How to change an alternator pulley
HTML-код
- Опубликовано: 1 окт 2024
- Over the years I have seen people struggle for hours, even days to remove an alternator pulley. There are a couple of ways to do it without damaging any parts or yourself. However, the one that I find the easiest is to use an impact wrench. As with any power tool There is some DANGER involved with doing it this way since your hands are very involved, you must be very careful! This will also give you an excuse to go buy yourself an impact wrench, electric or otherwise. As always learn a new skill or practice the ones you already have, either way turn them into craftsmanship. You never know how far they will take you.

Straight to the point with no rubber gloves, The real deal. Thanks for not wasting our time
Why can't other videos be this simple, 3 years and this man's videos is still the most straightforward explanation..thanks
Thank you!
That’s a powerful comment right there.
In case you missed the graphic, YOU REALLY SHOULD BE WEARING GLOVES FOR THIS", unless you want your hand to look like a serpentine belt.
This made me laugh😂😂
I just did mine without gloves. I'm a mechanic so abusing my hands is just another day.
I actually wouldn’t use gloves, gloves would make it slip, without em you can actually hold it still
The only time the internet and RUclips is worthwhile is when I find a good, straight to the point video. Haven’t had to change a pulley yet and glad I watched this before I did. Impact, socket, good to go except I had to jam a screw driver in it because the nut was not breaking. Thanks. Good stuff 👍
Glad I could help
Thanks for watching
Late 2022 and saw your video.
Yes, I put on light gloves, and I also used my little 20 volt DeWalt impact driver…
…so simple a 68 year old senior can do it.
Thank you.

I cannot thank you enough for this video. I was struggling with an alternator pulley from a diesel semi truck. This trick worked great for me.
Glad I could help!
Thanks for watching
My mechanic wants to charge 3 hours labour @ $150 p/h to replace this alternator pulley. Greedy bastard
I understand the sticker shock.
Actually changing the pulley isn’t that hard however, it can be difficult to remove some alternators.
worked perfectly and now I have an impact drill, thank you
You sir are a Damn American Hero my friend! I knew that would work but was just to chicken shit to try, but I'm gonna give it a go in about 30mins and will either be in hospital or happy as hell inwas able to take the pulley off this DAMN 2006 Ford Escape without having to takeout my axle and everything if I can get this pulley off it'll slide right on out the top of my axle
Thank you!
Glad I could help.
Thanks for watching!
Somebody had to be first lol doing mine tomorrow 💯💪🏾
How did that pulley come off so easily? I’ve removed the pulley nut, but the pulley itself is stuck. Won’t budge.
Great question.
Sometimes you have to take a dead blow or a “good” rubber mallet and wack it a time or two.
@@FabRaceModRepeateventually it came off. Now… the back casing won’t come off.
So you’re trying to open the alternator completely up?
Make sure you have all the screws out.
Block the front part of the case up on some wood or other soft material. Put a bit of WD-40 or other penetrant around the bearing race. Let it soak for an awhile. Next take a block of wood (to protect the shaft threads) and your dead blow and tap litely on the end of the shaft. It should come loose. Apply more hammer force as needed HOWEVER, be sure not to damage the case mounting ears or the shaft threads.
Good luck!!!
This is soooo simple. Change the old pulley over to my new Ford alternator in about 5 minutes using my pneumatic lug nut wrench. Hardly felt the pulley move at all in my hand. Thanks.
Different kettle of fish changing the one way clutch pulleys
ABSOLUTELY!!
I need to do a video on those type.
Thank you. Should the nut be torqued to a specific amount for a pulley of that size? I'm a little worried about my impact wrench destroying something
Great question!
Technically all fasteners should be torqued to a specified amount of torque.
As you do more of the pulley swaps you’ll get a feel for the impact wrench an know to stop at a given point.
Thank you so much sir! I was battling on for an hour, pipe wrench and breaker bar. Took two off in less than a minute with a pipe wrench and my impact.
Glad I could help
Great video. I tried everything i could think of to get the pulley off (vice grips, locking alt with screwdriver etc) and couldnt get it off. Then i tried holding it and it came right off lol
Glad I could help.
Thanks for watching!
This is the single most consequential RUclips video of this millennium. A half a day of grunting and rolling around on the ground in tears was reduced to an $89 electric impact wrench (Amazon) and less than one minute of effortless pulley removal for both core and new. As easy as shown. Many thanks.

You saved my day thank you!😊
Glad the video helped!

What is the power of impact wrench you r uesing?
And please help me i want to buy an impact wrench only for Alternator's pulley. So tell me what is the power of impect wrench i want to use for this type of job done.?
Happy Monday
That impact wrench is 7.5A Craftsman. Any good impact should be able to handle an alternator pulley. Thanks for watching and for the question!
So I jus replaced my stock alternator (130 amp) with an upgraded 250 amp alternator. The voltage on the stock alt was 13.5... And with the upgraded alt the voltage reads at only 13.0... The pulley on the upgraded alt is a bit smaller than the pulley on the stock alt... could that be a reason why I'm experiencing lesser voltage on the upgraded alt? I mean do u think it will make a difference if I swapped the pulley, thus tightening the belt a lil more? Will that give me more voltage gains?
Good morning
I like to see alternator output in the 13.8V - 14.2V range. The smaller pulley will actually spin the alternator faster. It should charge better at the same engine rpm. Does the voltage go up as engine speed increases?
@@FabRaceModRepeat I haven't really ran it consistently on the freeway or sumthin. But I will and we'll see how that goes
@@FabRaceModRepeat yes when I drive down the road the voltage goes up to 15 and 16 volts. Is this a sign of a bad alternator or should I be replacing the batteries?
Video is exactly what i was looking for thanks man
Glad I could help.
Thank you brother, it worked like a champ!

No problem, glad you found it helpful
Awesome video and THANK YOU for just getting to the point and showing how it's done!
Glad I could help
Thanks for warching
Short sweet and straight to the point ♥️

I try to make the videos no longer than they need to be.
Thanks for watching.
Have a '67 C30 with a 2 belt pulley. New one came with a 1 belt. Thanks for the video.
Glad I could help.
Thanks for watching!
Never had such a face palm moment in my life lol thanks so simple it makes you feel dumb
A face palm moment…
That’s funny 🤣
Glad I could help.
Thanks for the laugh and watching
big thanks... i knew i over thought this one.. lol
It’s not hard to over think things like this😁
Thanks you sir. I get to swap pullies on my new Alternator too. Rock Auto sent the "right" alt but with the wrong pulley installed. Good thing I have an old serpentine belt hanging around to check fitment before installing on my car. I guess I will just swap on the old one. My car is a 1996 Ford Crown Vic police interceptor. The Alternator bearings are sloppy after 186k miles and the battery light goes on when revved to pass on the highway.
Happens all the time, no matter which chain you purchase through. Thanks for watching!
Best video after 4yr
Bro the glove and impact truck worked so well I’m so mad I was battling it with a clamp and impact
Glad I could help.
Thanks for watching!
Super video. I am looking for a new alternator with a 4 groove pulley. Can you tell me which one you bought?
I believe that was a Doorman unit. If you find the alternator that will fit your application you can usually find a pulley to match your existing belt.
Thanks for watching.
Are alternator shafts all the same size?
Great question!
Like most mass produced item they similar across the industry. They are only the same across a given manufacturer.
I see. So I need to check and make sure my pulley will fit the new alternator. Thanks!
@ThePeanutization
Exactly.
Thanks! Never done this before but that looked real simple
Thanks for watching!
Glad I could help.
Turned a “hard” job EASY!! Appreciate your video.
Thanks for watching, glad the video helped!
Most helpful video
Glad you liked it.
10/10 video
What about APT pulley how’s that done or could o replace clutch with regular pulley ?
Great question!
Ive only dealt with a few so far. The cost of the clutch tool tends to be high. I’m sure that will change as more and more clutch’s wear out.I just went with a replacement alternator. I’
@@FabRaceModRepeat We never had clutch pulley 20 something years ago whuy cant i just put a regular pulley instead
@@myviews469
Nothing says you can’t.
Great video
Thanks for the video bud. Wasn't sure if I could do this or not
Glad to help.
Thanks for watching!
This pulley almost fell off. The problem is when the pulley is stuck on the shaft. The pully is V shaped and the puller slides off.
I wanna say thank you I had a hard time with this alternator I saw your video and you save the day I wanna ask you a question why is my brand new alternator is making a whining noise after I change the pulley from a 5 Grove to a 6 Grove pully with a new belt it sound like a supercharger lol
Thanks for watching
And glad I could help.
Just because it’s a new alternator doesn’t mean it’s a good one. It could be a bearing, bad rectifier or a warped shaft making it whine. I’ve seen quit a bit of that in recent years.
@@FabRaceModRepeat what I'm gonna do is take it back to the auto store that was a lot of work definitely on a maxima
Indeed!
Thanks for your help bud 😊😊😊
Glad I could help
Thanks for watching
I would imagine the procedure would be the same to take off a v-belt pulley and replacing with a multi-grove pulley on a alternator which originally had a v-groove one.
Yes, process is the same. V-belt or grooved
Great advice, thank you!
Glad it helped.
Thanks for watching!
What is the size of that socket?
I’ll have to check. Not driving the dodge today. I believe it’s 22mm.
Well done, but isn't it a little scary grabbing the pulley and then loosing it with the impact?
I can see a hand full of stitches!!
May Cooper
Yes, that’s why I should’ve been wearing gloves. You do need a good grip to perform this task.
Thank You, good trick. Did it today 👌
Glad I could help!
Thanks for watching
Perfect right to the point!!
I wish I could hit it that perfect on all my videos!
Thanks for watching
i love impact guns
They are a very helpful asset.
what size socket was this
It varies from car to car, how ever it’s typically in the15/16” range
Thanks😊
Glad it helped!
Thanks for watching
Whats the name of that removal pulley???
What kind of impact gun is that?
Evening
It’s an older craftsman.
@@FabRaceModRepeat I think I found one on Ebay. Thanks! Merry Christmas!
Stop the Philosophical Zombies
Nice find.
Merry Christmas to you aswell
What vehicle was this from and what year?
Great question..
96 Dodge Ram 1500.
The procedure works on almost any alternator. Some of the modern clutched alternators need special tools to remove the pulley.
@@FabRaceModRepeat nope it’s perfect. 97 ram 5.2 I’m going to take the under drive pulley kit off because it messes with my charging. I can’t idle and run ac and lights on without it dropping below 12v.
That’s the down side of under drive pulleys.
@@FabRaceModRepeat would you mind telling me where you got the new alternator pulley I need one and can’t find one anywhere for some reason
TheDundie54
I believe the pulley came from dorman.
Could you do the same thing using an oil filter wrench to hold the pulley?
I would be concerned about it slipping. I have seen a strap wrench used to hold the pulley before.
Why did you change the pully was it noisy
Thanks for watching
The one on the new alternator was smaller diameter than the one off of mine.
do i go clockwise or the other way ?
Typically counter clockwise however there are a few applications out there that go clockwise.
Upvoted. Upgrading my 2004 Silverado to a 145 amp 'nator, and the pulley on the new (reman'd) part was too big, the belt wouldn't fit. Thank goodness for the 1/2 drive electric impact I bought years ago too! Swapped them out, and my truck is better than new! Thank you for this video!
