    found an aluminum truckcraft flatbed for a great price and grabbed it. its going to replace my cheapy steel flatbed. i would really like to make this bed dump since it is plenty strong enough to hold up to it. i have been thinking my truck already has enough work to do electrically and my np205 transfer case has pto provisions. what all would be involved in getting that going?

    Well for probally ease I would say electric over hydraulic. Way easier to deal with and install

    It would work fine.Your tranny simply needs to be in neutral upon PTO use.

    Unless you plan on simultaneously raising the plow and the bed, I don't think you're looking at any issue with how much work your truck has to do electrically. Electric dumps are just so much nicer to work with and have no real disadvantages...it's not like automatic vs. manual transmissions where you get real advantages for little extra work.

    Use all that extra energy and garage time to swap out that slushbox for a real transmission.

    If you're doing a lot of dumping a pto cycles faster. Also my truck is an auto and you just flip a switch and dump. No need to be jn neutral. That would be a dealbreaker for me as i always need to pull up while dumping

    all our pto autos,,,can be in drive or reverse with the pto on. to engage it, out in d or r pull pto level, the n to operate bed

    Should have elaborated more.Depending on what your setup is,and whether a Muncie or a Chelsea PTO is being used,usually having your tranny in gear while engaging or disengaging the PTO,then put the tranny in N.Best to follow manufacturers directions though--lots of different possible combos out there.

    As far as slush boxes that was one thing Dodge could do really well.

    Muncie is also a major player in PTO's.

    alright unfortunatley cost is killing this idea im gonna have to go electric even though thats not my preference... new question, the hoist is rated for 3200 psi so i am i correct to assume i should get the closest to 3200 psi pump/motor i can find? would this make for the fastest dumping?

    ok cool im not that knowledgeable with this stuff its kinda new to me. what should i be looking for in the pump? highest gpm? would that make for fastest dumping? am i worrying about something very insignificant here? if im only going to lose like 5-10 seconds thats no problem i just dont want to be sitting there waiting for the bed to dump for minutes. also how do i know what size reservoir it should have?

    just some corrected info for others .

    if you have a pto on the t-case then tranny has to be in a gear . or the internals of the tcase wont spin and run the pto on the tcase. but put the tcase in n position as it will spin the pto of the input gear teeth .

    and watch your self on pto drives on tcase . if you run tranny in to tall a gear you can over spin the pto driven item or if reverse can hurt somthing if not made to run in reverse.

    lots of off road guys do a tcase pto drive for inbed winches to give them line speed in forward gears and reverse power out if tranny is put in reverse.

    You can calculate the fluid that the cylinder will hold based on the diameter and stroke of the unit. Also, it matters if it a 2 way setup (power up power down). If not, you can set up the top of the cylinder as an extra reservoir, but sometimes that can be a PITA.

    im going to use gravity down. thats what my dump insert had and came down plenty fast i didnt have to wait for it long and i figure thats less wear on my battery and alternator. how do i calculate the cylinder capacity?

    3.14 * ( .5 * cylinder diameter)^2 * stroke = volume
