3DWTW4840YW0 Whirlpool Washer - Instructions

Removed the agitator cap, then removed the plastic, spring loaded retaining part (needed a square head tool). Once out, the cog retainer came out, replaced all four cogs, and replaced in reverse. Easy as pie & took 10 minutes!!

Washer stopped agitating. I removed the clothes softener cup on top of the agitator by grasping and pulling up, inside the agitator I removed the inner plastic cap by grasping the 2 finger tabs and pulling up. There was a plastic retainer assembly with spring instead of the 7/16 nut referred to in other posts. I used a long 1/2" ratchet extension to remove the plastic retainer assembly, removed the top half of the agitator and replaced the cogs, then replaced the agitator, plastic retainer assembly with spring, snapped the plastic cap back on, and replace the clothes softener cup.

Pulled up and removed the fabric softner dispenser. Then I pulled up and removed the cap barrier to have access to the screw. Removed the screw and pulled up the cloths mover. Tunrned the cloths mover over to remove the bearing cam to remove the broken agitator cogs and replaced them with the new ones. I held the bearing cam with my right hand and held the cloths mover with my left hand turning it slowly with my left hand and lightly pushing down with my right hand until the cloths mover made contact with the grooves of the shaft and it sunk down on the shaft. Replaced the screw and washer then the cap barrier , next the fabric softner dispenser. Took 10 min. to complete the job. Now my washer runs like new ! Plus, I have a happy wife!

Removed the agitator assembly with a socket wrench and extension, replaced cogs, reinstalled assembly...took about 10 minutes because I dropped the assembly once, and had to reassemble it. An absolute "piece of cake."

Snap off softener dispenser. Pop off top of agitator with flat head screw driver. Use long handled socket ro remove agitator fastener. Lift off entire agitator assembly. Flip upside down on floor. Secure top section of agitator between feet and carefully unsnap but lifting upper portion. Look at placement of existing agitator cogs in upper section between feet. Remove cog retainer. Note position of cogs. Replace one cog at a time making sure they are repositioned the same way. Attach cog retainer. Place bottom portion of agitator in alignment and snap. Flip over and reinstall on washer center assembly. Place bolt and washer back into assembly and retighten. reattach cover and softener dispenser (if you have one). Done! Less than 15 minutes.

Repair was simple and quick. Started by removing softener cup and removed bolt holding part that housed dogs. Removed housing and slipped of hold down clamp and replaced the 4 dogs then reversed procedure all took about 8 mins

popped off the softener dispenser, pulled out seal over nut assembly, used socket wrench with extention to loosen and remove nut holding cog assembly.
slid holding ring off of the bottom (mine was black in color) pulled out old dog agitators put in new ones, reverse assembled the unit tightened it down, (be sure not to go too tight there is a rubber bushing under the nut) ran a small test load of laundry and it now works great!!!!

I popped the liquid detergent cap off of the top of the Agitator. I then removed the seal cap to expose the Agitator dog assembly and bolt. I removed the entire Agitator dog assembly and Agitator by removing the single 7/16? bolt. I pulled the old dogs out, put the new dogs in and reassembled the Agitator Assembly.

Works like new!!

Took the cap off the agitator, loosened the nut with a wrench, and pulled the agitator out. The agitator pulled apart easily, revealing the piece containing the dog ears, which were clearly worn out. Simply replaced the dog ears and reinstalled the agitator. Piece of cake!

The repair was very easy, I took the top cap off the agitator and removed the recess bolt and pulled the agitator out of the washing machine,put the agitator on the floor and put my feet on the sides of the agitator and pulled the top haft apart,replaced the agitator directional cogs put back together work great

With the help of a You Tube video, which was watched first, then when the parts were delivered, the video was watched again, then we played the video back and paused it after each section was done so we could make sure we were doing the repair correct. The one thing I will mention that the video doesn't mention to do is, before taking the agitator out of the washer, put a mark somewhere on the agitator to tell you which end is the top. Just remember that the top( cap ) will be off, so that will not work. Otherwise it was a good, easy fix

Could be done in place, but it's easier to pull the full agitator assembly out first, and work at a table. Remove the fabric softener dispenser, then the plastic cap below (with rubber o-ring)- both pull out by hand. Reverse the now visible bolt with an extended 7/16" socket and pull the cog housing up and out, gripping with gentle pressure with pliers ( locking plastic tabs make this piece impossible to remove by hand). Once the housing is removed it's easy to separate the two halves with your fingernails and replace the cogs. I was able to reassemble everything and push it back down into the drum in about two minutes. Piece of cake- I highly recommend anyone with a tool box do this himself.

got the parts from parts select and got the machine repaired quickly
what a savings
repair man would have been over 100 dollars
the shipping was more than the parts but I saved greatly with no repairman
love your site and the great savings
i really loved my washing machine and hating to lose it
was so satisfied that I could save it after all these years
thanks

First I popped off the very top cap of the agitator. I then used a socket extension to access the mounting bolt in the interior of the agitator. Once the bolt was loose i pulled the agitator off and dropped out the middle piece. With this out i switched the 4 cogs with the old. I then held the agitator assembly upside down and placed the middle piece back in. The most difficult part was aligning the agitator back onto the bottom part. Screw it back in place and pop the top back on.

To replace the dogs that cause the ratcheting motion:

I removed the softener cup by pulling straight up. (You've probably found, as I have, that the softener cup and the bleach dispensers are problematic: the softener cup must be cleaned with every use or the old softener liquid turns to glue, and the bleach dispenser mechanism plugs and distributes bleach onto your next load, ruining entire loads of clothes.)

Then I lifted the cap covering the retaining bolt by inserting a screwdriver alongside in the square holes provided, loosening it, and lifting it out.

Then I used a socket and a very long extension to remove the retaining bolt. I lifted the agitator straight up.

The next step can be a problem: I survived it (though I did strain my back). What's required, as you can see by reading the preceding letters, is to lift sharply on the upper agitator while holding the lower agitator with your bare feet or some soft shoes. What this does, at least on my model, is to break off the tabs that are fused together over the ratcheting-dogs, which are the focus of the repair. (These tabs hold the upper and lower assemblies together, moving the dogs assembly with the lower agitator.) In my case, one of the tabs broke off a half inch below the top, but that wasn't catastrophic and I didn't lose the rest of them, so when I reassembled the two halves still snapped back together.

One problem was that when I jerked the two assemblies apart, the parts of the dogs assembly went flying. Everyone had said to make sure everything went back the same way it came apart--for me there was no way to tell what that way was, but common sense tells you which way to reinstall the new dogs; they have to catch every stroke.

To reassemble, position the dogs with the retainer cup inverted. Then hold them upside down while sliding the upper agitator down over them. This holds them in place. When sliding the upper agitator down onto the lower, make sure the slots line up and use a smooth even pressure. Snap the two halves together, bolt the agitator back into the machine, replace the cap with the large o-ring (make sure you clean and/or replace the o-ing), and reinstall the softener cup.

Et, voila! You're back in business.
