Perhaps this should be in the Corvair engine section, but there is much more activityin the Piet section, and plenty of Corvair gurus. Simple question... does this look like and 8409 crankshaft to you guys? This numberis stamped between the 1st and 2nd connecting rod journals. The "84" portionas perfectly clear, but the other two digits could be an two round characters...difficult to make out. Could it be anything else? I mean, were thereother series of numbers they stamped that may be similar, or is it a prettysafe bet that "8 4 X X" is 8409.--------Mark - working on wingsRead this topic online here:http://forums.matronics.com/viewtopic.p ... ttachments: http://forums.matronics.com//files/8409 ... __________

That's an 8409 crank, Mark. To me, the '09' is faint, but it's there. Either way, the only other codes that would be stamped are 5607, and I think 7293. So you have the right one.

Sure looks like it to me. The other way to tell, if your crank wont turnenough to see the number is by looking for the case clearance cut out wherethe connecting rod bolts go past the side of the case right by the cylinderbore. Stick the tip of your finger in there and feel for the swath of thecase that has been machined out to clearance the travel of the connectingrodbolt. If it does not have it has the old short throw crank. Not the endof the world but the case made for the 8409 is the desirable one.To see what you are looking for on the case go to Pat Panzera' page at:http://www.experimental-aviation.com/Co ... .htmlfirst pix is an older case for the short throw crankthe third pix is what you are looking for.As you notice Pat shows us the way to make an old case fit an 8409 crank.So if some one gives you an old case I would not turn it down either. Awhile back I was the fortunate recipient of just such a gift via ourcomrade at arms Alan Lyscars. Some day I will try Pat Panzeras conversiontrick just for yuks.Michael----- Original Message -----
