That tool makes life so much easier .. got all the finger prints wiped off?

If you put sealer on the crank and key, oil will not leak from under the bolt and fling off on your new March pulleys.

How does that happen? oil leaking through the crank bolt? The only place your going to get oil is through the timing cover front seal and there is no sealant that could prevent that, you would need to replace the seal.

i made the same mistake one before.. I didn't use an air gun, but I tore the first few threads out of the crank. Igot lucky and ran a tap down the snout and cleaned up those first few threads.

I made my own installer by basicly just using a really long bolt of the right threads, then I just used a washer and nut.

Oil will wick through the woodruff keyway channel, believe it or not- that's why the OM uses that Right Stuff- like sealer material on the damper ID.

Well that is a first, have not had or heard of that. Not that I have had or heard of all the problems one encounters time to time, but that is an interesting one I must admit..

Yep, happened to me on my original installation of the crank hub for my blown SBC. Couldn't for the life of me figure out where the little drip of oil on the back of the crank pulley was coming from for the first hundred miles. Even went so far as to replace the lip seal in the timing cover. I happened to mention it to a motorhead buddy of mine, and the first thing he said was, "You did put some sealer in the key ways of the crank snout and hub, didn't you?" Ummm, no. "Well, there you go!" Pulled the hub, sealed the key ways, put her back together... no leak!

Just had the same problem, a dab of silicon on the keyway solved it.
Dippo me even bought a new timing cover, one piece, I had blamed the leak on my Edelbrock two piece.

What a trip talk about a hair puller, wonder how long that has been known?

Ok thinking about it I suppose the oil could possibly come in from the rear of the balancer, that make sense ........ been lucky so far never had it happen ... all good here.
