just found out they installed a bigger pulley than the original .....its fixed now.....but will have to find out why and the difference in Part#......will keep you guys posted

dammm this is annoying ..... fixed everything and the timing belt is again starting to slip. Is there something i can do to make sure everything is aligned or something ?

If your serpentine belt keeps popping off, your belt tensioner has failed, your idler pulley has failed or there has to be a loose component like the power steering pump, ac compressor, or alternator. It's also possible that the ac clutch on the compressor has locked up but when that happens, the belt usually burns or breaks off due to friction.

I would remove the belt and touch each pulley that it loops around. If any of them are loose or hard to move (except the crank of course) or if the belt tensioner provides no tension, then you know what to fix.

Best of luck and sorry you're having these problems with your conversion.

A bad harmonic balancer on the crank pulley can also cause you to wear out &/or throw a serpentine belt. I have no idea of the design of the one on the Hemi, but they usually have rubber in the centre which can move out and force the belt to pull at an angle (which will wear it causing it to break or allow it to come off the pulley).

You should be able to tell just by looking at it if this is the case.

just gets more and more complicated. replaced the alternator and compared the new alternator to the old one originally on the engine that i got it with and they are slightly different. Does anyone knows if there are different alternators for the 6.4 VVT Gen 3 ?

There were some bad connectors with the 5.7 / 545 kits where the tranny position sensors weren't connecting properly. I had this problem and it was resolved with new wiring. Not sure if same connector is used with the 6.4, but is there a dealer around you that can plug you into their diagnostic computer?
