How To Install The Crankshaft Pulley For Mazdas
It will take you Approx. 30-45-min to install.

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.
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.

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.
Will this fit the 2012 Mazda 3 2.0L F non sky-active
No it will not
Will this fit the 1.5L version of Mazda 3?
We did not get the 1.5 here and are unable to confirm fitment.
Will this fit the CX-3 2.0 Skyactiv Engine?
Yes it will!
Will this fit 2017 mazda 3 hatch Grand Touring 2.5l?
Yes, it can be installed on the 2.5 motor.
So, I can't seem to "walk" the water pump belt off the OEM pulley in the way the instructions suggest... any pro tips? I have a 2014 M6 AT. I'm pulling downward with a shop towel, but not able to turn the pulley.
Use a ratchet on the main pulley and rotate it while pulling down on the belt just before the water pump pulley. That should do the trick.
I have seen that the crankshaft pulley can be installed in a 2013 skyactiv but which one should order the 2014+ model or the cx5 2013+ model
Send us a message or give us a call to confirm fitment. We will need to verify what you are driving.
Hey will this fit a non turbo 2018 mazda 6?
It has not been tested on that model yet, unfortunately. Stay tuned as it may be posted in the future.
Will this fit the Mazda CX-5 (KF) 2.0 SkyActiv-G 165 Spec ?
We never got a 2.0 in the KF body style here in the states so we have no way to confirm for sure.
Does this fit any of the Gen 4 Mz3 models like 2019 or 2020?
We have not yet tested, so at this time no it does not.
Will this work on a 2018 2.0 Mazda CX-5 KF
We have not tried so we cannot say for certain. However, if its the standard 2.5 G then it should be OK. We cannot guarantee it though.
Will this work on a 2017 2.0 mazda3
Yes
will this pulley cause wear and tear on my motor quicker? and is it ok to run it with the OEM motor mounts? i know the pros, but what are all the cons?
What guarantee for these item?
2 year warranty on the part itself. The warranty does not cover installation labor. The pulley comes with a warranty sheet to fill out.
do i need to do any programming modifications on the ECU after i add this pulley
You do not.
Does this only work on a manual transmission or does it also work for automatic transmission (2.0L/2.5L) engine for Mazda 3 2014+?
It works on both manual and automatic models.
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.
Will this part fit on the 2016 cx3 AWD?
Unfortunately, we have not gotten the chance to check it on the CX-3. However, it has the same engine as the rest, so it should fit. But no promises there.
I've just installed CS crank pulley. Do I need andy considerations before using it? Can I force it to 6000rpm (Drag race for example)
Yes you can.
Do you have seen the failed car that was fitted with a lightweight crank pulley shaft ?
We have not had any issue with our crank pulley.
We have not had any issue with our crank pulley.
We have not had any issue with our crank pulley.
how do you remove with a auto transmission if you don't have access to an air gun? as you cant just push the brake like you can in a manual transission
Have a buddy with an electric impact gun? 1/2 drive should do the trick.
That will get it off but how to I re-torque the bolt then?
If you don't have access to a torque wrench, you should be able to rent one from an auto parts store to make sure the bolt is torqued to spec.
Getting a torque wrench isn't the problem its the fact that since I can't keep the crankshaft from turning there is no way ill be able to torque check to see if it's between 55-80ft lbs
You will need to pull off the torque converter plate, and have someone hold the flywheel while you torque the bolt to spec.
Okay well I feel you need to implement some instructions for us who have an automatic for future people
Sam, Thank you so much for your feedback. I will make a note of the problem you are having so we can maybe implement future instructions!
Your welcome on the feedback and thank you for listening to your customers!
You are very welcome!
what do I use to hold the flywheel as the hole is small also my car doesnt have a cover plate, is it bad that one isnt there?
A pry bar should work. I would wrap it will a microfiber towel so you dont scratch anything holding the flywheel. Your car should have the plate.
Do I need to buy a new torque to yield bolt for installation?
John, You should be able to use the original bolt as long as it is still good.
Hi does this fit Mazda 5 2.0L engine? Year is 2014
Brian. Unfortunately, the pulley will not work with the Mazda 5.
Hello Team CorkSport, What is the diameter of this pulley?
Sonny, Should be the same as OEM.
Just curious. When I search Mazda 6 parts this doesn't show up. But under the mazda 3 page is says this part compatible with a mazda 6. Why doesn't it show up under the mazda 6 parts?
It will fit with the 2014+ Mazda 6.
Does this work for the 2.5L in the 2014 Mazda 6. BTW I love how the car handles with your springs:-)
Yes it does.
Will this cause an increase in wear on the engine (bearings, etc) since you're removing the factory harmonic balancer/dampener?
This will not cause anymore wear or tear on the factory bearings or parts of the engine.
Any point to purchase this for the automatic? Or will only for stick? Thanks!
Any reduction on the weight of the rotating mass will affect performance so yes you will get an improvement with an automatic model.
with this pulley not having a harmonic balancer and being lighter will it have a negative affect on the engines idle especially in a automatic as they idle at 500rpm
It should not affect the idle amount.
Would this part be recommended for an Automatic? Being that the new part is 68% lighter than the original, will this cause the computer to start coding?
It will work fine on an Automatic. I don't understand what you mean by "start coding". The ECU will safely run the car with the pulley added.
Does Mazda 3 come with 1 or 2 pulley?
The engine has 5 different pulleys all visible on the outside. There is only 1 Crank Pulley which is what this replaces.The rest are pulleys on accessory items, water pump, alternator, etc.
Can you guys make one for second gen. 2.0L? How come no love for second gen 2.0L? 2.0 in second gen I think is the same as first gen. so you would kill two birds with one stone ;)
There are limited amounts of 2.0L models in the second gen and even less people modifying them so we will not be designing one.
Will you be making one for the 2.3L or 2.5L 2010 models?
We are not planning one for the 2.3L or 2.5L models.
Is there any HP or torque gains from this?
By Lightening the crankshaft pulley you should have quicker response and better power. There isn't a specific HP gain.
Will this fit the 2013 mazda 3 skyactiv 2.0 ?
Yes. The 2.0L SkyActiv engine in the 2012-2013 will work with this.
Is this light weight pulley the same size as original pulley and is it balanced ?
They do not have a harmonic balancer, but they are made from billet aluminum and the diameter is the same so they should have no problems.
Does this have a built-in harmonic balancer (damper)?
They do not have a harmonic balancer, but they are made from billet aluminum and the diameter is the same so they should have no problems.
Will this fit on a standard 2.0L for a 2010 Mazda 3
It will NOT, it ONLY fits the SkyActiv engines.
I notice your answer about but the description says I fits the S models. Does it fit all 2013 Mazda 3 models?
It ONLY fits the SkyActiv engines.
Will this fit a 2012 mazda 3 Skyactiv or will you guys be making one?
The pulley will work on the 2012-2013 2.0 Skyactiv Mazda 3.
