Title: How to replace a Maytag - Amana washer water pump and belt.
Post by: AJ on August 27, 2007, 01:19:26 PM
In this example we are using a Maytag model NAV5800AWW washer. If your Maytag or Amana washer has a service panel on the bottom front of the washer it should be the same as the one we used in this example.

In the photo below we show you some of the parts we will be working with.
The front panel has already been removed. The screws that hold the front panel on are easy to find and were at points A & B. Once you remove the front cover this is what you should see.

Here are the steps.

1. Disconnect the power to the washer, unplug it!

2. Remove the front panel.

3. Remove the spring. This is one strong spring. In the video you will see me use the hook from another spring to pull it off. I would guess you do not have a old spring to use like I did. What I use to do before was to clamp a vise grip on the top of the spring. This will give you a good grip so you can pull the spring up and off.

4. Remove the pump hoses. In the video we did not have to worry about catching the water. If you do not want to get your floor wet have lots of towels under and around the hoses when you remove them. If the washer is full of water bail out as much of the water as you can first. You can also try to lay the drain hose on the back of the washer down low and drain the water into a bucket.

5. Remove the bolts at points 3 and 4, as shown in the photo.

6. Remove the wire harness plug from the motor. There is a little plastic tab on top the plug that you have to press down for the wire harness to release from the motor. You may need a flashlight to take a good look at it so you can see what your doing to get it unplugged.

7. Remove bolts at points 1 and 2 as shown in the photo.

8. Remove the drive belt from the main center pulley. You can do this by just rolling the belt off of the pulley.

9. Remove the pump and motor assembly from the washer.

10. Make note of how the belt goes around the water pump mounts and the belt idler before taking the water pump off.

11. Remove the three torx screws that hold the old water pump on the motor mount.



Once you have the motor and pump removed it can be a little tricky to get the drive belt back on the correct way before putting the new water pump back on.

In this photo we show you how the belt should be. Keep it in this position and put the new water pump back on.

Most often it is best to replace the drive belt anytime you have to take one of these apart to replace the water pump.

It will be much easier to replace the drive belt now then to have to do this all again down the road.

Please feel free to ask any question. :)

What size torx driver is needed for the water pump screws? I only need to replace the belt, but have to remove the pump housing to do it, of course.

Also, instead of removing the motor, I dropped the bottom of the washer off (and got more than I expected...); will I be able to get everything back together and functional?

That's a good question. I don't know off the top of my head.

I am thinking it's a t-15 or t-20, but can't say for sure right now.

Maybe another tech will know for sure.

I don't see why you would not be able to get it back together.

Keep us posted on how it goes.

I needed to replace a broken belt so I have no idea exactly how the belt goes back on.

When I go to remove the bolts as pointed out in step5(3&4 in the picture) - they just turn instead of coming out.  I've tried a drill, and a hand wrench to remove them, but they just spin instead of coming out like most bolts.  No I am not going 'in' with the drill or the wrench.  I can just barely see the back of one of the bolts and it does look like it is threaded.  Thanks for any help.

Here are images of what the back of these bolts look like -

You picked this topic up after 8 months...I believe we have given you the best advice so foar to solve the problem...obviously you did not read the first set of replies very well. as your pictures are the exact same ones that AJ  posted to help you.

You are trying to take out more than required. The only bolts needed to drop the motor/pump are the 2 bolt heads facing you at the motor sides and 2 above. Take the 2 lower ones out first!  If the top ones are slightly stripped as you imply, simply apply  hand pressure to the  metal hanger mount as you unscrew the bolt and it will come out. Use some force, girl :)

Thanks for the reply!  I am taking out the same bolts that AJ described in the post.  The images that I took of the rear of the bolts were to illustrate the back of the bolts.  Since I could not get a camera behind the motor mount bolt, it is one of the support frame bolts that the photo is of.  But the back of the bolt required to come out is the same style. 

I have taken another image of exactly what I am trying to do.  It illustrates the 4 bolts to remove, as well as where I am putting manual force to try and free the motor mount.  I have attempted to free this by adding hand(pulling pressure), jamming a crowbar in as good as I could, and trying to get a chisel/hammer/etc in there.  There is very little room to work with so it has not provided much added force if the bolt was stripped. 

Here is the additional image which should help: http://img4.imageshack.us/img4/8480/img0261edit.jpg

Thanks repair-man!  Also do you know where the video went for this post?  That might be very helpful but it seems as though it is not available at the given link any longer.

Success finally.  Three of the four bolts were stripped.  Ended up bending some metal and forcing the end of a hammer into each connection, and backed out the bolts.  Now I'm just hoping that the issue was the sock I found in the pump and breaking it!

Might as well replace the belt while you are at it, that is if you intend on replacing the pump. Better mark how the old belt was routed, others have had trouble.

I am going to replace the belt, and water pump.  I am hoping the image provided of the belt path through the pullys will help with reassembly.  It was pretty tough to even get the belt OFF, so I am assuming an even harder job of having to put it all back together.

I wanted to give others a tip: Since my screws were stripped, I called a local repair shop for replacements.  They wanted 7$ each for the Screw, 5/16 - 18 x .50 .  I went to my local hardware store - home depot and they had an inch long hardened steel replacement for about $1.  I wanted to find a 1/2 inch version so I found the identical part, in the highest quality hardened steel - at Fastenal.  Try this shop if you are in a similar situation.

I've attached an image of my water pump.  It looks pretty clear that the bearing or part that the motor turns is worn down to almost a circle shape when it should be almost rectangular.  It is also cracked.  I am crossing my fingers that this is the broken piece and my replacement will fix my lack of draining water at the end of the cycle!  Thanks ApplianceJunk!

Yeah you can clearly see the bearing has a crack in it

In this example we are using a Maytag model NAV5800 washer. If your Maytag or Amana washer has a service panel on the bottom front of the washer it should be the same as the one we used in this example.


Thanks for this tip. This beats the factory suggested procedure, i.e. removing the cabinet and working from the top down to roll the tub and base assembly out and upside down to access the parts. This does indeed acces all the parts, but it's a pain, if all you're doing is replacing a pump or a belt!

Please feel free to ask any question. :)

I've followed these directions and got stuck at removing the pump from the motor. I removed the 3 torx screws and then the pump just wouldn't let go.

My wife commented to me to "office space" it.. :)

I tried a lot of bad ideas.. but what eventually worked was sticking a crescent wrench between the pulley and the bottom of the pump and just prying the thing off. I'm really not sure what the right way to do this is.. The concern I had about the way I did it, of course, is bending the pulley itself..

Upon removing it, the inside of the bearing and the shaft going into it had a nice rusting to them..

Also, I think it's worth mentioning that it's tricky getting the belt off. I'm worried about getting it back on. For those who haven't done this before, there is a tensioner in the belt path and pushing on it significantly eases belt removal (ie: makes it possible). This may not be obvious to someone who hasn't replaced belts before. :)

If you mess up the pulley you will need another motor. I have sawed them pumps off with a hacksaw and smoothed up the shaft afterwards. If you beat on it with a hammer you will ruin the motor. You must cut it off. I soak it with rust buster.

The guide is in error - there is no need whatsoever to remove the big springs.  They are attached to the ring to which the motor is attached.  Take the 4 bolts off attaching the motor and it comes out through the springs w/o difficulty.  The ring stays put with the springs attached.
