Re: Mercury crank
I have about 10 Flathead Ford/Merc cranks here at the moment. All are 8BA style, later pieces!
They both measure about 7.000" across the front c/weights, if there is any difference it is immeasurable with a conventional ruler.
The plugs are another story, the Merc is .625" (5/8") like mentioned above. These actually lend themselves very well with this size to drill & tap fpr a 3/8" NPT pipe plug, requires no add'l drilling. We do these all the time!
Thanks, Gary in N.Y.
P.S. Here's a shot of a Merc on one of our balancers now getting balanced. On the left I wrote the dimension (7.000") in "chalk" to show the span of the c'weight, on the right that single line shows the pressed-in oil plug, it measures 5/8". I can supply a shot of the front c'weight on the 239" Ford also if necessary?
