ALRIGHT BUNDYS GARAGE BUNDY HERE HEY TODAY
WE ARE WORKING ON A CRANKSHAFT PULLEY ALSO KNOWN AS A HARMONIC BALANCER RIGHT HERE WE
HAVE A GOOD ONE RIGHT HERE WE HAVE A BAD ONE ONE THAT’S BROKEN AND I WANT TO SHOW YOU GUYS
HOW TO FIX THIS BEFORE WE MOVE ON IF YOU CAN PLEASE SUBSCRIBE TO BUNDYS GARAGE ON YOUTUBE
I COVER EVERYTHING RELATED TO AUTOMOTIVE IF YOU CAN SUBSCRIBE IF THIS VIDEO HAS HELPED
YOU OUT OR ANY OF MY VIDEOS HAVE HELPED YOU OUT GO AHEAD HIST THAT SUBSCRIBE BUTTON HIT
THAT BELL FOR NOTIFICATIONS EVERY TIME I UPLOAD A VIDEO SO YOU DON’T MISS ANY OF IT BUT IT
REALLY HELPS ME OUT THIS CAME OFF A 1992 HONDA ACCORD WITH A 2.2L F ENGINE AND WHILE I WAS
TAKING IT OFF IT WAS ALREADY BROKEN THE COVER HAD WEAR MARKS ON IT LIKE IT’S BEEN EATEN
THROUGH LET ME SEE IF I CAN FIND THAT COVER REAL QUICK SO THERES THE COVER AND RIGHT THERE
YOU CAN SEE THIS IS WORN THROUGH SO THE CRANKSHAFT PULLEY HAS BEEN DAMAGED FOR AWHILE RUBBING
THERE ATE ALL THE WAY THROUGH THERE HARMONIC BALANCER HAS BEEN BUSTED FOR QUITE A BIT OF
TIME SO I PICKED UP THE VEHICLE FOR A CHEAP PRICE BECAUSE IT HAS A BROKEN TIMING BELT
AND I’VE BEEN SLOWLY FIXING IT REPLACING IT AND GETTING NEW PARTS FOR IT A NEW HARMONIC
BALANCER IS ABOUT 100 BUCKS AND THAT’S ALMOST HALF OF WHAT I PAID FOR THE VEHICLE SO I DON’T
WANT TO BUY A NEW I’M GOING TO TRY AND SAVE THIS ONE AND THE WAY I’M GOING TO DO THAT
IS JB WELD WORLDS STRONGEST BOND REAT FOR HOUSEHOLD REPAIRS AUTOMOTIVE PLUMBING MARINE
CRAFTS AND MORE WORKS ON MULTIPLE SURFACES METAL WOOD PLASTIC TILE PCV GERMANIC FIBERGLASS
CONCRETE AND MORE I PIKED THIS UP FROM OREILLY AUTO PARTS THEY HAVE A QUICK DRY ONE I BELIEVE
AS WELL BUT I DECIDED TO GO WITH THIS ONE CAUSE I’M NOT IN A REAL BIG RUSH FOR IT TO
SET UP STRENGTH 3960 PSI SET TIME IS 4 TO 6 HOURS CURE TIME IS 15 TO 24 HOURS AND CURE
COLOR IS DARK GRAY SO I DON’T REALLY CARE ABOUT THAT THERE ARE ALL THE INSTRUCTIONS
FOR THE JB WELD IF YOU WANT JUST HIT PAUSE RIGHT NOW SO YOU CAN SEE ALL OF THEM SO I’M
GOING TO GO AHEAD AND CLEAN ALL THIS UP SO RIGHT HERE WHERE THE LASER IS HITTING AT RIGHT
THERE THAT’S RUBBER THERE’S A THIN RUBBER SEAL THAT GOES ALL THE WAY AROUND IT AND THEN
YOU HAVE THIS STEEL BAND THIS IS ALL STEEL THERE’S NO RUBBER ON HERE ON THIS GOOD HARMONIC
BALANCER ON THIS ONE THAT’S INTACT THE RUBBER SEAL IS RIGHT THERE OK SO I’M GOING TO TRY
AND CLEAN THIS UP AS WELL AS POSSIBLE I’M GOING TO GET A PIECE OF SANDPAPER OR A FILE
AND TRY TO FILE THIS DOWN TRY TO GIVE IT SOME KIND OF AN EDGE A BITE ONTO THE STEEL FOR
THE JB WELD TO HOLD ONTO USE SOME BRAKE CLEAN THEN I’LL SAND IT ON BOTH SIDES THE ONLY BUMMER
PART ABOUT THIS IS THE FACT THAT THESE ARE ACTUALLY I WANT TO SAY CLOCKED BUT THEIR BALANCED
AT A SPECIFIC LOCATION AND I DON’T KNOW WHAT THAT LOCATION IS BECAUSE IT WAS ALREADY BROKEN
WHEN I GOT THE VEHICLE SO WHEN I DID TAKE IT OFF I SPRAY PAINTED IT WITH YELLOW SPRAY
PAINT JSUT SO I COULD REMEMBER KIND OF ROUGHLY WHERE IT CAME OFF AT AND THEN ALSO IF YOU
NOTICE HERE SO CHECK THIS TOO ON THE OUTER RING ONE SIDE IS HIGHER THAN THE OTHER YOU
GUYS CAN SEE THAT ONE SIDE IS ACTUALLY HIGHER THAN THE OTHER SIDE SO JUST MAKE NOTE WHICH
SIDE IS HIGHER IF THERES A DIFFERENCE ON YOUR SPECIFIC CRANKSHAFT PULLEY HARMONIC BALANCER
SO LET’S CLEAN THIS CRANKSHAFT PULLEY UP AND I’LL SHOW YOU WHAT TO DO YOU WANT TO MAKE
SURE THE SURFACE IS OIL FREE BEFORE YOU PUT ON THE JB WELD SO THE JB WELD HAS THE PROPER
BONDING SURFACE TO ADHERE TOO SO I USED THE FILE TO GO AROUND ALL THE EDGES GETTING ANY
RUST LEFT ON THERE I’M ACTUALLY GOING TO GO AHEAD AND GET A SMALL IT’S LIKE A GRINDING
WHEEL YOU PUT ON THE END OF A DRILL AND JUST CLEAN THIS UP A LITTLE BIT BETTER IT’S NOT
NESESSARY BUT IF YOU HAVE IT GO AHEAD DO IT BECAUSE YOU WANT THIS SURFACE AS CLEAN AS
POSSIBLE BEFORE YOU PUT THE JB WELD ON SO IT’S A LITTLE STEEL WHEEL GOES RIGHT INTO
THE DRILL YOU CAN PICK THESE UP FROM ANY HOME DEPOT LOWE’S ACE HARDWARE ANY LOCAL HARDWARE
STORE YOU HAVE IN YOUR TOWN MAKE SURE YOU WEAR SAFETY GOGGLES WHEN YOU DO THIS I CAN’T
STRESS THAT ENOUGH WEAR SAFETY GOGGLES WHEN YOU DO THIS I KNOW A GUY WHO HAD AN AUTOMOTIVE
SHOP AND HE GOT A LITTLE PIECE OF STEEL IN HIS EYE AND NOW HIS EYE IS INFECTED AND HE’S
ALMOST LOST ALL VISION IN HIS LEFT EYE SO IT’S NO JOKE NO JOKE I ACTUALLY USE THIS WHEN
I’M DOING STUFF AND IF YOU WANT TO DOUBLE UP EVEN BETTER SCUFFED UO THIS AREA RIGHT HERE JUST WANT
ALL THE WAY AROUND STUFFED THIS UP GOT MOST OF THE RUST OFF I’LL HIT IT AGAIN WITH SOME
BRAKE PARTS CLEANER CLEAN IT UP JUST ONE MORE TIME DO THE SAME THING HERE LIKE I SAID EARLIER
BEFORE MAKE SURE YOU KNOW WHICH WAY IS UP ON YOUR OUTER RING WHEN YOU PUT IT ONTO THE
INNER CIRCLE HERE ALRIGHT I’M GOING TO USE THIS OLD AIR FILTER BOX THAT I HAVE TO MIX
UP THE JB WELD SO THE INSTRUCTIONS ARE PREPARE CLEAN REPAIR AREA OF DIRT GREASE OIL PAINT

APPLY WITH AN APPROPRIATE TOOL AND EVEN COAT WELD BEAD OR EXTRUDED SHAPE AS NEEDED AND

    what are the symptoms of one going bad? does it make the same sounds like the tensioner pulley?

  • Reply David Hollfelder May 7, 2019 at 10:41 pm

    There’s likely a timing notch on the ring that lines up with the key way on the middle part.

    Would it still do it's job at absorbing vibration If you use JB weld instead of a rubber ring?

  • Reply stangmaster 2 June 29, 2019 at 2:34 am

    The balance is assembled at the factory, HOT.
    That causes the parts to weld together, with the rubber.
    It is a press fit, done with a hydraulic press.
    Then, it is bolted to a balancing machine taking into account a certain clocking.
    If not clocked right, you will set vibrations that could destroy a bearing or so.
    JB weld is not flexible, and you Mickey Mouse repair may cost you a radiator, AC condenser, and shrapnel damage under the hood, and possibly hurt innocent bystanders.
    You should have spent the $100 or so, instead of rigging up a time bomb.

    Do you have a brother named Al?

    Wear gloves. Don't touch the epoxy. Coating both surfaces is ideal for such a high strength application. Wish you had video of your results instead of just hearsay. Thanks for the info! Liked. Subscribed.

    It will work fine for daily city driving, its when you hit the freeway and it needs to absorb resonance, that will eventually cause inner engine damage. Its a great fix until you can get a new balancer.

    Well Bundy its been 3 months does it still work? I'm leaning towards no…

    Reminds me of what I deal with when I'm doing a repair at 6:31😆

    Yo lo hice con resina en lo que me llegaba la polea que compre en ebay.

    JB WELD HAS BEEN VERY DISAPPOINTING FOR ME , TERRIBLE FOR METAL GLASS OR PLASTIC SIMPLY DOES NOT WORK

  • Reply Phillip Smith September 9, 2019 at 11:45 pm

    So how do you get a crankshaft bolt off without the pulley being on it? I am rebuilding a 2.2 liter Honda accord, spun the engine to make sure pistons and rings were okay. Now I can't get the crankshaft bolt off. Help!

    HOW TO MAKE A TICKING TIME BOMB 101!!
    Don't cheap out on important parts.
    This car should not be on the road, the guy who has been working on it is a rank amateur!

    So did it work long term?
