Rear PTO output shaft seal for Ford TW-series and 5000–8000 series tractors, along with several New Holland models that share the same transmission architecture, covering production from the mid-1970s through the mid-1990s. Dimensions are 2-15/16" I.D., 3-3/4" O.D., 1/2" width. Important: Ford used two different seal sizes on these platforms depending on build date and transmission variant — verify the OEM number and measure the original before ordering, as the wrong size will not seal correctly regardless of how carefully it's installed. Standard lip seal install; light oil on the lip and careful alignment over the shaft will prevent folding the seal during fitting.
