Water pump wobble?

[forfamily]

Ok, it has been a long time...

We are trying to smooth this 289 out as much as possible and the water pump bearings seem to have some play in them. If you grab and move the fan blades you can feel a little bit of play in the bearings. Is this acceptable? Seems to me there shouldn't be any play.

If the bearings are starting to go and the fan where to wobble won't you be able to feel it in the car?

Uh... get a new water pump. Unless the fan bolts are loose, I can't beilieve you even asked. No, on second thought, I can't believe you asked.<a href="http://www.smileycentral.com/?partner=ZSzeb008_ZNxdm117AAUS" target="_blank"><img src="http://smileys.smileycentral.com/cat/4/4_12_13.gif" alt="Light Bulb" border="0"></a>

Water pump wobble

Well, sorry to ask the obvious,

Like I said, it has been awhile, that combined with the previous owner saying the pump was replaced last year...

Wait, do you have a flex fan on the car or is it a stock fan with a fan clutch? The fan clutch might be bad and not the water pump. If the water pump bearings were bad, I think it'd be peeing all over the ground.

First Tighten all bolt conected to the water pump. then if it still wobbles change it.

You'll have some wobble before the "peeing" starts. It's a warning sign that you might want to pay attention to

Yes, definitely tighten the alternator bracket bolts, and the power steering ones too.

If it has a clutch fan, I'm still betting that's it.

Look at the shaft as you move the fan, is it moving?

Water pump wobble

Just a flex fan, no clutch.

No leaking, yet...

Yes you can see some play in the shaft and pulley if you pull on the fan blades.

I will probably go ahead and get a new pump. However here is my follow on question (and I guess what started it all). Is the clearance between the pulley and the top bolt supposed to be this tight? It is maybe a 1/16th of an inch and any wobble in the pulley and starts skimming the top of the bolt (and sounds like crap).



Thanks for the help, sorry if these questions are a little basic, the car is a couple months new to us and I would rather ask a couple dumb questions then learn the hard way!

Oh, forgot to mention, everything is tight and checked the alignment of the pulleys and everything looks good.

Hmmm, never seen an aluminum plate like that on a 289. . . .

It seems that the aluminium bracket is the cause of your lack of clearance and a longer bolt was used to attach it.

Do you have an aftermarket AC unit or am I missing something?

Yes, supposedly it is an orginal dealer air installation?
