How To Install The Crankshaft Pulley For Mazdas

It will take you 45 minutes to install your CorkSport Mazda crankshaft pulley with our easy-to-follow instructions.

I wouldn't say this is a "must have" modification, but you can definitely tell a difference coming up from idle that the engine is slightly more responsive. It seems to spool up just a tiny bit quicker but not a huge amount. It is noticeable though. A very well made piece as well.
This was one of my last bolt-on mods that I did to my Mazda 3. I was super impressed by this pulley upgrade. I immediately noticed significantly better throttle response and faster revs. I recommend replacing your belts while they're off to save yourself time in the future. Also, as others stated, an impact is a must, but at least Mazda made accessing the crank pulley super easy.
First tip to this mod: Impact gun. The breaker bar attempt cost me a day and kept me up far too late on a work night.

Other than that, belt removal and installation is relatively simple. This part is significantly lighter than the stock unit. Butt dyno recorded slightly better acceleration and the motor reacts a bit quicker to throttle inputs, especially from a stop. Unfortunately, the 2.0 is still slow, but a bit more fun to drive.
I've been looking at this for a while, but decided to pull the trigger when I had to replace my belt tensioner. My first drive with the new pulley was way better than I expected. After reading the reviews and talking to a few people I wasn't sure if I would notice anything, but the bottom end acceleration feels like it has a little life, finally. Not sure how this would do on an auto trans, but with my MT with the OV tune, short ram intake and the Corksport axle back exhaust it's definitely worth the $170.
Easy install and great quality, directions are pretty straight forward. Car responds better taking off which seems a bit less effort than before. I have about 5 Corksport parts on my car now and so far loving all of them.
Great lightweight design very easy to install. Very little on "gains" but can feel better throttle response
It's a light weight pulley. It's constructed well, very easy installation. I don't feel much gains from it. I'd say Very slight acceleration gain it's almost not even noticeable. Id say it's an expensive little part for such insignificant gains. What can you expect though, it's just a cool looking pulley.
First off, Corksport and the customer service is outstanding. I have most of the mods available for the 3rd gen Mazda 3.

The crank pulley has been on my radar for a while, my car has a tune and a throttle enhancement tune, That in combination with full bolt-ons. With all of that already done to my car, really brings out the potential in this crank pulley, the car revs slightly quicker which actually made a change in the tone of my exhaust that was noticeable.

The install is doable but it is a bear to remove the crank bolt, an impact is helpful, i had to heat the bolt and use a breaker bar with a heavy duty screw driver holding the pulley in place.

Tyler, from Georgia
Thanks CorkSport team for observing the ways to improve our Mazdas. I use several modes from them, which I find very useful. But in this particular case, I am not sure, the part as durable as it is said. My first concern is material it is made of. Where is this safety factor of 3.8 comes from? Stress concentrator driven? Obviously, the critical spot is at the interface, where the yield stress is at the highest level. But hey, we are talking about Aluminum + Steel. So I wouldn't look at the VM stress. I'd look at MAX shear stresses vs Shear ultimate value. And that one is lower that the yield even for heat treated to T6.
And of course that is just a pure static loading. But how about durability? Corrosion resistance on anodized Aluminum + Steel is not good. So you will have some corrosions issues with corresponding fatigue crack. Even on the soft 6061.
No, I wouldn't go with it unless it is done from Ti o it has some steel inserts. Or I would leave it as.
Love working with Corksport every step of the way. I recently installed this along with the Rear motor mount on my manual Mazda6 and I have to say it is a hell of a difference. ESPECIALLY if you car is already tuned. Both items only took about 20-30 minutes to install and the results were immediately more noticeable. The engine feels less restricted and revs up a little more freely. The throttle response also improved.

After install this will involve our engine mounting or NVH? Currently our Mazda3 Skyactiv have slightly vibrate when engine idle (mine idle at 700rpm) or make a full brake (20 to 0km/h) when acceleration, I'm sensitive with those vibrations if this can solve my problem (minimum vibration) that was a great choice for us.
