2578422 1417296/PI/SI 8T9042 2440953 Lift Tift Steering Hydraulic Cylinder Loader Seal Kit Arm Boom Bucket Seal Kit

Based on the part numbers you provided—2578422, 3195647, 8T9042, and 3195647-G—this hydraulic cylinder seal kit is engineered specifically for excavator arm, boom, and bucket applications. The kit 2578422 directly supports loader and excavator hydraulic seal requirements, ensuring reliable performance in heavy-duty cycles. For the boom circuit, part 3195647 delivers consistent sealing pressure, while the 8T9042 element complements the bucket cylinder assembly. Another configuration, 3195647-G, is included to match variations in cylinder gland designs. When rebuilding an excavator arm, the seal kit 2578422 should be cross-checked with 3195647 to avoid mismatches. The loader hydraulic seal setup often pairs 8T9042 with 3195647-G for extended service life. All four references—2578422, 3195647, 8T9042, and 3195647-G—are critical for maintaining leak-free operation in boom lift and bucket tilt functions. For a full cylinder reseal, order the kit containing 2578422, then verify compatibility with 3195647 and 8T9042. The suffix G in 3195647-G indicates a modified lip profile for higher pressure spikes. Always confirm that your excavator or loader uses the correct hydraulic seal type from the 2578422 family, and note that 3195647 supersedes older revisions except where 8T9042 is mandated by the cylinder bore size. Lastly, 3195647-G serves as a drop-in replacement for standard 3195647 when retrofitting buckets on compact loaders.
