Re: Need 740 B230F engine parts
The car suffered a crankshaft pulley failure months ago, Got it going
again with a new crankshaft pullley. When I took that off and checked
the crankshaft sprocket, I found that there was a little fragment of
what was a key in the crankshaft keyway. Well, there is a square
projection on the front of the sproket which engages the corresponding
keyway /slot on the crank pully. On the back side of the crankshaft
sprocket there is a corresponding dimple and some little thing, maybe
a "bump" projection was there, that has broken off. But I don't see
any slot running axially on the ID of the sprocket which the
crankshaft key would engage! Doesn't make sense. I don't see how the
crankshaft key was positively set/anchored to the camshaft pulley and
sprocket, there would just be the tension of the pully bolt. But I
figure getting a new sprocket and key should solve the mystery and fix
it. The Haynes illustration isn't clear or detailed enough on this.
