Hi All,
While installing the impeller I noticed a missing blade & found two more that are cracked. See pic.
The book says it's a "balanced" assy... more like "was"!!! (IMG:style_emoticons/default/sad.gif)
What should I do now??? Thanks, Gary

That's common. People like to stick screwdrivers in there when changing the fan belt or getting the engine to turn for a tune up etc.

Call here and talk to the Cowboy. I'm "guessing" Rich'll have 1 or 2 laying around (IMG:style_emoticons/default/laugh.gif)

Oh... and yes, it's best to get a new one and keep the assembly balanced.

You want the cheap way? Go to the exact opposite side of the fan and remove corresponding blades. Very carefully polish the remaining casting flash and run it as is. You should not ever have a problem with it.

Remove the opposite blade, not a bad idea, except that it has two other blades that are cracked as well.
I'm gonna go ahead & replace it now while the engines still out of the car.
Thanks, Gary

Porsche says never run one with more than 3 missing blades. That is all I have to say.

I remember seeing a post awhile back about how all but a few blades were removed for better air flow or maybe I had a few too many Buds.

Hmmmmm. Let me get this straight: (IMG:style_emoticons/default/idea.gif)

We're looking at an engine that's currently out of the car, has a missing fan blade and has a few more cracked blades. Last I checked, I couldn't sell a spare fan for $10.00 and the consensus is "to remove more blades at this time..." (IMG:style_emoticons/default/smilie_pokal.gif)

Sounds good to me. (IMG:style_emoticons/default/laugh.gif)

I just checked the bird parts website. They have a "new" fan for $271. - & rebuilds are NLA.
I'll call HPH next...
Thanks, Gary

I had one FS in the classified here for quite some time. Finally sold it for around $10.00.

Crack the blades exactly opposite of the already cracked ones (IMG:style_emoticons/default/smile.gif)

I thought they worked better if you alternate, cutting out groups of four?

This was a big discussion around here once.

Added a handful of horsepower.

Go here quick and snap this puppy up.
Fan on Ebay

Ask the seller if it has all the blades BEFORE you bid.

Hi All,
You'se guys crack me up!!! (IMG:style_emoticons/default/boldblue.gif)
So much info - thanks soooo much - now I've got "options" (IMG:style_emoticons/default/beerchug.gif) Awesome!
I had NO idea that removing blades was even an option. But it did make me think...
Many years ago I was a tech/mech for a large aircraft engine accessory manufacturer.
One of my many tasks was to overhaul (ACM's) Air Cycle Machines. The overhaul was a piece 'o cake. The dynamic balancing was a stone BITCH!!! (IMG:style_emoticons/default/headbang.gif) But once you learned to balance - your next raise was a sure thing.
BTW - Removing blades was NOT an option... (IMG:style_emoticons/default/alfred.gif) (IMG:style_emoticons/default/cool_shades.gif)
This is my daily driver (once I surgically remove her from the jack stands).
I'm in O.C. Ca. & it gets HOT here. So I'm thinkin' I need ALL of the blades for those times when I'm stuck in traffic on a 90+ day. Am I wrong??? Tell me - I can take it.
Thanks again, Gary

This is the type of help I have always appreciated from ALL of you/us teener people. We have fun, take our shots, have a few laughs, and exchange a wealth of info that helps keep/get our amazing 'lil cars running & on the road. and DOOOHHH - we DON'T discuss politics.
