Washing Machine Repair – Replacing the Motor with Pulley (Whirlpool Part # 21001950)

Hi! It’s Den from washer-repair.ca. we’re going to explain you how to change the motor and pulley on your washer and it’s a really easy job, all you are going to need is a putty knife, a 5/16ths nut driver and a ¼-inch nut driver, a small flat blade screwdriver, a pair of slip joint pliers and a 3/8ths socket and ratchet. Let me explain you how we do it. Now the first step in this repair will be to lift the main top and then remove the front panel, there is a couple of spring clips that are re-enabled four inches from either side that we need to release to lift the main top, so with the thin putty knife we will come in from the center till we feel an obstruction and then depress the spring with the putty knife and carefully lift the top and we want to position the washer so that we can either lean the main top against the wall or have somebody support it, while we are doing the Appliance repair downtown in Toronto.

harness off the motor, and

Next we’re going to remove two 5/16ths hex head screws that secure the top of the front panel to the cabinet. Now we’ll tilt the front panel away at the top and then we will disengage a couple of hooks that are attached to the base frame, and then we can remove the front panel and set it aside. Now to remove the motor it’s held in place with two 3/8ths bolts, one on the front and one on the rear, and we will need to remove this ground wire as well and it’s held in place with two ¼-inch screws that hold it both to the motor base frame and to the washer base frame.

So we’ll begin by taking that harness off and take note that the ¼-inch screw that secures the ground wire to the washer base is a self-tapping screw, and the one that secures it to the motor base frame is a machine screw.

Next we’re going to remove 3/8ths bolt at the front and then we’re going to rotate that motor forward. If you can’t get the motor forward enough to access that rear bolt you may need to tilt the washer at this point and roll the dry belt off of the motor pulley, and we’re just going to reach in behind and then we are going to locate that 3/8ths bolt it is identical to the one on the front, just pull that bolt out and set that aside.


Now we can lift that motor free of the base frame, again if it’s caught on the belt, we will need to roll the belt off of the pulley first, and then just pull it out far enough, we can access the two screws that secure the motor cover in place, and there are a 5/16ths screw, and simply lift the cover off, set that aside and now we take a flat blade screwdriver and we will unhook the locking tabs to the wire harness and then simply pull that wire harness off the motor, and then we can take the motor completely out of the washer base frame. Now to transfer the original motor base to the new motor, we will need to remove these two 3/8ths nuts and the sliders as well as the tension spring. Now the tension spring just take a pair of slip joint pliers and we are just going to disengage the bottom of it from the motor, pull it out and tilt sideways and then unhook it from the motor base and we will be reusing that, so I am just going to set this aside.

Next we will remove the 3/8ths nuts and we will set those aside and keep the sequence of the flat screw washer and rubber mount and the nylon slide all in order, we will just slide it out over the motor pulley, and we will remove the rest of that assembly and set that aside, and we will also remove the glide pad from the bottom of the motor, just pull it straight out of the motor housing, there is a rubber bush and so it’s fairly snug in there, and then we can discard the old motor. Now with a new motor we will start by putting in the slide, and you may have to moisten that rubber portion of that to make it fit into the opening, just a little bit of dish soap, it’s a good lubricant for that, and it will actually go in easier if you can remove the nylon slide first, then press the rubber mount in and your motor set there is a bulbous shape to that glide and then just force that in, and that part is installed. Next we will reassemble the nylon and rubber mounts with the bottom portions of them on, next we’ll install the actual motor mount, slide it around the pulley first and then carefully reassemble and make sure the nylon glide sit inside of the slotted openings, rubber mount next, flat washer. As the flat washer is in place, take the steel washer, set that flush on top of it, and reinstall the 3/8ths nut and then we will do the opposite side.

Again make sure that we center up that nylon portion, so that it sits in slide slot, next the rubber mount, flat steel washer and then the 3/8ths nut, tighten those securely, make sure that it pivots freely and then we are ready to reinstall the spring. So we will take the hook portion of the spring first, insert it through the opening in the top, rotate it around, just compress it enough till it snaps into both the notch on the motor base and the notch on top of the motor and now we are ready to reinstall the motor assembly into the washer. Now on reinstalling the motor we are first going to just tuck that harness out of the way enough that we can set the motor partially into position and we will reconnect wire harness, make sure that the locking tabs engage on both sides, and just pull it out far enough that we can get the cover on it, reinstall those 5/16ths hex head screws and now we will carefully set that motor down into the opening in the base and rotate it around, so that the holes line up for the mounting bolts and slide one in the front, and we will just start that bolt, and we can pivot that motor around enough and we will insert the bolt from the rear and now we’ll tighten the rear ones securely, rotate the motor around so that we can access the front one, we can snug that one off now. Now next we need to install the ground wire, so just pull it around beneath that motor cover and with the ¼-inch hex head machine thread screw, we will put that one in the motor base frame, and we need to make sure that that screw is tight and then we will install the one in the base, and that’s your self-tapping screw. Now we are ready to put the front panel back on and then we can turn the machine upside down and install the drive belt.

explain you

So just carefully lift it up and set the pulley down through the hole and install the bolt on the front, we won’t tighten this bolt completely and we will rotate the motor forward, and then locate the hole on the backside and you may have to pivot that motor base frame until you find the nut on the frame and then we can tighten that bolt. We will rotate the motor back into position, tighten the front bolt securely and then route the ground wire into position and we will install the machine screw to the motor base frame first, and then with the self-tapping screw we will secure the ground wire to the washer base, and now we can turn the machine around and access the back of it to replace the two remaining springs at the very back. Now to gain access to the rear springs we will need to remove the rear access panel, we find it easier to just pull the machine completely away from the wall, disconnect the fill hoses and the drain hose, it just makes it a little easier to work on, back panel was held in place with 5/16ths hex head screws, we are going to remove three across and the top and the two on the ends, and then we will just loosen the three on the bottom. We will set that panel aside and again we’ll put our protective gloves on and we are going to pull that tub towards the back and then with our locking pliers, grasp that spring firmly and then we’ll lift it free off the hook, tilt it over the base frame, discard the old springs, then we’ll apply a little bit of grease to the hook on those springs before we reinstall the new ones and verify that the openings on the top have grease on them as well and if not add some to the spring, and we will take our locking pliers, insert the spring into the base frame, make sure the end of the hook comes up through the frame and just stretch the spring enough to catch that hook, and do the same for the last one.

will be reusing that, so

Now we can reinstall the back panel and make sure that we engage all three slots on the bottom of that panel. Now we’re ready to reconnect the drain hose and the fill hose and put the washer back into position. Now to reinstall the front panel we want to make sure that we engage those slotted holes on the bottom of the front panel with the clips that are attached to the base frame. We also have a couple of locating pins one on each side that will have a nylon insert that slides over those, make sure those are both in position before we install the panel and then as you raise the panel into position, make sure that those pins line up with the appropriate hole and then hold it in position, and we will start the 5/16ths screws to secure it, and make sure both of those screws are tight, and also check there is two locating pins on the top of that front panel, that will engage two holes in the main top, there is also a rubber gasket that fits down over those pins, make sure those are both in position, and carefully lower the main top, line up those pins and then press the top into position so the spring clips catch, now that we have the rear access panel and the front panel and the top installed our repair is complete.

I told you it was an easy job, thanks for reading and good luck with your repair.
