Hello,
I have gotten my hands on a Waldon 7000 loader which I think is a 1995 model. Although, I believe the engine is newer than that(1999?) due to the in-line Bosch injection pump, rather than the rotary style shown in the parts book for the 1995. But that may be another thread.
Anyway, i only know a partial history of the loader and it supposedly ran when it was parked due to an upgrade at the plant. I plan to use it around my farm.
After initially getting it started, the rack stuck and it ran away. I did get it shut down fairly quickly, but I have not been able to verify any loader functionality yet. Injection pump was rebuilt, injectors checked, lift pump and shut off solenoid replaced and fuel tank cleaned. So engine wise, I am very close to starting it up once I get it wired up and the injection pump back in it.
The wiring on the loader was a complete mess. Half the dash was gone, and at some point the main harness had wrapped around the driveshaft and did not win that battle. A fast and dirty repair was done but basically, all that was still connected was forward/reverse and the starter. And at some point, the original joystick electric over hydraulic bucket controls where switched out with a conventional 2 spool valve.
Fortunately I have a parts manual which includes the wiring diagram, however I do not have a service manual.
But to the basis of my questions...
The tram motors and speed controls. The motor/valve in the very front has two solenoids on it(top and right side). One is the Dynamic braking, and the other is for the front motor Shift Override. I am not sure which one is which. The Dynamic Braking gets voltage whenever the loader is in Forward, and the Shift Override is/was connected to the "C"(common?) of the 3 position rotary switch(Low/Mid/Auto).
The "L" terminal of the 3 way switch shows connecting to the rear motor Shift Override. Along with a diode back to the common terminal. There is ignition power applied to the "B" terminal of the switch. There is a "R" terminal that is not connected.
There is a small free standing solenoid valve just behind the steps on the left side of the cab. Parts book shows it is a "Shift Valve" and connects mainly between the pump and the rear motor. I assume that is the rear motor Shift Override.
So...
Which of the two front motor solenoids are which and is there an operational explanation of them?
Is the rear motor solenoid the one I think it is? How does it operate?
Would anyone have an operational explanation of the 3 modes - Low-Mid-Auto"? I am not sure which terminal corresponds with which mode selection.
Does applying the brake somehow work as a de-clutch for the drive motors?
What type of diode do I need for the 3 way switch? Is it the same diode used on the starter interlock relay?
Anyone have a service manual for it? I think the frame sn is 23938
Lastly, Thank you.
