2006 Ford Explorer 4.0 4.6 V6 Harmonic Balancer Replacement

Helping a friend out, the belt originally came off. After further inspection the harmonic balancer had failed and needed to be replaced. Not uncommon with the 4L Fords. A good sign is the belt sequels and jumps around, along with the balancer looking chewed up. Thanks for watching!

[@o1onewbeginningso1o]

the trick with the belt to tighten the harmonic balancer is life saving, wow thanks alot man!

[@dimitrin101]

The belt trick was a huge time saver! Thanks for sharing!

[@josephb7296]

Thanks. This was exactly what I needed. It got the explorer back on the road.

[@alexcook53]

you saved me from such a huge headache, thanks a bunch!

[@scottmckenzie1765]

i found two things that helped a lot doing the pulley on my 4.0 mustang. the GM extension tool fit perfectly inside to push the pulley off with the puller. Second a fan clutch spanner tool fit in the balancer puller holes to hold it tight getting the center bolt off and torquing it back on. way easier than finding a way to get a belt on perfectly

[@HHT504]

awesome. i have been suffering for a while trying to figure out which pulley needed change. i had different guys telling me different things. now i know for sure.

[@looking4Hisreturn]

Went to Harbor Freight for the same impact wrench. It worked perfectly! Called dealership for bolt. Was told 10 dollars but he let me have for a little over 7 when i got there.

[@keithstanley7313]

Great video. I thought my 4.0L 2007 Mustang with 118,000 miles would be similar, but it wasn't. So, in the spirit of helping others: O'Reilly does sell a balancer from Dayco that is perfect match. The crankshaft bolt is right hand threaded. The bolts in the universal puller from O'Reilly and Autozone are too short. You will need a couple M8x1.25x90 bolts. The center hole in the balancer is too small for the universal press installers. M12x1.5 threaded rod would be ideal to press the balancer on the cranksaft, but threaded rod that size is hard to find. I did find a M12x1.5x130mm bolt and with a small section of 1 in square iron was able to "connect" the 130mm bolt two a second bolt to fashion a press tool. I did install a new Ford bolt as recommended by Ford and torqued it as described in the video.

[@1975martinez2010]

Thank you for the video I changed this part in my Ford Explorer 2004 and man let me tel you what a pain to change it was all rusty ,but I got it done , not a easy job, if you don't have the tools you best Choice is to bring it to a mechanic

[@MrPoppadog1955]

unbelievable this is exactly the same problem i had i only you tube to see what size the balencer bolt was very informative. mine looked excatly the same condition it screwed up my crankshaft sensor wouldn't start. thanks for the video

[@MrPoppadog1955]

got the bolt out but having a hell of a time getting the balancer off.

[@unclelarryboy1608]

Thanks man. I'm changing an alternator. I just needed to see how to do the serpentine belt.

[@carlovincetti1352]

Good idea on using that belt to hold the balancer:)

[@alfredwalker1580]

Thanks this help alot I did not know what was going on, I replaced the alternator, the belt ,pulleys 3 times before taken it to pep boys , cost $509 paid that much in belts, alternators and pulleys

[@jdbrown668]

After finally (3 days) getting the bolt loose now, cannot get the pulley off. Have tried 2 different styles of pulley pullers with NO success....any suggestions? I need this done asap!

[@andrewlookner4593]

you are an expert at taking a video that should be about 5 minutes long and turning it into a 25 minute video filled with excessive babbling like going to harbor freight. Thank god someone invented a fast forward button or i would have lost my mind watching this! thanks for the video.

[@anatoly8130]

cool, you're a great master!

[@bryceyoda]

I just did this this job ended up being a bit of a nightmare. The puller bolts were to short and needed 8mmx1.25x90mm or 100mm long. After installing the dorman harmonic balancer I started getting misfire codes P0300 P0303 p0304. I changed out the crank sensor and spark plugs. I ended up pulling the balancer back off and found that the pickup teeth for the sensor were bent on the new balancer. Make sure to check your new one before install. I just wanted to share this info for others.

[@NaranyaR]

The Harmonic balancer in your video split in 2. The metal bottom was supposed to be at the top where the rubber was but it had separated. The only reason the rubber part had teeth is because someone installed the belt on it and ran it with the belt on the rubber.

[@dimitrin101]

yep

[@coreycantwell2019]

Mine split like this as well. The belt gradually crawled over the edge of the pulley as it drifted, and the belt just landed on the rubber part. The thing did it all by itself.

[@chrisbauer4316]

Not totally sure if that is correct because mine looks like that too

[@TheMarshalleseboy]

I had the same problem with my 07 mustang v6 and what caused the noise was that the thermostat housing was leaking, Changed it and the noise went away. BUT i did notice that the harmonic balancer was wobbling a little bit. I ignored it and eventually my car cranked but did not start. The crankshaft position sensor sat next the harmonic balancer and was shredded because the balancer was so out of place and i cannot put the new sensor in. Im installing the balancer next week along with a new belt .

[@jessymcconnell2463]

say you dont have an impact to bust the bolt loose, how or what can i use to steady the balancer so i can break the center bolt?

[@katil5413]

what did you do to keep the flywheel from moving?

[@angelquinn7648]

Ok so you were able to use the pulley set to get the balancer off my friend has the same year and model and he cant get the balancer off i was wondering what the length and thread of the bolts you used in the tool were to try and help my friend get the balancer off without damaging it

[@felipevalles8041]

Did you change the Crank seal as well? My Mountaineer’s lights and courtesy lights are flickering,alternator is good so is the battery but I can see that the serpentine belt tensioner is weak ,do you guys think that maybe that is the problem? Thanks

[@ErichMoozee28Moosreiner]

What size compressor you got ? My air impact won't touch it . Thought maybe my 30 gallon sears oilless compressor wasn't big enough. It's only got 6.4 cfm @ 90 pounds .

[@miguelchamale675]

am working on my 2007 ford explorer and the harmonic balancer doesnt what to come out what do u suggest i do

[@conqno]

thanks what others think it's a waste of time to explain it point by point it actually helps ppl like me that doesn't know as much what's wrong with their truck. this helped alot!! by the way i have the ford explorer 05 is it the same part of will the part number change due to different year?

[@gerardoortiz577]

Thanks for the info how much does this work go for with a mechanic...

[@billcoley8520]

I wonder if you can use a chain wrench to hold it tight so you can torque the bold. I’m not sure I understand the 85 degree thing.

[@babyboyCJ2007]

Hi Tex I had changed my crank pulley at the dealership and once they did that truck was perfect UNTIL 20km later the truck wouldn't go past the 1500rpm and die, start it up beautiful idle bad rev 1500rpm and dies again, what do you think it is? thank you in advance.

[@ravvaktheannihilator69]

I changed my harmonic balancer on my 2004 Ford Ranger 4.0 SOHC now it runs terrible and is throwing a code. I torqued the bolt as it should be and did everything right. It was a pain to get off but it went on with no problems. All I did was take the fan and rad out to get enough room for my puller and I got the part from NAPA for $140 and it looks the same as the one on here. Only thing I think it could be is if I didn't seat it all the way down onto the block because the press I have won't work on my truck. So all I did was run it down with the crank bolt.

[@jimmynomad8793]

I wish you shared the tools needed to remove the fan clutch.. I have all the other parts and spend an 2 hours trying to pry the fan out, with no success..

[@juankarloz4486]

Dude. Never listen to the detractors in the comments. You provide a great service. Be useful.

[@Smash_That_Like_Button]

how does the sensor that is around the fan bolt come off?

[@jaimie2024]

The fan nut is not reverse thread it is right hand thread regular conventional thread and so is the balancer bolt.

[@derekvenable]

thank you sir!!

[@Smash_That_Like_Button]

did you have any trouble taking the sensor that is on the fan off?

[@lyrad14494]

jd brown , once you have removed the crankshaft (harmonic balancer) bolt make sure the washer is removed as well. Otherwise you will not be able to remove the harmonic balancer .

[@nobodyspecial3325]

nice video

[@paulkorkames7277]

it's a standard right hand thread

[@marvinmarroquin8736]

How many pounds of torque require the center bolt on serpentine bolt??

[@lemmuelpanganiban]

It happened on my 2007 explorer with 48000 kms only, one time when i was driving in the city around 30-50kph and suddenly felt something pop out and the belt start squealing and also felt a bit hard on my steering. I tried not to get panick and parked the car on the side of the road and turn off the engine. I went down from the car and inspected the engine, I saw that pulley already hanging on the lower radiator hose and almost fell on the ground. Luckily the car was still under warranty so I called Ford, they towed the car to their garage and repair it. Got my car back after a week.. and so far til now it is all good at 130000 kms.

[@LynxStarAuto]

Common problem on early 4.0's. They redesigned it, and the new pulley is more reliable.

[@Poeticalt911]

What's a reasonable amount to replace something like this?

[@robertrosenberg6638]

I cant visualize how to wrap the belt around the crank as a makeshift strap wrench. Does anyone have a link showing the method. It looks in this video like the belt is folded in half then wrapped around the balancer, but I cant figure it out in my head.

[@danielaguilar7526]

Did you ever find out how?

[@Fortuna_716]

So howd you get that key out of there?

[@TheOliverFamvlog]

how you lock it with crowbar

[@cybergimp]

any word on the toner ring?

[@DuckOnQuackk]

My 2008 Ford explorer 4.0 was thrown off 2 serpentine belts in the last week, the only thing I could find was the that the harmonic balancer pulley does not free spin, could be throwing the belt, can these seize and mean it's time for a replacement? Thanks

[@Youngstone-dr8xq]

It's not supposed to free spin make sure all the little grooves on all the pulleys that the belt ride on are clean and there's no built up rubber of greese or crud stuck in the grooves thats keeping the belt from rideing all the way down where its supposed to i ruined a couple belt from that problem in the past

[@DonaldRogersBaldEagle]

make sure you do not rotate the Shaft after removing the Woodruff Key as it also controls the timing chain sprocket. You can damage the valves if the pistons push up against them.

[@LiilTyweezy]

No you won't because the chain is still intact and synced with everything else so you are wrong actually

[@sandyplesky7646]

what if you don't have a torque wrench?

[@Cheator40]

Cool.

[@matthewwyngaarde2836]

@TheTexasCoder Where are you located??

[@billcoley8520]

Boy boy I found a exact problem that my explorer is doing including that squealing. But wait a second. Your balancer has 2 set of groves for the belt to ride in. My Ford Explorer only has 1 set of groves for my belt to ride in. Why is that? I’m talking about the one on the truck your going to fix

[@mikecwb12]

I replaced my 05 ranger 4.0 v6 with a Dorman HB and now my truck does not start up. Before replacing the broken harmonic balancer (looked the same as the one you are replacing) the truck was starting perfectly. Replaced belt, and crank sensor as well. any suggestions will be much appreciated

[@mikecwb12]

update: The dorman HB was not recognized by the crank sensor. I bought the oem from the dealership, the truck start up!

[@napochulo]

mikecwb12 Due to your post I went with a Precision Parts Powerbond OEM - Harmonic Balancer from Oreilly's and it worked great (advance auto parts sells Dorman). The Precision is about 180$ cheaper then Ford OEM balancer too. Thanks.

[@recklessgamerj8683]

having this problem as well.. just replaced with a dorman and wont start up. what a pain to do it twice.

[@stevenchapman7245]

Did you leave the old woodruff key in there? Ive been fighting it for about 2 hours and cant get it out of there.

[@jm2three]

Did u ever find the wood ruff key

[@JuanRamos-ce2lu]

Alguien sabe como se llama lo que va en las mangueras de calefacción x.el lado dé a bajo d

[@napochulo]

Not trying to troll your videow but none of the universal harmonic balancer tools from the local auto parts stores work. The removal bolts are to short and they look just like the one in this video so interested in seeing how he pulled this off. After rigging mine I finally got it off . FYI number 2 is none of the local harmanonic balancer installer tools work on newer explorers. After being down for 2 days I ended up tapping the new one in far enough to use the old crank shaft bolt to finish seating. I then used my new bolt to torque to specs as he did in this video. It was a risky move but was desperate at this point. Your using the serpentine belt to stop engine from turning worked great but started squealing a few days later. I ended up stretching it so bought a new one and she's purring now.

[@Timetotinker]

very nice..........tony

[@virgilbryant2844]

my 2005 explorer i put on a tensioner on now its not runnig

[@jacobanderson63]

Just to let everyone know itIS NOT A LEFT HAND THREADED BOLT!! i broke my bolt off thinking it was left handed while watching this video and I looked closely at the bolt in video and its STANDARD THREADED also. It cost me several days traveling to a different city where car broke down to fix the broken BROKEN STANDARD BOLT i had been tightening the crap out of til it broke.😡

[@chadpatterson5376]

DO NOT take the key out of the crank shaft unless it is damaged unless you want a lot of extra work , watch 1A auto video it will help a lot better

[@michaelbq7614]

Do u have the link to the video

[@philhamilton1452]

DeWalt391 elec won't bust the pulley bolt loose;any suggestions??

[@lancey1053]

i used a rubber strap wrench to lock the pulley, and a 18'' breaker bar. believe or not.

[@alfonsoramos5597]

Same problem. The serpentine belt on my girlfriend's 2007 4.0 v6 mustang is sqeaking like hell when it starts. It kinds quiets down a little bit after she runs it but not completely. I changed the belt and it quieted down but it started up again. I was thinking of replacing the crankshaft pulley. I ruled out all the other rotating pulleys. What should I do? Oh belt spray doesn't help either. It's really loud. Fords suck! This is ford's way of making money after the sale.

[@lynngatlin4469]

What keeps the motor from turning when using the puller.

[@robw2326]

Had this happen to my 2005 Explorer that I bought brand new...car only had 60k on it when it happened. Shameful. Vehicle cut off on me at 65mph suddenly..harmonic balancer had literally blown into two pieces. Total piece of shit engineering.

[@sandyplesky7646]

we have been fighting this thing for 12 hours help

[@alfonsoramos5597]

How come ford made the balancer so cheap like that. the one on my girlfriends mustang looks like that too. Obviously it's so that ford can make $$ after the sale. What happened to quality like the old days.

[@billypunte]

I bet the belts dont line up

[@johnmccay6691]

sure looks like RH threads to me

[@jacobanderson63]

It is right handed threads and while watching this video I broke my bolt off trying to loosen it "LEFT HANDED"😡 costed me days of work driving to a different city than I live where it broke down to put a STANDARD bolt back. And you can tell in the video his is standard too😡😡

[@lancey1053]

i shredded a new belt only to find the harmonic balancer faulty. To fix normal squeals i use baby powder.Fords are crap . All rubber components perish.

[@coffeebotography]

My hb wore out and destroyed a sensor. $510 repair

[@davidwright792]

Well well well I’ll leave a story for you!! My girlfriend thinks that I can’t do this “take it to a mechanic” she says well she doesn’t know the power of a man 🚬 she doesn’t get the code! Work on it till I honestly can’t get it! Then I blame your fucking video! Sound good I don’t want to hear told you so!!!

[@JoseDiaz-lf6yy]

Well I messed mine up

[@andrewlookner4593]

why would you pull the crank key? that's totally unnecessary, leave it alone!

[@jeffreykellerman9320]

The harmonic balancer bolt should not be reused, because it's a TTY fastener. Need to go to the Dealer for a new one.
