[SEL] FM Mdl Z Style C 3HP

[Jim Jirik]

I took a tape to the flywheels and measured between them in different positions.  At most places it measured 17-1/4", but there was a place that it was 1/16th more.  Is that enough to assume a bent shaft?  And to let you know, it is only the one flywheel that wobbles.  The other seems to run true.

Yes ! You get to rap it smartly with a pein !

If the mains are worn enough
the con rod could push the crank to and fro , up and down .
the flywheels would appear to wobble , (actually jump around and
ammer  )but not just ONE of them
Both wheels will have to flop around before it could be considerd to have
anything to do with bearings .
 You want to prove it to yourself  ? take a tape measure and measure
between the wheels,  roll the motor around
180  degrees and measure again  . the numbers will be different if the crank
is bent .
One of the things I carry a tape at swaps for is  to watch for bent cranks .
They throw em off the truck onto the ground
at thats it .  Enjoy your new toy .
