Dump bed install
i am about to start working on my 1989 F-superduty. I am removing the dumping stake body from my 1988 f350 and installing it onto the superduty. both trucks are manual trans. superduty is 7.3, and f350 is 7.5
I have two questions.
1. can I install the pto from the f350 and install it onto the superduty
2. I plan on installing a knuckle boom behind the cab. how would this effect the pivot point on the dump bed. I know the bed will sit 2 feet further back and the rear will be lower as dumping. Right now the pivot point is 6" from the rear of the bed.
can I move the pivot point 2' from the rear? or do I have to install a subframe. Any advice will help and will be appreciated. thank you

I see these trucks with rollback beds and 14' dumping stake beds that over hang the rear axle by 4-6 feet. I never went up close to look to compare. but are the pivot points for these beds at the rear of the bed or is it behind the axle still?

You can move the pivot point 2' further forward on the body, but there may be a problem if there is enough room to mount it. I know on my F550, there was no where near enough room to move the hoist 2' forward. MAYBE 1' but not 2'.
You will have to break out the ruler and see if you will have enough room.
If I was you I would be long for a longer wheel base truck, or lengthen the one you have
As for rollbacks and 14' stake trucks, they typically have the longest wheel base available to accommodate the bigger body.
here is my old lumber delivery truck. It had the LONG wheel base AND the 14' body. The long body allowed the tail to come closer to the ground to not let the wood SLAM into the ground when being dumped

oh yeah i see.so a setup like this:
^that would be really handy right there but man,you really lose some room.
yeah,so you really need the long wheel base like Brad says,like my f-sd but with a short bed to get the room.
according to an online vin decoder it says the wheelbase is 298" on mine:
that will take a 16' log.^ i can't wait to outfit mine but im not finding any of the stuff used come up yet.

hmm.yeah,right Brad.
298" is about 25' and iv measured the whole thing,and i think the whole truck,bumper to bumper was about 25'.well dang,i did measure center to center on the wheels but i forgot now.(i recall measuring the bed.i know this is exactly 16') i'll have to toss the tape on it again tomorrow (and check door jam.i didn't know wheelbase was on there.) and make sure i write it down in my records this time.

well you know,i thought this may be have been extended by a truck shop:
do you know if thats how they did them at the factory? or is that for sure done outside from ford? cus i was talking with a guy in the idi section with a shorter one and he said his frame (f-sd) was sectioned together exactly like it.
(the two tubes of course are just for the dump bed.unrelated to the extension.)

yeah thats what i thought.ill run a tape between center of the wheels again tomorrow and make sure i write it down this time.i figured when ford made the long wheelbased f-sd they would have just made a bunch of longer frames and not extended them.this is what i figured.im the 3rd owner and the guy i bought it from said he didn't have it done,so it was the owners of a tennis court who bought it new must have took her in.
anyway,this is what bigray really needs done to his to fit in his boom.boy,im not sure id want to see the bill.wiring needs to be extended,fuel lines,frame of course,drive shafts.....oh boy.

Thank you for the input. I do not want to go through the process (or cost) of extending the frame. I collected all these trucks and equipment for cheap over the past few years. I would like a newer truck with all this equipment, but I don't use it daily enough to buy a new one. And this truck is great, low miles and strong. I plan on keeping it for the next 20 years. I also have a rail-mount lift gate on the back of the dumping stake body.
But would I be able to have the center of the bed over the rear axle, or
Could I extend the rear of the frame, beyond the suspension/spring mount. And install the pivot hinge 12" further back. ( right now the hinge is directly behind the spring perch) or
Would installing a sub frame on top of the frame, and have the subframe overhang by 12" or so. I'm not sure if this would create too much stress for the overhang (even tho I see many sub frames Overhang past the frame) like on other dumps and box trucks.
I really want to make this happen with the truck I have. I would prefer to extend the frame 12" back, if it will support the dump hinge. Thanks again

I have visited many other sites and manufacturer install recommendations, and some of them allow 12" or 24" or 36" overhangs. Going by the manufacture specs, this will be perfect. I want to know if the truck frame can support the weight tho, since the hinge will be about 12" further back.

Like in the second pic posted by fordf250hdxlt with the 16' stake body. Would you be able to make that bed dump? Since the frame extends several feet past the rear spring hangers. Will the frame support the weight at the rear with that much overhang? It's more than what I need, I may only need to extend the frame 12", but this is similar to what I want to do.

if you only need another foot to fit your boom in between the cab and bed,you shouldn't have any trouble extending the frame back i wouldn't think.
