Tearing down my HJ47 troopy (2 Viewers)

[cult45]

So I checked toyodiy.com and this is for your HJ47. Vents to atmos only by the looks of it.

I'm pretty sure that is the petrol return line-not used in the diesel.

I'm not sure that's true HJ47. I think it is simply the evaporator's gaseous vent, and no fuel is intended to be going through there, unless you turn the truck completely upside down or on its side. It's just a vent to the outside air, and the check valve further up the pipe keeps water from backing up into the system if you partially submerge the truck. This could be confirmed by blowing into the pipe to see which way the check valve works.

Interesting, my note on the tape wrapped round the hose coming from this check valve read "into frame" . So, it appears this is a vent for the fuel separator, but how weird is it that they thought exiting it into the frame was a great idea. Seems odd!

Today I got out the hard fuel lines and fuel pump to begin cleaning and re-installing. I may order a new fuel pump simply because this one might be 32 years old. It worked fine before the tear down, but if its not too pricey, I'll get a new one.

I suspect they put the outlet inside the frame to make it less likely to get plugged by dirt.

Now that I've got the protector plate / rock shield for the gas tank out, I see there are no bolt holes. And looking at the diagram, it appears the protector plate goes on the tank before the straps. I could barely get one of the straps on as it was, I can't imagine getting it on over the rock protector. I have shims that were for the straps, but, my God, I have to take the straps off and start over, I guess.
This is a WTF moment ! The tank is flush against the body now, so I can't imagine the straps working over that rock shield. Obviously they did, so what the #&$@ am I missing?

Here's a pic of the fuel tank protector (nicely painted). So I just have to find a way to hold the tank in position while giving me access to re-mount it with the protector plate. Or more likely, I have to disconnect the fuel lines and filler hose and drop the tank and start over. If the glass is half full, I'm the guy telling myself it'll be easier the second time around.... I'm not that guy, the glass is completely empty!

Yeah, getting that tank in place is a bit of a juggling act. The tricky bit, IIRC, was just getting its irregular shape into the right mounting position and holding it there so you can get the straps on.

 

[gswest]

I used the transmission jack the first time, but the one strap is definately harder. I used a longer bolt and three shims. We'll see if I can get it on right today without having to disconnect any of the hoses.

 

[gswest]

As maybe you can see, I finally got the fuel tank protector plate on with the tank. It wasn't too difficult after all. I didn't have to remove all the hoses and clamps, I just removed one strap off completely and the other one off just partially. Then I was able to squeeze the tank and plate in and get the straps back on and connected. Every day is a small battle, but any victory is sweet! You can see my exit strategy there,,the chain saw!

Did you rhino line the tank? I must have missed that. Looks nice!

 

[gswest]

No, that's undercoating. I just touched it up a bit after degreasing the whole tank. The top is in black engine paint. I cleaned up the sedimenter and painted it and the bracket. I'll probably sand it down and put another coat on it becuase of some bubbles showing in the paint. I mistook this part for a fuel pump.
I'll figure this diesel stuff out eventually.

 

[Henry James the 47th]

Did you pull the bleed screws out of the sedimenter to be sure they weren't rusted in place? It's worth doing if you haven't already.

 

[gswest]

Yes I pulled the bleed screws out. The top one was difficult, but I got it out. I guess I'll flush it with some diesel before reinstalling it. I wonder if I should fill it before attaching it. Might it make priming the injection pump a little easier?

Yeah, that's a good idea, and ditto for the fuel filter.

 

[gswest]

Does anyone have a picture of the hard fuel line and sedimenter position? I've mounted the first hard line which crosses from the tank outlet to the fuel pump side and faces downword. Obviously a rubber line connects to this section, but the other hard line section connects to this and brings the line up to or closer to the fuel inlet on the pump. This is another one of those "I should have taken a picture" moments. I mounted the sedimenter in a spot that seems correct, close to the pump, but I'm not positive. I could just run a soft line to connect these parts, but I'd like it to be correct. I'll take a picture latter to show what I have so far.

 

[Henry James the 47th]

Here's a pic from my build showing the sedimenter bolted to the frame. Hope it is of some help.

 

[gswest]

Thanks, I'll try that location when I get home tomorrow. I'm sure it will help. I see the hard line connecting to the short rubber line. That's what I needed to see.

 

[gswest]

I'm going on 48 hrs with no internet connection and TV; thanks ATT U-verse. So I can't attach pics with my Droid tablet yet, l haven't figured out how to do that. But, I did get the fuel line attached and I reinstalled the vacuum tank. It sits next to the sedimenter (thanks HJ the 47th). This tank doesn't show up in my manual at all, so lm curious if every HJ 47 had them, and what exactly does it do? I'd assume it stores pressure or vacuum pressure. I know Henry James can answer this, so give me a clue brother. I have one outlet coming from the vacuum pump/alternator. Where does the other line on the tank go? Again, there is no diagram in either manuals I have. Still waiting on the allusive electronic manual from Australia.

 

[Henry James the 47th]

The vacuum reservoir is for the brake booster, and provides reserve if you lose engine power while, say, going down a long hill.

There are two fittings on the tank, one coming in and one coming out, and a pressure switch (sensor) on the back. Of the two lines coming in, one comes directly from the alternator pump, while the line coming out goes to the brake booster. You can tell which is which by blowing in/ sucking out, and see which one allows air in but not out. That is the one which takes the air from the pump.
