Harmonic Balancer or front crank seal replacement 99 Blazer.

Replacing the front seal on a 4.3 Chevy.

[@user-yi2gu7ce9w]

obviously a very experienced mechanic , I just stumbled onto this video as Ive just bought an 89 chevy 2500 with a wobbling harmonic balancer that I later discovered as the timing went south great video great teaching funny guy too

[@thefixerofbrokenstuff]

Thanks

[@Jeremiah.1]

You are a very detailed step by step master mechanic Others here in youtubers don't describe little details Thanks for sharing a very close video how to remove the harmonic balancer

[@thefixerofbrokenstuff]

My pleasure

[@dandavis9071]

Fantastic video. I wish everyone making car videos were as articulate as this gentleman. Gonna do my front seal as soon as the weather gets nicer. SO GLAD I WATCHED THIS VIDEO.

[@thefixerofbrokenstuff]

Hey, thanks. Reckon this is the first time I've been called articulate.

[@atzgfq23]

just droping this here, your "fancy seal puller" was the best idea ever for real ! thanks @@thefixerofbrokenstuff

[@rnastyboii]

The commentary on this video is great! “life hurts a lot already but it hurts worse if you’re stupid” 🤣 definitely going to use that now. Also easily understandable and to the point information

[@thefixerofbrokenstuff]

Thanks

[@Macleod1991]

Great video. A tip I will add is that you can make a slip wrench out of stuffing the serpentine belt in the box end of a large wrench then wrap it around the pulley, then use the wrench to hold it in place while you apply torque.

[@thefixerofbrokenstuff]

Thanks

[@BiggousDiccous]

Never seen the screw/prybar trick for the seal. That was awesome lol great video

[@thefixerofbrokenstuff]

Wish I was the first one that thought it up

[@BiggousDiccous]

@@thefixerofbrokenstuff no kidding. Do you think it's possible to pull the balancer without removing the radiator? Or not worth the risk

[@thefixerofbrokenstuff]

I wouldn't. Way too many things could go wrong.

[@willferg239]

Buddy, I could hug you right now. As thorough and detailed as I am. Much thanks

[@thefixerofbrokenstuff]

Glad it helped

[@thesmitty957]

When I saw your fancy seal removal tool, I was upset at myself for not thinking of it. Lol! Thanks for the vid.

[@thefixerofbrokenstuff]

Gotta admit, not my idea.

[@Jeremiah.1]

Keep loading more videos you are very good teaching step by step

[@thefixerofbrokenstuff]

Thank you, I will

[@blackdogisinthehouse]

Excellent video! I have a 96 Blazer that the wife is giving a bad rap about oil on the drive way. I have been debating replacing this seal, and after watching you do it I have no excuse not to. After all, it is probably easier than changing the spark plugs, at least the middle one on the driver side. Thank you for this info!

[@thefixerofbrokenstuff]

No problem. Eyeball the oil filter relocation kit. Very prone to leaking as well.

[@FoolintheRainSDMF]

Same, I have a 97 that loves marking territory so much that it would make it lose territory if it keeps on lol 😂 so I have to do this and quite a few other things after I de grease stuff and can see more of whats going on.

[@thefixerofbrokenstuff]

Before you clean anything, eyeball it hard. When you find the clean spot, you've found the leak. The leak will keep the grime washed off.

[@FoolintheRainSDMF]

@thefixerofbrokenstuff definitely a good point I do want all that oil grease and grime off but you have a good point that oil runnin steady would look a lot different than the stuck old shit

[@jttj1254]

You are a big time helper with detailed procedures… gracias

[@thefixerofbrokenstuff]

Think nothing of it

[@RCSmith90]

Thank you for posting this video. About to do this on my 96 pickup with the 5.7 vortec.

[@thefixerofbrokenstuff]

Cool. Careful of the plastic.

[@AaronEngineering]

As a former spanner monkey (over 20yrs ago), I’ve never seen a plastic timing cover before. Great tip on installing the seal like that too. Brought back memories. Cheers 🍻. Aaron

[@thefixerofbrokenstuff]

Thanks.

[@cliffords.8341]

@Aaron Engineering I was surprised to see my timing cover on my 1997 GMC S-15 With the Vortex V-6 had a plastic timing cover. Being a motorcycle technician and machinist, I didn't see any plastic engine covers in the power sports industry. It's a way for the manufacturer to save money, but still raise the price of the vehicle. 😁

[@thefixerofbrokenstuff]

Not really.

[@AaronEngineering]

@@cliffords.8341 Hey mate, I'm with you. I had never seen plastic covers until the late 90's when GMH (Holden) over here in Australia were importing V6 Buick motors for their Australian made Commodores. They too had plastic rocker covers. Cheers, Aaron.

[@thefixerofbrokenstuff]

There's a lot of parts on a modern engine that's plastic, simply because it could not be made from stamped steel. Yes it could be made from die cast aluminum, but that would be orders of magnitude more expensive.

[@Jeremiah.1]

Im working now on 4.3 Chevy Silverado is same like your video showing you save me lot time trying to find the correct harmonic balancer puller

[@thefixerofbrokenstuff]

Think nothing of it

[@s10-Mike]

Dang. That was the coolest way to pull out a seal that I've ever seen. I subscribed just because of that. I actually just came across you because I have to do a flywheel on my s10 and was gonna do the rear main seal while it's apart. I also need to do my intake gasket so I ended up buying a whole gasket kit and just figured I would do all that I can since most are seeping oil anyway and my crank seal is pretty bad aswell. Thanks for the cool tricks I hope there are more s10 videos . I have 2 and a sanoma and am always tinkering with um

[@thefixerofbrokenstuff]

There's a playlist of shake away stuff. I've got 4 S10s on the road. The best part is, if you have that many, you never have to put your wrenches away.

[@mikef-gi2dg]

I like how you drove the seal in without beating, I am going to have adapt that method in on every seal it was slick and not threatening.

[@thefixerofbrokenstuff]

It pays to be gentle on 25 year old plastic.

[@beasyphone]

Had to add...I work at a Mack,Volvo,Hino,UD,Cummins Dealer. We use blue loctite on everything that Mack calls for ; which is everything lol. They rarely mention antiseize but also common place. I ALSO heard "yinz" early on the first watch and giggled to myself as I'm a Field Club boy, (Fox Chapel) n'at. Then "watch for deer" and thought...yeah, that's a PA thing.. still have family up thatta way. God bless guys. And thanks for the trick again, I get a couple deck screws ready for this weekend as I'm PRETTY sure the tools I have at work are a BIT LARGE for my little S10

[@thefixerofbrokenstuff]

I'm in the Ozarks. You ns is what some say.

[@beasyphone]

Just discovered my front main the other day while checking and greasing my front end. I've git 60k on a full build/ billet crank, forged bottom to top, but at this point...it's my daily lol. Thanks for the video, little less daunting. I have Zero other leaks (go figure at 60k) but wanted to hear other opinions , so yeah. Gonna go ahead and knock this one out.ps- the 4.3 marine intake solves all the "up top" issues and is relatively inexpensive to do. All the best! Cheers

[@thefixerofbrokenstuff]

Getting there is the hardest part

[@joca1624]

👏👏👏 Great job,nicely explained.

[@thefixerofbrokenstuff]

Thanks.

[@zjtr10]

Good job! Thanks for sharing the information

[@thefixerofbrokenstuff]

Your welcome.

[@chrispulieri9543]

Excellent video

[@thefixerofbrokenstuff]

Thanks

[@mrdrproffesornoam]

"thats how you know they oil in em" that statement alone is how i know i can trust this video

[@thefixerofbrokenstuff]

If it ain't dripping, it's already too late

[@jimdunne1900]

Thanks for sharing! Good info!

[@thefixerofbrokenstuff]

Hey, you're welcome

[@dano4572]

VERY NICE , SIR!!

[@thefixerofbrokenstuff]

So nice of you

[@johnszwarc1985]

A trick I found that works great for installing balancers is to put it in the oven at 250 degrees ,for 10 or 15 minutes , not hot enough to melt the seal but hot enough to make the the balancer tap on easier with a small amount of oil On the snout inside and out, try it .

[@thefixerofbrokenstuff]

They go on easy enough with a pull bolt. I'm too chicken to put the balancer in the oven.

[@youtubr4real]

Good video

[@thefixerofbrokenstuff]

Thanks

[@s3nrdiz1904]

That’s a nice 5/8 length of 2” dwv pipa!!

[@thefixerofbrokenstuff]

Sure

[@tarynpreston9568]

Appreciate you brotha

[@thefixerofbrokenstuff]

Thanks

[@danielhdz4]

Great vid thanks

[@thefixerofbrokenstuff]

My pleasure

[@soulstarr4998]

Your funny 🤣😅🤣 good vid

[@thefixerofbrokenstuff]

Thanks

[@johnt.3799]

Did you remove the radiator for extra room? Can this be done with the radiator still in the truck?

[@thefixerofbrokenstuff]

I had the whole front clip off. At a bare minimum a body should remove the radiator.

[@djrisberg]

Thanks for this...my Blazer is slinging oil like a baseball team spits chew during a close game...thought I'd have to pull the timing chain cover to replace the seal...this looks like less than a hour's work...any chance you can get your pinky inside when the seal is out to assess the play in the timing chain?

[@thefixerofbrokenstuff]

No. There's a slinger

[@thefixerofbrokenstuff]

Oh, and it's supposed to leak. That's how you know there's oil in it.

[@djrisberg]

@@thefixerofbrokenstuff I see it as public service...involuntary asphalt sealing...

[@thefixerofbrokenstuff]

Exactly. Keeps the weeds down in the driveway too.

[@lg2081]

Is there a certain type of silicone you'd rather use or just a general auto?

[@thefixerofbrokenstuff]

Is all tastes the same

[@lexustech48]

Ford engine sealer and Toyota black FIPG are pretty baller. Better than Permatex IMO.

[@jameswilliams5428]

how far in is the seal supposed to go? till it stops or till flush?

[@thefixerofbrokenstuff]

A little past flush if I remember right. I don't seem to remember a place for it to seat against for a stop.

[@johnrankin9129]

What size was the big bolt on the pulley?

[@thefixerofbrokenstuff]

Don't remember

[@dgc940]

Did it keep leaking? Looks like whole cover is leaking more than the seal was?

[@thefixerofbrokenstuff]

It was mostly the China wall. Both ends were blown out like a prolapsed Hamp pig.

[@user-xn6vy8ju7e]

What kind of grease and sealant did you use?

[@thefixerofbrokenstuff]

The kind that was laying on top of the pile. It don't really matter.

[@dday9158]

Can u just put it on drive to prevent engine movement?

[@thefixerofbrokenstuff]

No. That's not how an automatic transmission works.

[@GraeboProductions]

Yep I got oil in my truck 😢 wet from the power steering hydraulics to end of my transmission 😮

[@thefixerofbrokenstuff]

It's an added benefit. Don't have to spray for weeds in the driveway.

[@WesternBlazer]

How do I get the pulley off without the motor turning over

[@thefixerofbrokenstuff]

Hold your boot against the balancer, or use a strap wrench on it.

[@WesternBlazer]

@@thefixerofbrokenstuff Got it! Thanks for the video. Now my 93 blazer isn’t pissing oil anymore😂

[@thefixerofbrokenstuff]

Glad to hear it.

[@marcwaters5001]

When it comes to Chevys, if it ain't leaking, it ain't running.

[@thefixerofbrokenstuff]

Yup. Self changing oil system. Fancy.

[@ericg4915]

Obviously that was a joke but it's true that the oil sweat all under my motor has protected it from the salt haha

[@thefixerofbrokenstuff]

You must be talking about the undercarriage corrosion prevention system that generous motors designed into the rigs.

[@mariorobertosinaysilva9754]

Tienes el número de ese sello, con que número lo compro yo necesito comprar uno, porfavor.

[@thefixerofbrokenstuff]

Sorry. No.
