Nope... I suppose it could be if you used a 9 pound sledge... A good rap with a reasonable hammer to break the damper loose when it has good tension from the puller on it shouldn't hurt a thing. Especially an old used engine with old used bearings in it. Common stuff, back on the farm... But one should just stand there and beat the hell out of it. Just put a good amount of tension on it with the puller and give it a good free swinging rap with a 2>3 lb. steel hammer. Not a dead blow hammer. _____________________________________________________________________ Ralph Ausmann - Hillsboro, OR - > http://mysite.verizon.net/res79g4m/ Classic AMX Club of Portland - http://clubs.hemmings.com/classicamx ------------previous message below--------- Date: Thu, 13 Jan 2005 20:38:39 -0500 To: mail@xxxxxxxxxxxx From: Matt Haas <mhaas@xxxxxxx> Subject: Re: mail Digest for 13 Jan 2005 in hour 0:00 Umm, isn't smacking the end of the crankshaft with a hammer a little rough on the engine bearings?
