tc40a lift arm leaks down

[motorhead704]

just got a tc40a after using it for a while the lift arms started leaking down . It is a 2006 model it leaks down slowly while engine is running is this problem in the pump or the lift arm seals. I don't know much about front end loader. thanks for any help

Are you asking about the three point hitch lower arms or the loader arms? How long does it take for the lowering with no added weight?

it is the loader arms. with no weight in the bucket it takes a while to leak down. if you have weight in the bucket you can see it leaking down to a point and then it seems to stop.It lifts and lower ok but it seems a little weak

Disconnect the quick connects.
If it leaks down it is in the cylinders.
If is does not leak down it is in the SCV.

To reconnect the quick connects you have to release the pressure.
crack open the line ( fluid will leak out) or use a lift to raise the bucket.
When the hydraulic pressure is off of the connector it will reconnect easily.
