Bent Rods
Does anyone know if Kohnke Rebabbitting is still in operation? I’m suspecting that I have a few bent rods in a newly done engine and would like to have them all checked. Herm had done excellent work for me in the past and I do know that his son was continuing the business after his passing, but haven’t had any luck reaching him. Also, who else is reputable for rod straightening nowadays?

Re: Bent Rods
It's not rocket science to make your own mandrel to check them, they can even be realigned in a good 6" bench vice.

Re: Bent Rods
Dave, since you are sharp enough to be concerned about bent rods, you know how to avoid bending them during piston installation & removal.
I will say, I check every rebabbited rod I get before installing. Around 1/2 from suppliers are out of square/bent.
I have found bent rods in fresh rebuild motors that I had to go thru to correct builders errors.
Trust but verify.

Re: Bent Rods
I agree with John, even though you pay "good money" for re-Babbitted con. rods, one should verify that they are straight !
Stevens & KR Wilson both made superior tools for checking rods - I also have a flywheel attachment for setting magnet heights for my Stevens.

Re: Bent Rods
This is my Ausrtalian made set up for rod aligning.
Instead of multiple round mandrels to take multiple sized rods, it comes with just 3 machined square mandrels. These can take rods as small as T up to large diesel truck rods. My local machine shop never had a use for their small one, so it was given to me.
10 years later my cousin found the matching precision vice used to straighten rods.

Re: Bent Rods
The fixtures show up @ swap meets occasionally but, the seals are rarely with them & a hard find.
Simple, functional substitutes can be made from about a 4" notched square plate.
