Main hydraulic pump question (MF175)

Camozzi04 · May 28, 2020

Hello,
I have two hydraulic pumps. Question: How does the main pump supply the 3pt lift cover with hydraulic fluid? I see no line attached, only a tube that s capped off on the lift cover for external hydraulics in front of the seat. Maybe I m missing a tube or something. My 3 pt does not work!
Thanks.

Where that tube comes up to lift cover is
ported to provide pressure for the lift
arms.

The tube with the square block in the photo does NOT have it's lower end in the pump port either. That tube should stay with the lift cover when removed as it's hooked to the pressure control valve. Someone must have changed the system as there's a relief valve added to the pump. If the tube WAS in place when the cover was on, then there's something wrong with the pump. Start the tractor with oil up to the lower side cover bolt hole and move the roller lever back and forth, you should see oil come out the port off and on.
