everything was going smooth until I looked at the hole for the pilot bearing to go into. The jeep is a 92 and the engine that was in the jeep is a 92 4.0 with a manual tranny. the engine I thought i could swap in is 96 4.0 that came out of a auto tranny eqipped cherokee,and i was planning on using the manual tranny that was with the 92 engine. the pilot bearing fit in just fine,so i was thinking this should be smooth sailing from here out. well,then I got to looking at the end of the crankshafts for both engines. the 92 has a 1/4 deep bigger hole and then the pilot bearing hole while the 96 has a 7/8 inch deep bigger hole and then the pilot bearing hole. there is no way that is going work is there? I would think the input shaft of the tranny wouldn't reach the pilot bearing. there is a big difference in the mileage of these 2 engines,and to swap crankshafts,i would have to have the 92 shaft machined and then get new bearings. that is more time and money than i am willing to spend right now. Is the difference in the crakshafts a big problem or am i just over reacting,and this isn't a problem at all?
On edit: the bigger/deeper hole I am talking about is the "hub" the flywheel bolts up to. the one for 92 is 1/4 deep and the one for the 96 engine is 7/8 deep. the 92 flywheel fits on the 96 just fine.
