    Front suspension help

    The wheels are, but on the other side of the hubs is the bolt circle for the brake disk, which is 6x103 for the 2WD and 6x124 for the 4WD (4WD is bigger since the drive hub in the middle is bigger)

    Front suspension help

    Turns out the hubs weren't my problem. I bought the wrong disks. Somehow I ordered 4WD disks which have a bolt circle of 6x124mm instead of 103mm. looking at the hubs that I pulled off the junkyard I4 D21, they look identical to the ones that came off my '79. Is this possible? Do I still need V6 hubs? I thought the V6 and I4 hubs were the same,that just the calipers and disks were different. I measured the brake disk bolt circle on the hub and it matches the spec (103mm) on the BrakePerformance website. I went ahead and ordered a new pair of disks. So $100+$127+a monday afternoon down the drain. Anyone need some black Brakeperformance slotted and drilled 4WD disks?
  3. i was thinking of you when I came across it, you are welcome to them my friend.
  4. Went out to South End Auto Wrecking in Renton to pull some hubs from a 620 and found this: it's a 4WD with its' rear springs intact as far as I could see. this was on 4/10/17

    I should. Both are D21 and the spacing looks right. As soon as I have the proper hubs I will be mocking the whole thing up to the wheel. "Belltech 2005 dropped spindle Datsun 720 2 wheel drive pick-ups Nissan hardbody 2WD pick-ups"

    Front suspension help

    Ah, got it. I thought that I had bought the spindles for a D21 but looking through the Belltech paperwork I think it actually says 720. I'll check if I remember tonight. Some pics of the setup as it stands for clarification: So, I need to find my way to a Pick&Pull around here and get a pair of hubs and brake backer plates.

    Front suspension help

    I've read through a lot of the front suspension threads, but it seems I may have gotten off track somewhere. I've got a shortbed '79 which I'm tearing down at the moment. I thought I had a solid plan for the rebuild which was this: 620 hubs - Original 620 bearings - new D21 Slotted rotors - Aftermarket D21 V6 calipers - junk yard pull 720 Belltech 2" drop spindles - Aftermarket 620 ball joints - new 620 control arms - Original I've discovered that the 620 hubs wont fit the D21 rotors So it looks like I'll be scouring the yards for another D21 with good hubs. But will these fit the 720 spindles? If not I suppose I need to look for D21 drop spindles (which should be easy to find) but am I at that point going to have a ball joint fitment issue?
  9. I've got a lot of rotten wiring in my '79 620 and currently I have no spark. So I've got some wiring to dig through and probably replace, but I've got the following questions: What does the ignition module do? The coil boosts the voltage from the battery, the distributer times the spark, what more is needed? I don't understand the purpose of a fusible link. Can I replace this with a fuse? If so, what rating is the link supposed to fail at?

    Metal bed

    What about adapting another bed to it? I have seen examples of stepside beds dropped onto 620s before. At the bottom of this thread is such a 620: http://community.ratsun.net/topic/2243-real-museum-620s/page-2 This would be a lot simpler than trying to fabricate one from scratch, and potentially simpler than importing one (certianly cheaper) Just off the top of my partially informed head, to ship one you have to pay for the item, crating of the item, shipping of the item, customs fees, duty on the item, lading of the item, and storage of the item. Instead, get yourself a bed off of whatever compact truck is common over there and drop it in place. I'm sure that some cutting and drilling will be needed, but these beds are relatively standard sizes and it's not as if the Datsun bed really fits the body lines of the cab anyway. Personally I think the stepsides look really good. EDIT: Upon looking into it more, the stepside bed was offered by an aftermarket company in California for some time in the 70s, so some did "come" with it. But I stand by my statement that adapting another bed to the frame is likely easier than making one from scratch or importing one.

    Bendix fuel pump

    Well, guess what. The secondary idle jet is missing. Just a hole in the side of the carb. This is a new truck to me and I've never driven it more than 100 feet at a time and am not familiar at all with Weber carbs. Sounds like a trip to Carbs unlimited is in order. I've placed an order for a new filter screen for the pump. Apparently they're now manufactured by Facet and used a lot on light aircraft, so I found the part on pilotshop.com.

    Bendix fuel pump

    Given the flow that I saw out of it last night I'm confident that the pump is not my issue.

    Bendix fuel pump

    I pulled the pump again yesterday, cleaned it up and it turns out it is not a Bendix. The cap on the top is stamped "Bendix License XXXXX" so it's a licensed Bendix copy. Anyway, there is no filter in the bottom of it. Either it's missing or this copy pump never came with one. There are two clear plastic filters downstream of the pump, one 6 inches down from the pump and another in the engine bay, but nothing to keep debris out of the pump itself. The one 6 inches down from the pump has all the evidence of being stock since there is a hanger for it attached to the pump mount, the one in the engine bay is just an inline spliced into the soft line. I replaced all of the soft line under the bed and I replaced the filter back there. I pulled the soft line from the carb and put the line in a paint cup and turned the key, the flow looks really good. Putting everything back together I got in the truck and tried to start it up. After priming it started up fairly confidently with the choke on, and ran for long enough for the revs to start picking up, at which point I slowly started to open the choke, but the revs would drop too low and it tried to die. It currently doesn't seem to want to idle, so there's still some work to do. Once I get some good data on what she wants to do with a few more tests I will probably be posting some more questions. Digger48: I know that I can get a generic pump, I have one from Autozone. I don't have a lot of faith in it though.

    Bendix fuel pump

    It's a '79 shortbed single cab. I don't know if it has a regulator. I never thought to look for one. Would this be under the cab? Weber DGV I did pull the hose off, and it did dribble gas (it didn't shoot it) but I don't really know what the flow should look like so I can't say if it was flowing like it should or not. I haven't looked into the carb while trying to start it after it dies so I can't say what the accel pump does in this state. When I have started it again I usually let the pump run for a moment before turning the key to start thinking this might help fill up the bowl again (assuming this is the problem)

    Bendix fuel pump

    Do you have to remove any of the clips or springs to access this filter? I popped the bottom off yesterday and didn't see anything that looked like a filter. I wasn't really looking for one though, I was trying to assess the rebuildability of it​. Stock cutaway picture: http://minkara.carview.co.jp/en/image.aspx?src=http%3a%2f%2fcdn.snsimg.carview.co.jp%2fminkara%2fphoto%2f000%2f002%2f742%2f805%2f2742805%2fp7.jpg%3fct%3df2042ef71acf That lower area where the "heavy duty fuel filter" should be looked empty from what I recall. I should be able to take a picture of the fuel pump flow to the carb this evening. That might give the experts here an idea if my problem is what I think it is.

    Bendix fuel pump

    My 620 will start up and run for about 5 minutes at a time at which point it seems to run out of gas. I take this to mean the fuel pump isn't keeping up. I've pulled the vent line off the tank thinking it might be plugged and building vacuum, but no change. My first thought is to put on a new pump or rebuild this one, but these things are expensive, and the rebuild kits don't seem to look correct. It's an electric pump mounted next to the tank which I gather is fairly rare for these trucks. It's pretty dirty and corroded, but I can just make out the brand Bendix stamped into the top cap. Is there a common alternative to this thing? Or should I sink the $90-$250 that the ebayers are looking for? It would be cool to have a shiny new vintage one for sure. But if there is a more reliable alternative I would prefer to go with that.

    Mysterious fuel lines

    Cool, thanks. Then what's the one that dumps into the filler neck just below the cap? Filling vent? I imagine the vent you're talking about might not be fast enough to work as the fill vent, it's pretty small. My Ranchero used to puke out all its gas if you tried to fill it too fast.

    Mysterious fuel lines

    I've got the bed off my '79 (with electric fuel pump) and the filler neck is trash. It's rusted through in a couple of pinhole spots. I've placed an order for a new one off Ebay, but I can't figure out what one of the lines on the old one is for. The new one does not have it, nor the plate that it's mounted to. There's the feed line that goes straight to the frame rail mounted pump There's another line that comes from under the cab and goes to the side of the tank (I assume this is the return line) There's a third line that goes to just under the gas cap (vent line) And there's a fourth line that comes from under the cab, loops up near the top of the fill tube and comes back down, through a black plastic filter looking thing and back to the top of the tank. What's that fourth line? something to do with emissions? I suspect it may be related to the line on the drivers side of the engine bay that has a wooden dowel rod shoved in the end of it.
  19. Thanks for the advice friends! I adjusted the float this afternoon and she seems to want to run for as long as I like now. It was pretty far off, I had to bend it down at least 15 mm (the bowl would have been filling about 15-20 mm too high) now it should shut off flow much sooner. With this change it will run more consistently. So on to the next issue if you don't mind. Now it will start up and run with the choke pulled. With it fully out (fully choked) it will run, but is a little poppy and shaky. With the choke about half way in it runs the smoothest. With it all the way in it dies. This is all on a fairly warmed up engine. I figure this must mean it's running too lean. ...so, back the idle mixture screw out? Also I tried to fiddle with the distributer and find the sweet spot. It didn't seem to make a lot of difference except that all the way clockwise would kill it. I also put the timing light to it, but the block is so crudded up I couldn't see any marks on the pulley or the plate. I'll get some more cleaner in there when I get a chance to clean that up.

    -32 damn! What'd you get?

    Wheel calculator

    I had a whole 5 minutes of searching, and confirmed that no one had posted willtheyfit.com and it's still the only one that will show an overlapped comparison which I find much more helpful than any of the other calculators I've seen, including the rimsntires one. Single box shipping for 4 15x8s along with a steering hub cost me $470 through Jauce (total breakdown of the costs involved is below). Single box means they only put them in one box vs doubling the crates with packing material in between, they are still shipping as two parcels, two wheels to a box (one with a steering hub inside). Wheels total: $(650.27) Auction price $(117.71) 13,000 yen JAUCE.com auction fee $(18.43) 2,000 yen bank fee $(2.76) 300 yen local delivery $(18.43) 2,000 yen packing fee $(22.11) 2,400 yen international shipping $(470.83) 51,100 yen

    Wheel calculator

    http://www.willtheyfit.com/ I was looking for a calculator and came across this cool site that will SHOW you exactly how a new set of wheels and tires (tyres) will compare to another. I've got a set of wheels coming from Japan right now and was trying to figure out what size tires I might want for them, willtheyfit is really nice because I would like to keep the same rolling diameter (or at least know how far off I am) and that can be a pain to figure out.

    Metric U Bolts

    In that case Daniel, what would you say about 17-4 U bolts? I would lean toward 17-4 because it machines really nice and easy. Otherwise I'll just be using some cold rolled steel rod. But stainless is a lot cleaner to cut.
