Hydroback Cable

[J_J]

I received my cable today, and it looks just a Morse heavy duty control cable. The only numbers that are on it are M15140 1629 . Both ends are the same. The M may stand for Morse, I will try and verify. I think what I will do is to connect both cables with long treaded nut and slick it up with cable lube and pull it through the tunnel. Just hope it does not jam up in the tunnel and scrape the hyd hoses or rip some wires out.

Well, I installed the new control cable for the Hydroback. I hooked everything like I said above, and pushed on one end and pulled on the other end. Easy job, took about 5 min after I connected the two cables together. I ran around town for about 4 hrs, looking for a 1/4 x 28 threaded coupling, and the cable ball joints . I couldn't find a coupling, so I cut one off the old ball joint, and threaded them together, and slipped some tubing over the joint to make the cable about the same size. I will have to call Terry on the instructions to adjust the Hydroback. Does anyone know if the adjustments are the same for all Hydrobacks?

My hydroback cable stuck a little today and I had to hit the reverse petal to stop. Has anyone tried lubing this cable? Did it work. I am tempted to lube it and order a new one as a spare. I hate to have this thing non-operational. About 850 hours on the machine.

Yup, I lubed the one on my 1850 this spring when I found it nearly frozen after sitting all winter. I used the spray can of Case chain lube I had handy to give it a real good squirt along the rod on the forward end and it feed up fairly well after working it back and forth a few times. By the time I had a few hours on it this summer the lube had worked its way through the jacket and all was fine for the rest of the summer. My guess is I'll have to repeat it again next spring, especially if I forget to give it a squirt this fall

All Hydroback operated PT's owners. Did you know that you can order a Hydroback unit with a spring center pressure of 10 lbs or 20 lbs. Which means, that is the pressure used to keep the pedal and transmission in neutral. Does anyone have an adjusting bolt under the left side of the pedal to limit reverse speed?

Does anyone know how the Hydroback works. Actually, very simple. There is one spring inside of another spring. One spring pushes on the cable housing, and the other spring pushing on the cable, therefore keeping what ever is attached, centered. When you push down on the right side of the pedal to go fwd, one spring is compressed, and when you push on the left side of the pedal, the other spring is compressed. No pressure on the pedal on the foot pedal, the transmission is in neutral, and wheels not turning.

Thanks J_J. I was hoping you would reply.

Thanks JJ, do we know which we use the 10 or 20 pound?

Also anyone able to post pictures of the hydraulic replacement for the hydroback cable--as used on the new machines?
Thanks

I asked that same question, and no one has answered yet.. Would like pictures if available, and technical description if known. I don't even know what to call that unit.

I would use the 20lb unit. It should self-center better, and the difference between 10 and 20lbs is pretty small for a foot-operated control.

I bought my 425 pt in late 203 and they don't have a hydroback cable, they have a valve.
