The manual tells you to check the runout but does not tell you that you'll need to have a 7/8" fine thread nut and a couple of 7/8" washers. (quick trip to the hardware store cause I could not find one from a previuos install). You need to thread the nut onto the crank so you can turn the engine around to check it.
Next a shot checking the crank runout. GP states that normal is .001" - .005" Anything more that .015" and you have problems. Mine was at .0035".
Jim...thanks for the pic of this...the instruction sheet does not show this very well, and this helps me understand that what I'm checking here is basically "wobble"....correct?
I don't have a damn dial indicator though
The instructions also say the comp nut is no longer needed, but I'm assuming you still torque that assembly down per usual?
