I have a 85 6.2 that I pulled the turbo 400 off. Removed the flexplate and installed a NAPA flexplate to mate to the 700R4. I was under the truck checking for leaks, I hadn't installed the inspection cover yet.

The flexplate has a noticable wobble? No noise or rubbing, just not running true.

This is my second 6.2 that I am runnning in my 85 Toyota Landcruiser FJ60. The first was a military take out. The harmonic ballancer had a noticable wobble and that motor broke the crank. I purchased this motor in a running 85 p/u. The flexplate is off the motor that broke the crank behinde the #2 connecting rod. I left the harmonic ballancer that was on this engine as it runs very smooth, no noticable wobble.

The flexplate that was for the turbo 400 is much stouter looking and feel then the NAPA replacement.

Is a bit of wobble OK?

Thanks, Jim
