socorob Posted March 24, 2014 Share Posted March 24, 2014 I've been making slow progress on mine. When I first put it in a few months ago, the part that relocates an idler pulley didn't fit. He calls it the spigot. Went to napa to see if they had a bearing with the same size OD as the one in the LS pulley with a smaller ID. The one he sent was too small. No go. I called John and he said machinist had a heart attack and is in hospital or something and went and checked and batch is made wrong. Of course I got the 1st from that batch. He sent me another bearing with a little piece of metal bent into a curve. It's supposed to take up the slack between the spigot and the bearing but its still not enough and I don't want to use it because its not even a bushing.It has about 1/32 of slop when it's installed. It's been a few months and he said he still hasn't been able to get the proper one. Anyone else has this problem? I don't want to do to a machinist to have this made, or borrow my friends lathe because I paid for the part and got sent the wrong one. I'm getting close to start time and can't even start the car with that piece. Quote Link to comment Share on other sites More sharing options...
NgoZ Posted March 25, 2014 Share Posted March 25, 2014 I ordered kit 2-3 months ago and it's been sitting in my shed waiting till I have time to actually put it in. Will be a few till I am able to actually drop the motor, if I have the right piece can give it to you till you get the right one to give back.

RebekahsZ Posted March 25, 2014 Share Posted March 25, 2014 Are you talking about something for the airconditioning? I don't have airconditioning, but there was no idler pulley in my kit-didn't need one. Must be something new? Please clarify then maybe I can help.

socorob Posted March 25, 2014 Author Share Posted March 25, 2014 Thanks for the offer, but I will end up making one if I absolutely have to. I'm just trying to find out if I'm the only one with this issue. Hows your car coming? Quote Link to comment Share on other sites More sharing options...
Kevin.pk Posted March 25, 2014 Share Posted March 25, 2014 i'm guessing this is specific to the A/C install. Is it for the Idler in this pic? (not my car. borrowed pic from old post by savage42) Quote Link to comment Share on other sites More sharing options...
socorob Posted March 25, 2014 Author Share Posted March 25, 2014 Yes its for that one. The bolt for the alternator goes through it. Quote Link to comment Share on other sites More sharing options...

By the way, the picture 280Zcar posted is not how the JCI A/C kit is supposed to be mounted. See picture for proper mounting (According to John).

socorob Posted March 25, 2014 Author Share Posted March 25, 2014 Yeah I think mine is more above as in the 2nd picture. I will double check. The 1st picture probably doesn't have enough belt to pulley contact. Quote Link to comment Share on other sites More sharing options...
280zjake Posted March 26, 2014 Share Posted March 26, 2014 There is another option that mounts a Sanden SD7 mini compressor on the passenger side down low and back that runs off the back balancer grooves. Keeps the top of the engine a lot cleaner and tucks n very nice.. Quote Link to comment Share on other sites More sharing options...
Phantom Posted March 27, 2014 Share Posted March 27, 2014 (edited) My AC compressor and alternator are mounted as shown in Alainburon's photo. Don't know if anything has changed since mine was done - it was the first - but the one I have is solid and trouble free.

CableSrv Posted September 25, 2015 Share Posted September 25, 2015 I know I'm bringing this up from the grave but I have questions... I recently just got my jci ac compressor and mount and there is something that I'm not understanding. The compressor hits my water temp sender! Where can I move it to? I cannot use the passenger side water temp hole as that is already being used by my water temp gauge from prosport. I see phantom has his drilled and tapped into his head? This bothers me because I don't like the idea of drilling my head especially since it's on the engine! Plus if I ever decide to get aftermarket heads.. I can't expect to drill/tap those and keep a warranty. So where can I locate this to? Also the JCI kit proved a very thick and large aluminum washer that is threaded with a bolt and plastic washer in it? The bolt is the exact same thread size as my water temp sender... so I guess this was used to block off that hole? So what is the threaded washer for? Unfortunately no instructions were included in my package.and last... what belt should I get? Right now I have the ac delete belt on which will be way to small for this. Would a stock belt work?

socorob Posted September 25, 2015 Author Share Posted September 25, 2015 If I remember right you took out a freeze plug and put that washer in and use that for the temp sensor. Somebody correct me if I'm wrong, it's been awhile and I try to not remember all the work I put into this car. Quote Link to comment Share on other sites More sharing options...
CableSrv Posted September 25, 2015 Share Posted September 25, 2015 that was for using the stock datsun water temp gauge. I use a aftermarket prosport gauge and have used the water temp hole on the passenger side. The ecu on the other hand STILL needs it's own water temp sensor and am currently using the stock location. However the jci mount for the ac compressor causes the compressor to hit that sensor location. From the pix that phantom has, it looks like the moved the sender to the front of the head and drilled/tapped it there... however can that be done with the head on the engine? won't metal filings fall into the fluid? I don't want to spend money on a new head bolts and gasket just to remove my head so I can install a damn water temp sensor. On top of that... if I ever buy new heads aka AFR's, I know drilling and tapping those will void any warranty I have probably. So where can I relocate my ecu's water temp sensor? And what is that giant threaded washer for? Quote Link to comment Share on other sites More sharing options...
JoeK Posted September 25, 2015 Share Posted September 25, 2015 Why can't your gauge and the ECU share the same sensor? Quote Link to comment Share on other sites More sharing options...
CableSrv Posted September 25, 2015 Share Posted September 25, 2015 (edited) cause my gauge uses a certain ohm sender vs what the ecu uses. At least that's from what I know. The gauge came with it's own sender so I assume it has a certain resistance it needs to read vs what the stock sensor produces.

CableSrv Posted September 25, 2015 Share Posted September 25, 2015 Ok, just called John and he clarified the issue. The head has a freeze plug at the front.. (I thought that was a cast area and was meant to be drilled through) After pulling the freeze plug, his huge thick washer with inner threads for the temp sender gets put in it's place. It acts as the new freeze plug.So Socorob, you were absolutely completely correct! I guess I assumed you were talking about the block freeze plug that is bolted in. I didn't think that area on the head was a freeze plug... apparently I'm retarded and it all makes sense now. So when I get home, I'll need to drain the coolant and pop that freeze plug out and get something to hammer in the washer in it's place. So last thing I need to know is the belt... anyone got a part number for the belt I need? or does adding back the ac and moving the idler pulley to end of the alternator bracket let me use the stock belt?

Zzeal Posted September 25, 2015 Share Posted September 25, 2015 So where can I relocate my ecu's water temp sensor? Mount it into an adapter like this and splice it into your upper radiator hose. PM me if you'd like to buy it. Quote Link to comment Share on other sites More sharing options...
Jay Gadsby Posted September 25, 2015 Share Posted September 25, 2015 Run a piece of string on your accessories, measure the length, count the ribs and go to napa. Has always worked for me when I need a belt on my marine motors. Way cheaper than marine dealers Quote Link to comment Share on other sites More sharing options...
CableSrv Posted September 25, 2015 Share Posted September 25, 2015 So got the washer pressed back in the freeze plug area and got the compressor mounted... went to use the bushing for the alternator and apparently I need to press out the original bushing or else this bushing won't go in... ugh... really wish there was a warning that if you ever plan to go AC on the JCI kit it's best to do it BEFORE you put the engine in the car as it's a complete pain in the ass later to remove all the crap.
