Montgomery ward tractor axle seal replacement.

Had a puddle of gear oil under my tractor that was coming from the axle tube. I figured the axle seal was at the end of the axle tube like a trucks so I ordered parts to fix it. Took the wheel off and found out the axle tube has to be pulled to get to the axle seal. The axle seal is inside where the axle tube bolts to the gear box. I had to drop the whole gear box to get to the seal. Going to start putting it back together today.
