Shredded Engine Drive Belt. Why? Harmonic Balancer Failure.

[@k6-3spetznazhelmet]

I personally own a 2RZ-FE engine so this video definitely helped me out diagnose issue with the engine further down the line if they come up.

He didn't give any tips and show special puller/tool. For the alternator belt, dont go straight to the adjustment bracket, the main pivot bolt on the alternator has to be loosened, loosen lock bolt, then you can back out the bolt on the adjustment bracket to remove the belt

Petr, It looks like the owner got it to you just in time so take good care of that genuine, made-in-California Tacoma. Once you have replaced the harmonic balancer, 🎷 that engine should sing sweet music for another 20 years 🤩

Great information

[@toycoma98]

Good information but no tips and guidance, no procedures on how to do the job.

[@koomo801]

Same thing happened to my '00 Tundra V8 after a mechanic abused it back onto the spindle after a timing belt change. It began squealing immediately, and before I had a chance to return it to have the balancer replaced it completely separated and disintegrated, taking out the cam position sensor with it. If you see it wobbling, replace it immediately!

Good job, Peter! 👍

My 3 V belts have done 104,000km, 18 years old. They are genuine and still in good condition.

Awesome video Peter.

[@paulodisano502]

Thank you for the informative video, Peter. Cheers from Canada 🇨🇦🇺🇸

[@toycoma98]

You should've shown how you took the balancer out and showed the pully holder to remove bolt, and tool/puller to remove balancer. Also give a tip about the alternator, dont go straight to the adjustment bracket, the main pivot bolt on the alternator has to be loosened, loosen lock bolt, then you can back out the bolt on the adjustment bracket to remove the belt.

I really did lol with the garbage truck comment & video proof !

[@CouchMan88]

I had a bunch of belt shrapnel on an old Cadillac. At first I replaced the idler pulley that was a bit off. Later I noticed a wobbly water pump and that was my real issue. On older GM cars the harmonic balancer has a 2 piece design held together with rubber and when it deteriorates it goes bad and wobbles or spins much like this one.

good video, and nice truck

[@henrykiser8880]

Thanks for making these videos. I enjoy them. You do great camera work too.

[@DIYDaveOK]

How goes the Tundra rebuild?

[@Pallidus_Rider]

What about the oil buildup around the engine behind the harmonic balancer?

[@CouchMan88]

He addresses that at the end of the video. He is going to replace the seal, harmonic balancer and the belts.

[@Pallidus_Rider]

@@CouchMan88 I must have missed that - thanks 👍

[@toycoma98]

Front main seal, he will be replacing it.

[@wolfeadventures]

Great video.

[@augustinep6193]

Good. Thanks.

[@heidimelcarek3677]

I was just doing my learning about harmonic balancers bcz mine is making a rattling noise n I just observed today that the bolt wobbles slightly when the engine is running. I wanted to find out how much time I'd have to replace it. The new one will take 10 days to get here. I feel like it should be ok. I'm also putting on new belts, tho at the moment mine are fine.

[@efil4kizum]

are these Common to Fail on the 5VZFE 3.4 litre?

[@jimrossabrena7955]

What caused the harmonic balancer to break so early? 285k on my Taco (2.4l 2wd) and my harmonic is still holding on

[@toycoma98]

Its got low miles, so i think its not being driven enough. The rubber probably dried out from sitting.

[@mochachoco1820]

Most likely the balancer bolt was not torqued to the specified load.
