The Stovebolt Site Forums The Parking Lot Big Bolts Wanted: Close up photos of a dump bed for a Loadmaster

Does anyone have any close up photos of their dump bed. I would like to make mine like orriginal.
It would be greatly appreciated.

Aloha,

Keoni

I've got a 48 1 1/2 ton with a dump box. I'll be using it tomorrow too. I snap a few shot of the mechanism while it's up. Anything in particular you want to see?
Scott

Thanks Scott,

If you could get a shot of how the pump and rams are installed and how the edge of the bed looks that would be great. Also if you have any shots of how the levers are in the cab would be wonderful too.

Much Mahalo,

Keoni

I sent you a few pics via e-mail. Let me know if you want anything else.
Scott

Here's one that I sent you, maybe someone else has a different sent-up. There's alot of different makers out there. Anyone else?

My 49 fjord is set up thr same way.

Scott, two mud tires on one side and two road tires on the other? You could even that out.

I could, but I don't use it much in the snow. The future plan is to put the staight tires on the front and buy 4 traction tires for the rear. As is stands now, the dump truck is third on the list to hit the shop. Hopefully it won't be too long,

You had asked about levers in the cab. A lot of those hoists are set up, not with levers, but with cables. They are like oversized choke cables. One runs the PTO, and the other goes to the control valve on the hoist, using the appropriate linkage, etc. The advantage is that the cables can be mounted under the dash, or wherever it is convenient. When levers are used, you generally end up chopping holes in the floor where the levers come through. My '47 Loadmaster has such a hole where both levers come through. It looks like it was put in with a can opener--or a dull axe!! It's 3 times bigger than it needs to be, and looks like h---! Not to mention it's drafty, and exhaust gases come in, etc. I plan to replace the levers with cables so I can fix the floor. I think you might be happier if you went that route also. Good luck with your project!

From the photo above in this thread I can see that the hoist is likely a Perfection model 715 LP or a Galion 715. It has no subframe as such, only an angle running forward for attachment. These were used on early 40's-60's trucks as conversion hoists for platform bodies and farm bodies. The photo looks to be a wood floor so I am assuming it is a platform body.

DUMP BODY hoists on the other hand had a 4-5" high channel subframe which ran the full length of the hoist and the hinge area was part of it.
The cylinder was pushing against a tri-angular lift arm arrangement or cast iron cam & roller setup(Converto Mfg. only). These were usually a little longer stroke cylinder (approx. 20") for an 8' dump body. The bodies were typically 8'L x 78"W (ID)and about 16-22" high. The front bulkhead and tailgates were typically 6" higher than the sides. This would have made them 3-4 yd capacity. This is for the small "2 ton" size chassis that used 7:50 & 8:25 x 20 tires and had 60" C/A dimensions. Larger chassis were typically 9-10' long bodies of 72"-84" C/A dimensions for single axle trucks. These subframe hoists were originally made to stiffen the truck frame and caused the bodies to set higher for added tire clearance.

Nearly ALL the bodies of that era were made of 10 ga. mold steel and used 3" or 4" channel crossmembers on 12"-16" ctrs. Most all had flat rubrails and tapered sideposts of various designs that were either skip or solid welded to the side sheet. Floors generally had a center full length seam and ALL had a flat top rail of either 2 or 3 bend design. Tailgates were also 10 ga. and had either one horizontal formed brace or two vertical formed braces. Hinges were usually made from cast iron and the lower hardware latched up on tailgate lower pin from the bottom side, but occassionally one would see it closing downward from the top as is done today. Hardware operators were cast iron and located at the front drivers side. These were simple over-center designs and had threaded 1/2" rod and clevis at the rear where they attached to the cross-shaft.

I may still have some old literature in my files from thses days but not likely after so many years. I have been in the business for 40 years and have worked on dozens of these old things. The pumps were low-pressure (1000 psi) and were cast iron gear type that ran directly off a PTO shaft from the tranny. ALL the 40-50's units used floor levers and these were still popular and considered standard equipment well into the 70's.
CABLE operators were not of sufficient strength or reliability to operate the pump valves until late 70-early 80's. Also NONE of those early PTO's had provisions for attaching a cable operator in those early years. All were a shift rod design. PTO's were Chelsea, GarWood, Tulsa and later on Muncie. All were cast iron and nearly always a single gear type.

Hope some of this information is of value to you. Believe me, it is all accurate and I paid my dues to learn it.

The truck above is a '48 4400 with a 12' grainbox (the wood floor) that I've hauled up to 8 tons of gravel and dirt on. I seemed to have forgotten those little details before,
Scott

This info is helpfull for me as well. I have a 49 with a bump bed that utilizes 2 rams and no levers just cables for the PTO and valve. Does this mean that my dump is a post 1980 install???

Good info, 53moneypit -- can I make a tech tip out of it?

Regards,
John

Certainly Stovebolt Staff, you can use the info anyway it is helpful.

Now, as to ND19493800's question about his hoist possibly being a post 1980 installation, well how can I say. Here is what I can tell you however. If it has twin cylinders and is of 1949 era, i.e., an original hoist, then it is definately NOT a dumpbody hoist but rather it is aconversion hoist commonly used on grain bodies, etc. Glencoe was a popular product as was Perfection-Cobey and a few lesser known brands. (Johnson, Galion, Marion to name a few) Interestingly none of these companies are in business today. Two of the brand names still exist, Galion and Perfection, but are only shadows of their former selves and the product lines are vastly different from the 40's-80's.

If your hoist has a Williams pump/valve/reservoir assembly in one unit then it was made for a cable control but these weren't available in the 40's, only cast iron gear pumps as I have previously stated. The inexpensive Williams unit was and is common on conversion hoists manufactured after approximately 1970. Cables became popular on PTO's in the 70's. Either of these two, the pump or the PTO could have easily been replaced over the years so it is really impossible to say if your unit was installed after 1980.

Hey guys,

Thanks so much for all the info and thanks Scott for the photos, great help!
I just received the orriginal hydrolic system and frame but I believe I am missing parts. The parts I just got are the sub frame which the resiviour bolts to and also the dump frame. I have the drive shaft for the PTO and the pump attachment for the other side of the drive shaft. The cylinders are a dual ram set up but I do not know where it bolts to. I see where the tips of the rams bolt to, It bolts to the dump frame with a 1" pin from each ram. I will try and get some photos of the parts. I don't have the triangle piece that Scott has in his photo, is this the piece I am missing?

Thanks again people, you guys are the greatest!

ND19493800, Do you have any photo's on your dual ram system? If so could you post 'em?

Thanks,

Keoni

Sorry UR2SLO, The dump is not working. I did find out that it is a Galion. When I get it working I will send you some photos.

ur2 slo: Perhaps I have not made myself clear enough on what you have. Yours is a conversion hoist and does not use the lift arm [censored]'y that you mention above as not having. It shouldn't be there. Your cylinders attach to the body underframe longsills by means of an angle or perhaps a shaft passing through the top eyes of each cylinder.

I see a lot of wood on the body which leads me to believe it is a home-made arrangement. IF the longsills are heavy enough you can bolt a 2-3' steel plate on each side of the longsill to make a sandwich type upper bracket to attach the cylinders to. This needs to be done on each longsill obviously If you have the subframe and lower cylinder attaching points then the top will locate itself between the longsills and the crossmembers. Best bet is for a solid steel understructure but oak or a similar hardwood could be used for light duty situations.

Find yourself a good truck equipment shop on the islands and go see him if your still unsure. :rolleyes:
