I have been changing the Hydroback cable (tram pump cable) about every 400 hours on my 1430 - they seem to break at about that time. Not sure why, but I certainly do a lot of shuttle work moving and placing rocks and handling materials so it gets a lot of exercise. I had been buying them from PT but this last time I decided to get a couple on hand since the machine is approaching 1600 hours. I ended up purchasing two for less than one from PT, and all I had to do was spec the ends and length and then get a quote while on line. On my PT the cable only has a 2" travel, and that dictates the dimensions of the bulkhead end fittings, which must fit the hydroback spring centering device, and the overall length was 84". the Cable type is a 40 series standard armored core design. I installed one yesterday (before the old one failed this time) and it works fine - on the 1430 when the cable fails you lose forward tram capability (the pull direction on the cable) but still have reverse since the cable can still push even when the core is broken. The failure mode is a good thing since I usually am working in places where the way to safety is reverse!! Anyone who mows or handles material on slopes or near the edge of a drop might want to think about what would happen should the cable fail - you might want to factor that into your manuvering strategy!
The source is:
Cable Assemblies - Midwest Control Products Corp. - and it only took about 15 minutes to spec and order the cable and it arrived in about a week and half since it was not a stock item. Special orders are not returnable, so be sure you measure and design your cable carefully - I had an old broken one to use for measurements.
