Questions: My 46 CJ2 engine has a double crank shaft pulley, will the 647629 fan belt fit this engine? Thank you
Question By: jimbob on Jan 10 2019 2:07 PM
That would be unoriginal if your double groove. But if you are double groove then use part number: 118866

Questions: I purchased a wide belt from NAPA and my crank pulley and water pump pulley are wide but I have an alternator and it has a narrow pulley. Will your belt work on my jeep if I can get it tight enough?

I would address the improper pulley on your vehicle. It may work if tensioned properly though and not slip, but its not ideal.

Don't do it. Get the right size pulley or you will tear up your bearings in the water pump and alt.
