Naps z 720 alt swap help


Recommended Posts

Hey guys I bought a 1986 Nissan 720 last night and the alt is going and here some one a vg33 alt will work. I grab one at JY today and its close but I'm having issue with the pully size. On the 720 the pully is a 2 pieces when I move it over the bolt to short? There is vg30s vg33s and a ka24de at the JY here no 720 what do I need to complete the swap.


Thanks batsun

I did one similar onto my 710. The pulley fits but you run out of bolt thread...




The nut has a shoulder on it like a washer which further reduces the threads that can reach it.



I ended up getting another nut, slicing it in half with a hacksaw, tightened it on about 4 threads, and a very small tack from my mig welder.

Does anyone know where to get a wiring diagram for the alt from a 1986 720 naps z24 to 1998 frontier ka24de

On the 720 color are white an white blue and frontier color are yellow black an green black

The saturn alt is huge! At least the one I have is.


Icoblue tried with so many different mounts to get the thing to fit on a 620.

He traded me a set of 521 bumperettes for it.

After months he gave me back the alt and a handful of obscenities.


He ended up just halfway swapping a KA DE in instead.
