Lately I've been attending to various small items. Eg, instruments, which require CAD drawings of the faces to be made to be sent to the instrument repair man, as most of my gauges are repairable and the major cost is screen printing new faces. Hmmm, time consuming.
And I've started a closer look at the wiring in the cabin. There are three looms there:- main, that goes from the terminal block to the switches/gauges; dipper, that goes from the terminal block to the dipper switch (that wasn't difficult!!) ; and charging, that goes from the regulator to the gauges and generator.
But here a few other bits and pieces.
The pintle hook came from another truck, a wreck on a dis-used mine site in the outback. The shaft was bent part-way along, how it got bent there, I don't know. Perhaps it was used when not properly assembled in its' mounts. Anyway, the press fixed that.
The next problem was that the end of the hook had been reduced, presumably to recieve a much smaller ring, or more likely, a hole in a flat plate. So that was welded up and ground then flapper-disc'ed to shape.
I've also started on the torque rods. There are eight of them, four of fixed length and four adjustable length. This makes it an eight-rod suspension, of the "new-way" style. The heavy wrecker is a six-rod suspension, none of them are adjustable, their mounts are instead.
To dis-assemble the adjustable ones took a large pipe wrench and a good vise. The best vise I have at this time is the one I made a bracket for to go on the Heavy Wrecker vise-bracket. A good excuse to get the Kenworth out!
The fixed-length ones are mounted at the bottom of the suspension and have a ball joint with a tapered pin, like a tie-rod end on a car. They are apparently packed with a material like webbing. Anyway, one was dodgy, but I managed to get a NOS replacement end for the adjustable rod, and just pressed the worn one out and the NOS one back into the non-adjustable rod.
The adjustable rods have a ball-and-tapered-pin on one end, and a vulcanized bush on the other end. Although these ends are designed to be replaced as a unit, I pressed the vulcanized bush out for a closer look.
I used a press plate that I had cut out to size by laser cutting, and a 3/4" drive socket to fit. Worked fine.
The bush can be seen to have a dislodged rubber. It was like that on the truck.
I have found some replacements that fit, but are a little different design. Perhaps post-war design. I'm going to see what is involved in having them re-vulcanized.
Does anyone have any ideas/suggestions that could help with any of this?
That's all for now. bye, Sam.
