today was freaking hot! perfect day to install the pulley on the cube, i got it since monday morning but the last couple days here were just cloudy and wet, ok
tools you will need:
flat screwdriver
19mm socket
big wratchet and long socket wrench
9/16 wrench
small wratchet with extension and a 10mm socket
jack and jack stands

start lifting the car and remove the front passenger wheel, after that put the jack stand rite next with the jack (safety is always a must)
-after that start by removing the quik snaps all around you wheel protector and a few ones under (just pry up with the flat screwdriver and they come off)
-once you finished with the quik snaps remove the couple 10mm screws that are holding the front part of the wheel protector
-after that move half way back the wheel protector and you will see the oem pulley along with the rest of the engine components

-next step is removing the belt, with the 9/16 wrench pull the tenssioner so the belt can loosen up and take the belt off, the tenssioner is rite on top the oem pulley with a hexagon shape

-the next step is to lossen the pulley, this can be done easily with an air gun but i dont have air tools at all and due to the size of the holes on the oem pulley you also cant use the pulley puller kit that you can loan at auto zone or pep boys so this is what i did to undo the bolt
with the use of the 5/8 wrench and a strong bolt trap the oem pulley so it cant rotate anymore see the pictures below

-unscrew the big bolt with the 19mm socket and the long bar, once you hear a pop it means the bolt got losse, take off the wrench that was holding the oem pulley and continue removing the big bolt
-dont panic if you see oil coming out of the bolt that holds the pulley it will be only a couple drops
-next with the flat screwdriver pry off the oem pulley, take your time and do it on a left&right sequence you will see the pulley will start to move around and soon it will come off

next you will have the chance to compare both pulleys, the nst and the oem together, you will notice rite away how heavy the oem is compared with the nst

-now you are ready to installthe new nst pulley
-use some of the oil that came off the big bolt and put some inside the nst pulley
-align the pulley with the engine shaft and pop it position just so it stays up there
-dont hit or slam the pulley to get it all way inside, instead used the big bolt again and tighten it little by little, you will see the pulley going in with no problem at all, once both pulley and bolt start to rotate together remove the bolt again just to make double sure that everything looks good in there

- after that procced to install the big bolt again and get it ready for a strong tight
-once you notice again the pulley rotates with the bolth when you tighten it do the wrench trick with the screw again and give it a good strong tight you will notice the engine will shift down a little bit as you tighten it for the last round (use a terry towel to wrap the wrench around the pulley so you dont scratch it when you tighten the bolt
-get the belt back on position and make sure the grooves meet the belt lines

and after that you are ready to go

reverse all the steps and put back the wheel protector back in place
from here and after is your own decision to just leave it as normal or cut a small window like me so you can see the pulley

remember! take your time and dont rush it, total time it took me just about one hour
no air tools and no pulley puller kit need it

Nice write up. Thanks for taking the time to do it.

 

[Bagged Cube]

nice tech article! any noticable difference with the NST pulley?

 

[NonStopTuning]

Very nice installation guide

Enjoy the new throttle response and the better fuel economy :yes:

 

[TrevorS]

Got any data to backup the improved fuel economy assertion?

We've seen improvements of 1-2 mpg when driving habits have remain unchanged. Weight reduction from the rotating assembly is very beneficial and noticeable on all engines.

Our thousands of Honda, Nissan, Toyota, Scion, etc. customers have also reported with their own experiences, confirming these claims over the past several years.

:yes:

 

[TrevorS]

Yes, I can believe a slight improvement with driving habit's unchanged -- however, I don't believe the typical purchaser of a lightweight pulley will not tend to goose the throttle a little more -- thereby not only negating any potential MPG benefit, but quite possibly observing a drop in MPG ! That's why I always say purchase a lightweight for the performance difference, not an improvement in MPG.

To each his own, right?!

The principle of weight reduction remains the same. Better performance and better efficiency when other factors remain unchanged. That's all I am trying to convey. What each driver does behind the wheel is out of my control.

:yes:

thanks for the comments
on a small side note:
most of the cars that me and my wife had own before, they never been intended to be a gas saver...sorry if just the true lol!
and sure im not a mechanich wizard or something like that, im just an honest car enthusiast
i been driving the cube all around today from san fernando valley to santa clarita back enjoying the nst pulley :yes:
truly i really like it, the more i do on this cube the more i like it and the nst pulley wasnt a step back at all, i do feel a good benefit from the pulley
less weight is automatically less gas spending (common sense) how much exactly i dont know
BUT I REALLY LIKE IT.... :yes: :yes: :yes: :yes:

I don't mean to hassle or contradict you, but I'm just pointing out that the typical enthusiast that installs a performance improvement tends to be inclined to engage/enjoy that improvement. That "enjoyment" behavior tends to negate any potential economy improvements that might otherwise be realized. "Common sense" doesn't necessarily predict that resultant behavior change.

The only way to know for sure is to actually calculate your gas mileage over a few fillups and see if you actually have gained MPG. If so, then you are clearly showing more restraint than many !


PS. Congrats on your new pulley. I had to get used to the increased engine noise when I installed mine, but my purpose was a boost in engine response, and it delivered perfectly !

Along with the replacing, did you have to change the size of the belt?

 

[damian666robin]

no, i used the same oem belt
you wont need a smaller belt since the diameter of the nst pulley is practically the same as the oem

OEM Nissan belt ;D
