I've read all the stuff from past posts. After reading what Fast Fred Said, I went back to the drawing board and I think I've got a simple cable actuated system that will work. I haven't built it yet mind you but I've drawn it up and have all the parts including a spar valve. I will make a mock-up and then install on my 4106. Mr FF, I would like to send you a drawing and see what you think if you don't mind (or to any one else who carez to). |

Hi Joe
I would like to have a look at your idea. |

The big hassle with cable is the controll end will only move about 4 inches total, so to have the system work at all times/full throw the controll will need to be mounted mid way out the leveling sensor arm.
Locking cable handles are off the shelf.
The cable end will point up , so a better seal may be needed. There common on steering cables , but not on shift or controll cables.

In my opinion, the drawback to using this system lies in the fact that you end up with 2 methods of levelling (auto and manual) that both use the same air supply and the same valves. So, if you have a levelling valve that malfunctions, or a leaking line feeding it, you are out of business.
The dual systems used by most folks give you two separate and distinct methods of leveling - and a manual backup system in the event of automatic leveling valve failure. This is the design on my drawing board right now.

I am not familure with the dual system "used by most folks" but would like to know more. |

My primary objectives include simplicity and using the existing valves without replumbing and installing solenoid valves. I am also not interested in routing and maintaining long runs of control cable, am not bent on making adjustments from the drivers seat, and don’t object to having to adjust the height from out side the bus, as must of the time height adjustment will be in a parked condition anyway. My design allows use of the full travel of 6.5 inches required for lowering 4.5 inches and raising 2 inches. I use a standard bicycle brake cable & housing and soft copper tubing for cable turns. Also the cable housing faces down so that contaminates are less likely to accumulate in the cable housing. The adjustment for the rear wheels will be made from inside the aft bay while the adjuster for the front will be located inside the bus in the stair well area. If I do need to adjust height for road or overhead clearance, I can stop the bus, get out and make the adjustment and then continue. And instead of “Locking cable handles” I am planning to use a very simple locking cable pulley which I have accumulated the parts for fabrication. FF please e-mial me direct. |
