Put the stock Alt back on!

Is the 200 Alt seized or is it time for a new belt?

Well it HAS been time for a new belt......But if I need to get a smaller belt than I need to know. The pulley on the 200 amp is smaller than my stocker 140.

So If I have to replace the belt, I don't care.

The nut on the alternator is usually difficult to get off using a regular socket with ratchet. Your best off using an impact gun to remove the bolt which will not damage the alternator. I would also change your belt, and use a gatorback back belt. The gatorback belts are specifically designed not to slip under tension.

If you swap pulleys it will not be a 200 amp alt anymore. I'd get a smaller belt from NAPA (Gates).

That'* what I ended up doing. I was hoping somebody maybe had P/N'* because the store closed in 20 min, and I didn't wanna hear that I needed a tensioner lol.

Your old belt must of been really stretched out to slip on the alt., being where the alt. is and how the belts are ran. I like the Gates belts because they will hardly (if at all) stretch let alone the fact that they grip grooved pulley like a mother. What size pulley does that alt. have on it anyways? Ryan ended up putting a smaller pulley on his alt. to help with dimming, to keep his volts up at a stop, and to charge his huge *** batt.

If your 200 amp pulley is smaller you have less tension on the idler pulley with an already streched belt. Look at the tesioner marking lines and see if they are within operating range. You could have the parts store look up the length of your belt then go down in length by 1/2 in or so. This should do the trick.
