Crankshaft pulley fitment

[JayJay]

So: new to me 1930 pickup, resto early 80's by the previous owner, less than 1000 miles since then. Maybe an opportunity, maybe a "uh-oh". Anyhow, there's a vibration in the engine I've been trying to track down before pulling it and doing a full rebuild. In the process I noticed the crankshaft pulley was wobbling, so I purchase a new one-piece to replace it. There was a big chunk broken out of one spoke on the old one, so I was thinking "yippee, I've found it!"


Well, got it back together and nope, the vibration is still there. But funny thing - the new crankshaft pulley is rubbing on the front motor mount. Worked a shallow groove in the pulley and took a corner off the motor mount.


I think it would be fairly easy to relieve the motor mount a few tens of thousands to clear, but has anyone heard of this before? I was thinking maybe somewhere along the line a slinger washer was left out, but the pulley fits to the crankshaft just fine (slightly protruding past the end).


Perplexed. Thanks.
