Any other problems you ran into?
Very good job!
Good question... The Harmonic Balancer came with the 5.9 motor... use it only, the pulleys from the 5.2 were a direct swap. Also, the Flex Plate must be used from the 5.9 since the 5.9s are externally balanced.
I scored the motor from a 2000 Durango with 40K on it. Its almost all the same as any 5.2/5.9 ZJ. Exceptions are Obvious (EGR on some years) Oil pump has a longer pick up tube than the Jeeps and oil pan has a bulge at the front and thin in the center to clear the IFS Dodge front ends. SO swaping oil pump/pan is a must. The accesory brackets are the Exact same mounting, as well as timing cover etc. I used the 5.9 Distributor only cuz it was covered in oil like my 5.2 version, other wise the same exact part.
As for harness' the ZJ sensors did not match the sensors on the Durango. ie Crank Position sensor (I think) had 2 wires, where dodge has 3. But thats how many of the sensors were, including the Oil Pressure Sending unit, and Temp sending unit.
Its a pretty easy swap for a 5.2 to 5.9 but otherwise I imagine it being a BEAR going from anything else.
Used an inspection scope to check the cylinder walls and it looked great. Turned it over without any resistance. Everything looked real good on this motor. Asking $400, got it for $370. Its now sitting in my garage waiting to be installed. I'll put in at least half a day tomorrow.
