NAA 134 crankshaft hitting oil pump housing

I had a similar problem with a rod bolt contacting the oil pump housing when I rebuilt my jubilee. I was using the existing crank and rod. I installed all new rod bolts when reassembled. I had to remove that conflicting rod bolt and shorten it slightly to gain the needed clearance. Sure glad I noticed the problem before installing the oil pan.

Good luck. Dan R
