  1. Well if the cam is OK and all the valves just happened to stick at once, I think you should be looking at the oil supply to that area.
  2. Ah, that would be the cylinder right at the front then, immediately behind the cam driven gear? ( some people number the cylinders from the firewall end ... ) I think you have a broken camshaft, and the break is between cylinders 1 & 2, so cylinder one is opening its valves normally and giving some compression, but the other five cylinders are on strike - or at least their valves are. Hold the driven camshaft gear and try to rock it slightly - it should feel a bit more wobbly that you would expect - it may even pull out a little if you tug on it. The slightly less bad news is because you have a flathead / side valve, the pistons have not come up and wrecked the valves, which is what would have happened with an overhead valve engine.
  3. I'm thinking something simple but not obvious, like a broken camshaft, or camshaft not driving
  4. If this was at a barrage balloon site, I'd think the vehicle with the tank would be there to scavenge the gas when they brought the balloon down, rather than waste it. The unit behind the cab would be an engine driven pump.
  5. I don't think so. Those hubs would have metal and wood centres and the load of sighing them there might be problematic. If I'm seeing that right, the spoked wheels are just acting to retain the lifting ropes, which go through the wheel spokes and presumably under the axles. If you were lifting from the outer grooves on the hubs it would be near impossible to keep all four in place long enough to get a safe lift.
  6. If they are all branded as USA made I'd stick with them. You can of course buy a complete new set of high quality bearings, but that may cost a surprising amount. Spend some of the savings on seals, axle end gaskets, and the like
  7. I'd stick with those if they are in good condition, US-made bearings, and the low sequence number suggests they may be original. Where did your truck come from, or via? If it is straight from the USA or via Norway, those are probably higher quality than many modern replacements.
  8. If it was free to pivot in the chassis brackets it would be fine. Trapping or restricting it wouldn't work - the first time something bottomed out it would shear. I'd guess both sides would pivot freely - it would help the high-speed cornering too. 🤐
  9. It looks like it functions like a cross between a torsion bar and the worlds slowest anti-roll bar. 🤔 plus it would add greatly to the rigidity of the rear end.
  10. Very nice. It will look great when the rest matches, and I'd be surprised if the original paintwork didn't have the odd run too.
  11. Interesting that the die is marked NS, National Special, rather than UNS, Unified National Special, so it is liable to be as old as the thread you are gauging. That's probably why it didn't say UNS on the advert too. I wonder if those endlessly complex trade laws would stop you making and selling something like that as NS these days, with only UNS permissible?
  12. It looks like you could use the Martian type. The male threads would match both ends, they have just substituted a coarser thread where it runs through the bumper to a locknut, so one coarse thread locknut and you are done. It is quite possible they went to a coarse thread at the bumper bore transition exactly because the fine thread locknuts used to seize up and strip all the rest of the thread - just like yours did.
  13. While I'm on I think that is the original head too - be great for a paperweight. 8-)
  14. Well good luck with it. If you get stuck just drop any other flathead six Chrysler in, they will all fit. Don't throw that one away though, as the chassis it came in is still driving in Scotland.
