I have only put 8k on my Vortech and I think I have a bearing problem. The supercharger was making a loud whining funky sound I couldn't go through drive through). My mechanic looked at and thought definately a bearing and un hooked s/c. Anyone else have this issue and what was problem?

 

Do the whine get louder as the rpms climb? Probably the bearings in the jackshaft. A few of us have already replaced those bearings. Let me see if I can find my old video of the problem.

 

I was told others have had this issue, how was Vortech about fixing issue? How long did it take and was it under warentee?

 

If the idler pulley that is on the blower belt isnt put on right . The bearing in it may go bad and start to squeel also

 

They wanted me to send the whole unit in so they could diagnose it themselves. But after talking to a couple people who had the same problem, I knew it was the jackshaft. There are two bearings that go in there. I didn't want to wait weeks for a problem that could be fixed in a day. So I ordered the two bearings @ $10 each and had them replaced.

Here a video of the noise: http://s114.photobucket.com/albums/n...t=MOV03078.flv

Here is a semi-DIY:

yeah I wouldn't mess with the vortech warrenty unless the blower itself seems to be bad. The time it'd take you to take out the blower, ship it to them, wait, wait more, get it back just isn't worth the small money out of pocket expense of buying the parts and getting it fixed on your own

I had a jackshaft bearing go bad. The specific part ended up being like $100, but wasn't too bad to replace my mechanic said. It was really worn down - still have it. Looks like someone took it and put a grinder to it and really dug into the metal

 

I've also replaced the jackshaft bearings. PITA, but better than dealing with Vortech.

To diagnose better, we really need to know where exactly the sound is coming from. Pics of your setup wouldn't hurt either.

 

need new bearings bro, sorry to say

NEXT TIME

1- install the idler pully corectly
2- do not tighten the $hit out of it

I got 15k miles on the vortech and 0 problems. no slippage unless its a super hot day like 100 degrees and still on the same belt as day one.

 

The sound seems to be comming from the right pulley. I have disconected belt from S/C and all is quiet. Could I have messed things up by putting 3:12 pulley kit on. A slight vibration under hood at 70mph after kit was installed. Do you need to mess with idler pulley when installing 3:12?

 

You may want to loosen up the serp belt all the way [ at least till you can turn the jackshaft pulleys freely ] While you have the blower belt off . Tighten down the tentioner pulley for the blower belt and see if it turns freely . Also see if both pulleys on the jackshaft turn freely . You maybe able to eliminate what bearing is bad [ jackshaft or tentioner ]

 

I have the small belt off so I can still drive car and all is quiet. s/c is not running. I am somewhat clueless when it comes to this sht. All pullies are spinning except the one thgat comes directly out of the s/c.

 

Chances are that it is the tentioner pulley bearing then . BUT...it could still be the jackshaft bearings . With little load on the jackshaft it may not be making any noise .

 

What would you do? I hate to have s/c sent out if mechanic can fix pullies.

 

It might be your blower. When I took the cog belt off the SC, the noise was still there. Meaning that the SC was not causing it. I could have sworn the sound was coming from one of my idler pullies as well, but it turned out to be the jackshaft bearings.

 

I doubt it is the blower . More than likely a bearing in the tentioner pulley or the jackshaft . Take it to a shop that did the install or one you trust

 

If it's a bearing in the tentioner pulley or the jackshaft do I need to send out s/c to Vtech

 

It turns out that it is the jack shaft but Vortech told me it was $650 for the part. What to do?

 

getting fixed would be what I'd do

 

How did you come to that conclusion? Is the actual shaft bent? Was it the same noise as I posted above?

 

Same noise as above.
