I noticed your other thread about the linkage or feedback rod for 3PH........
Just wondering bypass issue with recent 3PH problem and now BH.....
I'd also double-check backhoe connections to make sure everything is seated correctly. Since you had 3PH issues, would seem the backhoe was just put on recently.........
I'm curious about an association between the 2 issues. If loader/3 PH work right, tells me something isn't plumbed right to the BH.
Good luck!!
Good Call RCW!
I didn't associate/look to see if it was the same OP!
QC's are a very common source of hydraulic problems and very worthy of checking first up!
Flow rate = speed, Pressure = lift capacity,
GENERALLY, if a QC is not seated correctly and still allows some flow, it will reduce speed of operation, but not it's final lift capacity, albeit getting there slowly.
HOWEVER, if a QC is limiting flow, it can allow the relief to go into bypass due to the the fluid on the opposite side of the cylinder not being able to escape at a reasonable rate or reducing or blocking flow in one direction and not the other, thereby creating similar symptoms, so very much a possibility.
Ideally he should also ensure his 3PH is set down when using the hoe,(including draft control) just to make sure nothing can build up pressure if a valves is bypassing.
FEL should also be checked to ensure it's centered, as well as any remotes as mentioned earlier.
Depending on the setup of the backhoe valve and ultimately the hydraulic circuit when the hoe is added, the relief on the hoe valve may also come into play, depending if it's an over pressure relief set higher than the main tractor relief, or not.
To OP, when you now try to lift your genset, do you hear the hydraulics going into relief? Is your dipper or boom extended further than previous times, a little change in extension will reduce lifting capacity greatly. Will the FEL still pick up a heaped load of gravel/dirt easily?
Go with the easy checks mentioned my RCW first.
Anybody have a wsm?
