If you do not lock the cams at tdc the crank sprocket ( that is not keyed to the crank) will likely turn as it is held in place by being squashed between the balancer and the front of the crank. A cam lobe with the valve compressed can make the cam turn and spin the sprocket on the crank a few degrees and now your timing will be way off, bent valves etc when you start it....... get the right tools and a new bolt as it is a stretch bolt you can only use once. torque it properly too.
Keep searching. There are better videos than this. Tech did not verify he was at TDC before and after pulley bolt was torqued. Also a new bolt and friction washer should be used.
Jerry, are you implying that only people who video their work and post it know what they are talking about? Guess I need to confront my Mazda tech friend about this. Scammer's been working on my car with no videos, dammit!
Baxrok2 has some excellent videos for setting timing. Search his name. And then watch them a few times as once you get the concept it’s relatively easy process.
Using that impact wrench on the pulley bolt is the main problem when you want to unscrew it again. You can't precise set and control the torque on that impact gun. If the manufacturer says that this bolt requires two stage screwing, first to 100 Nm then turn another 90 degrees, the unscrewing shouldn't require excessive force, unless someone "wise" used an impact gun on the bolt and tighten it to much. When you need to unscrew the bolt it would be much better to lock the pulley with a special holding tool and use a hammer and a manual impact wrench on the bolt.
so i took my pully off without setting to TDC or putting that tool in to lock the crank? what are my options now am i able to just rotate the engine to TDC and put this on?

You might get lucky this way but I would hold the balancer with a spanner wrench. Notice the crank moving when he takes out the bolt? He also did not torque the bolt correctly. The torque needed would shear off the temporary little bolt in the balancer. Where is the friction washer? I would not trust this repair for long.
Timing peg was not all the way in. Never reset crank to TDC. This is a hatchet job more than likely ran like shit after this job was done. If you're gonna do an "instructional" video, show everybody the proper way. This will end up blowing someone's motor.
That bolt has to be torqued to atleast 72ft lbs then another 90 degrees or else that bolt will back up and your engine will be done.

No wonder mine runs extremely sloppy and turns off lol

Oh jesus....where's your video?
And it wasn't torqued down. I'm in the process of doing this and looking for more info and tips but I know enough to know this isn't right!

@@jeffbirt8874 ask your tech friend where I can get a replacement damper pulley from for my 04 Mazda Atenza
Good video help me a lot
Helpful!! Thank you!
This is what you get name brand mechanic shops. People that do hack jobs.

You need special service tools to do that lol

Great video. I was thinking that you have to hold the camshafts with the special tool, But seems that is not necessary.

Does anyone know the size of this small holding bolt please?
@@SimonM5 the harmonic balancer locating bolt is 6mm. The crank locking bolt is m10x1.5x33.55mm. I used a m10x1.5x40mm myself.
@@SimonM5 mistake side bolt is 38.55mm.
That little 6mm bolt is same as the timing cover bolts. That's what I used.
El pully lleva 74 # de torque y 90°para que funcionen las alanderas diamantizadas no de mas ni de menos
GREAT VIDEOS THANK YOU SO MUCH
Oscar Palacios y el torque esa polea no trae cuña,
Oscar Palacios pero me parece muy bien el video
This proceedure is not correct. Always lock the camshafts
to set timing yes. but to torque the bolt you do not want to lock the cams as the tool will definitely break the camshaft ends
Only if you remove the timing chain or loosen the sprockets. For this job, the pulley simply has to be aligned with the crankshaft sensor at TDC.
that cv axel is fucked up lol
what"s the simptom cranck pulley problem?
傳動軸襯套破了？
What size is the bolt on the crankshaft pulley 21mm or 22mm
21 mm size

Good
I want to hear how it ran after this.
Lmfao so do I
A foreigner?!
