Went to my friends shop yesterday and there's a special bolt holder for the bolt that's on the crank that we had to use to take it off. Glad I went to his shop before trying to do it myself at home. And also in the instructions it said to turn the bolt 60 degrees without turning the pulley at the same time. We tried to do it by hand but the pulley kept on moving even when wedge something in the holes to keep it still. So, we marked a spot and used the torque wrench instead which worked. I have 20's on my car now so I don't know if I'm going to feel any real difference with the pulley on now compared to if I was still on stock wheels. Hopefully I feel some sort of difference and I'll let ya'll know.

they say that you need to wait about a week or so to reach full HP potential...im not sure where i heard that but im pretty sure, they said that the engine and the rhythm of everything needs to take time or something...PeterUbers? any input


also.....did u take off the Crank Pulley? if so...why? also...what is that worst that could happen with a lighter UR Crank Pulley? the harmonic imbalance...how does that affect the engine?

Usalinh

Yes, the factory crank pulley was taken off so I could put on the UR Crank Pulley. From what I heard changing out the crank pulley doesn't affect the harmonic balancer. Haven't heard anything major happen yet.

sorry USALINH, that question was for PeterUbers because he said he had the crank pulley for 15k miles or so....i was wondering why he took it off.

special-ed

I thought the additional duties of the crank pulley was to be the harmonic balancer ....which is basically a weighted damper to negate/counter-act against vibrations on a rotating shaft? Do our cars have a separate crank pulley and a additional damper (harmonic balancer) or are they both integrated into the 1 single pulley?

NFLblitze1

from what ive heard...and researched the UR Crank Pulley dosn't have a harmonic balancer.....and the stock one does.

encrypted03

I beleive that our engines are internally balanced, similarly to my 3.5 altima I had. I had a pulley on that for for about 3 years, and no problems AT ALL.

Usalinh

I'm with ENCRYPTED on that one. I'm pretty sure if the pulley worked as a harmonic balancer in anyway UR wouldn't release it unless they're sure it won't cause a lawsuit against them in anway. But, from what I heard also that most new imports now a days don't use it as a harmonic balancer.

I took the pulley off b/c I had gone through another tranny, and decided to bring up the lemon law on Acura to sell my car back to Acura (won the suit). So that's why I went back to stock... otherwise, i would have just kept it.

Also, once the pulley is on.. you "feel" the results immediately ... all this BS about having to wait until the ECU remaps itself or the engine gets used to it is .. garbage. I felt the difference as soon as I installed it, case closed.

i love this,more people that dont know enought about how a motor works
pullies suc
there is a reason pullies spin at a certain speed!
can you guess why?
i want to see who is smart here
any takers?
yes it will add power but with anything theres a drawback
lets see how long i have to wait for the correct answer ,lol

Honda does not use harmonic balancers on their crank pulleys.

I finally got my Pulley today! thanks Excelerate... i also bought the Gates belt and will attempt the install tomorrow. I'll keep you guys updated!

Good luck getting the bolt loose. I had no luck. If you get it loose let me know how you did it! thanks

MugenR

omfg! I hate this.. i can't get the f'n bolt off!!! i PB'd it for awhile... i used some pretty powerful 1/2" impact wrenches.... tried 3 of them... and also broke a snap-on wrench with a breaker bar... I BROKE IT!!!!!! the SNAP-ON WRENCH snapped in half!!!! this is insane.. i'll try it again later.. just gotta find someone with a 3/4" impact wrench.

Its sucks doesnt it! I am going to try that Jack method. It looks like it will work because your have my guess about 1000 pounds of pressure on that bolt. I am going to try that tonight hopefully.

MugenR

One question for you guys... what did you torque the bolt back on to? the instructions sheet says 47ft/lbs.... doesn't that seem a little loose? considering that i can't get the stock bolt off with 1000ft/lbs impact gun?

and also the 6thgen V6 accord and 2nd gen TL's instruction sheet says to torque it to 181ft/lbs....

can anyone explain?
thanks

It is 181 ft-lbs (well, actually I know for sure it's in the 180 range; I seem to recall 183, but it's close enough to 181 ) for the crank pulley.

47 ft-lbs was for the alternator, and the power steering pulley was even less.

The best way to do it is to take it to a shop and have them loosen the crank bolt; drive home and swap out the pulleys. Tighten as hard as you can, then take it back to a shop to have them torque it to the proper specification. My buddy knew the manager at a local Tuffy's, so they loosened and tightened the bolts for me, and I slipped the guy a fiver for the trouble. The air gun we were using just wasn't powerful enough.

When you take it to a shop, you won't have to jack up the car or anything to get to the crank pulley bolt. I know this for sure on the 2G, and I'm guessing it's the same on the 3G. In the passenger side front wheelwell, when you turn the steering wheel all the way to the right, there's a hole where you can access the crank bolt pulley through the plastic lining without having to take anything off.

Good luck.

MugenR

strange.. on my Crank Pulley install sheet it says 47ft/lbs.... i called UR and they didn't know... they had 47ft/lbs too on their sheet. they told me to call acura! how can they sell a product when they don't even know... i asked them if it could possibly be a typo and they patched me through 3 people before they told me to call acura.... wtf!

NFLblitze1

well its always good to be safe.....why not just call acura tommorow? better yet...e-mail them...youll probably get a faster response

jdm_98r

torque specs are pretty useless on crank bolt. Just turn up your impact wrech and shoot away. Now, if we were talking about your head. That would be a totally different story.

BTW... Did you get the bolt off?

MugenR

really? so i don't need to torque it to specs? just tighten with the gun?


no not yet.. i spent the better part of today trying to find a 3/4" gun... my friend at discount tire (General Manager) has one so i will pick it up from him in the morning and try it. I'm crossing my fingers, but he tells me it should be powerful enough... he uses it to take off box truck and mobile home bolts that are torqued around 450-500 ft/lbs.

jdm_98r

you don't even need to take the gun home. just have them loosen it up @ the shop and tighten it back on. it's usually just hard to get it off the first time. once you get it home you should be able to get it right off.

Well I finally go the bolt loose. I am making anothe post for you all to read.

jdm_98r

You must be one really smart cookie.

1. Accessory spin @ a certain speed, because they operate @ optimal performance @ certain speeds.

2. Most of the people doing this upgrade are using UR pullies. UR pullies are by far some of the best pullies on the market. Their underdrive pullies are not too small where it hinders the performance of the accessories. If you're really worried about underdriving the accessories, UR offers the "Ultra Sc" version which retains the same diameter as stock, but is still made from the same high quality lighter weight billet alluminum.

3. Quit being such a prick. There are always people around that will be smarter than you.

i got it install finally... even with a 3/4" gun the f'n bolt was stubborn, but finally came off! install after that took around 20 min... the belt was pretty tight. in all.. throttle response is SOOOOOO MUCH better.... low end torque is ok, mid range has improved greatly. and top end definatley has got more grunt. idle is quieter for some reason. no odd vibrations. It revs alot faster as well. all in all.. great mod! worth it other than the stupid stubborn bolt

blktl1

I agree probably one of the best mods you can do right know for the TL for quick HP and Throttle Response.

jdm_98r

congrats to you two on the DYI.

Can any of the moderators please explain to me why this person has not been banned from this site yet???

MugenR

thanks! it wasn't too hard after i got the bolt loose.

stavebomb

With the pully installed can you feel a torque gain?

MugenR

DEFINATLEY!

ejn184

just finish install the pulley. its increase the torque...

Lokius

how do you guys feel about it on the automatics? worth it?

MugenR

definatley worth it fitz

flvol77

BTW- I have the service manual and its says to tighten bolt to 47lbf ft.....that is kinda interesting. Maybe that is why the people at UR say 47? I don't know much about the UR pulley....I am still trying to figure out if this is a mod I want to do.

Would a dayco belt, part #5060820 work fine for the 04 TL? Is it any less good than a napa/gates belt?
Thanks!
Mike

Does anyone have pictures after the install?

againstallodds1

I just installed it yesterday, and I used an dayco belt and it worked fine. Now here is where my problem lays, after installation I took it out with a stop watch, and clocked it 0-60 before and after pulley. Same times no difference right away. The instructions say that it takes 5 to 7 days for the ECU to adjust. My 0-60 times were ( with 5AT) before aem cai first run 7.5, second run 7.3 after cai first run 6.6 second run 6.4 and after install of pulley same time. This is immediatley after installation. all these runs are with 2 people in the car, so they are faster without all the weight. About an hour later I was driving home and I noticed an increase of power. And in front of me was a mustang gt about 03, with straight pipes coming out the back. I passed him on a double line and got in front of him. He pulled up on my tail, and I hit it. The whole way down the street I was pulling on him. I was definately faster, I couldnt believe it! So right now I am going to do my 0-60 time run and I will post the times with only me in the car. And yes dayco belts will work.
