3LWTW4840YW0 Whirlpool Washer - Instructions

The dogs (directional cogs) cause the upper portion of the agitator to turn in one direction only. The clothes don't get clean unless this happens.

The material the dogs are made of wears out in a few months of use.

I buy 4 packages of them at once, every few years.

Pull off the inner cap, unscrew the bolt, remove the old cogs, put in the new ones, reverse the disassembly process and away we go.

Removed fabric softener dispenser. Inserted screwdriver into slot on side of cover that is on agitator and pried off. Used socket extension to unscrew bolt inside agitator. Lifted out and slid off plastic ring holding agitator cogs . Replaced cogs in the same direction they came out. Since these instructions were here on site at the time I ordered the parts, it made the job very simple and fast...the order came very fast too.

basically pop off the top spindle cover, reach in and pull off the water cap from the agitator cog cover, unscrew the bolt holding the cog holder and pull the agittator assembly up and off the machine. Remove the piece holding the gogs in place and replace cogs making sure to put them back in the same direction as they came out. Turn the agitator upside down and stick the piece holding the cogs in and snap it in. Replace all components in reverse order they were removed, and there you are. Works great.

Followed instructions on website video.

I noticed the agitator didn't "lock up" in one direction to properly agitate the load (which in turn "agitated" my girlfriend. I took the agitator apart to find the dog ears were worn. I ordered some new ones at a cost of about $12 delivered fed-ex and had the new dog ears installed in about 15 minutes saving me a bag of money from the repair man.

I was sent the wrong part , when I questioned them said they did not have it so was directed to Whirlpool and they are making it and I might get it in May

Popped off top of softener cup. Pulled out screen. Used nutdriver to back out the only bolt holding the agitator on. Pulled it off popped out plastic "gears" and popped new ones in. Put back in reverse order. Done in 5 minutes....worked perfectly! Easy!!! Thanks !!

Removed the fabric cone from center of agitator pop out the plastic cover inside, remove bolt in center pull on agitator, remove cam holder and replace cams.
repeat process to re assemble

I also ordered a new agitator repair kit which had almost everything. I noticed that I the kit had shorted 3 of the 4 cogs. Once the missing parts were received I removed the agitator bolt from the middle of the agitiator with a rachet and socket. Amazingly, I read the instructions and followed them accordingly. I pulled removed the agitator and removed the dogs/cogs and placed the new one in the new dogs *Making "dog gone" (pun intended) sure they were facing the correct way, by comparing them to the instructions. I carefully seated them as per the illustrations on the instructions and replaced the center bolt in. placed the cap on top and started the washer. Then I had my cup of coffee. By the way..I'm a grandmother, so if I can do it.............!

1. Lift the softener dispenser up and out
2. Lift up the plastic cap underneath
3. See bolt...use ratchet with extension to loosen and remove bolt
4. Remove whole agitator by simply lifting it up
5. Place agitator on floor and separate top from bottom agitator by simply pulling apart
6. See 4 plastic cogs that spin the agitator. Like mine they are probably completely worn/stripped.
7. Replace old 4-cog set with a new 4-cog set. They are small and inexpensive parts! I did this and our machine is working just great!

This also gave me a chance to clean the agitator thoroughly!

After removing the pressed in cap inside the agitator i removed it from the machine with a socket wrench. Then it did not take long to figure out that the two peices snapped apart. then one look at the cogs (referred to as dog ears) i knew they where stripped and where the problem. Icanceled the service call and order the parts myself from this site. So it was very easy and i'm not sure how much money i saved but the bragging rights went along way with the wife, Thanks.

Using the IPB I removed the upper assembly to gain access to the cogs. Turned the assembly over and incerted the new parts and reassembled the pieces in reverse order.

FIRST I printed the directions from an online DIY stie, then removed a single bolt from the center of the agitator. I dismantled the agitator, replaced the dogs, and used to printed page to help me reassemble the agitator. I then replaced the bolt. It's VERY easy, but you need the pictures to be sure you've put everything back in the correct place.

I took a socket and removed the agitator bolt and cover which exposed the cogs. I cold see the cogs were stripped. I changed them and everything works fine.

first remove the cap on agitator(softner),then pull out inside cap (small cover inside),loose bolt in center (you need a 7/16 socket with a long extension) after that pull up the whole assamble out of the washer tub,hold bottom part and pull up agitator ,turn up side down to take out the cogs and holder, replace with new ones and go back on the instructions.
