    Speedometer drive seal?

    New o-rings from hardware store fit fine, but of a pain to wrestle inner one in and out, but it’s in there. I ended up just using a rubber washer between the drive and cable housing. The fit was pretty loose around the inner cable, but I figured out that seal just keeps oil from getting into the cable housing. The outer portion is the one that keeps gear oil from getting to outside, of which the flat rubber washer should do the job. I also put some ultra black rtv around the end of cable housing before tightening it down, just for good measure. I drove it around a little to make sure Speedo works, and then let it sit all day. No signs of gear oil leaking down cable anymore. If I get some gear oil inside my speedo cable housing, hey, free lubrication? Not sure how much/if it can hurt, and I’ll keep my eye out for a replacement for that top hat grommet. I almost had something that would work at the hardware store, some rubber cord protectors I could cut up. Inner diameter wasn’t quite small enough and outer flange not quite big enough, though.

    I picked up a whole bunch of o-rings, rubber washers, grommets, and ultra black RTV; and we'll see what works after I get done mowing the grass tonight. With any luck, I may have to drive truck a couple hours to pick up a swing set this weekend.

    wait, are you DaveR or did he grab pics from you? Hah. Seems like if rubber is fairly pliable, should slip on from bottom. The old one slipped right off of bottom. Center ring not damaged, only outer ring. Don’t think Teflon tape would help on threads much, it’s not leakin from threads. It’s coming right down the middle along the cable housing. It eventually drips onto my exhaust, which is the real problem. Stinks like hell, and probably a fire hazard. I might consider packing some rtv around the cable housing as well before tightening it down.

    So, googling other Datsun speedo cables to see if there's similar, I found this Z car thread, in which the cable end and grommet looks exactly the same as mine: https://www.classiczcars.com/forums/topic/55640-speedometer-cable-grommet-trans/ No good source for that grommet alone, but one guy said you can just use a flat rubber washer. I'll probably do that for near future, and see if it leaks anymore. If it still leaks, order a new Zcar cable and steal the grommet out of it. I've found some for $30 to $50 incl. shipping.

    Speedometer drive seal?

    Finally got around to taking it out. When I first put a wrench on it, realized it wasn’t in very tight, so I tightened it up and saw if it would hold for a week or two. It did not. When I took cable off, realized a weird seal at end of cable was real busted up. Doubt I can find a generic for that. I further took the speedo drive gear out, with a 1 1/8” socket, it all slid right out. A quart or 2 of gear oil did drain out, woo. The internal and external o rings didn’t look terrible. No signs outer was leaking, all oil was coming out center. Internal ring seems ok, but some has to be getting past it. A refresh on that will help it from getting to that outer weird seal until I can find another one of those. I’ll get a pic of the assembly shortly.

    Speedometer drive seal?

    Hey, at least that gets me to some webpages now! I think I tried those numbers before when I looked in the 320 parts catalog, but got zero results, not sure what I did wrong. This transmission certainly looks like mine: http://www.carpartsmanual.com/datsun/bluebird-1964-1965/power-train/transmission-case/4-speed I actually think the J13 in my truck may have came from a 410 and not a 520, forget how I reached that conclusion, maybe the number on the block. So, my tranny could be original or from the donor. So, they're just simple rubber o-rings? By those figures, the speedo drive gear itself will slide right out without any further disassembly of transmission? So I can slide speedo gear out, then take it to hardware store and find some suitable o-rings, then pop it back in? That's not too bad at all, then.

    Hey, we talked about this very thing before! http://community.ratsun.net/topic/34539-1966-datsun-520-transmission/

    Sorry, its parked outside at work and a bit tough to get a good pic. I assumed all 320s had the dipstick, or is mine just a weirdo? I love it, its right by the gas pedal. https://imgur.com/a/fknSw1L The shifter sits up in a weird little housing of its own, which leaks a lot of oil too. At least its up high, and I can check my dipstick regularly.

    Speedometer drive seal?

    Anybody have any luck finding something that works for a seal in the speedometer drive? Is it just felt or a rubber o-ring? I've found several part numbers in the old parts catalogs for 320s and 520s, but can't find anything via google when I search for a source. I've got a lot of gear oil coming out of mine and onto the exhaust. It's in a '65, 4-speed floor shift, with the dipstick. I'm not sure if this is an original 320 transmission or something from a 520 (truck has a J13 swapped by PO, not sure if they swapped transmission too).

    Hand crank for a 320?

    I forgot about this. Here's the crank that came in my trunk, it was fit snugly in the mounts behind the seat as well. Yeah there's an odd bend in it so it won't lay flat, cuz top quality, I guess. The perpendicular pin is about 1 1/8" .

    Hand crank for a 320?

    I guess I have no idea if mine is original or not, but it came with it and works. The Model T in the ebay ad I posted actually looks like its built a lot better than mine. I can get some pics at some point this weekend, but I'm at work right now and the Datsun doesn't come out in winter. My truck came with a J13 engine that lacked the receiver on the crankbolt, and I put on a crankbolt from a Datsun Roadster. I tried a crankbolt from an MG, and it could receive the 320 handle just fine, but threads weren't right on the crankshaft side.

    Hand crank for a 320?

    Just searching ebay, there are a number of hand crank starter handles that may work from old tractors and Ford cars. It's not exactly a precisely machined piece, and the end can be tweaked if necessary. You just need the little perpendicular pin near the end to grab the cogs. Without measuring anything, I bet this one may work: https://www.ebay.com/itm/FORD-MODEL-T-HAND-CRANK-STARTER-HANDLE-29/382346939025?hash=item5905a74a91:g:9LoAAOSwcj1aMbgw&vxp=mtr

    Hand crank for a 320?

    I have an original from my 320, but not for sale. You should be able to use one from a Datsun Roadster or MG as well (may have to double check whether the bend is in the right place, but I know the end will match up to the 320 crank bolt.)

    64' Datsun 320 Field Find

    I've got a J13 in my L320, and I'm not terribly far from you (Southeast Ohio). I didn't do the swap, was like it when I got it. The truck came with a whole box of various engine mounts/brackets, which I've never determined the reason for them. I've never driven one with another engine, so I can't compare. The J13 is close enough to stock that most people can't tell the difference. The alternator sits a bit too close to the battery, and the air cleaner rubs the hood prop. Both things that could be easily resolved, but I just don't care that much. It still looks basically like an MG engine, still get the cool viewing window into the float bowl on my Nikki carb, and I can still use the hand crank starter (had to source a crank bolt from a Datsun roadster for that). I've put around 25K miles on mine since I got it over 6 years ago. Quite slow, but hauls damn near anything I can fit into the bed.
