After searching and researching my options for installing a dump hoist on my M923 I came up with all the components to install a PTO driven hydraulic pump and all the additional components to make the hoist and auxiliary hydraulics to run a dump trailer that I made from my 200 series generator trailer and a old 3 yard dump box I had on another truck. I thought it may be useful to someone to save a few bucks and see how I did the job. My total investment is in the range of $1800.00 including everything.
I chose to go with the PTO driven hoist because I want the option to run additional hydraulic operated equipment if the need should arise. I do also have a plow for the truck if I ever need to install it. I am sure I will be modifying my system as needed over time.
I purchased a wet kit from a person whom had it on craigslist after selling their m900 series and never installing it. Price was 500.00 and it was pretty much complete. Installing the PTO was a real job, It is a extremely tight fit and required a lot of trial and error to get it in the correct position. I did not have to move the trans in any way and no moving of mounts. The PTO drive shaft and pump was pretty much bolt in as was the controls and valve assembly. I did have to have a couple of hoses made to fit my system because the originals either did not fit or were missing. I am not sure everything is exactly where it belongs, but following the TM's and internet research I am sure everything is close to where it was designed to be. If anyone has suggestions or recommendations please post them. I did have to make a couple of brackets for the cables. The PTO control cable did not have one at all in the kit. The bolt that holds it in place is broken in the PTO and I did not feel I could remove it without doing damage to the PTO housing.
The hoist I used was purchased from a ebay seller whom manufactures trailer hoist kits. I contacted them and convinced them to sell me just the hoist. Price was just over 900.00 including shipping. The hinges were purchased from a internet seller whom manufactures them at a cost of 60.00 including shipping. The bed was removed from the truck with the help of a cousin and his large backhoe. I welded two 14 ft long pieces of 2" x 2" square tube to the frame rails of the bed for added strength and a bit more clearance for the hoist. We then placed the hoist in its final location, squared everything and welded in place. The remainder of hydraulic lines were run and fitted to the valve and hoist. Then the bed was placed back on the truck and squared. We fitted and welded the hinges on next. After hinges were welded we raised the hoist a little and determined its position on the bed frame. It was blocked in place and welded from underneath. (not easy to get to but can be done). After welding in place the bed was checked for operation then we fabricated the safety bar and welded it in place. Once the bar was in place and we determined it to be safe the bed was raised and all the welds and connections double checked and finished where needed.
I am sure there is more info I could provide and if anyone needs details on any step please feel free to let me know. I have been looking for the time to do a little write up in hopes of helping someone else wanting to do this, just have not had the time.
I am in need of a actual dump valve for this project if anyone has one available. I used the valve for the hydraulic winch, but it really does not work as well as it should and has no detents and a open center.
I will be posting a little write up on the trailer conversion to a dump as well when I have a few more minutes. I will post that in the trailer forum. It is complete and works very well.

. The hoist is a power hoist PH-516. Fully lowered it sits centered in the frame of the truck at its lowest point behind the rear axle. Above the axle it is about 2 inches below the top of the frame rail.
