Feb 09, 2011 · you can install the alternator and with the belt installed tighten the nut up. however you either need to use a wrench or drop the passanger side of the engine so you have clear access to the nut. also the engine spins in the way that the nut tightens, so theroetically it can't loosen up, iirc.

It is polished aluminum and a 2V belt. The V is a nice wide V. Notice how the belt fits right down in the Vs. Gets plenty of traction. The polished surface should not give you any problem. If your belt fits down in the V and still is slipping, take some 60 grit sandpaper and rough up the sides of the V.

Dec 02, 2018 · Throw a wrench on the pulley nut on your alternator, whatever direction you can turn it without the belt slipping is opposite the direction your engine spins, so when you get the belt moving watch which way the crank pulley turns. If it turns clockwise, your engine operates counter lockwise. Jul 27, 2015 · Diodes can fail open or fail shorted, either way you lose.

Which way to spin alternator bolt? Rule of thumb. If the engine rotates clockwise, which it does, then any pulley driven by the inside of the belt rotates.

Pulleys on AC and Alternator tensioners: identical?.

Nov 22, 2003 · I have replaced the alternator recently and just yesterday replaced the waterpump. For some reason the alternator pulley does not line up with the fan pulley. It actually sits a little sideways, which causes the belt to rub on the pulleys. I have tried to use washers to adjust the alternator either way, but can't get it just right.

Take the inner splash guard out from behind the tire. Now get a long punch and tap it free with a hammer. A steel dowel, allthread, or the like can be subbed for the punch. yeah, i removed the splash guards, but the bolt thing has to come out from the other way. Like, I have to knock it out that way.

Here is more info on how a sprag clutch in an alternator pulley works, it is in section 3.2. I am not sure this is the same design as is found in the Colorado alternator, but should be similar. If a sprag clutch fails it can result in the alternator not spinning at full speed in the correct "positive" direction as it should and could result in. That makes the belt walk across the pulley as it goes around it, and that is what sets up the squeal. As little as 1/16" is more than enough to be heard. It is caused either by the pulley where the squeaking occurs, or the pulley right before it. The culprit will almost always be one of the smooth pulleys. Looking at the front of the pulley, they spin clockwise. David TLCA 14788 71 FJ-40 TBI 327 w/TH-350... They charge turning either direction. The fan is designed to take the air from inside the alt and move it out the front (fan side).... Don't know that I have ever seen an alternator fan that turns the other way.

If it is the alternator not moving, you need to loosen the bolts holding it to the bracket and then slide it so the belt will go on. Did you simply cut the old belt off without loosening the alternator first?.

The only place I could find a new replacement alternator pulley was at FCP Euro, the price was only $34.99, but there website mistakenly stated that it would also work on a Valeo alternator, when it would only work on the Bosch alternator's. FCP Euro has since corrected this after I spoke with the parts manager. 3,579 Posts. #2 · Nov 10, 2011. Yes it's possible to put it on wrong. I used the picture from the Bentley manual to see how to put it on; it was pretty clear. The belt should feel VERY tight. If its not, it could still be spinning the alternator, but not enough to charge properly. Y. Mar 20, 2022 · The alternator pulley should only be turned in the anti-clockwise or counterclockwise direction.

Signs of a bad alternator pulley When the car’s alternator pulley fails, the presenting signs are usually pretty clear.

Can you turn an Alternator backwards? - Don Terrill’s Speed-Talk.

If the engine is running, but the belt is not turning, the drive belt tension is inadequate, the belt routing is incorrect and/or other rotating elements (pulleys, etc.) in the serpentine belt circuit are seized. Jul 26, 2021 · Depressor pulls up the fan belt and see if your belt is too loose or too tight. If your belt is worn out, the pulley might not be able to give enough pressure on the belt, and that can cause the squeak. Step 2: turn on your engine, while it’s squealing, spray it with WD40 or water and see if the noise will stop.

Mar 15, 2022 · The Good. When an alternator is good, alternating current is being generated by the rotor and stator, the rectifier is converting it to direct current and the regulator is controlling the output. If a problem develops with one of these, the result is either no voltage, too much voltage or an AC-voltage output. Any of those are bad. Either way, the voltage is now 12.81-12.86 at idle (and my ol' lady has gone to work so I won't have anyone to hit the gas until later). I think the belt tension was the solution! (As for the alternator, it's a rebuilt unit from NAPA that I installed earlier this year. It shows that it was tested to 34 at 2000 RPMs and 78 at 6000 RPMs.). Using an impact gun will occasionally remove the nut, allowing the alternator pulley to be removed. The best method of removing the nut and alternator pulley is to loosen the nut while the alternator is still on the vehicle and prior to loosening the belt. This method uses the belt's tension to hold the pulley while the nut is being loosened.

I went to German Auto Parts, got a new belt, kept the tensioner, had them replace the pulley (i bought in the alternator) and went home to reinstall the alternator taking a chunk of my thumb off in the process. If you can get that alternator out and in, just replace the pulley. gforce1108 Top Post Dawg Joined Aug 2, 2006 Location Newburgh, NY TDI. If you are willing to try, just remove the pulley from any mechanical tensioner unit and compare it to the new one that you got for your hydraulic unit... I was going to suggest something like that too...You need to change the pulley on your mech. AC tensioner. When removing a belt, slacken the main bolt by 1/4 of a turn MAX. Then slacken off the tensioner. Then slacken the main bolt. Replace belt and re-tension as above. If you slacken the main bolt too much before releasing the tension, you can easily ruin the rubber bush. No easy way of telling by inspection visually.
