Rebuild Golf Cart Motor

Golf carts make it easier to trek the golf course with your equipment when you play a game of golf. Sometimes, the motor of your cart can run into problems and may need a tune-up. Rather than spending the money on a brand new motor, you can troubleshoot the problem and rebuild it yourself.

Disconnect all the components from your golf cart motor by undoing the motor mounts, muffler and cables, as well as the battery. Completely remove the motor and place it on a workbench.

Use a screwdriver to remove all of the bolts from the motor. If there is dirt buildup inside the motor, clean it all off and out with a cloth. Use the screwdriver's head to drive out any stubborn dirt or debris that may be difficult to remove with just the cloth. It is important to remove all of this because dirt can prevent your motor from properly cooling.

Remove the bolts from their sockets at the top and sides of the motor, underneath which the carburetor is located. Clean out any dirt you encounter inside. There may even be bolts hidden beneath the dirt, so be extra cautious.

Take the head off of the motor to view the cylinder and piston. Examine the piston and reach inside to check how tight it is. If it is loose, it will need adjusting.

Remove the cylinder by unfastening all the side bolts with your screwdriver. The bolts should be located at the bottom of each corner of the cylinder. Then, pull out the piston and examine it for any missing piston rings.

Use pliers with a 90-degree adapter to remove any broken piston rings from the piston. Then, replace these with new rings from your rebuild kit by lining up the ends of the rings where the grooves are. Insert the ring near the pin and gently work it around the piston.

Remove the motor's bearings, which are two small magnets. Also remove the gasket and then clean the area with engine cleaner. Let it soak for a few minutes, then use 400-grit sandpaper to smooth out the gasket's surface.

Replace the piston and bearings and add transmission oil inside to lubricate. Also, replace the base gasket as well, and add silicone gel to the base and cylinder. Push the gasket against the silicone so that it sticks to it. Add silicone to the top of the gasket to tighten its contact with the cylinder so that no oil can spill out. Coat the top of the cylinder with transmission oil.

Use a wrench to tighten all the nuts and bolts you previously removed, or replace them with new ones in your rebuild kit, if necessary. Make sure they are as tight as possible so as to avoid any oil spills.

Check for proper movement of the piston, and make sure the rings are properly aligned with the exhaust port of the motor. Note that the side of the piston with the hole goes into the carburetor of engine, while the solid side should be aligned with the exhaust port.

Replace the head gasket and tighten the bolts securely to its top. Place the washer in its spot in the center.

Put the motor back into the golf cart. Add oil (less than 10 millimeters) so that the piston and cylinder get extra lubrication.

Test out your golf cart to ensure that the motor is working properly.
