SadieD Posted November 9, 2014 Report Share Posted November 9, 2014 Hi everyone, I'm new to this forum but I've been peeking in since I picked up (or rather had dumped into my driveway) my '78 eggshell white 620. The truck has a pretty clean body, not too much rust, and a complete interior. It wasn't in running condition however, the engine turned over so good enough :) I've been working on it for the past few weeks, pulled most everything out of the engine bay, sans block. So far, the carb's been rebuilt, valve clearance adjusted, new intake/exhaust gasket, new ignition parts, timing adjusted, brake lines replaced, new radiator, many new emisions parts. Today I worked on the hood. The original mounts for the hood hinges were rusted solid and beyond hope. So being a machinist, I made a new pair out of aluminum. Here's the cad model, the other mount is a mirror image of this Machined and installed The mounts work perfect, the hood aligns proper. 4 Quote Link to comment

cubadomingo Posted November 9, 2014 Report Share Posted November 9, 2014 Beautiful pick up. Those hinge mounts are nice, I can most definitely see others wanting some. 1 Quote Link to comment
SadieD Posted November 9, 2014 Author Report Share Posted November 9, 2014 Thanks! I guess if my truck's mounts were so badly rusted out, in California, that others might have the same problem. If anyone is in dire need I can make more for the cost of materials when the machine isn't in use. Here are a few more pics with the hood mounted. I'm going to try to start it today, fingers crossed that my cobbled together carburetor was reassembled properly. I'm almost sure that the choke linkage is wrong, and I haven't figured out where the throttle cable is supposed to mount : / Quote Link to comment
red13 Posted November 10, 2014 Report Share Posted November 10, 2014 how much then for the mounts? Quote Link to comment
banzai510(hainz) Posted November 10, 2014 Report Share Posted November 10, 2014 IM not getting how these mounts work? as I see where the hood bolts to the lever with the 2 holes.but i dont have a 620 so cant see how its works altogether. if you have spark at the coil. timming is close got fuel to the carb and you see it squirting in the carb its most likey going to fire off. Most times the carb is dry so it take a while to get gas up to the carb so soem pour a little gas in carb. what I do is take the mechanical pump out and pump it up by hand then reinstall it. But up to you. Quote Link to comment

Yea, they're kind of strange. The U shaped arm feeds through a hole above the firewall then another below the windscreen/above the wiper arm assembly. Here's how they look stock. I guess I can make a pair of mounts for $30 +shipping. 1 Quote Link to comment

Hrvat9 Posted November 14, 2014 Report Share Posted November 14, 2014 Can I ask how you took them off? I thought they'd just slide off ,but they seem welded on ? Quote Link to comment
SadieD Posted November 14, 2014 Author Report Share Posted November 14, 2014 Can I ask how you took them off? I thought they'd just slide off ,but they seem welded on ? They're spot welded on, but mine were pretty rusted out, and the previous owner had already removed one. I pried mine off, then grinded the area a little. Quote Link to comment

heretic Posted November 17, 2014 Report Share Posted November 17, 2014 welcome hahaha rad hood hinge mounts.!! good looking truck Quote Link to comment
SadieD Posted December 6, 2014 Author Report Share Posted December 6, 2014 So I got it started finally, but I had to get a new distributor to make it happen. It smokes pretty bad but I know the carb isn't adjusted properly and the catalytic converter is toast, so fine tuning at this point :) Quote Link to comment
SadieD Posted March 10, 2015 Author Report Share Posted March 10, 2015 I've given up on the old carb and got a professional rebuilt. It turns out that the one that came with the truck wasn't the proper one. I've re plumbed the vacuum system and replaced worn out emissions parts. Right now I have the exhaust system removed from the cat back, just waiting on a new exhaust and some adapters before I get it welded back together. I also found some bad rust on the forward part of the floor pans so I'm gonna cut the rotten parts out and weld in new sheet metal. Oh, I also put new tires on, rebuilt the rear brakes, replaced brake lines and shoes on the front and bled the system. It won't be long now. 4 Quote Link to comment
rharm78 Posted March 12, 2015 Report Share Posted March 12, 2015 I feel your pain, my 78 620 never wanted to run. It was a process of elimination until about july of last year when I got it smogged and registered 1 Quote Link to comment
rharm78 Posted March 12, 2015 Report Share Posted March 12, 2015 Is your truck a longbed? Its funny because my truck is the exact same color and everything, but a longbed Quote Link to comment
SadieD Posted March 15, 2015 Author Report Share Posted March 15, 2015 Is your truck a longbed? Its funny because my truck is the exact same color and everything, but a longbed Yea mine's a longbed too. I just discovered the mechanical fuel pump is dead too, I've been running it on a gravity feed can until now, so at least a couple more weeks. 1 Quote Link to comment
SadieD Posted April 1, 2015 Author Report Share Posted April 1, 2015 The fuel system is working now, and it idles great but bad news, the piston ring on cylinder 2 is allowing oil to blow past. It looks like I need to pull the engine and do new rings :( Quote Link to comment
SadieD Posted April 4, 2015 Author Report Share Posted April 4, 2015 It turned out to be stuck rings. I tried Sea Foam, then PB Blaster and that stopped the blow-by. 2 Quote Link to comment
SadieD Posted April 25, 2015 Author Report Share Posted April 25, 2015 Welded in new sheet metal for the rusted out driver side. It was my first try at welding, don't judge me! I also had to replace the wheel cylinders on both rear wheels after discovering that they leaked after bleeding. 3 Quote Link to comment
SadieD Posted April 29, 2015 Author Report Share Posted April 29, 2015 I drove it around the neighborhood today for the first time, then I found out that it needs a new clutch... but I'm happy The steering feels pretty loose too, I need to look into it. 1 Quote Link to comment
red13 Posted April 29, 2015 Report Share Posted April 29, 2015 Dont take the box apart its no fun putting it togther. Try the adjuster screw on top of the box first 1 Quote Link to comment
SadieD Posted May 3, 2015 Author Report Share Posted May 3, 2015 Dont take the box apart its no fun putting it togther. Try the adjuster screw on top of the box first Thanks, there was enough adjustment to eliminate most of the slop. I checked for binding while the wheels were up in the air, it seems good. Right now I've got the drive shaft out and the transmission backed away enough to have the clutch and pressure plate removed. I'm having trouble getting the transmission to drop out completely, is there a trick to it? 1 Quote Link to comment
