Hey guys, installed my pre-production pulley and install was a breeze! Everything was spot on. Made a couple hundred mile trip over turkey day and it seems my MPG definitely increased! With 2 adults, 3 kids and a load of educational books for the kids in the back of the car, I managed 34.5mpg! Not to shabby. More testing to come on my normal route to work and back.

Things that stood out immediately.
- Car revs much more freely
- 1st gear & a little in 2nd gear pull harder
- No issue with anything at all including ac

All in all a WIN for the product. Here is a quick how to guide... With the right tools you can install this bad boy in about 25 minutes.

Jack up the car & place jack stands under the car for safety

Next, take off the rim or hubcaps, whatever you have....
http://www.garage1217.com/SCIONXD/PULLEY/PULLEY2/2.jpg

Remove the two 10mm bolts holding on the inner plastic fender cover and pull it aside
http://www.garage1217.com/SCIONXD/PULLEY/PULLEY2/3.jpg

Loosen the tension on the belt. The XD has a mechanical tensioner system.

Wait for rain to stop.... DOH!!!!!
http://www.garage1217.com/SCIONXD/PULLEY/PULLEY2/6.jpg

Next, remove the crank pulley bolt. It is a 19mm. I recommend an impact gun in this case which makes it a snap. I was lucky and my pulley just slid right off.
http://www.garage1217.com/SCIONXD/PULLEY/PULLEY2/7.jpg

Have a gear puller set on hand in case the pulley does not just slide off... which it most likley will not "I was lucky"
http://www.garage1217.com/SCIONXD/PULLEY/PULLEY2/8.jpg

Put new pulley in place. Chances are it will not just slide on as NST pulleys are TIGHT tolerance. Make sure the keyway is lined up with the key inside the pulley.
http://www.garage1217.com/SCIONXD/PULLEY/PULLEY2/9.jpg

Tighten the crank bolt by hand with a socket wrench which will draw the pulley over the shaft and in place. The torque to spec... I did not have the proper torque spec with me so I used the German "goodntight" method.
http://www.garage1217.com/SCIONXD/PULLEY/PULLEY2/10.jpg

Last, slap the belt back on & re-tension it. Take her for a test drive and SMILE!

Great product guys. I highly recommend it!

TWO THUMBS UP TO GARAGE1217!

pulley is on! started it up and took it around the block. fairly noticeable difference in 1st and 2nd gear, and the shifting seems a lot smoother between all gears, especially when downshifting because the engine matches its rpms better with less rotating mass. no difference in any accessories from what i can tell, but i havent thrown the AC on yet because its snowing a little now. i dont expect any difference though.

i also noticed that when i shift at lower rpms, i get more popping and whatnot from my exhaust. i like it.

all in all, its the same kind of benefit you get from the SSK, making your car that much more fun to drive (and you do get a little stronger pull in 1st and 2nd). a must have!

http://i10.photobucket.com/albums/a149/mrtheandrew/aDSCN0335.jpg

also, i thought i would try and write up some tips for those with questions about the install:

1. the splash guard is held on by 5 bolts/screws. save yourself the heartache of having it in your way and take it all the way off instead of just removing 2 or 3 screws bending it out of the way. its just as easy to put back on.

2. most important tip probably, you are going to need a STRONG impact wrench. im sure it varies some from car to car, but a 250ftlb wrench wasnt coming close to moving that thing. i used a 550ftlb wrench from home depot at 90psi (the max suggested) and it was able to break it free after a few seconds.

3. you will notice that the inside wall of the wheel well comes low enough to get in the way of your impact wrench getting a good bite on the bolt. be careful not to put it on there at an angle or you could strip the bolt. this didnt work for me, but you could try putting an extension on the wrench to give you room to work with. in my case, the joints between the gun, extension, and sockets absorbed too much of the 'impact' from the wrench to break it free. do what you can to use just the wrench with the socket on it.

4. moving the alt can be a pain. you will see the two bolts on top that youll want to loosen to let it slide fore and aft... but the process would be a lot easier if you could loosen the bolt below the alt. i didnt have any luck getting it loose, there is not much room down there to get a wrench on it also. nonetheless, you can still move the alt once you loosen the tension assembly bolts with a rubber mallet/block of wood method.

5. after youve got the pulley on, tightening that bolt to 140ftlb can be a pain because its hard to hold that pulley still. the best thing if you cant get a torque wrench to work is to dial your impact gun down some and put it on that way. i put my weak impact gun (250ftlb) on and turned the air pressure down a little. this bolt isnt responsible for turning the pulley (that is the key/keyways job) - it just keeps the pulley from sliding off the end of the crank.

6. belt tension - looks like the spec was posted on the previous page, but you need to move the alt about a half inch or so more forward than stock to make up for the slightly smaller pulley. you may even think to yourself that you are about to max the tension out, but you wont, so keep tapping with that mallet until the belt is taught.

i cant think of anything else at the moment, but those are the 'hiccups' that i ran into. it took me about 2 hours to get it on, but that includes putting the car back together halfway through and running to the store for a new impact wrench. i could probably do it again in 30min tops, so dont let this install scare you.

I'm thinking of purchasing this product. Nice tips pickledchang. So, How tight should the belt be? Should it be real tight as in no slack whatsoever when pushing on the belt after install or should have some slack. If needs some slack, how much slack when pushing on the belt? Will it cause any damgages to any part if the wrong tension is installed.

Would like to know what is the correct tension so I can DIY this baby.
Thanks for all the info.

.

The tension should be the same as with the OEM setup. You should take a look at your belt, perhaps press down on it, and get a feel for how much tension there is. You would also want to pay attention to the way your belt sounds with your OEM setup, so that can you can compare after your NST install.

After installing your new pulley, you should apply tension and get a similar feel when applying pressure to the belt. There will be no negative effects if you apply the incorrect amount of pressure. You just may need to make an adjustment or two.

You would want to start the car after your installation is complete and listen to your car. If your belt sounds the same while spinning as it did before your pulley install, then you are good to go!

The worst thing that could happen would be that you may break a belt prematurely, in which case you would need to spend a whole $12 on a new belt!!!

According to the xD technical manual the deflection is 7.5 to 8.0 mm for a new belt or 8.0 to 10.0 mm for a used belt. You check it at the mid point of the belt up and away from the air conditioner pulley. The crankshaft pulley nut is to be torqued to 140 ft lbs.

is that oil on the OE pulley?

pickledchang

03-11-2009, 03:35 AM

is that oil on the OE pulley?

yes, it comes from the bearing seal behind the pulley. when you pull the bolt off, it leaks out a little bit.

Well I got mine installed and am very pleased. Over all it was a fairly easy install. I would say that it was easier than installing a Fujita CAI but the main thing was having the right tools. A impact gun is a must, but other than that it was super easy. A special thanks to Non-Stop Tunning for seeing this project to the end and hopefully we will see a few more performance parts for the xD from NST.

i just got mine installed today and i was able to do it with a craftsman electric impact wrench rated at 250 lbs. and the pulley slid right off so it was pretty simple to do. review will come later.

maybe... ive had mine since march of 08, 14k miles.

have any of you noticed how much smoother downshifting is? the engine braking is a little weaker, not that its a bad thing or that bugs me. ill be real curious when the mpg reports start coming in.

03-12-2009, 05:02 AM

Has anyone needed a gear puller (as mentioned in the initial installation guide), or had any problems getting the pulley off AFTER the bolt is off? I'm thinking about giving this a try with my elec impact wrench (claims 250 ft-lbs). If it doesn't work, I'll have to wait until next weekend ( :( ) when I can get to a friend's garage and borrow a bigger air impact!
Either way, I'm very excited to get this on soon... :D

03-12-2009, 07:38 PM

andy, i did not need a puller at all. the pulley slides right off. the shaft it sits on is not tapered, so its not wedged on or anything. and you might be one of the lucky ones to be able to get it off with a 250lb electric. maybe the electrics apply the force differently from air and thats why i needed a higher rated air impact. i dunno.

Andyman

03-12-2009, 08:33 PM

Thanks Pickle! Good to know. The main reason I was going to wait and use my buddy's garage is that he has a gear puller set... (and the bigger air impact!) But I might see if I can give it a go before then. I'll definitely report back!

None... Had to wobble from side to side a bit, but it slid off by hand. No gear puller needed. Mine is an 08, bought early in the release with about 20K on it.

Got mine on! Very nice - I'm liking it. As for feel, I don't notice a huge difference in acceleration or low-end "pull", but there might be some there. I didn't quantify anything before/after. I DO notice less engine braking - i.e. when I leave the car in gear and take my foot off the gas, it coasts smoother and farther. It also seems to shift a little easier - well, not "shift" per se, but the engine seems to re-engage more smoothly as I release the clutch. Does that make sense? A little hard to describe. Between that and the NST SS bushings, though, shifting overall feels a lot nicer than it did new! :D

Overall, installation went quite easily. The pulley came off with my electric impact (el cheapo (http://www.harborfreight.com/cpi/ctaf/displayitem.taf?Itemnumber=45252), rated at 240 ft-lbs). It had to hammer for a few seconds, but then it spun right off. I used a deep imact socket (http://www.harborfreight.com/cpi/ctaf/displayitem.taf?Itemnumber=7383), which fit under the wheel well just fine. I would recommend one of these - I definitely couldn't have gotten a secure bite on the bolt with a standard (shallow) socket. To put the bolt back on, I just let the impact hammer a "few" times - my torque wrench just spun the pulley.
Other thoughts on installation -
1. The black plastic splash guards are annoying. If you have a socket adapter (http://www.leevalley.com/wood/page.aspx?c=2&p=44490&cat=1,180,42334) for your cordless drill, I highly recommend dropping a 10mm socket on there - much quicker than turning those little bolts by hand.
2. Moving the alternator BACK to loosen the belt was probably the hardest part for me. When I loosened the tensioning bolt, the bolt just came out - it didn't actually push the alt back. So I ended up tapping it back bit by bit with a dead-blow mallet - minor PITA. Re-tightening the belt was no problem - tightening the tension bolt with a ratchet snugged it up just fine. Don't forget the second bolt - just under the long tensioning one. :eyebrow:
3. Removing the stock pulley (after I had the bolt out) was a little tougher than I thought - it didn't just slide right off. I had to wiggle it little bits at a time, and get it at just the right angle, and it eventually came off by hand.
4. Getting the new one on wasn't too bad - carefully line up the keyway slot, start it by hand, and tap it on gently with a dead-blow mallet. This seated it just fine, and then it was just a matter of re-assembling everything.

Thanks to NST for a great accessory to give me a smoother, more efficient car! Looking forward to watching the mileage! (I'm already considering doing this on my Vibe... :) )

I installed my pulley this weekend. Very smooth install as well. My only concern is the torque on the pulley bolt. Once I got it to a certain torque the pulley would spin and there is no easy way of holding the pulley stationery to get a good torque on it. I am keeping my fingers crossed that I got it tight enough. Great product and great DIY thread. Thanks!

YES! Weight reduction leads to noticeable improvements in throttle response, acceleration, and MPG whether used with a manual or auto trans.

We have a very large number of customers who use our pulley kits on automatic cars. We have a few of these pulleys in stock and ready for immediate shipping if you're interested.

I have one on my auto trans and am very pleased. The biggest difference is in the fuel economy. Per the cars computer, I am averaging about 1.5-2 MPG better per tank. This is based on 75% highway miles but still. The pulley will pay for itself in less than a year.

not sure if this will help, but make sure if your impact isn't above the 300ft lb. area to not use an extension when trying to remove the bolt, thats what worked for me. you'll need a deepwell to get on the bolt, just keep trying, may come off after a few tries.

Just wanted to share - I was so pleased with the NST pulley on my xD that I bought one for my 03 Vibe (5spd man). Just got it installed this weekend, and it's great! Feels like slightly quicker throttle response and smoother shifts, especially on the low end, and less engine drag when coasting in gear in all ranges. Thanks, NST! Keep up the good work!

Well the install seems pretty easy, but I cannot get the crank bolt off. I borrowed my brothers electric impact gun that he uses at his body shop. I dont know what its rated for but he said it was $150 so I thought it would be up to the challange. I guess I gotta wait another week to get this thing on.

as cobaltbravo said, you are going to want a STRONG impact wrench. my 250lb wouldnt budge it, had to switch to the 550lb, which took a few tries. this was a pneumatic type. also make sure you are not using an extension, it will take the "impact" out of the impact gun. as stated, you will probably have to use a deep socket if the wheel well is getting in the way.

05-05-2009, 05:27 PM

I might try again today. My brother told me a couple tricks to use. Im not using an extension. My parents have all the tools I need up at their house. If I cant get it in I will be making a trip up there. It just sucks having this pulley sitting around for two weeks staring at me instead of in my car.

I just looked the impact gun up online, its only rated for 150 ftlbs so there is my problem. I wont even bother trying it again today and will just wait for the weekend.

I did my replacement on Saturday. Took the plastic cover way down and did not need to remove it to complete the task. I got the Pulley Bolt off using an electric impact tool. Was a breeze. The pulley removal from the shaft required a damper pulley puller ($18 from Napa) to remove it but that, too was easy. The clearance in the fenderwell was JUST ENOUGH to use the puller to remove the pulley. The engine had to be turned to allow the puller to clear. It was EASILY turned by hand to set the shaft angle to facilitate the removal. All the rest was just plain simple.

I gained 3MPG using the cheapest gas anyone can find. I truly have the CHEAPEST gas anywhere. I can't explain, so just take my word. You should have better results.

I'm happy to hear your positive review, and glad that you have noticed a positive gain with your new NST Pulley! Thanks again for the help and support of our brand, I certainly do appreciate it.

We have only a few of these pieces in stock now, and once they are gone this item may not be available again for some time.
