Transmission Seal for John Deere 40-50 Series Hi-Lo Unit SKU: QT59258

When your transmission Hi-Lo unit starts leaking gear oil on the ground, you lose both lubrication and the precise hydraulic pressure needed for smooth shifting between ranges. This 45x55x7mm seal restores the factory seal integrity your John Deere 40-50 series needs to keep transmission fluid where it belongs while preventing dirt contamination that damages internal components.

Why Genuine Quality Matters

• Precision 45x55x7mm dimensions ensure exact fit in Hi-Lo unit housing
• Heat-resistant compounds handle transmission operating temperatures without breakdown
• Double-lip design prevents gear oil loss while blocking contamination ingress
• Durable construction withstands hydraulic pressure cycling during range shifts

A leaking Hi-Lo seal means more than just messy floors - it compromises the hydraulic pressure needed for smooth range shifting and allows contamination that shortens transmission life. S&H Parts has been helping farmers keep their John Deere tractors running since 1969.
