Ever since I got it, my 1992 F250 has had a bad wiper motor. The symptom, which can be caused by several different kinds of faults, is that it didn't "park". That is to say, the switch turned the wiper motor on and off, regardless of setting. High speed always worked, but park never did. I proved that the motor was the problem by taking off the cover and cleaning the contacts, and having it work for a short time. Rather than fight corrosion and continually shave switch contacts, I decided to drop the forty bucks retail on a new window motor.
The fuel injection system on the classic 6.9 and 7.3 liter International-Navistar engine used in diesel fords from the 70s to the early nineties is relatively simple, but some confusion still remains about how it functions. The major components of the system are the lift pump, filter head and filter, fuel injection pump, fuel injectors, return system, selector valve, and the fuel tanks.
The fun, it burns. And it never stops, either.
In the last few days the Ford's had new batteries and some cable soldering work done, eliminating two of the four lead terminals and replacing them with the stamped steel lead-free style. The Mercedes, meanwhile, has had an '83 (or was it '84?) W123 300D turbo rebuilt and installed, along with a manual boost controller, W123 air filter housing which I still need to modify to take the W126 cold air intake, and VDO boost and voltage gauges. The voltage gauge is just something I had around, and it's taking up space until I get a VDO pyrometer to go in there; it's never a good idea to turn your turbo up without a pyro.
I have finally concluded the repair of my 1992 Ford F-250's steering system. I say "repair" but "replacement" is a more honest description, as I have replaced everything but the intermediate shaft. I find it interesting that this component is in such apparently good shape (it slides and rotates without any sound or feeling of friction) when everything else in the system was shot, especially since several Diesel Stop members have complained about its failure.
When I bought a 1992 7.3 4x4 with a turbo that leaked from every pore I knew it was going to be an ongoing hassle, and this last week I ended up diving into the steering system. I was having problems with nearly every part of it, and I'm still not done. Right now I'm rebuilding the steering column.
Today I managed a successful test drive of my pickup after reinstallation of the aft fuel tank, in which I have replaced the broken rubber pickup with a short piece of Gates multi-fuel compatible fuel line (3/8" ID.) This time I made it to town and back without mishap. It was actually fairly amazing how quickly the truck started up; I didn't do any air bleeding until after I got back.
