I have a thread around here somewhere with part-numbers and such on how I replaced my original 1985 cable.
Although it worked somewhat for many years/miles, I was never impressed with my original cable, as it hung full-throttle a number of times for no apparent reason, even way back when the truck was almost new, and was a water magnet that would freeze up while going down the road in freezing weather.
Mine never completely broke; however, a bunch of strands did break and became a big steel wire fuzz-ball that would catch in the open end of the sheath.
My intentions were and still are to retrofit a 379 Peterbilt pedal/cable; but, under pressure of time, I got an aftermarket cable from Amazon and doctored it up somewhat prior to installing it.
First thing to go was that hateful binding red plastic sleeve.
Then, I pumped hot oil through and through the sheath.
As the new cable was a few inches longer than the original, I was able to zip-tie the slack up high-and-dry, creating a self-draining arch along it's length, where water will hopefully drain away, instead of collecting and freezing.
My original cable had stretched some four-plus inches in length over the years, necessitating me having to crimp split-shot sinkers above the pedal connection every couple years or so to maintain throttle travel.
With the new cable installed, I stripped out the old cable from it's sheathing and replaced it with one robbed from an old ten-speed bicycle, crimping cable slugs onto the proper places.
The inexpensive bicycle cabling was of much superior quality to that originally in the throttle cable.
This re-built cable got the same oil treatment and resides underneath the sleeper mattress in the event that the new cable should fail.
