Hello all,

Im going to be installing the NST Underdrive Crank Pulley soon by a performance shop, But i want to know if there is anything i need to know about this pulley that i should inform the installers about ?

Any information that i should know about like belt size or anything else i would greatly appreciate it.

Thank you


Review: <-- Better Throttle Acceleration, and i notice that it picks up harder in 1st and 2nd gear. This thing is one bad ___ mod , i recommend it to anyone. Here are some pictures http://www.cardomain.com/ride/1979954

 

NSTonAIM would be your best bet. They are very helpful and wont steer you wrong.

 

Everything you need to know can be found on their website. Check out the link bellow for some basic instructions you can take to your mechanic, the page also has the belt number that you are looking for.

[mrow:699735015b]Step 1 -

Jack up the right side of the car and place it on a jack stand for stability[mcol:699735015b][mrow:699735015b]Step 2 -

Remove Tire and look for plastic side panel....

-Remove two 10mm screws and one pop holder on the outside
-Remove two pop holders (One underneath and one up on the backside of the piece)
[mcol:699735015b][mrow:699735015b]Step 3 -

Picture of the piece removed
to the right of the picture, you'll see the two pop-holders that are a little harder to get (You can also see them in the last picture of the install[mcol:699735015b][mrow:699735015b]Step 4 -

Look at crank pulley and line up the notch on the pulley with something you can note...

I lined it up with a side of the bolt next to it (comes in handy later)
[mcol:699735015b][mrow:699735015b]Step 5 -

Use a 19MM socket and air gun to remove the bolt holding the crank pulley on

[mcol:699735015b][mrow:699735015b]Step 6 -

Look at crank pulley and stair bewildered at how hard the stupid bolt was to take off.

[mcol:699735015b][mrow:699735015b]Step 7 -

Locate the tensioner bolt and use the breaker bar to pull the tensioner assembly toward the front of the car, while pulling off the belt from the crank pulley down below

(Two People Are A Must For This)

[mcol:699735015b][mrow:699735015b]Step 8 -

Leave the Crank Pulley Alone for now and disconnect the positive lead to the battery using a 10 MM socket
[mcol:699735015b][mrow:699735015b]Step 9 -

Note the small cap on the bolt which needs to be removed to remove the wire (10MM)

Also remove the plug connection by squeezing it and pulling up.
[mcol:699735015b][mrow:699735015b]Step 10 -

Look at this pic of all the connections removed, also release the white clip on the front of the alternator

[mcol:699735015b][mrow:699735015b]Step 11 -

Remove the Alternator by first removing the 14mm bolt on the top rear, and then the 12mm bolt hidden under the pulley
[mcol:699735015b][mrow:699735015b]Step 12 -

Look at this pic of the wire assemble nut, the 14mm rear bolt and the 12mm front bolt.

[mcol:699735015b][mrow:699735015b]Step 13 -

WIGGLE WIGGLE WIGGLE the alternator out of it's holder.

[mcol:699735015b][mrow:699735015b]Step 14 -

Here's a pic of the Alternator with the stock pulley

[mcol:699735015b][mrow:699735015b]Step 15 -

To Ease the removal of the pulley bolt, we wrapped the pulley with a rag and used a 22mm socket and air gun to remove the nut.

[mcol:699735015b][mrow:699735015b]Step 16 -

Place the new alternator pully on and torque it down!

[mcol:699735015b][mrow:699735015b]Step 17 -

Stare amazed at the size difference and how light it is compared to stock

[mcol:699735015b][mrow:699735015b]Step 18 -

Locate the water pump pulley and remove the 4 12 mm bolts holding it on

(This is REALLY tough)

We used a small open ended 12mm wrench and put a flat head screwdriver as in the picture to hold the pulley in place.

LOTS OF ENERGY EXPENDED ON THIS STEP

Note - For Automatic tC's you will need to angle this correctly to get it out... but it is possible.

[mcol:699735015b][mrow:699735015b]Step 19 -

Look at the difference in pulleys and be amazed at the weight difference AGAIN!

[mcol:699735015b][mrow:699735015b]Step 20 -

Put the new pulley back on and tighten the for 12mm bolts down


IT'S HARD TO HOLD THE PULLEY IN PLACE!

[mcol:699735015b][mrow:699735015b]Step 21 -

Get your pulley removal tool READY for the CRANK PULLEY

(It's Scary Looking)

Put the outside hooks over the pulley edges and the loosen the middle screw to get them on, then tighten the screw and slowely pull the pulley off!

[mcol:699735015b][mrow:699735015b]Step 22 -

Stare Amazed AGAIN at the difference in size, and feel the weight difference!

[mcol:699735015b][mrow:699735015b]Step 23 -

Note to notch that MUST line up with the new pulley

[mcol:699735015b][mrow:699735015b]Step 24 -

Line the new pulley notch with your mentally noted mark and line it up correctly...

Use a nice rubber hammer, or block with hammer to knock that baby on.

Tighten it down to 110 ft/lbs

[mcol:699735015b][mrow:699735015b]Step 25 -

Slide the Alternator down into it's home and bolt it back down with the 14mm rear bolt and the 12mm bolt underneath... resnap in the cable harness and 10 mm bolt holding the wire to the top...

plug the wiring harness back in

[mcol:699735015b][mrow:699735015b]Step 26 -

Look at this nifty diagram to see how the belt goes on... it's really confusing....

Pull on the tensioner assembly again to pull the belt over the crank pulley

[mcol:699735015b][mrow:699735015b]Step 27 -

Check the belt to ensure it lines up and freely moves

Look for any weird tools in the engine bay!

[mcol:699735015b][mrow:699735015b]Step 28 -

Reattach the plastic piece and make sure to get the rear two pop-holders back in!

[mcol:699735015b][mrow:699735015b]Step 29 -

Replace your wheel and torque it down to spec.... lower your car off the jackstand and start it up to ensure the belt runs freely and doesn't squeak or move back and forth[mcol:699735015b]

LOL y didnt you just link they other thread?

 

I just got my Pulley installed about 1-2 hours ago.. here are some pictures http://www.cardomain.com/ride/1979954

This is a really nice mod, i recommend it to anyone who wants some nice decent gains.

 

why did you sell a celica with the trd action package for a tc


oh well nice looking car and some good choice in mods (swap the shifter pics around lol it shows the tall one as the short shifter and the little one as the crative compacts)

 

that celica was nice. but i think it was a smart move. lol the tC is a nicer car. (unless the celica was s gts...)

 

Dood i loved my celica, i was the only person in miami, hialeah with the 1st yellow celica, but it was my 1st car and it was automatic (GT) so it was slow as a cow, from a Celica GT to a Scion TC, (big difference in performance) so i had to let her go

 

I think the 747 belt NST recommends is the one ya need for crank/alternator/water pump pulley swap. The 750 is supposedly the right belt for just the crank pulley swap. After much struggling I was able to finally pry the 750 into place. However I decided it was the wrong belt and switched to a 755. I'm not sure about everyone else's experience though. The 750 may have worked for others...

 

well. i already have the 747 so ill just wait to install mine for when i get the other 2

 

They didnt have the 747, but they had the 750, and it works just fine.

2nd Day with the pulley and i notice a big difference in throttle acceleration, it picks up harder now.. im impressed with this pulley

 

I run the 747 for all the pulleys (all three) and it seems to work niftily.

 

im still on the fence about keeping my kit.........thanks for the write up, i was sitting staring at the engine bay for about 10 minutes trying to figure out how i was going to install this.......


do you see any negatives with running the pullies? have you had any issues at all?

 

DO IT Don't let the pulley haters scare you. No problems here.

 

Its my 3rd day with the pulley and on my way home from work , i punched it, and i noticed the difference. This pulley is a must have.

 

Did you guys all need the pulley removal tool to get the crank pulley off?

Is there anyway you can just pull hard on it to get it off?

Also, is it 110ft/lbs of torque for all lightweight pulley's or is that just for the NST one?

 

the webpage says there are two belt sizes - K060747 or K060750


which is the better of the 2?

 

that write up that was posted had some things that could be made easier, 1) i went to pepboys and got a serpentine belt tool, its waaaaaay eaiser to loosen the tensioner 2) pepboys also removed the alternator pulley for me which saved me time, that towel trick did not work for me.
I did not need a pulley remover to pull off my stock pulley it just pulled right off with some wiggling of it.

good luck.
you will love them, i do
