Hey Guys-
So my D17 Series 1's rear lift has ceased function, and the reservoir is low, I added a little bit, and it operated slightly, and the reservoir level fell, and the rearend level went up, so I got the typical blown hose or cylinder seal.
Which I'll make a 'winter project' of... but for the moment, I need it for other things.
The issue I forsee, however, is that the pump is a demand-control device which is mechanically unloaded when pump pressure hits the unloading limit.
In most contexts, this means that a pump that has insufficient source fluid will never reach unloading pressure, hence it will continue to TRY to pump, sans fluid, until there's nothing left of the pump.
I SUSPECT that this might be the case of the D17 Series 1's setup, and I do NOT wish to damage the pump, so what I've done is placed the lift lever in the full DOWN position, and added fluid to the reservoir, to keep that pump wet.
Is this a satisfactory action for the pump's actual operation, or is it unnecessary, or is it futile? Will the pump burn up ANYWAY, or will it be fine regardless??
I'll be using it with the backhoe attachment for the next two months-or-so, which absolves need for the lift or high-pressure system, because the backhoe runs off PTO pump.
