Hi all Again a little progress. I started with the brake system. I decided to work out a two hose system for the trailer even if the truck is from a time a one hose system was normal. I thought about that story: because of safety they changed the brake system of the truck in the mid seventies. And so here are the components: The front quick release valve with plumbing for the front axel The treadle valve with plumbing the linkage to the foot pedal is missing The trailer protection valve with plumbing The quick release valve with plumbing for the rear axel The air reservoirs with the water drain valves and the plumbing And the alcohol evaporator for the cold time Here you can see a part of the plumbing for the steering system There are a lot more of things to be done as plumbing on the brake system, so next week more about it. So long Arnd

Arnd, This just keeps getting beter and better. But I do have a question. Knowing that you do a lot of research on your subjects. Would a truck that old have power steering? Or was it added later on? Either way I love the detail you are putting into this model.
Be Well Gator

Hi Gator
Well you are totally right it is not the one you normally will find on such a truck of that age. I have to say that the truck originally had a power steering system in the 50’es too. Probably it was something optional and not standard. My information tells me that it was a hydraulic cylinder which was mounted between the frame and the tie rod. A pump on the engine for the pressure the cylinder for the mechanical movement and on the steering box was a gauge system that moved the pressure from one side of the cylinder to the other on like the way you turned the steering wheel. As far as I wasn’t sure if that system would be ok for such a heavy truck I decided to use something else like the steering system from an Autocar which is much heavier. I hope it is ok and some one out there could have used it like this. So long Arnd

Hi all I worked last night a bit on my old lady. The brake system is now totally plumbed and finished. I added the two hand valves for the trailer. They are from AITM and were reworked to fit as real ones. I drilled a little hole in each one and put a pin in to one of them. So you can couple them together like real ones and they stay together. The next step will be the electrical wires and rest work I have to do on the cab and hood. As got some more information yesterday on all that logging trucks I pulled out my home made logger and made some pictures to compare this two trucks. It is or better said it should be a 1960 Hayes Clipper with a self made front used for heavy logging off highway. So long Arnd

Arnd,
The pump was controled by what was called a williams electrical switch which was mounted under the dash of the rig usually on the right side of the driver. I've seen the pump itself installed directly to the bottom of the tank or it was set inside the frame of the truck and many other places which was handy. The lines ran out to the drive axles and another line ran out to the trailer. The switch controled either the trailer, Truck or both.
Tufftin can explain this better to you if you contact him. In some cases such as Off Highway rigs a prassure line was run off the main air system to preasurize the tank to increase the water flow and ward off any air bublbes in the water lines. A vacume block in the water pump would quickley burn it out and cause brake cooling failure.

I have only ran the air type brake water lines. The control valve by Williams is mounted under the dash and you control the amount of air pumped into the tank. It isn't a lot of air as we use to run 5 to 10 pounds of pressure.. Then you have a hand valve to set the air. There is another hand valve to set where you want the water..........truck, trailer or both. Then it's simply running lines to the top of the brake drums so the water can cool the iron. A simple quick connect is used to run to the trailer with one hose and then, like the truck, when you reach the area, you manifold it into a 4 way split to reach the drums. There is a picture on the forum somewhere that I posted before of a Williams dash set up. Hope this helps. Mike

Went back and found the picture of the dash pod. Guage is for air pressure. Mike Hosted on Fotki
