Getting Yoohoo Belt On
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.

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.

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

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.

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.

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...

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.

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.
