SIX fan problems, metal on metal Options

[Trekkor]

So, I put the new alternator in and install the fan back in it's housing. Fan spins free with no issues.

Then I put it in the shroud and tighten up the strap around the alt stand.

When I run the motor it makes a horrid scraping sound and metal shavings are a flying. (IMG:style_emoticons/default/headbang.gif)

Why? Help me.

[FONT=Arial]Okay....

from reading your other message about the voltage reading...it made me wonder if the alternator internals are chewing up?

were you able to spin the fan (without the belt) freely and no noise?

if there's noise, try rock the fan up and down, side to side to see if there's any cocky movement....if so, that's a big NO NO...your alt bearings are more likely shot...

If there's no sign of rocking movement, then start turn the fan a rotation at a time to catch the scuffing or scrapping sound, then stop right there....back up a bit, go forward again till you trace the sound source, then let me know where you find it.....we go from there....it's hard for me to help you out without seeing the actual fan assembly....

by the way, is the engine an original 2.0L 9146? the timing chain cover looks very 'vintage'! Especially the left one when looking at the engine, the cover has a provision for mechanical fuel pump back then when running the zenith carbs....Not the MFI as everyone knows but way before that, there used to be a mech. pump there.....I hope I'm right on that as it's been a long while I've seen that type of engine...
