@jpsfj60, have you attempted the ACSD delete yet? I'm wondering whether the replacement hex key bolt size for the backing plate (post-ACSD removal) that the Radd Cruisers representative suggested is correct (6mm x 1.0), back on post #11 in this thread?

Also was told to hold my
pedal to floor for the 1st start up after this job is done. The reason for that is cause of the diesel
fuel you loose when you take out the ACSD from the IP.
I don't really think that is necessary.
Sorry was told to do that after it shuts off from the air in the fuel system. Will let everyone know
if it shuts off like my buddy says. He is a trained diesel tech and have built many of the best diesel
engines in the world. THE CUMMINGS!!! Wish this 81 had a 6BT in it instead of this 1 HDT. Wouldn't
be doing this delete if it was a Cummings. I would be doing a Denny T top hat delete that adds 90 HP
with just one simple mod!
That, and the killer dowel pin, lol!

So you did it and no mess with timing ..?
Thanks @jpsfj60!! Did you take any photos as well? If not, no worries, your explanation seems great without any photos. I have a manual (5-speed) and no cruise control, so I won't have some of the items you have to remove to get to the ACSD. I'm also wondering whether I should just go and buy new 5mm hex key bolts of the right length for attaching the backing plate. Do you remember the length and size so I can go to the hardware store and get some? I don't have the luxury of assuming that I'll have the right length 5mm hex key bolts since our HDJ81 is our only vehicle and our daily driver If you know a size/thread type for the 5mm hex key bolts that should be used to hold the backing plate on, that'd be great!
The coolant line hose how-to portion is great as well...I was wondering what the order should be so that I don't lose a bunch of coolant and make a mess. Thank you for posting your experience on the ACSD removal...huge, huge help!
I will try and add to this thread with photos when I get around to my ACSD removal. I have the new o-ring and backing plate, along with about 16 inches of 3/8 inch coolant hose and two new clamps (for looping the coolant lines after the ACSD removal).
The Radd Cruisers ACSD delete kit also included some dowels to space out the bracket from the pump where the ACSD used to occupy, although it took a bit of pondering to figure that out as the kit didn't include any instructions.
image of that kit ?
