Underdrive Pulleys

[lilchubbz05]

Alright yesterday i decided to try an throw on my UR pullies. So i proceed to tear the car apart so i figure, shit this is easy. I get to the crank pulley and FUCK. I tryed everyway i could think of to get that bytch loose and nothing.I was using an impact gun and it was doing nothing. i even welded myself together sum ghetto ass tool to hold the pulley while another friend cranked on tha nut......it bent the fucking tool...awesome. well after three hours of working on the crank pulley alone i gave up and put everything back together....waste of a day. NEWAY....does anybody have any idea how to get it off?? or has anyone done this before?? IM clueless on how to get it off and i need help asap. thank you in advance..ne advice would b greatly appreciated.

Don't most under drive pulleys go on the accesories? NOT the crank? That would seem alot easier to me... And what you need for that? One big ass 1/2" impact gun and at least 125 PSI to drive it.

so those bolts are right-hand threaded or left-hand threaded. b/c i know in some situations it's better to use left-hand threaded so the thing will only tighten but not loosen under use, depending on the situation.

I know this to be untrue. I have an Unorthodox crank pulley and AEM accessory pullies as well.

lilchubbz05, if you can take you car to a "shop" and have them lossen the pulley for you, that may help. Just have them "snug" the bolt back on so you can drive home. Make sure to tip the mechanic for his time though... a couple of bucks is worth the hassle. Also, there is a tool availible from Snap-on that attaches to a 1/2 breaker bar. this is designed to hold the crank pulley while anothe breaker bar is used to loosen the bolt. I believe the tool is about $50. It is expensive, but then you will always have the tool... so you can charge your friends rental fees to loan it to them.

thanks alot 2point6. I just went and got the tool and will try it out this weekend when i find time. ive heard mixed opinions so far, whut do u think of them??

[f22-dohc]

not sure if this will help

my buddy put his 2.5 rs into 5th gear and used a breaker bar....voila. done

then again, ours is diff

fyi---> after a few other mods, inluding stage 2 ecu tune, it made a HUUUUUGE diff.......

Heat? Impact wrenches? your poor cranks and seals, lol. The tool that 2point6 mentioned is the only way to in my opinion if you don't have any way to lock the flywheel/flexplate from moving. Even with the tool sometimes you need to people to break it loss.

[lilchubbz05]

ON and im so damn happy....IMO it help more than the anything else so far(i/h/e). it waz worth every penny and i recommend them to ne1. I finally decided just to take the car to a dealer to loosen the crank pulley because my impact gun waznt strong enuff. ooo.....the instructions that UR gives you for belt sizes are wrong...i used Gates K050410 and K040413....should help u save some headaches and money. no dynos that i know of in iowa so i will just show pictures until i can get to a track. ALso i took off the header thanx 2 sum helpful advice.

I run the AEM pulleys on the accessories and I use an Unorthodox crank pulley as well. I think they work great. I don't have a stereo system though so I don't worry about voltage issues.

What size belts is everybody using? I've got the crank pulley, but will be keeping the stock accessory pulleys. Should I still use the same numbers Gates belts everybody else is using?

sorry to bring thin thread from the died, but hey, thats why we use search.

i have the same questions as ^

im just gona use the stock acess. pulleys and use the unorthodox crank pulley, so couldnt i still be able to use the same (stock) belts?

thanks

You may need a different belt. The adjuster may not be able to take the slack up of the smaller crank pulley. You'll probably need a belt a half an inch shorter.

[theone]

ok, cause i just check the autozone to see if they carry the belt the guy at the top of the thread suggested, and they do.
long as its not hard to find one
