crankshaft specs

49ford · 07-21-2018, 12:04 PM

I have an 89 DS flathead that I had the engine overhauled by a 3rd party, to be nameless for now. After putting it back in the cart and getting it going, there is a noise under the seat. I pulled the drive belt off and it still makes the noise. The clutch has a small wobble. So I removed it and put a dial indicator on the shaft. It has .013 side play. That's too much isn't it? Measured on outer end of shaft with dial indicator.

I looked up the definition, and the spec I'm looking for is the "runout".
I'm also wondering if the engine bearing is the source of the noise I'm hearing.
