Tools You Will Need To Repair / Rebuild Electric Motors

You will need some basic hand tools and also some specialty hand tools as well to rebuild your electric pool pump motor. Some of these tools are expensive but also can be rented or borrowed from a friend or neighbor.

Specialty Tools Needed:

Bearing Puller

You will need a bearing puller to pull the bearings from the motor armature / pump motor shaft. You can either buy one or rent one from a tool rental store.

Arbor Press / Bearing Press Tool

You will either need an arbor press or a bearing press tool to replace the bearings. Most local auto parts stores will have a bearing press tool you can either buy or rent. You can also stop by a local machine shop and ask then to press on the bearings for you. You may even know someone with an arbor press. Ask around.

Hand Tools Needed:


You will need a basic hammer to bang the end bells free from the motor casing. If you have a ball peen and a rubber mallet that would be a perfect set up for the electric motor repair.


You are going to need both a Philips head and a flat head screw driver, in the #2 (medium tip ) and #3 (large tip) sizes.


If you have a nut driver set that would make your life so much easier when repairing the pump Vs trying to use quarter inch sockets to remove the motor through bolts. i would suggest that you go out and borrow or buy a nut driver set because sometimes if you use brute force like with a socket you may snap the through bolt. If you snap the through bolt of in the end bell, you still will be able to repair the moor but you just created more work for yourself because no you will have to drill that bolt out.

Open End Wrench Set

You are also going to need an open end wrench set. Just a basic set sizing from 3/8″ to 5/8″ will work most of the time.

Preparing For The Pool Pump Motor Rebuild / Overhaul

If your considering rebuilding your electric motor and pump you should also think about the amount of time that your pump is going to be removed from the filter system. If the weather is hot and your pools chemicals are not balanced correctly you could wind up with a green pool.

The best thing to do is to make sure that your water chemistry in your pool is all in the proper ranges.

As a quick tip:

Your ALK should be between 80 – 120 PPM , Your PH should be between 7.2 – 7.4 PPM and your Chlorine should be around 2.3 PPM.

Then you will also want to run the pool filter system continuously for 24 hours before you remove the pump.
