PTO Shaft Oil Seal for Kubota
This PTO shaft oil seal is a direct replacement component designed to prevent lubricant leakage and contaminants from entering the rear power take-off assembly on compatible Kubota tractors.
Overview
This PTO shaft oil seal is a precision-engineered sealing component that fits the output shaft of the tractor's power take-off system. It serves to keep transmission oil contained while blocking dirt and debris from damaging internal components, ensuring the PTO operates reliably on models including the M8540 series. This PTO shaft oil seal is built to restore the integrity of the rear housing.

Good To Know
Q: What is the primary function of this PTO shaft oil seal? A: It prevents transmission oil from leaking out around the PTO shaft while keeping dirt and moisture from entering the rear axle housing. A worn seal can cause low oil levels and premature gear wear.
Q: How do I know this seal is the right one for my tractor? A: Confirm your tractor model and serial number against the listed compatible models, and measure the old seal's inner and outer diameter before ordering. This seal is meant for Kubota models in the M8540 series listed above.
Slight variation in finish or dimensions may occur between production runs, and fit can depend on serial number, so confirm compatibility before ordering.
