Woodruff key disappeared into the abyss


Recommended Posts

While pressing on a new crank damper, I heard a 'ping' and new it was that damn woodruff key. I pulled the damper back off and sure enough it was gone. I've searched all through there, pulled the seal off, tried digging around with picks and a magnet (although a large magnet on a straight stick, not the best tool for that) to no avail. I'm dreading the thought of having to disassembly the engine again just to get that damn key back. Do you guys know of another way? If it fell into the oil pan, should I just leave it there? Is it possible it fell into one of the oil pump holes? Please Help!

It's a relief to hear you say that. Do you have any tips on making sure the next one doesn't fall out when installing the damper? Is it a bad idea to glue it in place?

A dab of wheel bearing grease should keep it in place until you slide the damper on.

Is your oil slinger intact? If you pushed the woodruff key thru into the pan, it would probably destroy the circular metal oil slinger unless you were very lucky and the notch on the oil slinger was perfectly aligned to the key.

Make sure there are no burrs on the damper that might be grabbing the woodruff key as it slides on, lightly go over the edges with a fine file.

I wonder if the oil slinger is the "metal plate" that somebody was seeing in a recent thread about the woodruff key.  He was just trying to replace the seal and ended up with quite a mess.  His key was jammed in the keyway at an angle.

I've read that some engines didn't come with the slinger and many people just leave it out after working on the engine.

Here's the thread -

The Honsowetz modify book suggest leaving it out? Don't understand that but did it anyway on my 280. The 240 has one for sure after I researched a liitle better.

Interesting....I figured if the factory installed it, so would I. All of the engines I’ve taken apart have had them. Wonder why it’s called an oil slinger?  
 

Here’s one those little suckers! Probably keeps oil off the seal would be my guess.

My Honsowetz, "how to restore" book shows the oil slinger and adds an install step. Weird how the "modify" book tells not to install it. Would be good to know why.

It's called an "oil thrower".

Thrower is an adjective. Slinger would be a verb. No? 

Lost in translation. LOL

You can still get them.  Doesn't seem to be much to them.  Wonder which way the oil is meant to be thrown.   Seems like the translation from Japanese should have been deflector, not thrower or slinger.  I'll bet it is just a shield to keep the distributor gear from piling oil up in to the front of the cavity.  Edit - actually the distributor drive gear is probably the "thrower".  It sits right there throwing oil toward the seal as it spins.

Hence, your quandary.  The "ping".  Wonder if the slinger will fit inside the seal opening.  You could still install one.

Edit - never mind, your seal is out.  Easy to do.

Those are both adjectives. Throw and sling are verbs 🙂


@Zed Head Why not. I ordered a couple.

The convex? shape sends it back towards the windshield.

Ah yes, must have been removed to prevent getting oil on the windshield 😉

What are all those nicks and gouges on the front cover?

I see a toolmark on the edge of the seal bore that has displaced meta into the bore. Take a jeweler's file and smooth that back down to restore the radius of the bore before putting a new seal in. Use a shop vac while filing to suck the metal bits away from the crankcase.

No idea. I'm not the first owner. Good call, I notice that mark there on the right side of my picture now.

I have a 2nd engine, I don't think it has a slinger either.
