This little key is 5/8" X 3/16". I don't recall putting it in the new engine. Should I be worried?

Dave ......
Isnt that the key for the fan Mount?

Yeah, isn't that the key that locks the fan on the crank?

If that came out I would think you could move the fan pretty easily.

Don't know but I hope not. It might be a little tough to do with the enging in.

From Pet:

9, 901 102 147 00, WOODRUFF KEY, 1

How do You capture the image out of PET?
Tryin to send post it for you Dave

Dave I would be very very worried, I don't think I could sleep at night. But then that is just me.

It can be put back in with the engine installed, I have done it a lot. Just hope it didnt do any damage to the crankshaft. Dont run it without that in there.

STOP!!!\

Yep!! it's the fan hub key!

If you don't have one it will take out your crank!

Be safe and make sure.

Dave, I'm holdin one just as you described. What I can't understand is how it came out as you prolly installed the fan well ahead of the tin. It's like working blind but it can be installed in the car.

I took mine out today for shits and giggles on any and all curvy roads given the dry weather. You'll be glad you made the heat exchangers.

Happy holidays to all, Tim.

Damn Mark, I got wood lookin at all thoes heads on your avitar.

Tim

Um...I guess I'll ask the obvious (and betray my ignorance!!) But, how does the fan hub key come flying out the front of the engine? Is it sloppy engine building? Does this happen to high mileage engines? How might I ensure that my current and future engines don't have this problem? Is this some sort of engineering/design flaw with the T4?

Happy Holidays Fellas!

It cannot "fly" out...period...no way, no how !!!!

possibly just unlucky, when he installed the hub, it might have come loose, or it could still be installed correctly on the crank and this is an extra part from another project??? We won't know until he takes it apart, he needs to measure it 1st, if the dimensions are too far off, then i wouldn't worry about it, however if the dimensions match what belongs in the crank, then I'd be cussing

No

Don't worry about right now with your current engine and when you rebuild your engine remember to install it....

QUOTE

No, it is not, it might be a human error and that is all, the Type IV engine is a very robust engine

It might also be the WOODRUFF KEY that's used on the inner half of the alt. pulley.

With the indents on the edges....looks like a beat up/severed dime....

Actually I would do it from underneath. Just take the front apron sheet metal off. You should be able to get at the fan hub while seeing what you are doing. Plus you get another chance to gawk at that beautifull motor from the under side one more time. Good luck Any chance it came from the other crank when it was pulled apart? WAY LONG TIME AGO????

Well I took the front apron off and then the fan and hub and I found a Woodruff key right where it was supposed to be in the crank. Guess I'll try the alternator next.

Dave

Unless the pulley came off of the alternator, there is no way for the key to get out. As you can see the key fits into a hole in the shaft. It cannot slide out. Then there is the washer and nut on the end it could not get past.

My guess is that it's an extra.

I've been finding extra parts in my engine compartment for years.

-Lawrence

never say never

I'll pull the alternator out this afternoon. I can't see how the key could be from there but, I've worked too hard on this not to spend an extra 45 minutes or so to find out. If it didn't come from there I guess I'll write it off to gremlins (same category as JP's magic smoke).

I raced a 1350 Merc for over a year with a nut and 2 washers left over after putting it back together. I never had a problem.

Dave

Effin' gremblins. That's one of their tricks. Sneak into the shop and strategically place a gizmo (bearing half, piston circlip, O ring or 2,....woodruff key) in a spot where you'll be sure to notice it .....and that's only when you're done doin' some motor work. A hungry 20lb barn cat will often keep them away.....but cat piss is hard on alloy wheels
I heared Wolverines work even better, but there are serious side effects.....

See if you can get some of them attack Chichuhas
Or Maybe Rob Watson can loan you one of them Killer Dashounds.

My gremblins hide stuff from me.......

I put it down, it's gone

I search all over and....... nuttin.

I move every thing and still can't locate it.....

Move the stuff back and it's still gone...

Ask others to look around for me (younger eyes) and... still nuttin

Give up in disgust.

Come back later

....and it's laying in the exact spot I thought put it down in: wacko:

This has been goin on all my life....

Think I need help...

Ken

Well it wasn't any gremlins. It was the mechanics error (ME). TC914 you da man. It was the Woodruff key off the alternator shaft. DaveP don't worry it was my fault.

Here's what I found when I hauled the alternator out. No nut on the shaft.

I found the nut under the car. And I found my large cresent wrench in front of the alternator on the front apron this morning when I pulled off the fan to check the fan hub. I thought that was kind of strange but it was early and I was tired so I didn't make a connection. So, how did this come to pass. Unless gremlins can lift large cresent wrenches, I suspect I left it on the alternator pulley nut. I was using it to turn the engine to find TDC and forgot about it. I think when I started the car it spun the nut off. DOH!

See no Woodruff key

Pretty damn stupid mechanic. All better now, but, man I'm tired. Oh ya, it took a lot longer than the 45 minutes I thought it would. If I had to do this for a living I'd starve

This particular gremlin is named Dave

One and the same.

Dave

Good job figuring out what the problem was! I learned a coupla things as well...That's what it's all about...

The 20lb barn cat would definately keep the Gremlin's out of my garage...

I'm allergic to cats.

Sure glad you found this before serious damage.

you sure it wasnt this gremlin?

I could easily keep on of those Gremlins out of my garage "without" the help of a cat.

That being said... I'll bet those are starting to go for some money now

Blame it on the KIDZ!!! Couldn't have been the BEER!!!

funny thing is....i got no kids.....maybe the gremlin got them too

Dave,

Did you find the big washer that goes under the nut on the alternator shaft? You will need that also.

Dave

Well I have to admit I've been there done that too.
Well almost but just as funny.

Put a ratchet on the harmonic balancer of the Ranger. Don't recall what I was doing but left it on. Come time to start the engine and I heard this Really loud whizzing sound. Quickly shut it off and spent several beers trying to figure out what the hell that noise was. Not until I crawled up under the thing and nearly knocked myself silly did I figure it out... 1/2" Craftsman Ratchet going backwards at 1000 RPMS.
