4" Merc crank & rods
I'm trying to figure out what a 4" stroke crank 2" rod journel
crank and matching set of rods are worth . Rods are standard and mains are -.020. Both are in good shape for reconditioning . |

Re: 4" Merc crank & rods
Are you sure it hasn't been stroked to 4 1/8 with those 2" rod journals? Which rods do you have?

Re: 4" Merc crank & rods
As stated if it does have a 4 inch stroke with a 2 inch rod journal it is most likely stroked.
As I recall all stock cranks with 2 inch rod journals were 3-3/4" stroke (including Mercury) Last edited by 34PKUP; 04-22-2019 at 07:32 AM. |

Re: 4" Merc crank & rods

Re: 4" Merc crank & rods

Re: 4" Merc crank & rods
Pictures may or may not help but why not re-measure the stroke just to confirm your initial findings?

Re: 4" Merc crank & rods
Hi all, The rods have B38 marked on 1 side and 91 over H4 on the other
side of beam. The #2313 is on a counterweight. It does not appear to be offset ground . I would measure the stroke but it's not easy without a block. I guess I'll put it on the lathe . The mains are only .010 under. Maybe it is a 3 3/4 crank ? Thanks for reply's''''''''''''''''''' RJ |
