Skulptr Posted December 24, 2011 Report Share Posted December 24, 2011 i picked up an 85 720 KC for pretty much free, had no engine or transmission. i put the z24 and trans from my standard into it. this KC has powersteering, the PO left the pump hooked up. i bolted it to the engine where it should go, now my problem is, if i put the belt on to drive it, it looks like the belt is going to hit the fan clutch/water pump. does anyone have a picture of a z24 with the power steering pump mounted with a belt, so i can figure out what i'm doing wrong... i really want my power steering, turning 33s with arm strength is getting old.

ggzilla Posted December 24, 2011 Report Share Posted December 24, 2011 When it has Power Steering, all the pulleys are different. Not just the PS pump. Quote Link to comment
datsunaholic Posted December 24, 2011 Report Share Posted December 24, 2011 This won't help, but it's all I got: There's an idler on the driver's side which makes the belt clear everything. If you don't have the idler, it won't work. Quote Link to comment
ggzilla Posted December 24, 2011 Report Share Posted December 24, 2011 after looking at the service manual, it seems the pulleys are not different. PS pump on the right side of the engine, idler pulley, and crankshaft pulley. The PS belt doesn't go round any of the other pulleys (water pump or alternator, etc.) Quote Link to comment
Skulptr Posted December 24, 2011 Author Report Share Posted December 24, 2011 crap so there is an idler pulley.... now i just have to get a picture of it so i can go hunting in the JY tomorrow... Quote Link to comment
ggzilla Posted December 24, 2011 Report Share Posted December 24, 2011 It looks like most Datsun idler pulleys. Just a wheel on a bracket with a threaded bolt for adjustment. You'll see it at the J/Y. But they might differ Z22 to Z24 to SD25. Both Z idlers are probably the same, but you never know Quote Link to comment
Skulptr Posted December 24, 2011 Author Report Share Posted December 24, 2011 sure doesnt seem like the belt napa sold me today would be long enough to clear an idler pulley as well, but i wont be able to find out til i find one... Quote Link to comment
izzo Posted December 24, 2011 Report Share Posted December 24, 2011 hold on ill go snap a pic real quick. Quote Link to comment
Hardwyre Posted December 24, 2011 Report Share Posted December 24, 2011 You don't always need to use the factory suggested belts. Once you find an idler pulley that works, take a piece of rope and bring the rope end to end around all of the pulleys the regular belt would go through, then measure the length. Use that to find a belt long enough. Just make sure the width and depth of the "custom" belt is the same as the suggested factory size, other wise it'll sit too far or too deep in the pulley grooves. This is what I did for my Z when I swapped out the alternator for a 140 amp Cadillac DeVille one. :) Quote Link to comment

But they might differ Z22 to Z24 to SD25. Both Z idlers are probably the same, but you never know The SD22/25 power steering pump and idlers are under the injection pump basicly on the bottom of the engine, and you access all of it from the bottom except for the fluid reservior itself. If you ever see a stock diesel power steering system for sale, or in a wrecking yard, PLEASE tell me, as I will buy it. There are a lot of 720s out there with power steering, finding what you need should not be that difficult. Quote Link to comment
Hardwyre Posted December 24, 2011 Report Share Posted December 24, 2011 I wish I knew how rare the diesel L motors were. I found a diesel maxima months back (should have pulled the damn brake brackets for the Toyota brake upgrade) and grabbed the intake for an intake upgrade, but then decided to go with the VH45 swap down the road instead.

elmerfudpucker Posted December 24, 2011 Report Share Posted December 24, 2011 Sorry to jump in but I have the whole power steering setup like that in the shed sans idler. Couple racks of coke in the glass bottles from costco and you can take it. Quote Link to comment
Sealik Posted December 24, 2011 Report Share Posted December 24, 2011 Since we're talking about PS...here's the Z24 assembly on the L motor. Nip and a tuck...with a plate to stabilize the idler pulley....good to go. Quote Link to comment

Skulptr Posted December 27, 2011 Author Report Share Posted December 27, 2011 can anyone get a PN for the pulley?? i went JY hunting today, managed to find a bracket, or what i believe to be the bracket, has an adjuster, bolts to the head opposite the power steering pump, but i have no pulley. napa doesnt show any idler pulleys for and datsun pickups. and they dont believe me that it does indeed exist.

ggzilla Posted December 27, 2011 Report Share Posted December 27, 2011 Nissan is the place to buy non tune-up parts, like idler pulleys. Quote Link to comment
Hardwyre Posted December 27, 2011 Report Share Posted December 27, 2011 Summit lists this pulley as being used on the Z24 and the Z24i, but it's listed year starts in 1986. What year truck did your engine come out of? http://www.summitracing.com/parts/DAC-89036/Application/?query=Year%7c1986%7cEngine+Designation%7cZ24 Quote Link to comment
Skulptr Posted December 27, 2011 Author Report Share Posted December 27, 2011 My engine came from an 86, but the power steering is in the 85 already. The 86 didn't have it. Quote Link to comment
nismo dr Posted December 27, 2011 Report Share Posted December 27, 2011 Idler pulley - 11945-03G0A - coming out of master depot $43 Bracket - 11946-W0500 - coming out of Sacramento $29.20 prices are with the Ratsun 20% discount already applied http://community.ratsun.net/topic/38095-20-off-for-ratsun-members-gladstone-nissan/ shipping would be extra Quote Link to comment
Skulptr Posted January 9, 2012 Author Report Share Posted January 9, 2012 well i finally got around to tracing around an idler pulley. the 11945-03g0a can be googled and gotten for 40 bucks flat. or you can go to napa or orielleys and get the pulley p/n 38036. i found it by mistake. orielly, napa, summit, rockauto, and almost everywhere else have 38037 or similar listed as the 1986 p/s idler pulley. i bought one for 25 to find out the shaft size was too big. i took it back, after a little while we discovered another 81mm pulley, next to the one they have in the system. sure enough, it fit perfectly. and was only off by one number. not to mention 38036 was 5 bucks cheaper. picture, left is the listed, right is the correct. after a few 7/16" washers as spacers, and a 2nd belt (napa got that one wrong too) i finally have power steering again. makes turning these 33s a lot easier.

Hardwyre Posted January 9, 2012 Report Share Posted January 9, 2012 Looks good. Seems like it's poking out of the pulley just a little more than it should, but that probably won't cause any issues. Quote Link to comment
Skulptr Posted January 9, 2012 Author Report Share Posted January 9, 2012 Yeah it is a little more belt than I wanted but its snug in the groove with no gaps so I can't complain. It'll work its way down given time Quote Link to comment
