Whether you are doing a routine check-up or bearing replacement due to wear and tear, you need to get familiar with the process. Wondering how to change spindle bearings on Kubota mower?

Gather the necessary tools and materials

Before you begin the Kubota spindle bearings replacement, having the essential tools and materials in your hand will simplify the process. You will likely need:

  • Replacement bearings
  • Socket set
  • Torque wrench
  • Grease gun
  • Safety goggles
  • Gloves
  • Cleaning supplies

Prepare for the replacement

Whatever task you are planning to tackle, always prioritize safety. Use protective gear like safety goggles and gloves to prevent injuries, as well as shield your eyes and hands from potential hazards. Once fully equipped, you can begin the preparation.

Start by parking your Kubota mower deck on a flat surface. Engage the parking brake and turn off the machine’s engine for safety. If necessary, you can also use a jack or lift to have easier access.

Remove the mower deck

For better access to the mower deck bearings, you need to detach the mower deck safely from the mower. Start by disconnecting the deck from the mower by removing the mounting bolts, connecting rods, and cables. You will also need to take out the blades with an impact or socket wrench.

Identify and extract the old bearings

Once you remove the mower spindle, it is time to locate the old bearings and extract them. Use a bearing puller or a socket set to loosen and remove the bolts or retaining clips that secure the bearings in place.

After you remove the fasteners, carefully pull the bearings out of the spindle shaft. We recommend taking note of their placement so that you can install the new ones properly later on.

Clean the area 

Before you install the new mower deck bearings, take time to clean the mower deck’s spindle and its surrounding area thoroughly. Make sure to remove any dirt, debris, or old grease using suitable cleaning supplies. 

Install and secure the new bearings

Next, apply a thin layer of grease on the shaft to aid the installation of the new ones and ensure smooth rotation. Carefully slide and press the new bearings onto the spindle and make sure they are seated correctly. Once the new bearings are in place, reattach any bolts or retaining clips in order to secure them firmly. To tighten the fasteners, use a torque wrench.

Reattach the mower deck

Once you replace the spindle bearings, you can reattach the mower deck to the mower. Align the deck with the frame of the mower and rejoin the connecting rods and cables. Tighten the bolts to secure the mower deck in place.

Test and adjust

Before your Kubota mower deck goes back into operation, you must ensure that everything functions correctly. Start the mower’s engine and engage the blades to see if everything works well. 

Check for any unusual and rough sounds, or vibrations, that may indicate issues with the bearings. If needed, you can also adjust the blade alignment or tension to optimize performance.
