How to Install Main Bearing 725P3 in an Alliance Washer
Before You Start
A main bearing repair needs patience. You may need to remove panels, loosen drive parts, and support heavy washer parts. Rushing can bend brackets, strip fasteners, or damage seals.
Start with a clean work area. Move baskets, rugs, and storage items away from the washer. Keep the floor dry. Good lighting matters because many washer parts sit low or behind panels.
Unplug the washer before touching any internal part. Shut off the water supply if you need to move the washer or open areas near hoses. Washer cabinets can have sharp edges, so wear work gloves.
For general appliance safety habits, you can review federal home energy and appliance use guidance from Energy Saver laundry tips. That source does not replace your washer’s service details, but it supports safe, efficient washer use.
Tools and Supplies You May Need
Use the correct tools for your washer’s fasteners. Do not force a tool that does not fit.
Common tools include:
- Work gloves
- Safety glasses
- Nut driver set
- Socket set
- Screwdriver set
- Adjustable wrench
- Pliers
- Towels
- Small container for screws
- Flashlight
- Phone camera for reference photos
You may also need a soft block or support if a heavy assembly must rest during the repair. Avoid placing washer parts on a bare concrete floor. Metal parts can scratch, bend, or collect grit.
Keep Main Bearing 725P3 in its package until you are ready to compare and install it. Dirt on bearing surfaces can shorten service life.
Confirm the Part and Washer Model
Check the washer model tag before you begin. Do not rely on the look of the machine alone. Many washers share cabinet shapes but use different internal parts.
This article uses these supplied compatible models:
| Alliance washer model | Part used in this guide |
|---|---|
| AWN311SP111TW01 | Main Bearing 725P3 |
| AWN402PP111TW01 | Main Bearing 725P3 |
| AWN432SP113TW01 | Main Bearing 725P3 |

If your model number is not listed here, stop and verify the correct part before ordering or installing. Never guess on a bearing. A close-looking part can still fit wrong.
Look for the model tag around the washer opening, rear panel, or cabinet area. The exact tag location can vary by washer design. Write the full model number down, including every letter and number.
How to Install Main Bearing 725P3: Repair Overview
A washer main bearing sits in the drive and tub support area. Its job is to let moving parts turn smoothly while holding the load in position. When the bearing wears, the washer may not work properly.
This repair usually follows this order:
- Disconnect power and prepare the washer.
- Remove the needed cabinet or access panels.
- Document belt, pulley, and fastener positions.
- Remove parts blocking the bearing area.
- Take out the worn bearing.
- Clean the mounting area.
- Install Main Bearing 725P3.
- Reassemble the washer.
- Run a controlled test cycle.
Your washer design may not match every detail in the same order. Use the steps as a careful repair path, not a forceful teardown script.
Symptoms That Point Toward a Main Bearing Problem
The supplied symptom is broad: washer not working properly. That can mean many things. A bearing is only one possible cause.
A worn main bearing may show up as:
- Rough movement during spin
- Grinding, rumbling, or scraping sounds
- Extra tub movement
- A washer that struggles under load
- Wear near drive parts
- Leaks near related seals, if the seal area has failed
Do not replace the bearing based on sound alone. Inspect nearby parts while the washer is open. Belts, pulleys, mounts, and loose hardware can cause similar problems.
Run this quick check before teardown:
| What you notice | What it may mean | What to check first |
|---|---|---|
| Rough spin sound | Bearing wear or drive wear | Bearing area, belt, pulley |
| Washer shakes hard | Load balance or support issue | Leveling feet, suspension, tub movement |
| Washer will not move well | Drive restriction | Belt path, pulley, bearing |
| Noise changes with speed | Rotating part issue | Bearing, pulley, motor drive area |
| Water signs near bearing area | Seal or tub issue | Related seals and mounting surfaces |
Decision Check: Should You Keep Going?
Before you remove the bearing, decide if this repair still makes sense.
Use this quick decision matrix:
| Situation | Best next move |
|---|---|
| Model matches the supplied list | Continue with part verification |
| Model does not match | Stop and confirm the correct part |
| Bearing area looks clean and accessible | Continue carefully |
| Major rust surrounds the bearing area | Inspect deeper before installing |
| Tub or support parts look cracked | Do not install until damaged parts are addressed |
| Fasteners are badly stripped | Plan extraction before teardown |
| Washer has several unrelated failures | Compare repair effort with washer condition |
A new bearing cannot fix a cracked tub, damaged support, or wrong drive alignment. Installing it into a damaged area wastes time and may damage the new part.
Step 1: Disconnect Power and Water
Unplug the washer from the wall outlet. Do not work on a plugged-in washer. Turning a control off does not make the cabinet safe to service.
Shut off hot and cold water valves if you need to move the washer. If you disconnect hoses, place towels under them first. Some water can remain in the lines.
Pull the washer forward only as far as needed. Do not stretch hoses or the drain line. If the drain hose is short, release it from its holder before moving the washer farther.
Keep the plug visible while you work. That helps prevent someone from plugging the washer back in by mistake.
Step 2: Take Reference Photos
Take clear photos before removing parts. A phone camera can save you during reassembly.
Photograph:
- Rear or front access area
- Belt routing
- Pulley position
- Wire routing near the work area
- Bracket positions
- Fastener locations
- Any washers, spacers, or clips
Take one wide photo and several close photos. Shadows can hide key details, so use a flashlight if needed.
Place screws from each section in separate piles or small containers. Label them if several sizes look close. Mixing fasteners can cause rattles, stripped holes, or panel fit problems.
Step 3: Open the Washer Cabinet
Remove the access panel or cabinet section needed to reach the drive and bearing area. The exact panel depends on the washer layout.
Work slowly around painted panels. Sheet metal can flex if you pry too hard. If a panel will not release, look for a hidden screw or clip before pulling harder.
Set panels aside where they will not get stepped on. Keep screws with the panel they came from.
If you see wires, do not pull on them. Move only what blocks safe access. Disconnect a wire harness only if needed, and photograph it first.
Step 4: Inspect Before Removing the Bearing
Once the bearing area is visible, stop and inspect. A careful look now can prevent a failed repair later.
Check for:
- Rust trails
- Metal dust
- Loose mounting hardware
- Worn belt material
- Cracked brackets
- Damaged pulley surfaces
- Signs of water near the bearing area
- Bent or rubbed parts
A bearing often fails because another part allowed movement, water, or misalignment. If the surrounding parts look damaged, replacing only the bearing may not solve the washer problem.
Spin related parts by hand if the design allows safe movement. Feel for grinding, wobble, or tight spots. Keep fingers away from pinch points.
Step 5: Remove Drive Parts Blocking Access
Remove any belt, pulley, bracket, or cover that blocks the bearing area. Keep the removal order clear.
Do not bend a belt backward or stretch it with a sharp tool. If a pulley must come off, support it evenly. Avoid hammering unless the service method allows it. Heavy impact can damage shafts and mounts.
Mark positions if parts can rotate or align more than one way. A paint marker or photo can help. Use light marks only where they will not affect movement.
If a fastener is stuck, apply steady pressure with the correct tool. Stop if the head starts to round. A damaged fastener can turn a medium repair into a much harder job.
Step 6: Remove the Worn Main Bearing
Remove the old main bearing from its mounting area. Keep the bearing straight as it comes out. Twisting or prying against soft surfaces can scar the seat.
If the bearing resists, check for a retaining part you missed. Do not assume it is only stuck. Some assemblies use clips, shoulders, or tight-fitting parts that must release in order.
Avoid driving against nearby seals or support surfaces. Those areas need to stay smooth. A gouge can cause noise, leaks, or early bearing failure.
Once removed, compare the old bearing to Main Bearing 725P3. Match the general form and seating features. Do not install a part that looks damaged, dirty, or different from the needed design.
Step 7: Clean the Bearing Seat
Clean the bearing seat before installing the new bearing. Dirt under the bearing can make it sit crooked.
Use a clean towel to remove loose grit, old residue, and metal dust. Do not use harsh methods that scratch the mounting surface.
Inspect the seat for:
- Burrs
- Deep scoring
- Rust pits
- Cracks
- Out-of-round wear
- Loose mounting points
A clean seat should let the bearing sit square. If the area looks damaged, stop and decide whether more parts need service. A bearing installed into a bad seat may fail fast.
Step 8: Install Main Bearing 725P3
Position Main Bearing 725P3 in the bearing seat. Keep it square to the opening. Press or seat it evenly using the proper contact area.
Do not press on parts that should not carry installation force. Do not hit the bearing directly with a steel hammer. Direct impact can damage the bearing before the washer ever runs.
Work in small, even movements. If the bearing starts to cock sideways, stop and correct it. A crooked bearing can bind, make noise, or damage the washer support area.
Confirm the bearing sits fully and evenly. Compare its position to your photos and the old bearing’s installed depth if visible. Reinstall any retaining parts you removed.
Step 9: Reinstall Drive Parts
Reinstall the parts that blocked access. Use your photos to restore the correct routing and positions.
Check that:
- The belt follows the same path
- Pulleys sit straight
- Brackets return to their original locations
- Wires stay away from moving parts
- Fasteners are snug
- No tool remains inside the cabinet
Do not overtighten small fasteners. Tighten them firmly with hand tools. If a screw spins without tightening, stop and inspect the hole or clip.
Rotate moving parts by hand if safe. The movement should feel smoother than before. A small amount of normal resistance may remain, but grinding or binding is not okay.
Step 10: Reinstall Panels
Reinstall the washer panels before testing a full cycle. Panels help protect you from moving parts. They also support the cabinet and reduce vibration.
Line up panel tabs before tightening screws. If a panel does not sit flat, something may be trapped behind it.
Check the washer’s position after pushing it back. Keep hoses from kinking. Make sure the drain hose still sits secure in its drain point.
Plug the washer back in only after every panel and guard is back in place.
Step 11: Run a Controlled Test
Start with a short test, not a full heavy load. Listen closely during fill, wash, drain, and spin.
Watch for:
- New grinding sounds
- Belt squeal
- Cabinet rubbing
- Water leaks
- Burning smell
- Strong vibration
- Failure to spin
Stop the washer if you hear a harsh sound or see water. Unplug it before opening anything again.
If the washer runs smoothly, try a small laundry load next. Do not test with a large load first. A small load gives you a safer way to confirm the repair.
Common Mistakes to Avoid
Main bearing repairs fail when small details get ignored.
Avoid these mistakes:
| Mistake | Why it matters |
|---|---|
| Skipping model verification | The wrong part may not fit |
| Working with power connected | Shock and injury risk increase |
| Forgetting reference photos | Reassembly becomes guesswork |
| Forcing stuck parts | Shafts, brackets, or panels can bend |
| Installing into a dirty seat | Bearing alignment can fail |
| Ignoring rust or cracks | The new bearing may wear fast |
| Testing with a large load first | New problems become harder to control |
The most expensive mistake is forcing parts. If something will not move, find out why before using more pressure.
When the Washer Still Is Not Working Properly
A new bearing may not fix every problem. If the washer still does not work properly after installation, inspect related systems.
Check these areas:
- Belt condition
- Pulley alignment
- Motor drive area
- Lid or control function
- Water fill and drain path
- Tub support parts
- Leveling feet
- Cabinet contact points
Noise after repair often means a rotating part is misaligned or rubbing. Vibration may point to leveling, load balance, or support wear. No movement may point toward a control, switch, motor, or drive issue.
Do not keep running a washer that sounds worse after repair. Shut it down and recheck the work.
Maintenance After Bearing Replacement
A bearing lasts longer when the washer runs level and does not carry abuse.
Use these habits:
- Keep the washer level.
- Do not overload the tub.
- Balance heavy items with similar items.
- Clean spills near the cabinet.
- Fix leaks quickly.
- Listen for new noises early.
- Keep the washer area dry.
A washer that walks across the floor places extra stress on moving parts. Leveling and load control help protect the new bearing.
