Good To Know

Q: What causes a PTO shaft oil seal to fail? A: The seal lip can wear or harden over time due to heat, age, or shaft wear, resulting in oil seepage and requiring replacement.

Q: How do I remove the old seal before installing this one? A: Use a seal puller or a small pry bar to carefully extract the old seal from its bore, then clean the seating surface thoroughly before pressing in the new one.
