If the a_c belt won't stay on check to see if the mounting bracket isn't broke and everything runs in alighnment. What we have found is probably your viabration dampner on the front of the crankshaft is getting bad and causes the belt to fly off. As far as the cummins conversion this cost is about 13,500.00 and another 1,800.00 for the mounting kit. You would have to really like your N6 alot or plan on keeping it for a long time to make this pay! Take care of your engine, it should last you a long time if you replace the rod brgs. at 1400hr. intervals. The N6 combine is a good work horse and can push almost any other combine on the market.
