Batsun Posted August 11, 2013 Report Share Posted August 11, 2013 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 Quote Link to comment

datzenmike Posted August 11, 2013 Report Share Posted August 11, 2013 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. Quote Link to comment
flatcat19 Posted August 11, 2013 Report Share Posted August 11, 2013 Or go get the KA alt. Quote Link to comment
datzenmike Posted August 11, 2013 Report Share Posted August 11, 2013 Or go get the KA alt. ... from a D21 Hardbody. These are the ones with the V belt. The S13/14s are serpentine belt Quote Link to comment
RadioRedline Posted August 11, 2013 Report Share Posted August 11, 2013 There's no d21s at the JY. Closest I guess is a Ka24de frontier... Radio Quote Link to comment

flatcat19 Posted August 12, 2013 Report Share Posted August 12, 2013 Any quest vans? Older Altima's? Quote Link to comment
datzenmike Posted August 12, 2013 Report Share Posted August 12, 2013 If you have this style plug on the Frontier alt Connect the wire on the right side above to the bottom one in the picture below . Quote Link to comment
Batsun Posted August 12, 2013 Author Report Share Posted August 12, 2013 Those are the plugs Quote Link to comment
RadioRedline Posted August 12, 2013 Report Share Posted August 12, 2013 He got it to run! Now just sorting out gauges and fan as we speak. So KA24DE Alternators = 620s, 720s?! Radio Quote Link to comment
datzenmike Posted August 12, 2013 Report Share Posted August 12, 2013 It will fit a 720 because the steering idler arm is outside the frame rail. The 620 doesn't have much room for anything larger in there. You can try... Quote Link to comment
RadioRedline Posted August 12, 2013 Report Share Posted August 12, 2013 So what ALTs do the 620 people upgrade to?? Radio Quote Link to comment

RadioRedline Posted August 12, 2013 Report Share Posted August 12, 2013 That's it...shit son Radio Quote Link to comment
datzenmike Posted August 12, 2013 Report Share Posted August 12, 2013 Look up 'one wire alt. swaps' or 'Saturn alt. swap' there are tons of options and how to's on this. Some are for the 620 I think. The Saturn alt. may be small enough. Quote Link to comment
flatcat19 Posted August 13, 2013 Report Share Posted August 13, 2013 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. Quote Link to comment
datzenmike Posted August 13, 2013 Report Share Posted August 13, 2013 But the 720 does have the room for it. Quote Link to comment
flatcat19 Posted August 13, 2013 Report Share Posted August 13, 2013 But the 720 does have the room for it. No idler. Quote Link to comment
datzenmike Posted August 13, 2013 Report Share Posted August 13, 2013 It's there but not in the way Quote Link to comment
heretic Posted August 13, 2013 Report Share Posted August 13, 2013 I put a 97' Saturn SL1 95amp alt in my 78' 620, works great. So what ALTs do the 620 people upgrade to?? Radio Quote Link to comment
