3195647-G 2976848 1137482/PI Hydraulic Cylinder Excavator Arm Boom Bucket Seal Kit

3195647-G 2976848 1137482/PI Hydraulic Cylinder Excavator Arm Boom Bucket Seal Kit

Version 1 (Technical Application Focus)

Service technicians repairing excavator arm cylinders often require 3195647-G to resolve leakage from boom or bucket actuators. The seal profile 3195647-G integrates wipers and rod seals specifically for loader hydraulic systems. For main cylinder rod drift, 3195647-G provides a complete replacement solution across  attachments. When rebuilding a bucket cylinder, 3195647-G matches the original extrusion gap tolerances. Another critical component, 2976848, addresses piston seal failures in loader lift circuits. Using 2976848 during boom cylinder overhaul prevents premature seal extrusion. The kit 2976848 includes buffer seals rated for high cyclic pressure on excavator buckets. For loader arm regeneration circuits, 2976848 demonstrates 30% lower friction than generic alternatives. Additionally, 1137482/PI serves mini excavator dipper cylinders with its compact polyurethane composition. The seal set 1137482/PI meets ISO 9001 standards for boom drift prevention. Operators of wheel loaders choose 1137482/PI for its abrasion resistance in bucket tilt functions. Finally, 1137482/PI is cross-referenced with OEM hydraulic schematics for swing cylinders.

Version 2 (Part Number Cross-Reference Focus)

Three distinct seal kits dominate excavator cylinder repairs: 3195647-G, 2976848, and 1137482/PI. For boom lift cylinders, 3195647-G replaces OEM numbers 12H-3346 and 20Y-1234. Loader bucket tilt functions rely on 3195647-G due to its double-lipped rod seal design. Excavator arm regeneration valves pair with 3195647-G to eliminate sponge control. A validated upgrade, 3195647-G uses HNBR material for high-temperature loader cycles. Meanwhile, 2976848 focuses on bucket cylinder piston sealing with PTFE backup rings. Hydraulic test benches confirm 2976848 withstands 5000 psi spikes in excavator breaker circuits. For loader Z-bar linkages, 2976848 reduces internal cross-port leakage by 18%. The kit 2976848 also fits boom lowering check valve housings. Lastly, 1137482/PI is engineered for mini excavator stick cylinders under 10 tons. Backhoe loader dipper sticks utilize 1137482/PI to prevent chrome rod scoring. Bucket cylinder dust wipers in 1137482/PI resist ozone cracking on demolition excavators. Tandem roller loaders benefit from 1137482/PI in their steering cylinder glands.
