Learn How to Safely & Efficiently Remove an Electric Golf Cart Motor in 5 Easy Steps
Uninstalling an electric golf cart motor is necessary when all other repair options have been exhausted. The motor consists of three main parts: an outer cylindrical metal housing, a field coil and poles, and an armature that drives the wheels. If the motor housing or armature is damaged, you may need to replace the entire motor. Before you begin the process, make sure the new motor you purchase is compatible with the electrical system of your cart and follow the instructions in your service manual.
Begin by disconnecting the negative battery cable from the battery terminal with an insulated wrench. After the cable is secure, remove all wires from the motor, and if applicable, unclip the speed sensor wire from the end of the motor.
To remove the motor from the axle, use a wrench to loosen the bolts that secure the motor to the housing, and set them aside. Take care not to damage the splines located around the wheel while attempting to slide the motor off. If extra access is needed, such as removing the roof, seats, chrome floor guards, floor mats, or rear body panel, do so to gain access. Make sure to jack up the rear wheels and use jack stands for safety.
If you need to disassemble the motor, remove the bearing cap or magnet and two to four bolts from the commutator cover located at the end of the housing. Pull off the cover and slide out the armature, and use this opportunity to also clean and remove dust and debris from the inside. Measure the length of the armature brushes and check against the manufacturer’s specifications. If worn down to the minimum length, replace them.
To reassemble, begin by sliding the armature back into the motor housing and securing the bearing cap or magnet. Replace the bolts and the commutator cover. Once the motor is reassembled, slide it back onto the axle, carefully lining up the splines and tighten the bolts that secured it to the axle housing. Finally, replace the speed sensors, if needed, reattach the wires, and reconnect the negative battery cable.
In conclusion, uninstalling an electric golf cart motor needs to be taken seriously and with caution. The process can be made easier by reading the service manual, having the right tools, making sure the new motor is compatible, and disassembling the motor when extra access is needed. Make sure to check the length of armature brushes and remember to always use safety equipment when necessary.
