Replacing your Grinding and Polish Wheel Motors on Your VE2Plus2 Edger
If this is your first time replacing your Diamond wheel or Polish wheel motor it can seem overwhelming or strenuous to accomplish. With years of usage some parts become rusty or frozen in place which become hard to dismantle or remove. As we have vast knowledge in this department we have put together some guidelines of doing this that can be helpful with the task at hand.

Step by Step Instructions:
Disconnect the main power to the edger before performing any maintenance.
Failure to do so could result in serious injury
The MAIN POWER switch is located on the front control panel. Turn the switch from ON to OFF and use a lock to be sure the machine cannot be energized while you are performing maintenance.
REPLACE THE SPINDLE MOTOR
Place the electrical control cabinet main power switch to the “OFF” position.
Remove the cover to the electrical connection box located on the motor being replaced. Tag and disconnect the wiring. (It may be helpful to refer to the wiring schematic drawing. Loosen the connector to the box and pull the wiring harness from the box.
If you are not confident in your ability to do the wiring, get a certified electrician to do this step for you.
1. From the front of the machine, remove the wheel compartment polycarbonate shield and remove the 4 wheel bolts and the wheel to expose the hub and slinger.
2. Loosen the central bolt securing the hub to the motor shaft and back it out a few turns (To prevent the motor shaft from turning, install a ¼-20 screw into the hub and wedge a screwdriver or small bar between the screw and the hub).
3. Remove or reposition the coolant lines if necessary.
4. Using a suitable puller, extract the hub from the motor shaft. After the hub comes loose, remove the puller and central bolt and pull the hub free from the shaft. Be sure to collect the shaft key and store it safely for re-use.
*** This step might be very difficult because of the tight space inside the wheel compartment. You might have to remove the whole motor and hub from the wheel compartment to get the hub out. Some hubs have never been taken off and are rusted. A hydraulic puller might be required for this step ** See video below of us doing this.
5. Remove the 4 nuts that are now exposed on the metal “slinger”. This slinger holds the rubber splash shield to the motor. Remove the slinger.
** The slinger might have some wear or deterioration. If this is the case it is recommended replacing it because this part is what helps keep the water from entering the motor **
6. From the back of the machine, remove the 4 bolts that hold the motor onto the spindle lifting post.
7. The motor can now be removed. Be careful not to damage the rubber splash shield as you pull the motor out.
** Some rubber splash guards are old and crunchy and it is recommended to replace them to ensure a nice tight seal around your motor **
8. The grind motor has a face mounted spindle housing assembly as part of the motor spindle assembly. Remove the four socket head cap screws from the front of the spindle housing assembly. Then separate the spindle housing assembly from the motor.
9. Install spindle housing assembly on the new motor using the four socket head cap screws to the front of the spindle housing
assembly. Install the motor on the spindle lifting post and secure using four lock washers and bolts.
** We have a very detailed video you can watch on how to do this correctly – see link https://hilditch-enterprises.com/diy-videos/ ***
10. Reconnect the electrical harness and wire motor following the tags applied in disassembly. Reinstall cover on electrical box.
11. At the front of the machine, position the rubber splash shield and slinger on four Allen head set screws and secure using four nuts.
(Note: the slinger has a hole in it. The hole must be facing down.)
12. Place key in keyway of the motor shaft and install the hub. Secure the hub to the motor shaft with the washer and bolt. Tighten the motor hub screw to 40 lbs-ft of torque. To prevent the motor shaft from turning, install a ¼-20 screw into the hub and wedge a screwdriver or small bar between the screw and the hub. Remove the screw from the hub. Position the wheel on the hub before tightening the Allen head screws to 20 lbs-ft of torque.
13. Put the main power switch located on the electrical control cabinet in the “ON” position.
