Compatible Models

We do our best to list all compatible models. Although this may be the part you need, your exact model may not appear below.

Compatible equipment / model
  • Kubota M7030, M7040 and M7060
  • Kubota M8030, M8540 and M8560

  • Kubota M5040, M5140, M6030 and M8200 applications only where the same seal is specified

Product Overview

Oil running down a front hub or appearing around the axle housing may point to a failed seal, but the exact leak location matters. Bearing play, a scored shaft, blocked vent, worn bushing, or damage from wrapped material can make a fresh seal leak again.

The seal retains front-axle lubricant at the matching rotating joint. Similar M-Series axles use several seals, so model names alone cannot identify the correct position.

Match 33740-80290, dimensions, lip and outer-shell design, parts-diagram location, front axle option, tractor model, and serial number.

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: Can I replace the seal without checking the bearing? A: You should check it. Axle movement can quickly damage the new seal.

Q: Does it fit every M7040? A: Serial number, axle configuration, seal position, and dimensions must be verified.

Q: Why is oil coming from the same area after repair? A: The shaft, vent, bearing, installation depth, or another nearby seal may be the real cause.

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.
