Loosen Crankshaft Pulley Bolt by Bump Starting the Engine | Loosen Harmonic Balancer Bolt

- The crankshaft pulley bolt was stuck on my 1995 Toyota Camry, so we used the bump-start method to loosen the bolt. Bumping the engine worked l like a charm.

Man I've been stuck for 3 hours on this bolt and I have the proper tool which did not work this method is gold thank you for so much help I love you lol
LOL! We love you too, Wreckless10. Merry Christmas!
This is by all means the most thorough explanation and instruction i have seen in 10 years. Awesome video ❤️
That's one of the nicest comments I've ever received, Ayman. Thank you for that. I'll pass it along to Sister.
Thank you for saving my sanity with a Mitsubishi Canter. The crankshaft pulley had a catastrophic failure on the highway.
You're welcome, Skadi. I'm glad the video helped you. ;)
To my astonishment and relief this method worked. 97' Camry V6 1mz-fe happens to have the exact pulley location. Thank you!
That's wonderful to hear, FFFEZZYYY! You're welcome.
Honda crank bolts used to give me fits. Then, I bought a Milwaukee M-18 2767-20 impact gun and haven't looked back. I use a weighted crankshaft socket from Lisle. This setup has never failed me. While I accept that the starter "bump" method will work on many cars, it is important that the crankshaft be rotating in the clockwise position while cranking the engine. Otherwise, you would be tightening the bolt. Should one decide to use this method, may I suggest using a 1/2" breaker bar instead of a ratchet? The breaker bar should be stronger and you wouldn't be taking a chance of breaking the teeth inside of the ratchet head.
This technique works 💪🏻
I like the way it worked. I'm surprised the ratchet didn't break. I would have used a small breaker bar.
Yep, me too. ;)
Done that many times when I was wrenching back in the 90s.
VERY SMART..NICE JOB!
Thank you, Frankie.
Did the same today thanks for your video i use to do it 25 years ago and i was a little scare to do it again but works Honda accord 2004 v6
WONDERFUL to hear, Yavier! You're certainly welcome, and thank you for the thoughtful comment.
Been a mechanic for the last 45 years This is a good method, but be aware most modern cars do not have key ways to locate the pulley, and this is the only way to keep tension on timing belt pully check your vehicle before you use this method you could bend your valves or even worse.
Good method after all else failed. Good job
Thank you, pnweezy.
Corolla? About to do this on mine. Great video, thanks for sharing!
You're welcome, Sarah, and thank you. Mine is a 1995 Camry, and good luck on yours!
Thank you very much, nice job
You're welcome, and thank you.
Very nice method, however I am stuck with civic 2003 EP1 crank pulley, and since engine rotating CCW I cant use the bump method right? I guess I would tighten bolt even more
Thanks for this! I have a CA Camry and didn’t know about that extra wire. Haven’t started yet so I’ll be sure to remember to disconnect that wire.
You're welcome, W S. Just remember--just BUMP the engine, but don't start it. Make sure that whatever material, like wood, you use to wedge between the ratchet handle and the upper body of the car is solid and won't allow the ratchet to give or move too much. I wish you great success! It's thrilling when the crankshaft bolt gives way. When you torque the harmonic/crankshaft bolt back on, torque it to 80 ft. lbs. Happy DIYing!
DeWalt 950Nm impact driver would get that off
@@bEEBO178 borrowed an impact from my neighbor and it worked 1st time. Did the entire timing belt job by myself on the first try. Pretty happy with that result.
@@frugaldiy1 How do you avoid accidentally starting the engine? Watching the video I thought removing the spark plug wires ensures that the engine won't start?
@@purelogic3595 You take the spark plugs wires off the spark plugs cuz then no sparky. Don't risk it. Don't fully rotate the key in the ignition. Just give the key a slight "bump."
How did you tighten it back up?
Did you have your timing belt on when you bumped started it?
Will this mess up the timeing ?
Or can it brake something in the inside
U save me 1000 bucks 🎉🎉
Wonderful, Luis!!! I love to hear that. ;)
Only way I would do it
Me too. ;)
I’m trying this now but I’m too scared to do it lol
Yep, it's a bit of a nail-biter moment for sure, Anubis. I understand your feeling. ;)
Wow, how do you fix the bolt back? A hammer with the wrench would work?
I'd like to help you, Irosh, but I don't understand the question. Please clarify what you mean, and I'll try to help you.
@@frugaldiy1 after replacing the harmonic balancer pulley, how do you fix the bolt again? Hand pressure would enough?
@@iroshwimaladharma5840 you will need to find the torque specification for your vehicle, relative to that part. Then you set the wrench to your desired torque spec and ratchet like normal. As you tighten the bolt with the torque wrench, when you hit the chosen setting it will "click", and you'll know that you got it to the correct tightness. (Two more tips: Practice using the torque wrench on some inconsequential bolt. Start with a weak/light setting and work your way up a couple times to a tighter setting. This will give you confidence in how you're using it before you tackle a serious bolt like this one. Next--never use your torque wrench for anything other than tightening bolts during the assembly process. This will help maintain it's "calibration". I specifically mean, don't be using it to remove bolts, and personally, I wouldn't use it on bolts that are no big deal, either.) You're probably watching this vid anticipating some serious work so, good luck!
This won't work on an engine that cranks counterclockwise (such as a Honda Accord)
....
Will this work on 03 buick lesabre?
I can't answer that because i'm not familiar with that engine. If it helps, my Camry engine rotates clockwise.
Yeah a Female mechanic !!!!
LOL! You made me laugh, Lisa. Thank you for that! Sister and I enjoy working on vehicles and all sorts of projects. They're gonna have to pry our many tools out of our cold, dead hands. ;)
my 300k mile bmw said no to this method, or any else :D
I realize we are only bumping the engine and not starting it, but is there any chance of timing belt skipping?
It didn't on my car.
@@frugaldiy1 Yes why the wrench drops when performing this. Of course force of the crank turning is much higher than the wrench holding the bolt. I believe the engine still turns counter a bit with the timing belt attached. I have one more method to try before trying it your way. Thanks for the video.
The racket drops because it loses tension when you bump the engine. You're welcome, simple.
I finally did it your way because nothing else worked. I used a long breaker arm and placed it against the lower control arm. It worked like a charm. Btw… torque on this bolt for my Solara is 169 ft/lbs. I used a compact wrench with 250 ft/lbs and still couldn’t get the bolt off. Timing belt had been changed before. Any idea why some bolts are torqued so high?
Wonderful to hear! I'm glad it worked for you. Yes, the reason some bolts are over torqued, like mine and yours, is because folks use an impact wrench to tighten the bolt, instead of a torque wrench, and they over tighten the bolt. It's a lazy person's way to do it. Tighten the bolt to torque specs when you put it back on and you won't have a problem getting it off in the future. ;)
😂😂😂😂😂😂😂
NO !!!! DO NOT DO THIS or prepare for injury and or massive damage, just buy the right tool ffs
That's Rong and this is old mentality our time of engines this may damage your engine complete.
Why does everyone loosen the shit and never take the bolt out.... 🤬🤬🤬
