Help!!
While putting a new timing belt on replacement motor for my 16v, I =
notice the keyway for the shaft key on the crankshaft is chewed away as =
is the key itself on the main pulley. This is the one piece cast iron =
pulley for the timing belt and first v-belt. The problem is the main =
pulley can now be put on in a number of different positions. Even if I =
align the timing marks and tighten the bolt in the end of the crank, I =
doubt the pulley would stay there since there is nothing to hold it from =
rotating.
Needless to say, I am completely BUMMED OUT (wanted to hear it run =
yesterday) as well as PISSED OFF at the guy I bought it from since he =
told me he heard it run and it ran well. I'm not sure how well any =
motor runs when the crankshaft is off 2-3 notches!
Has anyone seen this before? Does it happen often? Or was this engine =
the victim of a bad mechanic, perhaps over zealous with a large impact =
driver on the crankshaft bolt when the key wasn't lined up right?
I've thought about he possibility of drilling through the pulley into =
the crankshaft to insert a steel dowel or two to keep the pulley from =
rotating. Does anyone know what the shearing force is on the key? If =
the force is too great, I imagine a dowel would not last under the =
pressure (less surface area than a key). Any thoughts? Is there =
another fix besides replacing the crank and pulley?
