Input Shaft Oil Seal for Ford 40 Series and Late TS Series Transmission Drop Box SKU: QT4907

When oil starts leaking from your transmission drop box area, a worn input shaft seal creates more than just a messy puddle. This small but critical seal failure allows transmission fluid to escape while letting dirt and moisture infiltrate your gearbox, setting up expensive internal damage down the road.

Why This Seal Matters

• Precise 36x50x10mm dimensions ensure proper fit in late TS series drop box housings
• Quality rubber compound withstands transmission heat and hydraulic pressure cycling
• Prevents costly transmission fluid loss and contamination from field debris
• Direct replacement design eliminates guesswork during installation

A failing input shaft seal that goes unrepaired leads to low fluid levels, overheating, and gear damage that can cost thousands to rebuild. This seal restores factory protection to keep your transmission running smooth and leak-free through demanding farm operations.
