oldschool80sguy Posted March 2, 2012 Report Share Posted March 2, 2012 So my salvage yard trip didn't turn up much. closest i found was this one which i believe i got off an L series. lines up fine, but there is only an 1/8 of an inch between the harmonic balance and the pulley, is this a problem or no big deal?

datzenmike Posted March 2, 2012 Report Share Posted March 2, 2012 If they were to touch, you have bigger problems. Don' worry about it. Quote Link to comment
HRH Posted March 2, 2012 Report Share Posted March 2, 2012 Not enough deflection to worry about. I have the same setup on the L motor in my 510, or rather the one that's out of the 510. But that holed a piston, didn't dink a pulley. ;) Quote Link to comment
oldschool80sguy Posted March 2, 2012 Author Report Share Posted March 2, 2012 yeah, a lot of Dat peeps are telling me not to worry about it but the idea came to mind that for each turn of the balance the water pump should turn x number of times, thats what had me worried. and at dat night i saw the one i needed. it was noticeably smaller. meaning obviously that for every one turn of the balance the fan wheel was turning 1._____ something more. I know, I know, small potatoes and I'm over thinking it. i found out from nissan today that the one that bolts right up is a Z22 fan only, no clutch pulley. they want 80 bucks. uh, no thank you. I'll check the yards again and search online. its about 1/2 smaller in total diameter. thanks for the comments though. Quote Link to comment
EricJB Posted March 2, 2012 Report Share Posted March 2, 2012 Holy crap, the water pump is going to spin 5000rpms. If your upgrading for performance, you might want to slow it down. Quote Link to comment

EricJB Posted March 2, 2012 Report Share Posted March 2, 2012 wat? smaller pulley = more spin... bigger pulley = less spin. You are correct Sorry I work nights,couldnt sleep, not awake either. Quote Link to comment
oldschool80sguy Posted March 2, 2012 Author Report Share Posted March 2, 2012 yeah, that's what i am trying to avoid, less water moving. I actually found them on eBay, about 25 bucks. there's even a billet one for Z for 70 bucks that would fit. too much bling for me though. Quote Link to comment

datzenmike Posted March 4, 2012 Report Share Posted March 4, 2012 The smaller pulley are clutch fans and are limited to 2,500 RPMs no matter how high the motor revs. The bigger pulley is for direct fan coupling and will be slower. Quote Link to comment
