ACSD removed

[Splittilps]

The truck is in getting a makeover so I finally got around to removing the ACSD. It was easier then I thought it was going to be. I am in the middle of a front axle rebuild so I did it all from in the wheel well. So here is a little right up on how I did it.

I picked up the plate and o-ring at a local injection shop for 5 bucks. I had the parts numbers but none of them seemed to work. I just described what I wanted and they knew what I was talking about. Got about a foot of 3/8 coolant hose and some clamps and I was ready.

The Start:

First I took off the bottom line of ACSD, Took the clamp off and then I cut the line to get it off. I had the new hose ready to put on so it didn't make too much of a mess.

Next I did the same to the top line:

Then I remove the ACSD: 3 bolts.....

This one was a bit tricky:

If this bolt didn't strip I would have had it all done in 45 min. grinding it out.......

Finished...

Now I feel much better. Now I just need to finish everything else………….

I know this has been done before but maybe this will help someone.

Cheers

Good write up. I was a bit confused if I ever had to do this because people were talking about it.
This clarifys everything.

After I read a few post like this:

Blanking plates... the ACSD is a liability you might want to get rid of. Blanking plate and seal will run about $25. Not removing the ACSD, about $2500 + labour.

I am for removing the ACSD.

I decided that it was a good move and the best 20 bucks I have spent in along time. Now I don't need to worry anymore!!!

Nice pics and write up. I was going to post some pics, but never got the photos from when I did my friends truck. I think your pics are a lot nicer, my friend had his phone camera. Mine was about to go, and found metal flakes on the ACSD opening, and over flow. Eventually I had my pump rebuilt. Now, I use my throttle lock to warm up my engine when cold, until I hear a click, and the idle goes up on it's own.

Could you post a pic up of the blanking plate washer or gasket that goes behind it? My spanish is OK but trying to explain to the local Bosch/Denso shop that I want to remove something that is working perfect in case it breaks later is going to be tough.

TBH if one of you guys know of a kit I would rather order it and be done and dusted, I would have to travel about 40 odd miles and the time and effort ect only to be told we do not have it might be worth the shipping?

Let me know please?

sorry don't have any pics of just the plate or the o-ring. i know some where someone was putting kits together but i can't seem to find it right now.

cheers

OK thanks, I will have a root around with the search when I get five minutes.

i haven't looked at my dads (I am out of town)
do the 1hz have an ACSD?

 

[VE7PGE]

Just got all the parts from Fred Holmes Fuel Injection Ltd. in Richmond, B.C., Canada
(tel 604 273 7700)
they have all the parts and new bolts, the blanking plate looks to be 1/4" thick, now just need the time to do the job.
What size is the allen wrench? to remove the old bolts.
Bosch part no. cover plate 1461 074 312- 770, O ring 2 460 223 001.

 

[Dave 2000]

I cannot remember the correct size for the allen key however, the bolts can be real tight so purchase a set of good quality.

Hi did you had to retime the pump after removing the ACSD?
Thanks

 

[ForealBoreal]

you should yes.

 

[pandore]

Thanks but I don't understand why since the ACSD is'nt supposed to do any action when engine is warm?

 

[ForealBoreal]

Mine was right out after I removed it.
Talking to a well known cruiser mechanic he recommends retiming it also as its usually out.

 

[pandore]

How did you knew your pump was out after removal?

I have the parts here but am in a bit of a pickle as I may have mentioned before. If I take the ACSD off... Denso, the only local specialist that can reset the timing won't touch it as the pump will have been "modified". Doesn't help being way out in Bummfeck Japan but I can't find anywhere else that can do it. I've watched the video of the Aussie guy timing the pump but I'm not sure I'm up to sourcing the SST equivalent parts to try doing it myself.

 

[pandore]

I've brought my truck to a local diesel shop last summer because my engine was making white smoke and had a lot of hesitation and they timed (I think they gave more advance on the pump) without any special tool just by rotating the pump and watching and and hearing how the engine was going. I would say they made it only by feeling without any SST.

 

[Squash]

B. if the engine is running fine just blank it off and be done with it, otherwise have the Denso specialist install a new ACSD and you are in spec.

My bet is our colder (Canadian) climate contributes to the ACSD's demise because it takes a long time to warm a diesel up at - 20C, -30C, -35C and the ACSD is trying to alter timing until the engine is up to operating temps or the ACSD eventually gives up.
Think of how your glow system is bypassed when the engine is warm.

My HZJ79 has no ACSD and will start at -30 without using the block heater if glowed properly.

Again if your engine is running well just do it!
