My partner and I just bought a Link-Belt LS-4300 CII excavator ( s/n C810.464) that had sat for about 4 years on the property next to ours. It has the Isuzu 6 cylinder diesel motor that runs strong and clean, and the hydraulics and tracks are in reasonably good condition. But it had been abused and had systems bypassed, the throttle control and engine shutdown switch removed, and other interlocks bypassed. It was shut down when it suddenly no longer was able to engage the hydraulic drive or boom circuits though the pump appears to be putting up full pressure, and the hydraulic tank is showing air pressure of around 15 lbs.. We have the manuals and are slowly digesting the the systems theory of operation. But we'd like to at least move it over to our property and continue sorting things out until it's running correctly again. We haven't found any mechanical controls for the engine throttle or shutdown, and have been manually controlling the injector pump from atop the engine bay. Is there a manual means of doing this without the electrical control? We don't have the systems display panel that is shown in the diagrams, and there doesn't appear to be any wiring harness running up the right front of the cab as would be expected. It seems to have been run "bare-bones" up until it was parked. Nothing has been removed from it since last ran, so what we have is what was operational until parked. We have a lot to learn but are hoping someone on this forum can point us in the right direction to manually override things in order to move it. And knowing a good source of new and used parts would be a terrific help too. Thanks, -Tom
