Electric Motor Pricing: The Last 10 Years

In the last 10 years the price of electric motors whether they are used for pool pumps or not have gone up very high. Back in 1994 the price for a replacement 1.5 HP electric motor was way under the $100 mark. Today in 2011, the price for some replacement electric motor have exceed to the tune of $300+ and up.

If you rebuild the pool pump motor yourself you can do so with about $40 dollars in replacement parts and a few hours of your time. if you are not handy, it is still cheaper to have a pump repair shop or an online pump repair service rebuild the pump and motor for you. The average price of a pool pump rebuild is around $149.00. The repair shop will change your electric motor bearings, replace your seal and then also check your motor windings, clean and spray paint the pump.

So what you want to ask yourself is, “isn’t it worth it to repair or have someone repair my pump for less then half the price vs spending all that money?”

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:

Hammer

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.

Screwdrivers

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.

Nut-drivers

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.

Electric Motor Repair Checklist

Here is a quick checklist to see if you have enough time and tools to rebuild your electric pool pump motor.

    Pool Has been chemically treated
    Have enough time to rebuild the pump

Then Remove the motor from the pump housing by sliding it out. Next, Remove the Diffuser by pulling it off or, if necessary, lightly prying it off with the help of a flat head screwdriver. (Note: if the diffuser is not on the end of the motor- it will be inside the pump housing). The Impeller should now be visible.

1oneSecure Motor Shaft

Secure motor shaft from turning by sliding wrench on motor shaft

Secure the Motor Shaft. The motor shaft must be secured to prevent it from turning so that the impeller can be unscrewed; To accomplish this you will be sliding the 7/16” wrench onto the flat sides of the motor shaft- Go to the rear of the motor, remove the cover and unscrew the bracket screw holding the large black capacitor in place- (note- leave the capacitor’s wires attached, it is sufficient simply to move the capacitor out of the way). Electrical Warnings- To avoid a possible shock, lay a screwdriver across the two leads to short out the capacitor. ii. Grab the motor shaft with the 7/16” wrench to secure it from turning.

1oneRemove The Impeller

Remove the Impeller- With the wrench securing the motor shaft to keep it from turning, you can now turn the impeller counter-clockwise to remove. The two parts of the Pool Pump Shaft Seal should now be visible; one part, the white ceramic seal, on the seal plate on the shaft, and the other, the spring-seal, on the pump impeller. Note the way the spring seal is on the shaft, as it will need to be re-installed the same way. Inspect the threads of the impeller, if they are badly worn, you will need to replace the impeller.

1one Remove The Shaft Seal

Diving in your cool swimming pool on a blazing sunny day can create a whole bunch of happiness, but when your swimming pool pump and motor is worn-out, pool diving will become no choice for no one. When your pool pump fails, your water stops circulating, and dirt starts getting in your pool. 

It is worth knowing that your pool pump or motor is not useless when it is no longer functioning. You can choose to either repair or rebuild. In situations when repair did not work, you can reconstruct the entire chassis of the motor. Stripe down the whole engine, re-insulate, install new bearings, test, and finish the body with fresh coat paint. 

Apparently, most used pool pump motors you see in the market have been rebuilt to function like a new one. This is a new technique to help you get into your pool quickly.

This guide will show you the steps involved in replacing your pump motor.

Can I Repair A Pool Pump Motor?

Your pool pump most times does not necessarily require a rebuild or a complete replacement. Sometimes a repair from a professional mechanical engineer would get it back to life. 

Generally, you should consider repairing your pool pump if the cost of getting a new one is higher than the repair cost or the pump’s life span is less than 5 years. As long as  the repair cost is less and it is not close to the end of life, you can go for a repair.

First, before you opt for a repair, you need to find out the problem. Is it the capacitor, bearing or an electrical shortage? If you are handy enough and know how to fix a pool pump motor, this could be an easy problem to analyze and solve. If you are not, you would need to get a tech to investigate and find the actual cause.

How to Avoid Costly Pool Motor Repairs

Electric motors are essential for your pools and are brain power in your pool pumping system. Most people tend to ignore the regular maintenance of their engine for years until the motor completely shuts down. This will incur a high cost that might not be favorable to your pocket. 

To avoid the cost of swimming pool motor repair, you would need to do the following;

Test the Electrical System of the HVOC Motor

This is a critical aspect that needs to be investigated to help evaluate the electrical failures of your motor. It also helps determine if the electric current is flowing as supposed. 

Regular Oil Check 

Oil is vital in any rotating machine. It helps lubricate the engine, reduces temperature and friction. Check for contaminated or low oil before you kick off the pump.

Clean Up the Motor Regularly

As the motor rotates, it gathers dirt and leaves, which clogs inside the engine. When this happens, the efficiency of the fan is reduced and could cause severe damage to the motor. So, unclog regularly. 

Conclusion

Whether you are rebuilding, replacing, or repairing your swimming pool motors, never allow the engine to go damaged at the point to incur unnecessary cost. Follow the maintenance procedure outlined. They will help you keep your motor functioning for many years.
