Product Overview

Transmission oil running down the PTO stub or collecting inside the driveline guard can indicate a hardened or cut shaft seal. Shaft wear, bearing looseness, overfill, and a blocked transmission vent must be inspected before the new seal is installed.

The seal keeps lubricant in the PTO housing as the output shaft rotates. It cannot compensate for a groove or radial movement at the sealing surface.

Match 35822-80380, shaft and bore dimensions, lip profile, installation depth, tractor suffix, and serial number. Several different oil seals are used near the M9540 PTO assembly.

Compatibility Notice

Northline Parts does its best to list all known compatible models, but the correct part may fit an application that is not shown above. Model year, production date, serial number, engine or equipment specification, installed options, and previous repairs can change fitment. Match the original part, reference number, dimensions, connectors, mounting points, and product photos before purchase.

Frequently Asked Questions

Q: Why are several seals listed for M9540 tractors? A: The PTO and transmission contain multiple seal locations. Use the diagram and removed part to identify the correct one.

Q: Can I install it over a grooved shaft? A: A deep wear groove can quickly damage the new lip and may require shaft repair or replacement.

Q: Will it fit an M8540? A: Only if the parts catalog calls for the same 35822-80380 seal at the serviced location.

Q: Is this an original-equipment part? A: No. This is a new aftermarket product. Brand names and part numbers are used only to identify compatible applications.
