Yoohoo belt broke again..
 

The first belt broke more like fell apart in less than an hour, Rob at pineapple gave me a new one (good guy will definitely be a return customer just not for the yoohoo belt). the last one lasted a few months, but blew the day after I advised someone of there mixed reviews (Karma). Same thing as last time fell apart. left green felt and rubber all over my engine bay. it also tore up the temp sensor wires from the radiator. need to redo the wiring now. witch I think caused my gauges to go bad (ground blew on the circuit board), and my red line buzzer witch has never gone off to go nuts and run constantly? So now I have no idiot lights, speedo, gas, tach, or anything else. nothing works. I think its fixable. I see the short. Sorry for the rant I just need to let it out to people who can feel my pain...

So I need to get a duel sleeved alt pully, I'm running 1 gator back belt now, and it hasn't slipped at all. I've tried. its good. My question is after all that ranting and raving is can I take two alt pulleys and make a duel sleeved one to save on moneys that I don't have.

respeed recently acquired some of the mistubishi dual pulleys and they are selling them for a very reasonable price, well worth saving the trouble of trying to fabricate something. If this is even possible, I think putting two stock pulleys together will space your grooves out too much.

Ditch the clutch fan. No need for any type of yoohoo or dual belt after you go electric fan.

Hmm, I have never had that happen to me. How are you putting it on? I know it is a tight fit, so I would recommend against using anything but your hands. I have heard of people using a screwdriver and making tears.

Even with the clutch fan, it was never necessary for me.

I never had any sorts of problems like this with my NAPA 3L220 lawnmower belt I was using as a yoohoo belt. Ran it like that for almost a year, then my friend gave me the alternator off of his FC that had a dual groove pulley on it. I think I had the clutch fan on it for a while, then I found a Fiero fan in the junkyard and ditched the clutch fan. It's sitting in a box in my garage somewhere. But when I installed it, I put it on like a bike chain, not using a screw driver. loop it around the crank pulley, put an edge up on the water pump pulley, and turn the engine over by hand. :dunno:

Exactly. You were fortunate enough to have a healthy clutch fan from the beginning.

On the engines that did require a yoohoo or a dual belt, the cause of slippage was the clutch fan dying. A simple clutch fan swap always cured it. Or an upgrade to an electric fan. :)

This sounds like what I'm experiencing with my Rotary Pickup. When I got it, someone had removed the air pump and the alt bet squeeled. I thought that by putting on a dual belt pulley would solve this. I put the dual belt pully on and got two matched belt. The belts havn't snapped, but it still squeels. It's driving me crazy. Could it be the cluch fan?

You can't beat the look and performance of a stock clutch fan driven by the dual pulley. The fan clutches are readily available on ebay or from forum members (Box_Man has one in his garage). Here's friend Mike's 85 GS:

And a recent video of the silver 85 GSL I just restored:

It actually found it's way back on to my car. Couldn't fit the Fiero fan onto my new short style aluminum radiator AND clear the water pump, so I had to go back to the stock dump truck fan.

All Hail the mighty stock Fan Clutch!

Yes, it is. My stock REPU unit died and started leaking. It squealed even with dual matched belts. I switched to electric and the squealing stopped. Then I swapped to a different clutch fan and a single belt. No squeals and I got to learn how to tell when a clutch fan is good or bad.

The belt I had on when it started squealing was in dire need of replacing. Still has not made a peep with the gaterback. fan clutch is good. I had a good belt that kept slipping off till it got damaged. then I put the one I had that was on it when I bought my car. had lots of cracks.

Got my gauges fixed today. so I now know how much gas I have, and how fast I'm going. I'm in the process of stripping the dash to bare metal so I can reinstall the gauges.

So If one belt works don't worry about it?

Ray, why is your rats nest still installed, If your not running a smog pump. do you just not run it unless your doing emissions?

Mostly I just like the stock look and keeping things original. Also I've experimented with removing the nest and stripping down the Nikki but I couldn't get nearly as good gas mileage with it that way (23-24 with the nest, 16-18 without it) and I didn't like the throttle progression without the nest.

And yes one belt, in good shape and properly adjusted, should work just fine, I had it that way for years. Having the double pulley is mostly for looks although it does give you a little insurance and longer belt wear.

My car runs pretty good with no rats nest and stripped nikki. I also have no shutter valve witch makes decell allot smoother, with one thump after I've been on the secondaries for a few seconds and let it wind back down. I'm not sure on the gas mileage though. when it was stock it would pop every shift, and decell sounded like a tiny machine gun. Even when I converted to direct fire

But yeah, I'm a fan of the bare Keg look. Makes maintence 100X easyer also.

I agree it looks great without the rats nest too and it's a whole lot easier to work on, especially removing the carb, which is a real pain with all the rats nest stuff on there. Here's a photo of mine back then, I was completely happy with the nice clean look

And more recently with the systems restored:

A close up of the stock fan clutch/dual pulley set up:

One thing is for sure, if you decide to keep the nikki support systems you need to be sure the components are functioning properly and you have to watch for vacuum leaks, which takes getting to know all those parts pretty well.

I never had any luck with the rats nest or any of it's associated crap. I had no vacuum leaks (Checked with propane), but the car still got 15mpg and was slow as hell. I removed it all (EVERYTHING, rats nest, airpump, cats, stripped carb, etc) and got somewhere around 19-20mpg and was notably faster. Maybe my solenoids were going bad or something. The new motor on the same setup gets around 24-25mpg with me driving it hard every chance I get, and feels as if it's making 1.5X more power than the old one.

When I first got it:

With the Fiero fan:

And as of about a week ago (it runs now) my somewhat current setup with my fatass radiator that is too thick to allow me to run my Fiero fan (too short too)

For anyone that has cooling problems, look into those ebay aluminum radiators. My car runs so cool with this thing it's amazing. When it's warming up you can put your hand on the bottom end tank, and burn your hand, then put it on the top end tank, and it will be cold. :)

And just to prove that dual belts, etc. are unnecessary, look at this IT7 car.

And I was relieved to see how small the rats nest in the rx-7 was after my previous car... Old honda rats nests are nightmareish.

:biggrin:

my belt slipped too until i went electric fan, my belt hasnt slipped since

Pretty! Worth the price of the dual pulley just for that look.

my belt slips like crazy...i always thought it was because I had my Air Pumped removed and that in turn created more stress for the single belt. Hmmm i was gonna do the dual pulley so that the damn belt would stop squealing but now that i read this it may not solve that issue. Ive had this issue before with the last engine too. I am envious of you guys running single belts with no squeal whatsoever....ENVIOUS I TELL YA!

Change your fan clutch or go electric and make sure your belt is tightened properly and that should be all you need.

I'm going electric in my FB. Might as well; I have the fan, the fan controller and a background in electronics. The old setup would squeal with the Camden and a clutch fan so I hope it will stop now.

Got my dash stripped to bare metal and painted black today. Got the gauges back in, and everything works. I'm not quite finished modding the dash. I'm taking parts of the lower part that bolt to the mounting points, for now its just in with the 3 bolts up top. I'm going to make it much easier to remove. belts still holding strong. I have it on pretty tight though.

is this that belt?

i just found this one on the napa website

Thanks Ray. :icon_tup:


And that should be the belt Marcello, the Napa belt is (when I bought mine) constructed like a regular car fan belt, so it's more stretchy and doesn't disintegrate like a standard fibrous green lawn mower belt.
