NOT IN THIS CASE...

 

Since this is still up does anyone still have the correct belt numbers for the Unorthodox Pulley? Mine are gonna get replaced cause they whine a little bit sometimes.

 

ALTERNATOR & A/C BELT:
GATES, Part# K060408
(41.5" or 1055mm) or
GATES, Part# K060410
(41" 5/8 or 1066mm)

POWER STEERING BELT:
GATES, Part# K040300
(30.75" or 780mm)

 

First feel the belts for excessive slack; they should be taunt, if not, try tightening down the tensioning screws first. If that doesn't fix it, replace belts with the ones ramberg listed.

 

And remember, keep a list of the belts in ur glvoe compartment in case one goes out on u on the road, or for the new owner when u sell ur car. Right???

 

Thats a great idea.

 

Thanks for the help guys!

Anyone know the size of the pulley bolt?

 

The pulley bolt is 19 mm. I tried but could not get it off. I cant seem to be able to hold the pulley still when I used the breaker bar. The lil mother is on there good. I also used an impact gun. Still, no go.

 

!@#%*~
Mine came off easy, Goodluck!

 

Are you sure about that? I just took the crank pulley bolt out of an 02 VQ3.5 and it is a RH thread.

This is from an 03 FSM

 

Very nice man

 

Per the instructions...put her in 5th gear and either have someone hold the brake, or wedge something in place to hold the brake for you.

 

So which way is it (loosen = counter-clockwise or clockwise)?

Hard to believe that we can't come to agreement on this one!

 

For removal of the pulley bolt, it is COUNTER clockwise like shown in the picture. See the black directional arrow for removal, it's going ths way =====>>>>>

 

Thanks...I thought some had reported the opposite in the 2004+ (not that it made sense...but you never know).

 

Its all good, glad I can help...

 

ok, so COUNTER clock wise to loosen. Il ltry and see.

 

Come on buddy, get that pulley on already.

 

Well? Did it work?
I am 99% sure it was counter-clockwise.

 

How long did it take you to do yours?

I talked to a local mechanic and he wanted $100 to change it.

Said it would take two to three shop hours. Two or more hours?

My only concern is getting the belt to the proper tightness.

Where is the belt tensioner located (no mention in the directions that came from UDP...very poor directions IMHO)?

Also, how tight should they be (how much deflection)?

The only thing I can think of is visually inspecting the current belts to see how much flex they have and attempt to mimic that when I put the new ones on.

BTW, I plan on taking pictures and writing up a how-to and posting here when it is all done, but it will probably be a while before I get to it.

 

[QUOTE=darrinps]How long did it take you to do yours?

I talked to a local mechanic and he wanted $100 to change it.

I paid about 75 dollars and it took less than a hour and have had no problems with it. Later Warren

 

About 1 hour at home, no power tools, but I do have a floor jack & jack stands The pulley came off by hand, no puller needed. The nut was'nt as hard as yours(Thank God!!) As far as tightness, for me its more a "Feel" thing. Try checking how tight your factory belt is before taking it off.
Keep us ipdated!

 

Thanks, and I'll get a report back when I do it, but it will be a while (want to wait on my wife to take a trip...no nagging about adding more "car parts" that way).

I'll probably install the Cattman RSB at that time too, and may pick up a short throw shifter between now and then. After that I'll probably find a dyno shop so we can get a (relatively...only UDP and POP charger) base line on a 2005 6 speed.

BTW, is it fairly obvious where the belt tightener is located?

Thanks again.

 

Yes, theres two belts to tighten. One from under the hood and one from under the car.

 

I cant seem to be able to get the bolt loosened from the pulley......ne suggestions?

 

if you have a stick put it into 5th gear and have someone press the brakes. If this doesn't work brace the pully with something by sticking a small rod or screwdriver through the pully and against the block.

it's a hard nut to crack but it will go. Just be patient. It took me less than an hour from start to finish.

Also what are people talking about leaking? Whats going to leak? What does a UR pulley have to do with an oil leak? I'm sorry but I don't understand where the hell this would come from and I've been working on cars for years. My shop has never seen this happen either.

John

 

Any Luck?????

 

nope...not working as of yet......if need be....i guess i am going to have to get my hands on a HIGH powered torque wrench and do it pro style

 

The crankshaft front oil seal uses the pulley for a sealing surface. If you do not change the seal when you change pulleys or are careless and damage the seal while swapping pulleys, you may end up with an oil leak.

 

I put a set of pulleys on my Mustang Cobra and couldn't tell any difference, other than my alternator would not work at idle. I'm pretty skeptical on this mod. Seems that if you underdrive enough to really make a hp difference, there would be problems with accessories not spinning fast enough.

There's a certain "junk science" element at work selling the lighter pulley theory...

Ever notice how most of the dyno charts out there showing gains from mods are from someone who has an agenda?

 

I don't know anything about the Mustang but on the 6th gen Maximas you have to put on different size belts when you install the pulley. Maybe you have to do the same thing on the Cobra. I have had no problems with any of my accessories. Warren

 

the belt is ok on the Cobra because the drive pulley is smaller, while one or more of the driven pulleys are smaller.

 

Although I hear you LOUD AND CLEAR (far too many bogus reports by those who have a vested interest in the product), in this case I believe it does help as evidenced by dyno runs done by those who had nothing to gain. The results show at least a 5 FWHP increase using the UDP.

I don't have time to look it up now, but someone did a test using a 3.5 Altima that should be a fairly good apples to apples comparison.

 

If your corbra is super charged, an underdrive crank pulley WILL NOT
GIVE YOU MORE POWER. You would be spinning your SC slower?

 

I just got mines installed toady........luv the difference. accelertates much faster .

 

I had the pulley bolt taken off by the shop that put in my springs. Ill try to loosen it tonight and see if I can finally get my UDP on. Ill keep ya'll posted.

 

I give up again!! I had someone apply the brake and I put it in 5th gear and I STILL can turn teh crank pulley. ARGH!!!!!

 

To bring this one back from the dead...
To remove the crank pulley bolt do we remove it the traditonal way, toward the front of the car?

 

From what I understand its left handed thread, that is clockwise to remove. Someone else back me up on this.
