    I do have alot of work to do, before I even do the work I have to do more work to build a gantry crane.
    I might cheap out and go to my property and cut down some 8" trees and make the gantry out of logs,
    or I can find some old bent pallet racking and make it out of that.

    TJ now with the power of a 5.2L vs 2.5L get same gas mileage....crap.

    I'm debating what type of bolts to get for frame attachment. I can get a set of four 5/8 grade 5 square u-bolts or I can get sections of 3/4 grade 5 or 8 all thread and cut steel base plates for under the frame out of some 1/2 plate.

    I got a larger 24v pump in, the pump I had on my shelves, only was good for 2.1gpm the one I just got in should be good for 5gpm so I should be able to run it at about 3/4 of its rated speed on the electric system.
    I also got in the 5/8" u-bolts and the hydro-max brake booster and master in. I have a remote reservoir coming in as.

    Now its time to build a temporary gantry crane to hoist off the bed, I'm thinking of making the beam out of two or three 2"x12"s bolted together with 4x4"s legs.
    Looks like a 2x12 can support 2100lbs each on a 10-12ft span with a .3" deflection so the main beam should be good for the 2098lbs of the crane.

    Well yesterday was nice out so I got a lot done!

    I was originally going to remove the service crane then move the bed back, and use a gantry crane to position the knuckle boom.

    But when I was taking off my spare mount and tool box I remembered I had a bunch holes in the bed from the tank and pump, so I decided to cut the front instead of the rear.

    That means I could use the service crane to move the knuckle boom, So I cut the front of the bed and pulled that of I then had to remove the out riggers from the knuckle boom since I need to fix the hard lines on them.\
    So three hours of drilling and burning off stripped and broken bolts I had the out riggers off, and the strange metric oring hydraulic lines, those are getting changed out to sae or npt fittings as soon as I can find a adapter.

    So it was 10pm and pitch black so why not grabbed a headlight and hoisted the crane down to the frame.

    Houston the crane has landed!

    Now I need to square it up I'm alittle off my marks from it being dark out. I'll need to put some angle iron supports together for the bottom of the frame to spread out the pressure from the u-bolts.

    Then its to make a big surplus center order for 1/2 and 3/8" hydraulic hoses.

    As for the pump I'm debating to use a single stage gear pump or a two stage pump for a wood splitter, the single stage I can size to the max flow of 9gpm (looking at main and return hoses 20mm and 45mm, I dont know if the manual was correct maybe they meant 19gpm) or I can get the two stage which pumps out 12-30gpm at low pressure 650 to 1000psi but switches to high pressure 2900psi at 3gpm.

    More pictures soon,

    I got the crane bolted down but the rear ubolts would interfere with the air tanks, but I found the mounts match up with the old bed mounts so I'm going to gusset that mount up and put in a 3/4" gr8 bolts in there instead of the ubolts.

    Now I'm welding the front of the bed back on. so I can get the old crane unbolted and I can start taking a sledge hammer to the bed to straighten out where the crane was.

    I also rigged up a temp hydraulic pump and the found the valves all leak enough, and they there are a few crushed hardlines that I didn't see.
    So I'm going to a 5 station solenoid block, with a wireless remote I got for the old crane and a backup wire remote station. I'm also going to remove the strange britsh/metric flat face hydraulic fittings from the hard lines and I'll tig weld on some 3/8" nps swivels, so I can use cheap tractor store hoses if I have to fix anything.


    Now I'm debating about my hydaulic pump again, I was going to put a 12hp gas motor under the bed and would run the crane for extended periods, and a 24v forklift hydraulic pump to run it for short lifts. Now I'm thinking of keeping the truck 6x6 instead of going 4x4 which would mean I will need to find another M35a3 wheel and bead lock along with more brake rotors and calipers, which are all going to be expensive. Or and can trade the M35a3 wheels for alumnium MRAP wheels and get adapters.

    Down side is staying 6x6 I have no room for the gas powered pump and I would need to use a pto pump so I would need to get a spicer pto and mount that to the transmission.

    What made you change your mind about going 4x4?

    I my cousin stopped by to check the progress and he got me thinking about the title saying it has 3 axles, and the next inspection.
    Now I know the axle is more than rated for what ever I could put in the bed, but I started thinking about traction, etc
    I hate when I start second guessing my self. Kind of still debating the 4x4 or 6x6 I'm still going back and forth. After unmounting and mounting these M35A3 wheels,
    I know I'll be looking for a set of MRAP wheel in the future, instead of these M35A3 wheels.
    The bead locks you need to hold the tires to the rims are a absoult pain, plus the alumnium Mrap wheels are 60lbs lighter each only about 250lbs total but 250 is 250.
