    Speedometer cable

    So turns out the tach wasn’t the last thing wrong with the truck. When I pulled the speedo cable out from the instrument cluster I noticed oil leaking around the area, I have actually noticed some oil in that area since I acquired the truck. Also some oil on top of the transfer case under the truck. Anyway I looked at this post Wondering if anyone has since tracked down a reliable source or part no. for a new cable, or for the seals individually. as always, any other advice would be appreciated. thanks james

    Looking for speedometer cable with intact seals for 1985 Nissan 720 z24, manual transmission. i believe part no.b5050-t7200

    The infamous tachometer

    I see all of these going to the wire harness.
  4. This is (almost) the last thing not working on my truck at the moment. The 2.2k resistor checks out. Ive pulled the instrument cluster to examine. The yellow wire is getting voltage. But that must not be all it needs? any thoughts? after pulling the tach from the cluster, it appears to be in such excellent shape and I find it difficult to scrap such a fine piece of engineering and manufacturing.
  5. Better late than never. tested for vacuum leaks and everything was good. i installed redline part no. 99007.115 it is a throttle adapter kit. I want to do a write up on this, and how I installed it, but I cannot say enough positive things about it. This took my truck from being something incredibly difficult to drive, to having an accelerator pedal that feathers like a dream. No roller bearings needed, at least not yet. it was relatively easy to install, and it repositioned the throttle pull toward the driver side of the truck (factory has it pulling toward the passenger side). Only slight modification necessary. truck running pretty wel, none of the solenoid cut offs I bought seem to thread into my carburetor, the choke assembly is way to close, and the thread size for the primary choke is the same as the secondary, so maybe there is no part for this particular carburetor. Any leads on this would be helpful. still dieseling but suspecting that jets need to be adjusted slightly, possibly downsizing the idle stream, and even the main jet to make a more lean condition. will post on throttle adapter soon!
  6. I like the idea of putting bearings in, but I’d like to address the simplest things first, and fine tune from this point. For e.g. the throttle return spring has been rigged to the supplement hydraulic clutch booster line... the throttle cable bracket had never been lined up very well and so that hasn’t helped things either. This is another project. I made a new bracket but have since ordered an adapter through redline. As for the adapter plate: when I reinstalled, I cleaned up the questionable work. When I removed the carburetor, one of the studs hadn’t been seated into the intake manifold, it had been, amazingly, tapped into one of the frozen manifold studs. Anyway, I removed all of this and started over. When I reinstalled the intake manifold to adapter plate gasket, I put a thin coat of grease on the intake manifold side. (This was recommended by redline). How do you all check for leaks? Vacuum or otherwise.
  7. There aren’t many vacuum lines to be leaking, and I capped off anything that did have a line previously.
  8. Spray starter fluid around the carb w truck running and listen to engine?

    Fusible link

    As far as I could tell from my research, the wires were all tied together in the main harness and that was linked directly to the positive, so that’s what I did with the copper ring terminal.

    Fusible link

    Yes! It was just a bunch of random spliced copper wire before, now it is the fusible link.
  11. That is really helpful, thank you. It’s interesting because according to the literature I have referenced, Weber recommends increasing primary idle jet when the mixture has to be turned out >+2 turns, which is where I am at. all of my jets are as listed for the 32/36 dgav except the idle, and as of now the primary idle is undersized. Will report back on this once I play with it, idle cut off solenoid comes on Friday!

    Fusible link

    I tried to match the original wiring, and where that was not possible, I checked the gauge size of the load side and scaled the fusible link accordingly. I feel a lot better about this. https://ibb.co/tPjF75D https://ibb.co/5h1JrLJ Next is the tachometer. Only gauge that isn’t working. I’ve tested the resistor which comes out OK. That is as far as I’ve got. Do you have to remove the instrument panel to remove the tach? Ive noticed that the bulk of the problems with this seem to be a bad tach.

    Fusible link

    So I’ve been working on the 720, rebuilt the carburetor and removed most of the vacuum lines. Now I’m looking for this holy grail of a part http://datnissparts.com/x-fusible-link-assy-for-datsun-nissan-720-pickup-24022-10w00-can-replace-24022-06w11/ It is the “main” fusible link that pops on to the positive post and goes to the alternator, ignition switch etc. The existing wiring is pretty bootleg, and so I figured if anyone had a lead on a part like this, or a creative idea to make something work. Thanks
  14. Hi all. Everything made it back onto the truck with no extra pieces. I pulled almost all of the vacuum lines, as several were routed incorrectly anyway. I have 2 observations and would appreciate any insight and opinions. The truck fired up immediately and idled with hesitation for a moment before cutting out. I started to adjust mixture for lean-best, and, as was the case before, I had to back the screw out about 2 1/2 turns. It does seem to idle just fine, maybe at a slightly higher RPM than before. I almost have no adjustment on the idle speed screw, which is also a little bit different than previously. The other observation is that it diesels pretty badly when I cut off the engine. Typically it would do this maybe one in twenty times (one in five times on its worst days). I do have an idle cut off solenoid coming in the mail and was going to play with that, but I can’t help wonder if these two items are related. I also found an old post And this actually lists some specs for the 32/36, which are pretty close to what I have in there, but not exactly. Both of my idle jets are 50, and the specs listed above call for 55 on primary/50 secondary. How much difference would that make? Anyway thanks for any responses and thoughts.
  15. Was anyone able to use the above link for the google document images?
