ACSD: The Mysterious device..

[sandcruiser]

I finally managed to find a block off plate by going to an injection pump shop (Laboratorio de Diesel). The lady behind the counter informed me that, no, they don't sell parts.

But she eventually warmed up and a tech who was there offered to look through their junk pile to see if a pump had a plate on it. Apparently something worked! An hour later I called and she said that they did have a plate. Which was great as I had already checked 4 parts stores (all of the parts stores in town) and nobody had IP parts and none were willing (able?) to order anything.

So I'm stoked. I was going to fit the plate tomorrow morning, but a good friend mentioned that longer screws are a good idea as the ACSD mounting surface is thinner than the plate, and the aluminum pump body might not hold the threads unless I get longer bolts. Sounds like a good idea! So I'll dig through the random spare connectors that I have, or buy some more bolts tomorrow and get this sucker installed.

Sidenote: the plate was free. Which is always nice. But I'd rather that they stocked parts and sold them as I probably burned as much fuel hunting around as money I saved by getting the part for free.

They used Torx screws on mine. Other members reported using Allen screws (longer than OEM ones as you mentioned). I guess any will work. Sorry, don't know the exact size..

can you share the bolts info when you get 'em installed and what are you planing with the cooling lines from and to the block . ?

 

[sandcruiser]

I bought some 3/8 heater hose, I think it will fit. I'm just going to make a single loop for the water.

someday I may plumb a veggie oil heater there. but not now.

Here's the part number for the hose connection that you can use to join the coolant hoses after removing the ACSD:

Napa P/N : NBH 9902

I bought it but did not install it yet, so take my advice with a grain of salt. But I know for sure that the O.D. of the ACSD coolant hose is 5/8" so I am assuming the ID to be 3/8"

The link didn't funtion and the part # seems to be wrong in the napa web catalog

Napa website is a bit stupid. It only gives you a temporary link with a timeout period. If you don't go there within the specified time, it will show it as "Expired session"
In addition, it does not allow you to search using Napa part number (their very own P/N!) on their main site.

Here's what to do:
On the left hand column on their web page website (a couple of lines below the ZIP code entry block), press "Search Napa Catalog Using parts Pro SE"
It will take you to another page (looks totally different from the first one). There you can search by part number (make sure you choose Part Number as your search criteria)

Hope this helps..

I got it .. ! thanks ..

maybe there is something like but in U ?

 

[sandcruiser]

Arrrgh!
One of the allen head bolts (the long one that goes through the idle up lever) stripped out. Can't get vice grips in there due to other components.

I slotted it with a dremel, but can't really get an angle on the screwdriver.

If you do this job- be sure to hit it with wd40/pbblaster before you pull the bolts. Mine were stuck pretty tight.

Going back out to see what I can do.

Good news, bad news:

I finally ground the head off of the bolt that wouldn't come out- I'm not re-using it anyway, so it was an acceptable solution.

Wow! When people say "a little" diesel comes out.... it was more like a cup or more of diesel that poured out when I pulled the ACSD off. Big mess. I had a rag under to catch the "little bit" but a bucket would have been a better solution.

I didn't need new bolts- instead I used the two bolts from the fuel advance lever bracket, which are longer. Then I used the shorter bolts from the ACSD to put the bracket back on, and they seem long enough to do the trick.

The acsd bolt is on left, the idleup bolt on right.

I used about 14" of 3/8" heater hose to connect the two barbs on the block and bypass the ACSD coolant line. A foot is probably enough hose. I re-used the clamps that were on the old line. I guess it would be better to use fancy clamps. We'll see if it leaks.

Used blue loctite on the bolts for the plate and the idle up bracket. Just to be safe.

Now for the bad news: it seems my manual primer pump is not doing its job. I pumped for 20 minutes straight. Nothing.

So I'm off to buy a new fuel filter as I don't have a wrench to pull this one and I'm afraid of damaging it. I'll put the new filter on, full of fuel, then try again to prime.

another note: you'll lose a bunch of coolant out of the lower hose barb.
If you plug the upper barb (I used my finger) the coolant flow stops, then you can slip the lower hose end on and thus stop coolant loss.

Also: pull the the top hose off of the block, then plug, then pull the bottom hose, add new hose, then connect on top. If you do it carefully, you shouldn't lose much coolant at all. I lost a lot. It is now on the ground with the cup or so of diesel that came out of the IP.

Thanks .. I never had a problem with my IP but I woudl remove one of these days the ACSD to know if something change on my injection ..

 

[sandcruiser]

if ain't broke.... I'd leave it alone. It is an easy job (mas o menos) but if your truck idles well there may be no benefit to pulling off the acsd. Although it does make the truck more simple, and maybe more reliable.

if ain't broke....

ain't fix it ..

Don't worry .. I have a huge list of things to do on 3 Cruiser for a while .. including my tranny swap .. so I'm not planing do it soon ..

Actually I'm thinking right now in my weekend ( Carnavales ! ) camping trip ..

here is another photo of the ACSD blockoff, complete.

seems that something isn't quite right with my fuel filter/primer pump as it took a lot of work to get it primed again-- I had to pull the filter assembly off and turn it upside down to get rid of air in the system, then blow compressed air into the tank while turning the engine over, in order to get it to fire up. PITA, but it finally works. No rattle on startup now!

 

[Cancruiser]

Thanks for posting this Sandcruiser..
I found that you have to pump like 1000 times to get rid of the smallest amount of air. So, I guess what you experienced was normal..Glad it all worked fine for you..

 

[sandcruiser]

yeah... I don't think it was actually "normal" unless normal is a POS primer pump. I'm pretty sure that the pump is just worn out and/or needs some sort of rebuilding.

I'm planning to add a 12v pusher pump near the fuel tank to help in the future, as I've been led to believe it may also extend the lifespan of the IP's lift pump anyway.

Steve .. install a cheap inline fuel pump with a switch .. save plenty of time in the priming process ..
