It shows removing snap rings and bearings, cleaning the case, installing the new seal and gasket, and torquing axle case bolts to spec (17-20 ft-lbs). Best for owners tackling this exact repair themselves.
An owner-operator documenting a hands-on repair on their own tractor, including mistakes, rather than a polished or professional production.
The front axle wheel case knuckle seal fails over time, letting dirt and water in which deteriorates the rubber seal, causing gear oil to seep down the tire.
Jack up the tractor, remove the tire, separate the bevel gear case from the axle case, remove snap rings and bearings, replace the seal and gasket, then reassemble.
The 12 millimeter axle case bolts are tightened to 17 to 20 foot pounds, alternating from side to side.
