So lets talk about that hinge.
This is how its designed. One bracket that bolts inside the frame, one that bolts to the bed, and a 5/8 Gr8 bolt for a hinge pin
Frame side bracket. Not thrilled with this piece. The bushing is a nut with the threads drilled out, but its oversize so the bolt is sloppy
Bed-side bracket. has this angle iron tab that extends forward to tie into the next forward bed xmember. Good idea, but it doesnt fit on the 92-97 bed, so its gotta go
so here's the new bed half. Not a fan of this as the hole on this is also oversize so the bolt is sloppy.
At this point i figure i had two options. Use their hinge and upgrade to a 3/4" bolt for a hinge pin, or just build my own hinges. So i looked it up. According to this page, a 5/8 Gr8 bolt has a shear strength of 27,920lbs! Clearly i dont need a 3/4" bolt for the hinge, and the 5/8 will fit in the space better. So i guess im making new hinges!
Ok, gotta make some spacers. Carbide holesaw in 3/8" plate
New hinge, with spacer welded in place. All 3/8"
Installed on frame. Unlike theirs, mine uses all existing holes in the frame. Also of note, i need to finish trimming the frame. That notch is required for room for the hinge to pivot.
...and the comparison between mine & theirs. IMO, mine is far superior.
So now i need to build the bed-side half of the hinge. Well, i scrounged up some more 3/8" plate that im going to use to build them this week. I really liked the idea of making the hinge double shear, but there just isnt any room under there to do it with the hinges built as such; i might have to make a second spacer to weld to the inside of each frame-side hinge, but these will most likely need to be 1/2" in order to space them far enough away that they will not interfere with the bed bolt. So my goal for next week is going to be to finish the hinges, as long as mother nature cuts me some slack!
One thing i want to say. Im not trying to bash on Pierce-Arrow. These guys have been building these kits for, as far as i can tell, 15-20 years, and everyone loves them. No complaints from anyone on the parts that ive found, which tells me that if their sloppy single-shear hinge is good, then mine will be better. Also, it doesnt have to be double shear, but if i can i want to do it, just cuz i can. The scissor for the hyd cylinder seems like a nice piece, as does the pump, and the wiring & hardware kits are both nice as well. So basically, my only complaint with it is the hinge, which will soon be resolved.
let the upgrades begin!
So i have a small update: rain sucks. It wont stop! We got ~12" of rain last week, with more coming next week! So i do have some real progress, but thanks to mother nature its been slow.
Youre probably wondering why i lifted the bed to do all that work, when i couldve done it all w/o removing it. Well, it has something to do with this:
Youre looking at a 2ton hydraulic dump conversion kit.
It converts the stock truck bed into a covert dump bed, which is pretty awesome. Bought it last fall and with working on the green bronco never got around to installing it until now.
It came with a ton of Gr8 hardware
a whole bunch of wires, connectors, 200a circuit breaker, hydraulic hose & fittings, all sorts of parts
the pump is a pretty nice piece, and has a built in 3qt reservoir. Its designed to run on ATF which is convenient.
So here's where i goofed. This kit is a 'universal' kit because it fits like 20 years of these trucks. As i later discovered, there was a specific kit available direct from the manufacturer (Pierce Arrow, Inc) that wouldve worked better, but oh well. The primary difference is in the hinges, anyway, which ill get to in a moment.
So i need to notch the end of the frame for clearance for the hinge. This is the point of no return, as im also cutting off the hole for the rearmost bed bolt.
So today the rain broke long enough for some buddies to swing by and help set the bed back on the frame so i can begin!
more diesel maintenance
New spring hangars from Dorman
Installed new spring bushings as well
Made a new tailpipe hangar to replace the broken one
...and a new trailer hitch! Curt Class V, #15300. Got it on RockAuto for $180, cant beat that price for a class V hitch. And it is BEEF too, really nice heavy duty hitch.
That pretty much gets me up to date, as it has been pouring non-stop for days now.
I still need to fix the trailer hitch wiring as i damaged it when i removed the bumper (doh!) but aside from that the repairs are done, which means as soon as the weather improves, the mods can begin!
So now that the bed is off, the maintenance can begin.
#1, rear tank runs out of fuel at ¼ tank. Pulled the sending unit and sure enough, the strainer has broken off the bottom!
Pulled the front sending unit because it always read empty, and found a cracked float full of diesel
(float already removed)
Sending units for the diesels are pretty pricey, but fortunately, parts are not! So i ordered a new float for the front, and strainer for the back off Amazon, and got them both fixed
Next up was to remove the front spring hangars as they are toast
From there i needle-scaled, wire-wheeled, and then primed the whole back half of the frame
And then yesterday i finally got a coat of paint on it!
The diesel gets upgrades!
Woah an update!
So here we are, 3 years later. Everything still works! Sort of, anyway. This thing needs some TLC tho, so here we go!!
Step one, remove tailgate & bumper:
Step two, remove rotted out, worn out trailer hitch:
Locate bed bolts in bed liner (this part sucks)
This one was particularly stubborn, had to cut bottom of bolt off. They have an interesting shoulder on them so as to not crush the bed when torqued down; also means they must come out the top even when the head is cut off.
Front-left bolt. Another stubborn one. This one i had to cut the nut off with a die grinder, due to how close it is to the fuel & brake lines
This is a fun job to do. 5 out of 6 bed bolts fought me, and ended up getting cut. Im still going to have to deal with this later!
So much scale falling on me the whole time too.
Then a couple buddies stopped by, and this happened!
Bed is on trailer for now. Yes, its going back on.
