85 F-150 5.8 HO alternator front mounting bracket

dennisb

    My alternator is attached to the engine block withy a long bolt with a spacer sleeve and several washers and the adjuster underneath, it functions but vibrates and squeals and eventually will probably snap off .
The alternator sets back a bit and has a double pulley. is there a bracket kit available to remedy this problem?
Thank you.

maybe you could post a picture or two and we can see if there may be bracket missing

the best fix for the problem if you are not concerned with originality, would be to convert it to a serpentine belt system. this is a big job, and many are doing it but it involves many systems on the truck. I have done many and I'm doing one currently. however.. I don't throw anything away as my will attest to. I'm sure I have whatever bracket that you may be missing if we can identify it. by saying that you have a stack of washers is a clue to proper bracket/s being missing.

Mat,. Has someone removed his AIR pump without replacing the bracket?

Hard to see on my phone, but without some kind of stay between pivot and water pump the alternator is always out of line.

Going serpentine is a big job that necessitates pulling the power steering pump, changing crank pulleys, alternator, etc....

An aftermarket alternator bracket is available and is much less work.

I just converted my truck to the serpentine system and have all the old brackets up for grabs. See this thread:

If you (or someone) can identify the bracket you need from that pile, it's yours for the cost of shipping.

The alternator bracket appears to be the double 'C' shaped piece, center bottom.

I would probably take the adjuster arm with long bolt that appears at 7:00 beneath the crank pulley with it if I were you.

yes, that is the mount for both the air pump and alternator.
if that part was removed prior then I wonder what else got re-engineered too. peeling the onion my offer many revelations.

If the truck was wearing that Powermaster I would have to surmise that it was only the A.I.R. pump brackets that got docked.

Pete would know for sure. He might even have a picture of the engine before he tore the front dress off?

For now I would say that everything needed is still available.
Predicate that with "I have a 460, so can't be certain"

It was wearing the Powermaster, but that was a direct bolt-on for the stocker it replaced, so no modifications were made for it.

The engine never had a smog pump on it, so I can't say what's missing in the way of bracketry thereof.

Ah! This '81 never had an AIR pump?

Those brackets would be perfect!

I can't say that definitively. What I should have said was that in the time I have owned the engine, it never had a smog pump on it. The motor was pulled from a motorhome a couple years ago, and it didn't have a smog pump on it at that time, that's all I know.
