bucket Cylinder on the CAT E330D and 336D series excavators is subjected to extreme forces during heavy-duty digging and loading. Our BUCKET SEAL KIT, often cross-referenced with OEM part number 225-4625, is the reliable, factory-direct solution for wholesale buyers seeking superior quality and value.
The Critical Need for a Premium 225-4625 Bucket Seal Kit
The Bucket Cylinder is arguably the most stressed hydraulic component on the excavator. Seal failure in this cylinder can lead to:
1.Loss of Breakout Force: Internal fluid bypass directly reduces the power available for digging, severely impacting productivity.
2.Rapid Contamination: The proximity to the ground makes the bucket cylinder highly vulnerable to dirt and debris, which quickly destroy internal components if the wiper seals fail.
3.Increased Downtime: Repairing a failed bucket cylinder is costly and time-consuming, making preventative maintenance with a high-quality seal kit essential.
Our 225-4625 Bucket Seal Kit is a complete, multi-component solution engineered for maximum durability and sealing performance, restoring the cylinder to its original specifications.
