Hell all:
We are running with a problem in our grease pump (Lincoln HTL 101) use in a hydraulic hammer Doosan DXB170H (have the part list).
At first the pump was not delivering the grease to the hammer. Later noticed that grease type was the wrong one (were using the normal grey one) and now the pump is leaking hydr oil from the cover.
So we took it out and made some surgery.
This is the pump
So I removed the black cover:
. The flow from hydr oil is restricted and goes to a stepper motor that pushes a pin and moves the eccentric shaft.
Pic below shows where the eccentric shaft goes.
Took the nut with the pin out and you can see the shaft
I removed the shaft to see if there´re some o-rings or something
But nothing
Can see anything thru the hole.
Anyway, I will put a video to show how it works
