Version 1 (Multi-Component Application Focus)

Excavator hydraulic system overhauls require the comprehensive seal kit that includes 4I3665 for arm and boom cylinders. The bucket center joint sealing depends on 4I-3665 to prevent cross-contamination between circuits. When servicing swing motors or travel motors, part number 7079824480 pairs with 4I3665 for complete rotary sealing. The 707-98-24480 kit specifically addresses axial piston motor leakage in excavator travel drives. Boom lift and arm curl functions benefit from 4I-3665 because it maintains consistent pressure across all actuators. Center joint rebuilds using 7079824480 and 4I3665 eliminate internal bypass between hydraulic ports. Excavator technicians stock 707-98-24480 alongside 4I-3665 to cover both motor and cylinder applications.

Version 2 (Motor & Joint Focus)

Travel motor and swing motor repairs on excavators often specify seal kit 4I3665 for rotating group sealing. The center joint assembly requires 4I-3665 to maintain lubrication between upper and lower structures. Part number 7079824480 (also listed as 707-98-24480) contains specialized seals for axial piston motor valve plates. When rebuilding the bucket center joint, install 4I3665 to prevent oil mixing between supply and return lines. The boom cylinder and arm cylinder share 4I-3665 as the common sealing solution across multiple bore sizes. Excavator loader hydraulic systems using 7079824480 and 4I-3665 show reduced swing motor drift. Every 707-98-24480 kit includes O-rings and backup rings that complement 4I-3665 in high-pressure ports.
