Outer Half Shaft Oil Seal for Massey Ferguson 590 Series Epicyclic Unit SKU: QT3699800

A failing outer half shaft seal allows hydraulic fluid to leak from your tractor's epicyclic unit, leading to contamination of internal components and costly fluid loss that can damage your final drive. This precision-engineered outer half shaft oil seal provides reliable protection for the epicyclic unit, preventing hydraulic fluid loss and contamination while maintaining optimal rear axle performance.

Why This Seal Matters

• Precision dimensions 73x101.6x14.5mm ensure perfect factory fit in modified epicyclic units
• Maintains critical hydraulic fluid containment within the epicyclic final drive unit, preventing costly fluid loss and protecting internal components from dirt and moisture contamination
• High-grade rubber construction resists hydraulic fluid breakdown and temperature extremes
• Double-lip design provides superior sealing performance and extended service life

Installation requires rear wheel removal and partial disassembly of the final drive housing. Professional installation is recommended due to the complexity of final drive disassembly and critical torque specifications.
