Ok, is there some special trick to getting the yoohoo belt on? I ordered mine from Pineapple Racing and I can not get it on straight for the life of me. Everytime I get it on it flips around so while I spin the main pully it spins around. Then I can't get it off so I have to take off the main pully too. Now I have to go through the hassle of getting my timing mark straight again which means I'll have to check out my flywheel because I was too frustrated to remember where it was when I pulled it off.

 

I used a screw driver to set it on straight. when I got the belt on it always flipped on me, so I put a flat head on the belt and spun the pully and it sat itself nicely.

 

Let me know how it runs for you, I believe it was the cause of my alternator belt squealing and eventually snapping. I got a new belt on now, and its been 2 weeks. The squeal is back...

 

Is this the same belt as the mower belt?

 

Yes, 3L220:

 

This is how I did it, I put a flat head screwdriver on the red part and rotate it in the blue direction

 

Dang it Stu, I thought I told you to get that belt off, and go with the double alt pulley. BTW, how's the car running now?

 

I need one, cause I took off my air pump... No Im not driving the car.

 

I will give you mine when I get that dual alternator pully if you like. It has maybe 250 miles on it.

 

Thats really nice of you, but instead of going though the hassle of paying shipping id rather just go to a mower shop and buy one.


Unless you paying the shipping hahhaa.

 

It's not a 3L220. That was the original Yoohoo Belt. The new one (green one) is a different size, which we found to work better and more consistently.

We shot a how-to video on installing the belt but I haven't gotten around to finishing the editing. There are a couple tricks to getting it on right. The first is to remove one of the pulley bolts on the main pulley, so the belt can slide over that area without catching. The second is to use a hook tool, which will catch the belt on the pulley and walk it around as you turn the engine over with a 19mm socket. And finally, when the belt falls into the pulley groove it almost always has a half-twist. What you do is rotate the engine back a bit (~1/4 rotation) and then forward again, which gets the belt to turn over correctly. Harder to explain than to do but it works like a charm every time. I will try to get the video posted in the next week or so.

BTW, the new belt is intended to fit very snuggly. Don't worry about this. The belt will wear-in. The old 3L220s we used to use were hit or miss whether they would fit properly due to variance in their length (actual vs. nominal). You would have to buy three or four and try them one at a time, then return the ones that were too long or too short. This one fits snug no matter what, but not too snug thanks to a little give in the construction.

 

That would not be very smart. Not only is it more expensive but it doesn't work as well. You end up with less pulley contact area, stress your accessory bearings and one belt will always be too loose or too tight. Even "matched" belts will not be truly matched because of deflection. And, if one belt breaks, it almost invariably takes out the other belt! With a Yoohoo belt, a broken alternator belt virtually never affects it, leaving you with a working water pump, so you can at least drive to the next freeway exit or gas station instead of being stranded or risk overheating your motor.

We have been advocating Yoohoo Belts for over 20 years but ignorance is hard to overcome when dual alt pulleys look so cool.

 

How well does this new belt work? I used one of the black ones like 5 years ago on an FC of mine and it snapped right away. I dont think it was on there for 3 days.

 

No offence, I got my yoohoo belt from you and it caused my first alternator belt to snap, and got a new belt. Same symptoms are occurring... is there anything I can do to help it? I just dont want to buy a new belt every month.

 

the yoo hoo belt would have nothing to do with snapping your alt belt... that's a little bit of a low-blow to say something like that... blake's a great guy and pineapple has some great products and INCEDIBLE support... I've been running one of his yoo ho belts for wel over a year with absolutely NO problems. If you're going through belts like that, likely its a nick in your alt pulley or the alignment is off. I experienced the same problems with my old 55a alt. But after replacing it with a Delco CS-130 105 amp and new pulley, I've had ZERO problems.

What I'm getting at is don't be so quick to blame, think logically and TROUBLESHOOT your problems.

 

I am not trying to play the blaming game here. I am just stating. Nothing went wrong when I had the air pump on, took it off and put the yoohoo belt on and belts are squealing. I have a different alternator, but I checked it for nicks or any problems, and nothing arises. I know PR puts out good products and I am not slamming them, I just wanted some insight to my problem.

 

Check the alignment of the alternator pulley vs the main pulley, you may have to adjust the alternator position some. The alternator bracket can and will flex to allow repositioning of the vertical plane of the pulley.

 

I looked at it, and it seems to be straight on. Is there a way I can check it for specific degrees? I have a level here, I will probably use the block as reference and adjust the alt to where it should be, if it is out of spec. Its weird, the belt was fine and everything was great, then a week later it would start up. Must be wearing it down?

 

use a staright edga and place in the groove of the alt pulley and the main and waterpump pulleys.... this will show you if it's lined up.... even being off a few mm can cause your belts to desintegarte pretty quickly... also don't over tighten the belt , should have about 1/2" of play/deflection...

 

Gonna go check it in a few. I was worried that if it isnt my alternator, then it could be my water pump. The yoohoo belt has zero play in it even after some miles on it, and I wonder if that could be too tight and pulling the pully down a mm or two.

 

Tried for another 2 hours today, even had a friend help. Tried with one screwdriver and almost got it on with two of em. Still no go, I'll have to try again tomorrow since I work the rest of today, I'm starting to think I should have just left my air pump on and use the stock belt.

 

Dont get down on us now! When you get it on, you will see that it is worth it.

 

Or, gut the air pump, reinstall it and use the old belt!

 

"Or, gut the air pump, reinstall it and use the old belt!"

I did this, it worked!

Still, I think dual pulley is the way to go:

Well I just wanted to let you guys know that I finally got that belt yesterday and I put in my new radiator today. It was the first time driving it in about 9 months. Although the alignment was way, way off as I suspected it would be, it was still fun to drive it around.
