    I'm thinking I need to start a new thread, "New 520 owner" seems a little misleading after 2 years... DR

    There is hope yet! I pulled the lifter in front of that last one, this is what it looks like: Peering through the opening, the lifter guide actually seems OK, it was really hard to get my phone to focus on the hole, this is the best I have: And trying to get an even tougher shot, this is peering down the pushrod hole to the cam lobe underneath(all the way at the bottom of the picture), it is most definitely rusted, but as I turn the crank, the other sides of the cam lobe are still shiny, maybe a cam grind would clean everything up? Looks like no matter what, that block is coming out and having some work done, now if I could only get my engine lift out from under that pile of junk in my shed! It's still a mystery to me how this rust/corrosion got there, still trying to do an F/A, hopefully not to find a crack in the block, but the machine shop should be able to tell me that. DR

    Thanks, Charlie, let me at least pull the camshaft before taking a drive out to Arizona. Seeing where the corrosion is and isn't, the lifter bore might be OK, not opposed to rebuilding a block, just don't know if it will be THIS block. I was just in Phoenix over Presidents Day weekend, too! DR

    After sitting for a year(Hockey season takes up a LOT of my time!), I finally am back on this. I did end up getting a seat from hosestop, and have replaced all the hydraulics in the braking system. Big set back this weekend though, I decided to inspect the lifters before putting the rebuilt head on, and this is what I found: Pretty bad. I was expecting some scoring, but not full on corrosion! So, I ask again, anyone have a J series engine sitting around? DR

    520 rear brake woes.

    I'm talking about the rubber hose that goes from the hard line to the junction block that splits out the rear left and right brake lines. It appears to be SAE on one side and metric on the other. The end that connects to the brake line that comes from the front of the truck is definately not the same size nut as the one I took off. I'll take some pics this weekend when I get the wheel off again.

    Thanks! At this point I should take the other side off so I can see exactly what I am really missing, someone near me thinks they have some too, along with a seat, which is super awesome! Will keep you in mind, it's good to know where the parts are as I am just getting started on this one. Thanks! As a side note, I replaced the rear brake hose with the Centric one from Rock Auto, the fitting that goes to the brass distribution block fit perfectly, but the one that goes to the hard line was rather difficult to tighten down, along with that the hex fitting on it was too small to fit in the recess and seemed to be a metric 17mm instead of the SAE fitting on the one that I took off. I went ahead and ordered the Beck Arnley one to see if it was a better match, along with some tubing and fittings in case I stripped the one that's on there. Anyone else here run into the same trouble? I am hoping that the nut is just tapered and seals as it tightens?

    That was quick! They already canceled my order, citing the same reason as the dealer.

    Called the dealer and they are no longer available, nissanpartswarehouse.com seemed to have them, never heard of them before, they took PayPal, so I placed an order anyways.

    Found this post too of someone looking for the exact same part, nissanparts.cc doesn't carry it any more, I'll try the dealer today now that I have the part number, thanks everyone for their input!

    That would be awesome, thanks! Brakes are the one thing I want to get absolutely perfect!

    Every part will be replaced, have no doubt! My problem here is that I have an incomplete system. I am using the old parts to mock up where the new parts will go while I wait for them to be delivered because I have no assurance that all the pieces are even there! Again, does anyone have a picture of a complete, correctly assembled rear brake system?

    Thanks! Maybe I read my manual wrong, but according to this parts diagram, it is actually the "Link Extension" (part #9) that I am missing. That name makes more sense to me as the lever arm is the one connected to the cable.

    I probably should have prefaced my post with saying I have never driven this truck, I towed it home about 9 months ago and it hadn't run for about 15 years. Everything is seized or locked up to some degree and I'm tackling it piece by piece. I didn't realize that there was a front-back orientation to these shoes, it's been a long while since I have worked on drum brakes. I'm hoping once I get the new shoes and hardware it will become clear which is front and which is rear. As far as how they were originally fitted, I don't think there is any way that was correct. The slot for the parking brake toggle lever is below the wheel hub, as shown in this picture(red arrow): Also, you can see how the spring bends around the adjuster, which can't be right! It also shows in the service manual that the slots for the parking brake toggle lever are above the wheel hub, once I had oriented the shoes correctly(except for the previously mentioned Front-back orientation) everything went back together like a charm.

    520 rear brake woes.

    Hi all, my first major project on my recently acquired '68 520 was to redo all the hydraulics and related brake adjustments. I tackled the master cylinder and front brakes first and that seems to have gone OK, everything went back together and I have a good understanding of how the brake adjusters are supposed to work. When I went to do the rear brakes I removed the brake drum and found them in really poor shape, there was metal on metal and lots of crud. Upon closer inspection something didn't look quite right, here is a picture of what I found. After much head scratching and looking at the two service manuals I realized that they had installed the brake shoes upside down! So I cleaned everything up as best I could, and reassembled it to look like so. Now, I know these are still not quite right, first off, I missed hooking the small spring on the brake adjuster tang, but I have ordered all new hardware and brake shoes, so I will fix that when replaced. The one thing that I really need help with is how the emergency brakes go together, I am missing the piece the manual calls "Lever, toggle (L.H.)" and am not sure I have the "Link Extension" that connects to the cable placed properly. Does anyone know where I can get the missing piece and a picture of how these brakes should look stock. The exploded diagram is great for accounting for all the pieces, but I feel like a picture would clear a lot up especially considering I have never seen what a correct installation looks like. Is there a toggle lever on both sides? I haven't done the right side yet, but am expecting the same thing there too. I have searched around and have most of what I need as far as information goes, but the one thing I am missing is a good picture of how the rear brakes go together because most forum posts no longer have the pictures included. Thanks in advance!

    Small update, just got the head back from the machine shop, it looks beautiful! I also had them rebuild my rocker shaft. Wayno, the one I got from you had taller "towers" than my original, but the shaft from mine was toast, so they took the shaft and whatever parts I needed from yours and re used as many of my original parts as they could. I'm happy the way it turned out. Any idea on why the difference in tower height? I also noticed the shaft I sourced from an MG had shorter towers like mine did, the engine appears to have been original, but now I'm wondering which ones are the original parts. Still looking for a seat!
